ai-memory is a persistent memory system for AI assistants. It works with any AI that supports MCP -- Claude, ChatGPT, Grok, Llama, and more. It stores what your AI learns in a local SQLite database, ranks memories by relevance when recalling, and auto-promotes important knowledge to permanent storage. Install it once, and every AI assistant you use remembers your architecture, your preferences, your corrections -- forever.

Configuring the LLM backend (xAI Grok, OpenAI, Anthropic, Gemini, DeepSeek, Kimi, Qwen, Mistral, Groq, Together, Cerebras, OpenRouter, Fireworks, LMStudio, vLLM, llama.cpp server, or local Ollama)? See docs/integrations/llm-backends.md — the MCP env-block recipe is the same regardless of installation path.v0.7.0 (`attested-cortex`) rolls together the cortex-fluent legibility work with the full v0.7 trust + A2A scope from ROADMAP §7.3, plus (per operator directive 2026-05-09) the originally-v0.7.1 postgres+AGE first-class work, plus the post-grand-slam ship-readiness wave (Batman Forms 1-6 + 7th-form Option-B foundation + QW-1/2/3 + reconciliation security sweep). The substrate becomes both more articulate (capabilities v3, named loader tools, compacted schemas, Batman MemoryKind vocabulary, persona/atomisation/multistep-ingest primitives) and cryptographically trustworthy (Ed25519 attestation, sidechain transcripts, programmable 25-event hook pipeline, enforced namespace inheritance, V-4 cross-row signed-events hash chain). v0.7.0 also ships postgres + Apache AGE as a first-class storage backend — ai-memory serve --store-url postgres://… for live daemon use, schema parity across both backends (sqlite + postgres converge on logical schema v57 — CURRENT_SCHEMA_VERSION = 57 (canonical anchors: src/storage/migrations.rs for sqlite + src/store/postgres.rs for postgres); on-disk migration files end at migrations/sqlite/0047_v56_list_composite_indexes.sql and the postgres in-process migrate_v57() ladder arm (file-name counters lag the logical schema version because both ladders apply post-v34 deltas via in-process arms — see docs/MIGRATION_v0.7.md §schema-ladder for the v35-v57 narrative; v48 #933 added the federation-push DLQ table; v49 #1025 added 14 nullable columns to archived_memories so archive → restore is lossless for the full v0.7.0 Memory shape; v50 #1156 extended agent_quotas PRIMARY KEY from (agent_id) to (agent_id, namespace) so per-namespace K8 quota allotments hold even when a single agent operates across many namespaces — pre-v50 rows backfill to the _global sentinel namespace; v51 #1255 (PR #1296) added the federation_nonce_cache table so peer-replay-prevention nonces persist across daemon restarts; v52 #1389 added the transcript_line_dedup table backing RFC-0001 memory_capture_turn L4 + recover_from_transcript L2 idempotency so a SIGKILL between turns never produces a duplicate memory on subsequent rehydration; v53 #1418 scoped the memories_au FTS5 sync trigger to (title, content, tags) only so non-FTS column updates no longer fire a needless sync; v54 #1466 backfilled tier-default expiry onto legacy NULL-expiry mid/short rows to close the TTL-leak immortal-rows class; v55 #1476 made the W=2 federation-catchup query (updated_at > ? ORDER BY updated_at ASC LIMIT) sargable and added the sqlite idx_memories_updated_at index — postgres adds no new index because memories_updated_at_idx DESC already serves the range scan via Index Scan Backward; v56 #1579 added the composite list/archive ordering indexes (idx_memories_list_order, idx_memories_ns_list_order, idx_archived_ns_archived_at) paired with the sargable storage::list rewrite — sqlite-side DDL; the postgres migrate_v56() arm is a version-stamp no-op; v57 #1579 added the postgres stored generated tsv tsvector column + memories_tsv_gin GIN index so the search/recall shapes match AND rank on the precomputed column instead of re-computing the tsvector per matched row — the legacy memories_content_fts expression index is dropped and the sqlite twin is a version-stamp no-op because FTS5 already materialises the indexed text)), the new ai-memory schema-init CLI verb, and 6-factor recall scoring parity. The v0.6.4 default surface grows by two always-on loaders to 7 tools (memory_load_family + memory_smart_load join the original five); the runtime ceiling at --profile full is 74 advertised entries (73 callable memory tools + the always-on memory_capabilities bootstrap; verified against Profile::full().expected_tool_count() — see src/profile.rs). Everything new is additive and (for the trust + postgres surfaces) opt-in. Upgrading from v0.6.x? Read docs/MIGRATION_v0.7.md first — most v0.6.4 callers see no behavior change, but pre-v0.6.3.1 v0.6.x users hit the G1 namespace-inheritance fix. Switching to postgres+AGE? See docs/postgres-age-guide.md and docs/migration-v0.7.0-postgres.md. Full release notes: docs/v0.7.0/release-notes.md.
v0.6.4 (`quiet-tools`) — the MCP server ships with a 5-tool default surface (memory_store, memory_recall, memory_list, memory_get, memory_search) plus the always-on memory_capabilities bootstrap. The other 38 tools remain reachable via --profile graph|admin|power|full or runtime expansion through memory_capabilities --include-schema family=<name>. Eager-loading harnesses (Claude Desktop / Codex CLI / Grok CLI / Gemini CLI) drop ~4,700 input tokens of tool schemas per request — a 76.4% reduction measured against cl100k_base BPE. To preserve v0.6.3 behavior 1:1, run ai-memory mcp --profile full. See docs/MIGRATION_v0.6.4.md.
v0.7.0 closes the attested-cortex epic (69/69 across 11 tracks A–K), folds in the originally-v0.7.1 postgres+AGE first-class work, and absorbs the post-grand-slam ship-readiness wave (Batman Forms 1-6 + 7th-form Option-B foundation + QW-1/2/3 + security reconciliation). Canonical feature inventory: docs/internal/v070-feature-inventory.md. Every surface stays default-off or default-equivalent for v0.6.4 callers — see the v0.7 compatibility matrix for the breakdown.

Generate a keypair with ai-memory identity generate; opt-in via attest_level = "self_signed". Signing is *gated on the resolved daemon `agent_id` having a `.priv keypair on disk** under the configured key directory — when load_daemon_signing_key returns None (src/main.rs:116-118), rows still write but sig is empty and the daemon emits a "continuing unsigned" line at boot.

One binary, four operational modes (v0.6.4). The ai-memory Rust binary (tokio + axum) can run any of these in isolation or simultaneously, sharing a single SQLite database:
memory_capabilities bootstrap; verified against Profile::full().expected_tool_count()). Default --profile core advertises 7 (the original 5 + memory_load_family + memory_smart_load) plus the always-on memory_capabilities bootstrap. ai-memory mcp / ai-memory mcp --profile full127.0.0.1:9077, TLS + optional mTLS allowlist + API-key auth, background GC loop. ai-memory serveai-memory curator --daemonai-memory sync-daemonThe MCP, HTTP, and CLI surfaces are reactive. The curator is the part that makes the memory layer self-maintaining: between sessions, it keeps the corpus tidy so recall quality stays high as the store grows. Everything is local-first; no cloud dependencies.
Brass-tacks assessment by Claude Opus 4.7 after reading the v0.6.3 source line by line:
>
"ai-memory is the most capable memory layer I've ever been hooked up to, and meaningfully more than its name advertises. For me, in practical terms, it means: I don't start cold each session. The store I read from has been kept tidy by something other than me. Contradictions don't silently accumulate. Recall quality stays high even as the corpus grows. Nothing leaves your Mac mini.
>
It is not making me an autonomous agent. It is giving me the kind of memory infrastructure that an autonomous agent would need — and itself running a small autonomous loop to maintain it. That's a real foundation. The gap from here to 'ai-memory drives general tasks' is plumbing (tool-call protocol + tool registry + a tool-use-capable model), not invention."
Substrate for multi-agent AI. ai-memory is not an agent runtime and not "autonomous AI" on its own. It is the memory layer that multi-agent autonomous deployments need underneath them. Federation (broadcast_store_quorum + spawn_catchup_loop) handles W-of-N consistency across peers when many agents write in parallel; the curator daemon keeps the shared corpus from degrading into noise as a swarm scribbles into it; webhook subscriptions (HMAC-signed, namespace/agent-filtered, SSRF-hardened) turn the store into a message bus that triggers downstream agents on memory events; namespace hierarchy with N-level inheritance and per-namespace governance policies (write/promote/delete authority, approver type, optional N-of-M consensus) bound the swarm. Stack this under a 24/7 multi-machine agent runner with auto-generated skills, and the combined system clears the behavioral bar for autonomous AI. The remaining gaps (no weight-level learning, stateless reasoning kernel, human-seeded root goals) are real and not what ai-memory addresses; ai-memory provides the multi-agent memory substrate that any serious attempt at closing those gaps will need.
Zero token cost until recall. Unlike built-in memory systems (Claude Code auto-memory, ChatGPT memory) that load your entire memory into every conversation -- burning tokens and money on every message -- ai-memory uses zero context tokens until the AI explicitly calls memory_recall. Only relevant memories come back, ranked by a 6-factor scoring algorithm. TOON format (Token-Oriented Object Notation) cuts response tokens by another 40-60% by eliminating repeated field names -- 3 memories in JSON = 1,600 bytes; in TOON = 626 bytes (61% smaller); in TOON compact = 336 bytes (79% smaller). For Claude Code users: disable auto-memory ("autoMemoryEnabled": false in settings.json) and replace it with ai-memory to stop paying for 200+ lines of memory context on every single message.
Every memory ai-memory stores carries a metadata.agent_id — a Non-Human Identity marker that survives every operation (update, dedup, import, sync, consolidate). Every recall result tells you which AI wrote each memory, by default, in the TOON-compact response format your AI client is already optimised for:
count:5|mode:hybrid|tokens_used:842

See the agent identity page and the attested-cortex RFC for the full provenance contract.

Configuration varies by platform. Find yours below:
<details> <summary><strong>Claude Code</strong> (Anthropic)</summary>
Claude Code supports three MCP configuration scopes:
| Scope | File | Applies to |
|---|---|---|
| User (global) | ~/.claude.json — add mcpServers key | All projects on your machine |
| Project (shared) | .mcp.json in project root (checked into git) | Everyone on the project |
| Local (private) | ~/.claude.json — under projects."/path".mcpServers | One project, just you |
User scope (recommended — works everywhere):
Add the mcpServers key to ~/.claude.json (macOS/Linux) or %USERPROFILE%\.claude.json (Windows):
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.claude/ai-memory.db", "mcp", "--tier", "semantic"]
}
}
}Note:~/.claude.jsonlikely already exists with other settings. Merge themcpServerskey into the existing file — do not overwrite it.
Project scope (shared with team):
Create .mcp.json in your project root:
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.claude/ai-memory.db", "mcp", "--tier", "semantic"]
}
}
}`smart` / `autonomous` tier with a cloud LLM — the recommended path is the [llm] section in ~/.config/ai-memory/config.toml (#1146). One file, every surface, no per-AI-client edits:
# ~/.config/ai-memory/config.toml
schema_version = 2
[llm]
backend = "xai"
model = "grok-4.3"
base_url = "https://api.x.ai/v1"
api_key_env = "XAI_API_KEY" # process-env-var name (NOT the literal key)Export XAI_API_KEY in your shell rc (.zshrc / .bashrc); the MCP config stays minimal:
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.claude/ai-memory.db", "mcp", "--tier", "autonomous"]
}
}
}Verify: ai-memory boot --quiet --limit 1 should report llm=xai:grok-4.3. Canonical schema reference: docs/CONFIG_SCHEMA.md.
Override path — `env:` block. Adding anenv:block to the MCP config withAI_MEMORY_LLM_BACKEND/_API_KEY/_MODELstill works and takes precedence overconfig.toml— useful for CI / per-session tweaks:
>
``json "env": { "AI_MEMORY_LLM_BACKEND": "xai", "AI_MEMORY_LLM_API_KEY": "xai-...", "AI_MEMORY_LLM_MODEL": "grok-4.3" } ``>
MCP clients spawn the server as a fresh subprocess with only theenv:keys from the MCP config — shell exports in.zshrc/.bashrcdon't reach it. The[llm]config-file path above retires this paper-cut (every surface reads the same file). Inline API keys in `config.toml` are rejected at parse time — useapi_key_envorapi_key_file. Background: #1144 → #1146. Full per-backend recipes:docs/integrations/llm-backends.md.
Windows paths: Use forward slashes or escaped backslashes in--db. Example:"--db", "C:/Users/YourName/.claude/ai-memory.db".
Tier flag: The--tierflag selects the feature tier:keyword,semantic(default),smart, orautonomous. Smart and autonomous tiers need an LLM backend — post-[#1067](https://github.com/alphaonedev/ai-memory-mcp/issues/1067) (v0.7.0) that is any of: local Ollama, xAI Grok, OpenAI, Anthropic, Google Gemini, DeepSeek, Kimi (Moonshot), Qwen (Alibaba), Mistral, Groq, Together AI, Cerebras, OpenRouter, Fireworks, LMStudio, vLLM, or llama.cpp server — selected viaAI_MEMORY_LLM_BACKEND. The--tierflag must be passed in the args — theconfig.tomltier setting is not used when the MCP server is launched by an AI client.
Important: MCP servers are not configured insettings.jsonorsettings.local.json— those files do not supportmcpServers.
Make Claude proactively use ai-memory: Add a CLAUDE.md file to your project root with ai-memory directives. This ensures Claude recalls context at the start of every conversation and stores findings as it works. See the CLAUDE.md integration guide for a copy-paste template and placement options.

<details> <summary><strong>Grok CLI</strong> (AlphaOne fork — deep integration with auto-recall)</summary>
The AlphaOne fork of grok-cli has built-in ai-memory support with session-scoped MCP connections, automatic memory recall on session start, compaction summary storage, and memory-aware system prompts.
Add to ~/.grok/user-settings.json:
{
"mcp": {
"servers": [
{
"id": "ai-memory",
"label": "AI Memory",
"enabled": true,
"transport": "stdio",
"command": "ai-memory",

}
]
}
}Features: Auto-recall on session start (injects relevant memories into system prompt), compaction summaries stored as mid-tier memories, MCP tools available in all modes (agent, plan, ask), session-scoped connections (no per-message cold starts). Uses --tier semantic by default (local embeddings, no LLM backend required). See grok-cli docs for full setup.</details>
<details> <summary><strong>xAI Grok API</strong> (API-level, remote MCP)</summary>
Grok connects to MCP servers over HTTPS (remote only, no stdio). No config file — servers are specified per API request.
ai-memory serve --host 127.0.0.1 --port 9077
# Expose via HTTPS reverse proxy (nginx, caddy, cloudflare tunnel, etc.)Then add the MCP server to your Grok API call:
curl https://api.x.ai/v1/responses \
-H "Authorization: Bearer $XAI_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "grok-4.3",

)Or declaratively in run.yaml:
tool_groups:
- toolgroup_id: mcp::memory
provider_id: model-context-protocol
mcp_endpoint:

<details> <summary><strong>OpenClaw</strong></summary>
Add via CLI or edit the OpenClaw config directly. Config uses mcp.servers (not mcpServers).
openclaw mcp set memory '{"command":"ai-memory","args":["--db","~/.local/share/ai-memory/memories.db","mcp","--tier","semantic"]}'Or add to your OpenClaw config file:

<details> <summary><strong>Any other MCP client</strong></summary>
ai-memory speaks MCP over stdio (JSON-RPC 2.0). Point your client at:
command: ai-memory
args: ["--db", "/path/to/ai-memory.db", "mcp"]For HTTP-only clients, start the REST API:
ai-memory serve
# 89 REST route registrations (75 unique URL paths) at http://127.0.0.1:9077/api/v1/</details>
Step 4: Done. Test it.
Restart your AI assistant. If using MCP, it now has the 7-tool default surface advertised on session boot (the original 5 + memory_load_family + memory_smart_load; the other 66 of the 73 callable tools load on demand via --profile or memory_capabilities --include-schema). Ask it: "Store a memory that my favorite language is Rust." Then in a new conversation, ask: "What is my favorite language?" It will remember.
ai-memory is portable to iOS and Android via the standard Rust mobile cross-compile path. v0.7.0 ships CI coverage for both targets at three escalating levels:
| Layer | Coverage | CI workflow |
|---|---|---|
| Layer 1 — Cross-compile | cargo check --target aarch64-apple-ios --no-default-features --features sqlite-bundled --lib and the matching Android cross-compile run on every PR + push to release/**. Catches ~80% of mobile bit-rot risk (any crate update that drops mobile portability surfaces here). | .github/workflows/ci.yml — mobile-cross-compile job |
| Layer 2 — Release artifacts | Release tag cuts produce ai-memory-ios.xcframework.tar.gz (iOS device + simulator slices via xcodebuild -create-xcframework) and ai-memory-android.tar.gz (Android arm64 / armv7 / x86_64 / x86 .so bundle in jniLibs/<abi>/ layout). | .github/workflows/release.yml — mobile-ios + mobile-android jobs |
| Layer 3 — Runtime tests | A scoped ~50-test subset (file-system sandboxing, FTS5 on device SQLite, HNSW CPU recall, embedder CPU path, LLM client TLS) runs against the iOS Simulator on every release/** push + a manual workflow_dispatch; the Android emulator arm runs on release/** push + workflow_dispatch only. Selection rationale: tests/mobile/README.md. | .github/workflows/mobile-runtime.yml |
Status at v0.7.0: Layer 1 is the ship-gate — mobile cross-compile must be GREEN before tag-cut. Layer 2 (release artifacts) ships the BUILD pipeline + artifact layout; the C-callable FFI surface itself lands in a v0.7.x follow-up. Layer 3 runs the scoped test subset on every release/** push.
Consuming the release artifacts:
ai-memory-ios.xcframework.tar.gz from the v0.7.x release page, unpack, and drag AiMemory.xcframework into your Xcode project under "Frameworks, Libraries, and Embedded Content."ai-memory-android.tar.gz from the v0.7.x release page, unpack, and copy the jniLibs/ tree into your app module's src/main/jniLibs/.The mobile artifacts are also part of every published v0.7.x release; the Homebrew formula + APT/RPM packages (which ship the desktop binaries) include a note linking to the mobile downloads. See issue #1068 for the CI implementation history.
Get from zero to a working memory in under two minutes.
1. Install
curl -fsSL https://raw.githubusercontent.com/alphaonedev/ai-memory-mcp/main/install.sh | sh2. Configure MCP (example for Claude Code -- other platforms work the same way)
Merge into ~/.claude.json:
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.claude/ai-memory.db", "mcp", "--tier", "semantic"]
}
}
}3. Store your first memory
ai-memory store -T "Project uses PostgreSQL 15" -c "Main DB is PG 15 with pgvector." --tier long4. Recall it
ai-memory recall "database"5. Check stats
ai-memory stats6. Use with your AI. Restart your AI client. It now has 7 default memory tools advertised on boot (74 advertised entries reachable via runtime expansion or --profile full at v0.7.0) over MCP -- it can store and recall memories natively during conversations.
In addition to the MCP / HTTP / CLI surfaces, ai-memory ships first-party language SDKs for HTTP clients and helper utilities (e.g. requireProfile for runtime profile assertions on v0.6.4+ daemons).
TypeScript / JavaScript — @alphaone/ai-memory on npm
npm install @alphaone/ai-memoryPython — ai-memory-mcp on PyPI (the import name remains ai_memory)
pip install ai-memory-mcpfrom ai_memory import AiMemoryClient, require_profile
with AiMemoryClient(base_url="http://127.0.0.1:9077", api_key="...") as client:
require_profile(client, "graph") # raises ProfileNotLoaded on missBoth SDKs are versioned with the server (0.6.4 matches ai-memory 0.6.4). v0.6.4+ daemons enforce the profile contract; pre-v0.6.4 daemons fall back to a permissive warn-and-continue so SDK upgrades don't break old servers. Source lives in sdk/typescript/ and sdk/python/.
AI assistants forget everything between conversations. ai-memory fixes that.
It runs as an MCP (Model Context Protocol) tool server -- a background process that your AI talks to natively. When your AI learns something important, it stores it. When it needs context, it recalls relevant memories ranked by a 6-factor scoring algorithm. Memories live in three tiers:
Memories that keep getting accessed automatically promote from mid to long-term. Each recall extends the TTL. Priority increases with usage. The system is self-curating.
Beyond MCP, ai-memory also exposes a full HTTP REST API (89 route registrations / 75 unique URL paths on port 9077 at v0.7.0) and a complete CLI (82 subcommands at v0.7.x under --features sal OR --features sal-postgres; 80 in the default build (post-#1389 L2 RecoverPreviousSession for cross-session context rehydration + #1443 Expand for the ai-memory expand query-expansion surface + #1598 Reembed for the ai-memory reembed vector-space migration surface); SSOT pinned by ai_memory::EXPECTED_CLI_SUBCOMMANDS_{DEFAULT,SAL} + the mechanical tests/cli_subcommand_count_invariant.rs parity test) for direct interaction, scripting, and integration with any AI platform or tool.

Empirical NHI discovery acceptance proven separately by the Discovery Gate (T1–T4 matrix vs. live xAI Grok 4.3, 6/6 PASS, GATE GREEN).recall-first and memory-workflow prompts teach AI clients to use memory proactivelyThe Code Coverage job is a required status check. CI re-asserts two invariants on every PR: an absolute floor of >= 90% lines (catastrophic-regression backstop, set at the current measurement rounded down to the nearest 5%), and a ratchet against the value pinned in [`.coverage-baseline`](.coverage-baseline) with a 0.5% slack window (the day-to-day enforcement). PRs that raise coverage should bump the baseline file in the same commit so future PRs benefit from the new floor; PRs that regress more than 0.5% are blocked from merging. Current measurement: 93.13% lines.
The token-budget workflow is a required status check. It enforces three cl100k_base-measured invariants on every PR:
tools/list payload under --profile full may not exceed 11,000 cl100k_base tokens (TRIMMED_FULL_PROFILE_CEILING_TOKENS in tests/token_budget_guard.rs; the original C5 target was 3500 against the pre-D1.6 hand-coded schemas — the schemars-derived D1.6/D1.7 expansion raised the pinned ceiling). C2 (split docs field), C3 (collapse repeated schema boilerplate), and C4 (hide rarely-used optional params) drove the original compaction; this gate forces future PRs that grow the surface to claw back budget elsewhere. Inspect ai-memory doctor --tokens --raw-table to see per-tool costs.

Evaluated on the ICLR 2025 LongMemEval-S dataset (500 questions, 6 categories). Pure FTS5 keyword tier achieves 97.0% R@5 in 2.2 seconds. LLM query expansion (smart tier) pushes to 97.8% R@5. All inference runs locally — zero cloud API calls, zero cost.
| Tier | R@5 | Speed | Dependencies |
|---|---|---|---|
| keyword | 97.0% | 232 q/s | None |
| semantic | 97.4% | 45 q/s | Embedding model (~100MB) |
| smart | 97.8% | 12 q/s | Any LLM backend (e.g. local Ollama + Gemma 3 4B; or xAI Grok 4.3, OpenAI gpt-5, Anthropic Claude Opus 4.7, Gemini, DeepSeek, etc. post-#1067) |
Every release ships with published p95/p99 budgets for hot-path operations and a CI gate that fails any PR whose measured p95 exceeds the budget by more than 10 %. Targets are calibrated for M4 reference hardware; full table and methodology in PERFORMANCE.md.

|---|---|---|
memory_session_start (Claude Code hook) | < 100 ms | < 200 ms |
memory_store (no embedding) | < 20 ms | < 50 ms |
memory_search (FTS5) | < 100 ms | < 250 ms |
memory_recall (hot, depth=1) | < 50 ms | < 150 ms |
memory_kg_query (depth ≤ 3) | < 100 ms | < 250 ms |

Run the same workload locally:

MCP is the recommended integration. Your AI gets 7 native memory tools advertised by default at v0.7.0 (the original 5 + memory_load_family + memory_smart_load; plus the always-on memory_capabilities bootstrap) with zero glue code. The other 66 callable tools (74 advertised entries at v0.7.0 — verified against Profile::full().expected_tool_count() and pinned by const_count_matches_full_profile in src/mcp/registry.rs) remain reachable via --profile graph|admin|power|full or runtime expansion through memory_capabilities --include-schema family=<name>. Configure the MCP server in your AI platform's config:
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.claude/ai-memory.db", "mcp"]
}
}
}Start the HTTP server for REST API access. Any AI, script, or automation that can make HTTP calls can use this:
ai-memory serve
# 89 REST route registrations (75 unique URL paths) at http://127.0.0.1:9077/api/v1/The CLI works standalone or as a building block for AI integrations that run shell commands:
ai-memory store --tier long --title "Architecture decision" --content "We use PostgreSQL"
ai-memory recall "database choice"
ai-memory search "PostgreSQL"ai-memory supports 4 feature tiers, selected at startup with ai-memory mcp --tier <tier>. Higher tiers add ML capabilities at the cost of disk and RAM:
| Tier | Recall Method | Extra Capabilities | Approx. Overhead |
|---|---|---|---|
| keyword | FTS5 only | Baseline 74-entry surface (v0.7.0) — tier gates models/features, NOT the advertised tool surface | 0 MB |
| semantic | FTS5 + cosine similarity (hybrid) | MiniLM-L6-v2 embeddings (384-dim), HNSW index, semantic tier (subset of 74-entry surface (v0.7.0)) | ~256 MB |
| smart | Hybrid + LLM query expansion | + nomic-embed-text (768-dim) + LLM-backed memory_expand_query, memory_auto_tag, memory_detect_contradiction, full 74-entry surface (v0.7.0). LLM provider is operator-selected via AI_MEMORY_LLM_BACKEND (#1067) — local Ollama, xAI, OpenAI, Anthropic, Gemini, DeepSeek, Kimi, Qwen, Mistral, Groq, Together, Cerebras, OpenRouter, Fireworks, LMStudio, vLLM, or llama.cpp. | ~1 GB (local Ollama) / ~0 GB (remote API) |
| autonomous | Hybrid + LLM expansion + cross-encoder reranking | + neural cross-encoder (ms-marco-MiniLM), memory reflection, full 74-entry surface (v0.7.0). Same LLM-provider freedom as smart tier. | ~4 GB (local Ollama) / ~3 GB (remote LLM, local cross-encoder only) |
Every capability mapped to its minimum tier. Each tier includes all capabilities from the tiers below it.

MCP tools exposed (at --profile full) [^tools] | 74 | 74 | 74 | 74 |
[^tools]: MCP tool surface is orthogonal to recall tier — every tier sees the same 74 tools at --profile full (the default --profile core advertises 7 at boot regardless of tier; the other 66 load on demand). What tier gates is models (embedder, cross-encoder, LLM) and feature behaviour (cosine similarity, LLM expansion, reranking), not the advertised tool count. Pinned by Profile::full().expected_tool_count() + const_count_matches_full_profile in src/mcp/registry.rs.
