memmesh-cli

A local command-line memory system that stores and searches an agent's information in a SQLite database, a small file-based database.

In plain words
What is it for?
Use it to install memory support for compatible AI coding tools, save preferences or project facts, search them, and check or migrate the local database.
Why use it?
It gives coding agents persistent project or user memory without an account, API key, or network connection.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

memmesh-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MemMesh CLI

The CLI drives the same Rust engine as the hosted platform, but fully local over SQLite — no account, no key, no network. It is also the recommended way to give any MCP-capable agent persistent memory.

Install (one command, multi-tool)

npx @thinkfleet/memmesh install        # or: memmesh install

This auto-detects your installed AI tools and, for each, writes the MCP server config and drops the teaching skill:

  • Claude Code (~/.claude.json + ~/.claude/skills/)
  • Cursor (~/.cursor/mcp.json)
  • Windsurf
  • Codex CLI

Useful flags: --dry-run (preview), --tool <name> (one tool only), --skill-only / --mcp-only, --force (overwrite existing config).

Verify wiring at any time:

memmesh doctor        # checks binary, MCP config, skill presence, hooks

Memory subcommands

memmesh save --type preference --scope user --content "prefers pnpm over npm"
memmesh get <id>
memmesh search --project myapp --query "database"        # substring/scoped search
memmesh list  --project myapp --limit 20
memmesh migrate                                          # run pending DB migrations

Run the MCP server

Most agents launch this for you via the config the installer wrote. To run it by hand (stdio JSON-RPC 2.0):

memmesh mcp

The server exposes 15 tools — see the memmesh skill for the full list and the observe/recall usage pattern. Highlights beyond basic CRUD: memory_predict, memory_build_context, memory_graph_reason, memory_query_graph, memory_prefetch_related, plus the client-LLM graph extraction pair (memory_extract_pending / memory_commit_extraction) — the engine never makes LLM calls; your agent's own model does the extraction.

Local vs hosted

Local (CLI + MCP) Hosted (SDK / Mesh Router)
Storage SQLite (~/.thinkfleet-memory/memory.db) Postgres, multi-tenant
API key not required mm-… key or Cognito JWT
Surface 15 MCP tools + CLI full TS SDK (memmesh-sdk)
Sync CRDT-style bi-temporal push to server (optional) authoritative

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

memmesh-cli is a skill published in the GitHub repository ThinkfleetAI/memmesh (440 stars, last pushed 7d ago), licensed Apache-2.0. It adds 164 tokens to every session and 906 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
