Longhand MCP Server
Persistent local memory for Claude Code. Every tool call, every file edit, every thinking block from every Claude Code session - stored verbatim on your machine. Searchable, replayable, and recallable by fuzzy natural-language questions. Zero API calls. Zero summaries. Zero decisions made by an AI about what's worth remembering.
People connecting memory tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

Security posture
What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

license MIT - declared in the repository
pypi package longhand - check the name against the project README before installing (PyPI has no namespace ownership)
registry namespace io.github.Wynelson94 is GitHub-verified and matches the repo owner

06 · Longhand FAQ
What is Longhand?
Persistent local memory for Claude Code. Every tool call, every file edit, every thinking block from every Claude Code session - stored verbatim on your machine. Searchable, replayable, and recallable by fuzzy natural-language questions. Zero API calls. Zero summaries. Zero decisions made by an AI about what's worth remembering.
Is Longhand still maintained?
Yes - as of 2026-08-25, its last commit was 2026-08-13 and it shipped 10+ releases in the last 90 days. We re-verify nightly.
How do I install Longhand?
Run `uvx longhand`. The README does not document required environment variables for a basic install. You can also paste the ready-made client config above.
Does Longhand run locally?
Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
