<details> <summary><b>Copy-paste setup prompt</b></summary>
Install and configure Servonaut, a TUI for managing servers (AWS EC2, OVHcloud, Hetzner Cloud, and custom SSH servers).
1. Install with all optional features: `pipx install 'servonaut[all]'`
(bundles the MCP server + OVH/Hetzner SDKs + keyring; AI log analysis needs no extra. Use plain `pipx install servonaut` for a minimal install.)
2. Run `servonaut` once to generate ~/.servonaut/config.json
3. (Optional) If I have a Servonaut account, run `servonaut login` to unlock the hosted features: Servonaut AI (chat with my fleet, no local API key), config sync across machines, Memory Sync, and proactive monitoring (Findings). Servonaut works fully offline against my own credentials if I skip this.
4. Read ~/.servonaut/config.json and help me configure:
- AWS regions to scan (default scans all, set `regions` array to limit)
- Default SSH username (`default_username`, default "ec2-user")
- Cache TTL (`cache_ttl_seconds`, default 3600)
- Terminal emulator if not auto-detected (`terminal_emulator`)
5. If I use bastion/jump hosts, help me set up `connection_profiles` and `connection_rules`
6. If I have non-AWS servers, help me add them to `custom_servers`
7. If I use OVHcloud or Hetzner Cloud, help me add the API credentials so those instances merge into the fleet
8. For AI log analysis or chat with my own model (instead of Servonaut AI), help me configure `ai_provider` (openai/anthropic/gemini/ollama)
- Each provider has its own key field (`openai_api_key`, `anthropic_api_key`, `gemini_api_key`, `ollama_api_key`); local Ollama needs none
- Key fields support `$ENV_VAR` and `file:~/.secrets/key` syntax so secrets stay out of the config file
9. Install the MCP server into my coding agent: `servonaut --mcp-install claude` (or `cursor`, `windsurf`, `opencode`, `vscode`, `codex`, `agy`, `gemini`, `all`)
10. (Optional) To let AI agents/teammates reach this machine over the relay — and to run proactive Findings scans — start it with `servonaut connect`
After setup, launch with `servonaut` and walk me through the key features, including the Findings inbox if I enabled the hosted features.</details>

All configuration lives in ~/.servonaut/config.json, created automatically on first run.
See Configuration Guide for the full reference including connection profiles, custom servers, scan rules, and match conditions.
SSH keepalives: all connections send keepalives by default so long or idle agent-driven sessions don't get dropped. Tune globally via the ssh block in config.json (server_alive_interval, server_alive_count_max, tcp_keepalive, connect_timeout).
Legacy / special-case SSH hosts: connection profiles and custom servers both accept an extra_ssh_options array that appends arbitrary -o KEY=VALUE flags per host — use it to talk to ancient OpenSSH boxes (HostKeyAlgorithms=+ssh-rsa), override keepalives, or set connect timeouts without weakening your global SSH defaults. See Per-host SSH tuning.
Secrets: API keys in config.json support $ENV_VAR and file:~/.secrets/key syntax so the config file stays secret-free. You can also create ~/.secrets/servonaut.env with KEY=value pairs — loaded automatically on startup.

AI log analysis (OpenAI, Anthropic, Gemini, Ollama) needs no extra install — httpx ships as a base dependency.
This section is for wiring up AI agents (Claude Code, Cursor, Windsurf, …) — not day-to-day interactive use. If you're a human operating your fleet, the TUI above is the recommended interface.
Servonaut includes an integrated MCP server that exposes tools to AI agents like Claude Code:
# Auto-install into a coding agent
servonaut --mcp-install claude # Claude Code
servonaut --mcp-install cursor # Cursor
servonaut --mcp-install windsurf # Windsurf
servonaut --mcp-install opencode # OpenCode
servonaut --mcp-install vscode # VS Code Copilot
servonaut --mcp-install codex # Codex CLI
servonaut --mcp-install agy # Antigravity CLI
servonaut --mcp-install gemini # Gemini CLI
servonaut --mcp-install all # All of the above
# Run MCP server manually (stdio transport)
servonaut --mcpRe-running an installer updates only Servonaut's launch command and required environment forwarding. Other MCP servers and user-owned settings such as timeouts, trust, tool filters, and custom environment entries are preserved. Secret values are never copied into agent configuration: supported clients use references, variable-name allowlists, or inherited environment to supply SSH/Bitwarden state, AWS credentials, Servonaut endpoints, and $ENV_VAR references found in the local Servonaut config. Invalid agent JSON is refused instead of overwritten, and config writes are atomic without replacing symlinked dotfiles.
SSH-backed MCP tools first use the configured local or vault key. If that key cannot authenticate and SSH_AUTH_SOCK was forwarded, Servonaut retries once using the agent without forcing the configured identity. Authentication failures are returned and audited as failures, never as successful tool calls.
#### Agent-only / headless install
You don't need the TUI to use Servonaut as an agent toolbox. The MCP server runs fully headless — servonaut --mcp never loads the terminal UI (this is enforced by a regression test), so you can install it on a server or CI box purely as an MCP backend for your coding agent:
pipx install 'servonaut[mcp]'
servonaut --mcp-install claude # or cursor, windsurf, opencode, vscode, codex, agy, gemini, allConfigure credentials and servers the same way as a TUI install ( ~/.servonaut/config.json, $ENV_VAR / file: secret syntax — see Configuration Guide). For Servonaut Cloud features (relay, config sync, hosted AI), servonaut login runs the device-flow sign-in fully headless — approve from a browser on any device. Everything an agent does goes through the same guard levels and is logged to ~/.servonaut/mcp_audit.jsonl.
SSH keys from Bitwarden (no keys on the box). If your instances have a Bitwarden SSH ref saved, the SSH-backed tools (run_command, get_logs, transfer_file, …) resolve the private key from your vault at connect time instead of needing it in ~/.ssh — so an agent on a fresh server or CI box can connect with no local keys at all. Because a headless process can't prompt for your master password, unlock the vault once and export the session into the environment the MCP server (or servonaut connect) runs in:
export BW_SESSION=$(bw unlock --raw) # unlock once; stays valid until you `bw lock` or the shell exits
servonaut --mcp # child inherits BW_SESSIONThe key is written to a private, 0600 temporary file only for the duration of each command and deleted immediately after. If the vault is locked or bw isn't installed, the tools fall back to local keys — a working local setup is never affected.

The tool list is filtered to what's actually usable: OVH and Hetzner tools appear only when those providers are configured, the ip_ban_* tools only when at least one IP-ban target is defined, and the *_server_memory* tools only when the memory subsystem is enabled. CloudWatch/CloudTrail and the core instance tools are always available (AWS is the base provider).
cloudwatch_top_ips parses WAF/ALB structured logs to rank client IPs with allowed/blocked counts — pair it with cloudtrail_lookup_events to corroborate, then ip_ban_set to block via WAF, a security group, or a NACL.whoami returns session metadata — the OAuth bearer is never exposed.api_request lets an agent make authenticated REST calls against servonaut.dev with automatic 401 refresh and a CLI-side rate limit (30/min). The bearer stays on the CLI.mcp_tool_call wraps a JSON-RPC 2.0 tools/call envelope against the hosted MCP at mcp.servonaut.dev — used for premium tools when your plan includes them.get_server_memory(id) returns the cached fact snapshot — agents call this BEFORE any SSH round-trip so they answer most OS / runtime / service questions without run_command. Pass format='context_block' to get back a <CONTEXT> envelope for direct prompt injection.Guard levels: readonly (list/status/introspection only — includes CloudWatch/CloudTrail and ip_ban_list_* queries), standard (read + safe commands + authenticated REST + power management — start / stop / reboot / shutdown + S3 download), dangerous (everything, including create_server / delete_server / transfer_file / ip_ban_set / aws_terminate_instance / aws_run_instances / S3 mutations (s3_create_bucket, s3_delete_bucket, s3_upload_object, s3_delete_object, s3_copy_object, s3_move_object, s3_generate_presigned_url)). Dangerous shell commands (rm -rf, shutdown, reboot, etc.) are always blocked regardless of guard level. Mutating tools carry an explicit "confirm with the user before calling" cue in their descriptions; the top-level MCP instructions document the three-step protocol (summarise → state args → wait for affirmative reply). All operations are logged to ~/.servonaut/mcp_audit.jsonl.
Optional — Servonaut works fully offline against your own AWS / OVH credentials. Signing in at servonaut.dev unlocks:

detection. Open the ☁ Memory Sync sidebar entry, click Unlock Memory Sync, and enter a passphrase. The same screen handles first-time enrolment AND post-restart unlock — your private key is wrapped with the passphrase locally, so the server never sees it. After unlock, click Sync now to push every cached server's memory modules as encrypted envelopes, or flip on auto-sync to drain the queue in the background so the server-side copy (and weekly digests) stay current. Unlock survives restarts: tick Remember on this device to silently re-unlock from your OS keychain on the next launch (re-prompted after 30 days, or Forget on this device to clear it). If you decline, Memory Sync stays dormant until you next open a memory section. Per-feature settings (digest cadence, Mercure push, AI consent) live at the bottom of the Settings panel and are stored on your servonaut.dev account.
Sign in from the TUI's Account / Login screen. After a successful device-flow authentication, the TUI auto-starts an in-process relay listener and the sidebar indicator flips to ● connected.
The listener is tied to the TUI window — closing the TUI drops the connection after ~60 s. For always-on reachability (CI runners, headless boxes), use servonaut connect --bg instead; the CLI and TUI cooperate over ~/.servonaut/relay.lock so they can't run at the same time. The TUI shows external listener (PID N) when a --bg listener is holding the connection.
servonaut connect # Foreground relay (Ctrl+C to stop)
servonaut connect --bg # Detach; writes ~/.servonaut/relay.pid
servonaut connect --status # Local + backend view with divergence warning
servonaut connect --stop # SIGTERM the background listener
servonaut connect --reconnect # Heal a stale SSE socket (stop+start)
servonaut connect --force-bg # Take over from a TUI's in-process listenerSee CLI Reference → servonaut connect for full flags.
Tokens are stored at ~/.servonaut/auth.json with mode 0600, written atomically via tmp + os.replace(). If an older build left the file world-readable, the next run auto-fixes it.
Server-side detectors scan your fleet for problems and post each one as a triageable finding card: severity, description, evidence, and remediation options. Detection runs in the Servonaut cloud; this client only runs read-only probes over your relay connection and renders the results — nothing is analysed or decided locally.

Centralise SSH keys + other named secrets behind a pluggable provider backend. Day-to-day this is invisible: once configured, SSH key resolution checks your provider automatically on every connect — you keep clicking SSH in the TUI and it just works. The commands below are one-time setup. MVP supports two backends:
~/.servonaut/secrets.json(mode 0600, atomic write, same trust model as auth.json). Always available on Solo and Teams plans.
Secrets Manager project. Team admin configures the project from https://servonaut.dev/account/teams/<slug>/secrets; CLI fetches the metadata and reads/writes through the local bws binary using your own access token. The token never leaves your machine — servonaut.dev only stores the project ID and the name of the env var holding the token.
To use Bitwarden as your team's backend:
# 1. Install the bws CLI (one-time)
servonaut secrets install bws # macOS: brew · Linux: cargo
# Windows / other → prints upstream install URL.
# 2. Mint a BWS access token (https://bitwarden.com/help/personal-access-tokens/)
# and export it
export BWS_ACCESS_TOKEN=<your-token>
# 3. Verify wiring
servonaut secrets status # your plan and where secrets are kept (--json for scripts)
# That's it — SSH key resolution now checks Bitwarden first, ~/.ssh as
# fallback. Push a key into BWS with `bws secret create`:
bws secret create "$(basename ~/.ssh/prod-server)" \
"$(cat ~/.ssh/prod-server)" \
--project-id <project-uuid-from-status>Key resolution order on every SSH connect:
~/.ssh discovery (existing patterns + fuzzy match).config.json::instance_keys[<id>] orconfig.default_key.
Free-tier users get the legacy ~/.ssh-only flow with zero behaviour change. Provider-supplied keys land in ~/.servonaut/keys/<name> at mode 0600.
Threat-model + design notes are pinned in the codebase via inline docstrings on services/secret_provider.py, services/bitwarden_provider.py, and services/secret_provider_resolver.py.
The same secret store also backs a database credential vault: scan a server for the DB credentials its apps already use — .env / DATABASE_URL (including DATABASE_URL_PROD / _STAGING variants), wp-config.php, configuration.php, Magento env.php, and docker-compose environment: blocks, with a read-only sudo -n fallback so root-owned files and containerized stacks are covered. Store the password under a per-site label and the db_processlist / db_top_queries tools resolve it by name — the password never lands in your config or in an AI agent's context.

auth.json | OAuth tokens for servonaut.dev, mode 0600, atomic writes |
secrets.json | Local secret store, mode 0600 (the default secrets backend) |
bw_ssh_refs.json | Saved Bitwarden SSH key references: item IDs only, never key material |
sync_key_probe.json | Check value that confirms your config-sync passphrase; holds neither the passphrase nor the key |
ip_ban_audit.json | IP ban audit trail |
mcp_audit.jsonl | MCP server audit trail |
aws_audit.jsonl, hetzner_audit.jsonl, ovh_audit.json | Audit trails of server lifecycle actions (create, start, stop, delete, …) per provider |
audit_queue.json | Team audit events waiting to be sent to servonaut.dev |
team_policy.json | The last verified agent rules of each of your teams, mode 0600, checked again whenever they are read (see Team agent rules) |
memory/ | Server-memory store: <provider>/<instance_id>/<module>.json per probed server, plus index.json |
memory/sync_queue.jsonl | Pre-encryption envelopes waiting to be pushed to servonaut.dev. Replayed on next bootstrap; deleted after a successful drain. Only present while Memory Sync has unsent work. |
memory/keys.json | Memory Sync keypair; the private key is stored encrypted with your passphrase |
memory_scan_state.json | When the background fleet memory scan last ran |
exports/ | Signed server-memory exports |
transfers/ | Local side of relay file transfers: the relay reads and writes local files only here |
voice_models/ | Downloaded voice models (the batch speech model uses the Hugging Face cache instead) |
relay.pid | Background servonaut connect --bg PID (when running) |
relay.lock | Advisory flock shared between the TUI's in-process listener and --bg, carries {pid, mode, acquired_at} |
relay-control.json | How to reach the TUI's relay listener, so servonaut connect --force-bg can take it over |
logs/servonaut.log | Application log, rotated at 2 MB with 5 older files kept |
logs/relay.log | Relay lifecycle events (one JSON line per event, secrets redacted) |
logs/native_stderr.log | Messages that native libraries (audio, speech) print directly, kept out of the TUI |
logs/servonaut_*.sh | Temporary wrapper scripts for SSH sessions opened in a new terminal window |
Logs are always written to ~/.servonaut/logs/servonaut.log. Use --debug for verbose stderr output.
When SSH fails, the terminal window stays open showing the error and exit code.
