This plugin references an SSH private-key path or a private-key file header ("-----BEGIN RSA PRIVATE KEY-----\nMIIBOwIBAAJBAK…). An SSH private key authenticates you to servers and Git remotes, so code that reads it can impersonate you wherever that key is trusted.
- Delete any direct read of id_rsa / id_ed25519 or other key files.
- Authenticate through the SSH agent or `git` so the private key never enters plugin memory or an outbound request.

llm-cli-gateway
_"Without consultation, plans are frustrated, but with many counselors they succeed."_ — Proverbs 15:22 (LSB)
A Model Context Protocol (MCP) gateway for running Claude Code, Codex, Gemini, Grok, and Mistral (Vibe) CLIs from one MCP endpoint, with durable async jobs, session continuity, cache-aware prompting, observability, and personal-appliance setup tooling.
Why developers try it: one local MCP endpoint for cross-LLM validation, multi-agent coding workflows, and repeatable assistant-led setup across five provider CLIs.
Current signals: CI and security workflows pass on main, OpenSSF Scorecard is published, OpenSSF Best Practices is passing, releases use Sigstore signing, and the package is MIT licensed.
Quick Start
npm install -g llm-cli-gatewayOr use directly with npx from an MCP client:
{
"mcpServers": {
"llm-gateway": {
"command": "npx",
"args": ["-y", "llm-cli-gateway"]
}
}
}What It Provides Today
llm-cli-gateway is a single-user MCP gateway for cross-LLM validation and multi-agent coding workflows. It is more than a thin CLI wrapper:
- Runs five provider CLIs through consistent sync and async MCP tools.
- Persists long-running jobs, supports restart-safe result collection, deduplication, cancellation, and sync-to-async deferral.
- Tracks sessions, real CLI resume paths, structured response metadata, and cache telemetry.
- Supports cache-aware
promptParts, including explicit Claudecache_controlwhen opted in. - Can run requests inside gateway-managed git worktrees for isolated multi-agent review and implementation loops.
- Ships personal-appliance setup surfaces: HTTP transport with bearer-token auth,
doctor --json, setup UI artifacts, provider setup snippets, Docker fallback, and checked release bundles. - Remote web connectors use MCP OAuth discovery and authorization-code setup with static client or shared-secret gates. Client secrets are generated locally, stored only as hashes, and printed only by explicit copy-once commands.
- Provider CLI requests can select registered workspaces by alias via
workspace; every HTTP/tunnel request must use a registered alias, session workspace, or[workspaces].defaultbefore provider execution. Local unrestricted filesystem access is the stdio transport.
Workflow Assets
The repo ships agent-ready workflow skills under .agents/skills for async orchestration, session continuity, multi-LLM review, implement-review-fix loops, and secure approval-gated dispatch. Machine-readable DAG-TOML plans live under docs/plans and setup/install-plan.dag.toml for workflows that need deterministic sequencing and verification gates.
The next documentation focus is provider-specific skill and DAG-TOML pairs for each outbound CLI: Claude, Codex, Gemini, Grok, and Mistral Vibe. The implementation plan is tracked in docs/plans/provider-workflow-assets.dag.toml, with each provider asset expected to cover install/login checks, session behavior, approval modes, cache/telemetry surfaces, failure modes, and a smoke-test gate.
Trust & Supply Chain
- CI runs build, lint, format, tests, package checks, and npm audit.
- Security CI runs actionlint, zizmor, shellcheck, typos, osv-scanner, gitleaks, and lychee.
- GitHub release installer artifacts are checksummed and signed with Sigstore keyless signing.
- npm releases use provenance through OIDC trusted publishing.
- The npm package intentionally ships a generated, prod-only
npm-shrinkwrap.jsonso registry installs resolve the audited release tree. Release gates regenerate it frompackage-lock.json, compare for parity, and run a registry-fidelity consumer install before publishing. - Socket behavioural alerts are documented in
socket.ymland under "Security Considerations" below.shellAccessandshrinkwrapare reviewed package capabilities/configuration for this CLI appliance, not hidden install behaviour.
Personal MCP Appliance
The personal-appliance contract keeps that surface intentionally narrow: one trusted user runs the gateway on a machine or volume they own, connects one MCP endpoint, and asks any connected client for cross-LLM validation.
The product contract is documented in docs/personal-mcp/PRODUCT_CONTRACT.md. It defines the single-user scope, security posture, target support matrix, and provider-support verification gates. Public setup guides must not claim ChatGPT, Claude web, Claude Desktop, Codex, Gemini CLI, Gemini web, or Grok inbound support until the corresponding provider/client path has been verified.
This project does not provide hosted multi-tenant credential custody. Provider credentials stay on the user's machine or user-owned deployment volume.
Release-readiness history is tracked in docs/personal-mcp/RELEASE_READINESS.md. Dogfooding evidence (which target LLMs guided setup, what unsafe suggestions were captured, and which findings were deferred from the initial personal-appliance rollout) is in docs/personal-mcp/DOGFOODING_RESULTS.md.
Current personal-appliance artifacts include:
- Streamable HTTP startup:
LLM_GATEWAY_AUTH_TOKEN=<token> npm run start:http - Machine-readable diagnostics:
npm run doctor - Go bootstrapper:
installer/withsetup,doctor --json,start,stop,status,repair,upgrade,uninstall,print-client-config, and verified bundle download commands. - Release packaging: the release workflow builds Linux binaries on the local self-hosted runner, builds Windows/macOS binaries on GitHub-hosted runners, then publishes checksummed platform bundles with the gateway, production dependencies, and a managed Node runtime; see installer/packaging/README.md.
- Docker Compose fallback: docker/personal.compose.yml + docker/Dockerfile.personal for users who already manage containers.
- Local setup UI artifact: setup/ui/index.html
- Provider setup snippets: setup/providers/
- Cross-validation tools:
validate_with_models,second_opinion,compare_answers,red_team_review,consensus_check,ask_model,synthesize_validation,job_status, andjob_result.

Core Capabilities
- Multi-LLM Orchestration: Unified interface for Claude Code, Codex, Gemini, Grok, and Mistral (Vibe) CLIs
- Session Management: Track and resume conversations across all CLIs with persistent storage
- Gateway-owned worktrees: Run any sync or async provider request inside a managed git worktree, with per-session reuse and cleanup
- Token Optimization: Automatic 44% reduction on prompts, 37% on responses (opt-in)
- Correlation ID Tracking: Full request tracing across all LLM interactions
- Cross-Tool Collaboration: LLMs can use each other via MCP (validated through dogfooding)
Observability
- SQLite Flight Recorder: Every request/response logged to
~/.llm-cli-gateway/logs.dbwith correlation IDs, token usage, duration, retry counts, and circuit breaker state. Browse with Datasette:datasette ~/.llm-cli-gateway/logs.db - Structured Metadata: Tool responses include machine-readable

Cache-aware operation
Every *_request and *_request_async tool accepts an optional promptParts field that structures the prompt for better cache hit rates. The gateway concatenates the parts in canonical order (system → tools → context → task) so that the stable prefix bytes precede the volatile task tail unchanged across calls, letting each provider's automatic prompt-caching land on the same content hash each time.
{
"promptParts": {
"system": "You are a helpful code reviewer.",
"tools": "You have access to Read, Grep, Bash.",
"context": "<long stable context block — file dumps, etc.>",
"task": "Review the changes in src/foo.ts for security issues."
}
}prompt and promptParts are mutually exclusive — pass exactly one.
Per-CLI capability matrix (prefix discipline is automatic via promptParts for all; explicit levers are provider-specific):
| CLI | Prefix discipline | Explicit lever(s) | ||
|---|---|---|---|---|
| claude | yes | promptParts.cacheControl + outputFormat: "stream-json" (Anthropic cache_control breakpoints on stable blocks; ttl="1h" forced) | ||
| codex | yes | none (OpenAI implicit) | ||
| gemini | yes | none (implicit server-side) | ||
| grok | yes | compactionMode / compactionDetail (context compaction: `summary | transcript | segments; segments` writes per-segment markdown) |
| mistral | yes | none (implicit) |
Claude example (explicit cacheControl)
claude_request({
promptParts: {
system: "You are a helpful code reviewer.",
context: "<long stable file dump>",
task: "Review the diff.",
cacheControl: { system: true, context: true } // task is never marked
},
outputFormat: "stream-json"
})Gateway emits the stream-json stdin path with cache_control: {type:"ephemeral", ttl:"1h"} on marked blocks only.
Grok example (compaction)
grok_request({
promptParts: { system: "...", context: "...", task: "..." },
compactionMode: "segments",
compactionDetail: "balanced"
})Emits --compaction-mode segments --compaction-detail balanced.
See docs/personal-mcp/PROVIDER_CACHE_SURFACES.md for full surfaces, telemetry differences (e.g. Grok -p vs ACP), exact stream-json payload shapes, and cross-LLM review notes.
Opt-in flags (all default off) live under [cache_awareness] in ~/.llm-cli-gateway/config.toml.
Reliability & Performance
- Retry Logic: Exponential backoff with circuit breaker for transient failures
- Atomic File Writes: Process-specific temp files with fsync for data integrity
- Memory Limits: 50MB cap on CLI output prevents DoS attacks
- NVM Path Caching: Eliminates I/O overhead on every request
- Long-Running Jobs: Non-time-bound async execution via
*_request_async+ polling tools
Security & Quality
- Comprehensive Testing: 1,000+ tests covering unit, integration, and regression scenarios with real CLI execution
- Input Validation: Zod schemas prevent injection attacks
- No Secret Leakage: Generic session descriptions only (file permissions 0o600)
- No ReDoS: Bounded regex patterns prevent catastrophic backtracking
- Type Safety: Strict TypeScript with comprehensive error handling
- Supply-chain hardening: a dedicated
.github/workflows/security.ymlruns actionlint, zizmor, shellcheck, typos, osv-scanner, gitleaks, and lychee on every push and PR (seeSECURITY.mdfor the threat model)
Prerequisites
Node.js >= 24.4.0 is required (engines.node in package.json). The gateway uses Node's built-in node:sqlite module for persistence — there is no native binding to compile and no install scripts run. The 24.4 floor is where allowBareNamedParameters defaults to true, which the persistence layer relies on.
Before using this gateway, you need to install the CLI tools you want to use:
Claude Code CLI
# Installation instructions for Claude Code
# Visit: https://docs.anthropic.com/claude-code
npm install -g @anthropic-ai/claude-codeCodex CLI
npm install -g @openai/codex
codex loginGemini (Google Antigravity CLI)
The Gemini provider runs through Google Antigravity CLI (agy).
curl -fsSL https://antigravity.google/cli/install.sh | bash
# Docs: https://antigravity.google/docs/cli-overviewGrok Build CLI (xAI)
curl -fsSL https://x.ai/cli/install.sh | bash
grok login # OAuth flow; for headless auth, set XAI_API_KEY
# Docs: https://docs.x.ai/build/overviewMistral Vibe CLI
# Pick one — the gateway's cli_upgrade auto-detects which one you used.
curl -LsSf https://mistral.ai/vibe/install.sh | bash
pip install mistral-vibe
uv tool install mistral-vibe
brew install mistral-vibe
vibe auth login
# Current Vibe defaults session logging to enabled. If an older config disabled it,
# edit ~/.vibe/config.toml and set:
# [session_logging]
# enabled = trueVibe-specific notes:
- Model selection is via the `VIBE_ACTIVE_MODEL` environment variable —
Vibe has no --model flag. The gateway discovers ~/.vibe/config.toml / VIBE_MODELS, injects VIBE_ACTIVE_MODEL only when a model is explicitly requested or Vibe config needs recovery, and retries once after a model-not-found failure with refreshed discovery.
- `permissionMode` is the Vibe `--agent` name. Builtins are
default | plan | accept-edits | auto-approve; Vibe also accepts install-gated builtins (e.g. lean) and custom agents from ~/.vibe/agents, so any name is passed through and Vibe validates availability. The gateway's programmatic-mode default is auto-approve; pick a stricter mode explicitly if you need approval gates.
- `allowedTools` is allow-list only — the gateway emits one
--enabled-tools <tool> flag per entry. disallowedTools is accepted in the schema for caller-side parity but is silently ignored at the CLI boundary (a logger.info warning records the no-op).
- No self-update:
cli_upgrade --cli mistraldetects whether you used
pip / uv / brew and dispatches the matching upgrade command. Running vibe update is not a thing.
Installation
As an MCP server (npm)
npm install -g llm-cli-gatewayOr use directly with npx:
{
"mcpServers": {
"llm-gateway": {
"command": "npx",
"args": ["-y", "llm-cli-gateway"]
}
}
}From source
git clone https://github.com/verivus-oss/llm-cli-gateway.git
cd llm-cli-gateway
npm install
npm run buildUsage
As an MCP Server
For clients that already support local stdio MCP servers, add a configuration like:
{
"mcpServers": {
"llm-cli-gateway": {
"command": "node",
"args": ["/path/to/llm-cli-gateway/dist/index.js"]
}
}
}Stdio is the recommended path for unrestricted machine-local development access. HTTP MCP, including localhost HTTP and tunneled HTTPS, is treated as remote-capable for provider execution: provider tools must resolve a registered workspace alias, a session workspace, or [workspaces].default before spawning a CLI. Remote clients should pass relative workingDir, addDir, and include-directory values inside the selected workspace; disabling auth or using a no-auth connector path is not a filesystem bypass.
This generic stdio example is not provider-support verification for the Personal MCP Appliance. Client-specific setup guides for ChatGPT, Claude web, Claude Desktop, Codex, Gemini CLI, Gemini web, and Grok remain gated by the provider-support matrix in docs/personal-mcp/PRODUCT_CONTRACT.md.
Available Tools
#### Cross-LLM Validation Tools
The personal-appliance surface exposes simplified validation tools for non-developer clients. These tools start provider CLI jobs through the durable async job manager and return normalized provider status plus raw job references.

Workspace boundary: stdio callers may use machine-local paths directly. HTTP/tunnel callers must pass workspace or rely on a configured default/session workspace; path fields are then validated relative to that workspace. [workspaces].allow_unregistered_working_dir is a stdio/local legacy setting and does not allow arbitrary HTTP working directories or additional directories.

}#### Durable job results & automatic dedup
Every async job is persisted to a job store as it transitions through running → completed/failed/canceled. This makes the gateway a durable collection layer:
- Re-issuing a request is safe. Identical
*_request/*_request_asynccalls within the dedup window (default 1 hour) short-circuit onto the existing running or completed job — the caller gets back the same job ID instead of starting a duplicate run. This directly fixes the "agent times out polling, re-issues, and the whole job starts over" failure mode. - `llm_job_status` and `llm_job_result` work across gateway restarts. Job rows live for 30 days by default; callers can collect results long after the in-memory cache has evicted them.
- Jobs running at shutdown are marked `orphaned` on the next gateway boot (the detached child can't be reattached to). Their captured partial output remains readable.
- Pass `forceRefresh: true` on any request tool to bypass dedup and force a fresh CLI run.
##### Persistence configuration
The job-store backend is configured by ~/.llm-cli-gateway/config.toml (override with LLM_GATEWAY_CONFIG=/path/to/config.toml). Example:
[persistence]
backend = "sqlite" # "sqlite" | "memory" | "postgres" | "none"
path = "~/.llm-cli-gateway/logs.db" # for sqlite
# dsn = "postgresql://user:pw@host/db" # for postgres (interface only — impl not yet shipped)
retentionDays = 30
dedupWindowMs = 3600000
acknowledgeEphemeral = false # required to enable async tools with memory backendBackends:
- `sqlite` (default) — durable, file-backed. Safe for single-instance deployments.
- `memory` — in-process Map. Lost on gateway exit. Requires
acknowledgeEphemeral = trueto be loaded. Suitable for tests and ephemeral CI gateways. - `postgres` — interface only, implementation not yet shipped. Selecting this backend throws at startup.
- `none` — no store. *`_request_async
,llm_job_status,llm_job_result, andllm_job_cancelare NOT registered on the gateway.** This is a structural invariant: agents that try to call async tools against a gateway withbackend = "none"get a clean "tool not found" at connect time instead of silent in-memory loss after the 1-hour TTL. Usellm_process_health` to inspect the resolved persistence state programmatically.
Legacy environment variables (deprecated; emit a warning at startup):
LLM_GATEWAY_LOGS_DB/LLM_GATEWAY_JOBS_DB—noneselectsbackend = "none"; any other value selectsbackend = "sqlite"with that path.LLM_GATEWAY_JOB_RETENTION_DAYS— overridesretentionDays.LLM_GATEWAY_DEDUP_WINDOW_MS— overridesdedupWindowMs.LLM_GATEWAY_ACKNOWLEDGE_EPHEMERAL—1/true/yessetsacknowledgeEphemeral = true.
##### Per-project isolation
By default, all gateway data is global per user, not per project. With no overrides, every Claude Code window — across every repo — spawns its own gateway subprocess but they all read and write the same files:
~/.llm-cli-gateway/logs.db(async jobs + flight recorder)~/.llm-cli-gateway/sessions.json(CLI sessions)~/.llm-cli-gateway/config.toml(resolved config)
This is usually what you want — session_list from repo A shows sessions from repo B, an async job started in window A can be polled from window B, and the 1-hour dedup window catches re-issues across windows. SQLite WAL mode makes concurrent access from multiple gateway subprocesses safe.
If you instead want per-project isolation (e.g. unrelated repos shouldn't share session lists or risk false dedup hits), point each project at its own config file. In .claude/settings.local.json for the project:
{
"mcpServers": {
"llm-gateway": {
"env": {
"LLM_GATEWAY_CONFIG": "${workspaceFolder}/.gateway/config.toml"
}
}
}
}…and put a per-project config.toml in the repo:
[persistence]
backend = "sqlite"
path = "/srv/repos/.../my-repo/.gateway/logs.db"Now every gateway subprocess spawned for _this_ repo's Claude Code window reads its own config and writes to its own SQLite file; sessions, jobs, and dedup state are scoped to the repo. Other repos keep using the global default. llm_process_health.persistence.sources.configFile lets an agent confirm which config it's actually running under.
###### Agent-executable spec (DAG-TOML)
If you want an LLM agent to perform this setup deterministically — rather than reading the prose above and guessing — copy the following DAG-TOML into the repo (e.g. docs/planning/per-project-gateway-isolation.toml) and point your agent at it. The schema is agent-assurance template_kind = "implementation-dag". The agent MUST execute units in layer order, must not skip the verification unit, and must treat any failed gate as blocking.

Approval records are persisted to ~/.llm-cli-gateway/approvals.jsonl.
##### llm_request_result
Read back any persisted request — sync or async — by its correlation ID. Every response echoes its ID in structuredContent.correlationId; pass it here to recover the persisted prompt/response after the inline result is gone. Reads the flight recorder, so it works independently of async-job persistence (returns "not found" when flight recording is disabled).
Parameters:
correlationId(string, required): Correlation ID from a prior requestmaxChars(number, optional): Max chars of the persisted response to return (1,000-2,000,000)includePrompt(boolean, optional): Include the full persisted prompt text, default: false
##### llm_process_health
Report gateway process health: async-job manager state plus the resolved persistence block (backend, dbPath, config sources). Use it to confirm which config file and SQLite paths the gateway is actually running under.
##### upstream_contracts
Return the gateway's declared provider CLI contracts, optionally probing the installed binaries for drift.
Parameters:
cli(string, optional): Filter (claude|codex|gemini|grok|mistral)probeInstalled(boolean, optional, defaultfalse): Run local--helpprobes and compare advertised flags against the declared contract — strongly recommended after any provider CLI upgrade. The probe reportsmissingFlags,extraFlags,acknowledgedExtraFlags(known upstream-only flags filtered fromextraFlags),discoveredFlags, and stale-markerwarnings.
#### Session Management Tools
##### session_create
Create a new session for a specific CLI.
Parameters:
cli(string, required): CLI to create session for ("claude", "codex", "gemini", "grok", "mistral")description(string, optional): Description for the sessionsetAsActive(boolean, optional): Set as active session, default: true
Example:
{
"cli": "claude",
"description": "Code review session",
"setAsActive": true
}##### session_list
List all sessions, optionally filtered by CLI.
Parameters:
cli(string, optional): Filter by CLI ("claude", "codex", "gemini", "grok", "mistral")
Response includes:
- Total session count
- Session details (ID, CLI, description, timestamps, active status)
- Active session IDs for each CLI
##### session_set_active
Set the active session for a specific CLI.
Parameters:
cli(string, required): CLI to set active session forsessionId(string, required): Session ID to activate (or null to clear)
##### session_get
Retrieve details for a specific session.
Parameters:
sessionId(string, required): Session ID to retrieve
##### session_delete
Delete a specific session.
Parameters:
sessionId(string, required): Session ID to delete
##### session_clear_all
Clear all sessions, optionally for a specific CLI.
Parameters:
cli(string, optional): Clear sessions for specific CLI only
#### Utility Tools
##### list_models
List available models for each CLI.
Parameters:
cli(string, optional): Specific CLI to list models for ("claude", "codex", "gemini", "grok", "mistral")
Response includes:
- Model names and descriptions
- Best use cases for each model
- CLI-specific information
defaultModelanddefaultModelSourcewhen a default is explicitly configuredmodelMetadatawith source/confidence (fallback,config,env,observed)aliasesandwarningswhen configured or when discovery degrades gracefully
The registry treats explicit configuration as authoritative. Bundled fallback models are low-confidence hints, and Gemini models observed in local session history are merged as low-confidence entries only; they do not become the default model.
Model registry environment overrides:
# Explicit defaults
CLAUDE_DEFAULT_MODEL=haiku
CODEX_DEFAULT_MODEL=<codex-model-id>
GEMINI_DEFAULT_MODEL=gemini-2.5-flash
# Additional models: comma/newline list, JSON array, or JSON object of model->description
GEMINI_MODELS='{"gemini-team-default":"Team-approved Gemini model"}'
# Aliases
GEMINI_MODEL_ALIASES='team=gemini-team-default'
LLM_GATEWAY_MODEL_ALIASES='codex.fast=gpt-5.3-codex-spark,gemini.fast=gemini-team-default'
# Deterministic config/discovery paths
CODEX_CONFIG_PATH=/path/to/config.toml
CLAUDE_SETTINGS_PATH=/path/to/settings.json
CLAUDE_SETTINGS_LOCAL_PATH=/path/to/settings.local.json
GEMINI_SETTINGS_PATH=/path/to/settings.json
GEMINI_HISTORY_ROOT=/path/to/.gemini/tmp
# Disable local model-history discovery
LLM_GATEWAY_DISABLE_MODEL_DISCOVERY=1##### provider_tool_capabilities
Report the provider tool and feature capability catalog. Use this before orchestrating provider-specific requests so callers can distinguish supported controls, provider-owned configuration, ignored parity fields, and unsupported inputs.
Parameters:
cli(string, optional): Provider filter ("claude","codex","gemini","grok","grok_api", or"mistral")includeSkills(boolean, defaulttrue): Include bounded local skill discoveryincludeProviderTools(boolean, defaulttrue): Include provider-native tools extracted from discovered skillsincludeUnsupported(boolean, defaulttrue): Include explicit unsupported/degraded input recordsincludePaths(boolean, defaultfalse): Include raw local filesystem paths in discovery outputrefresh(boolean, defaultfalse): Bypass the short-lived capability cache
The response schema is provider-tool-capabilities.v2. Capability discovery is read-only and bounded; raw local paths are redacted unless includePaths is explicitly true, and secret-bearing auth files are not read.
Equivalent MCP resources:
provider-tools://catalog: full provider catalogprovider-tools://claudeprovider-tools://codexprovider-tools://geminiprovider-tools://grokprovider-tools://grok_apiprovider-tools://mistral
doctor --json also emits a compact provider_capabilities block with the same schema version, per-provider request tool names, supported feature names, unsupported input names, config-surface counts, discovery counts, and resource URIs. This block is intended for setup assistants that need a concise capability summary without local skill bodies or raw paths.
##### cli_versions
Report installed CLI versions.
Parameters:
cli(string, optional): Specific CLI to inspect ("claude", "codex", "gemini", "grok", "mistral")
##### cli_upgrade
Plan or run an upgrade for one CLI.
Parameters:
cli(string, required): CLI to upgrade ("claude", "codex", "gemini", "grok", "mistral")target(string, optional): Package tag/version/target, default:latestdryRun(boolean, optional): Return the upgrade plan without running it, default:truetimeoutMs(number, optional): Upgrade timeout whendryRun=false
Upgrade strategies:
- Claude latest:
claude update - Claude explicit target:
claude install <target> - Codex latest:
codex update - Codex explicit target:
npm install -g @openai/codex@<target> - Gemini latest:
agy update(Antigravity self-update; explicit version targets are unsupported) - Grok latest:
grok update - Grok explicit target:
grok update --version <target> - Mistral (Vibe): dispatches to the detected installer (
pip/uv/brew); errors with guidance when none is detected (Vibe ships no self-update command)
Example dry run:
{
"cli": "gemini",
"target": "latest",
"dryRun": true
}Session Management
How It Works
- Automatic Session Tracking: By default, the gateway automatically tracks sessions for each CLI
- Active Sessions: Each CLI can have one active session that's used by default
- Persistent Storage: Sessions are stored in
~/.llm-cli-gateway/sessions.json - Context Reuse: Using sessions maintains conversation history and context
Session Workflow
// 1. Create a new session
await callTool("session_create", {
cli: "claude",
description: "Debugging session",
setAsActive: true,
});
// 2. Make requests (automatically uses active session)
await callTool("claude_request", {
prompt: "What's the bug in this code?",
// sessionId is automatically used
});
// 3. Continue the conversation
await callTool("claude_request", {
prompt: "Can you explain that fix in more detail?",
continueSession: true,
});
// 4. List all sessions
await callTool("session_list", { cli: "claude" });
// 5. Switch to a different session
await callTool("session_set_active", {
cli: "claude",
sessionId: "some-other-session-id",
});
// 6. Delete when done
await callTool("session_delete", {
sessionId: "session-id-to-delete",
});Configuration
