How do I install the lema mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `LEMA_MCP_MODE`, `LEMA_PUBLIC_REPO`, `LEMA_API_URL`, `LEMA_API_TOKEN`, `LEMA_WORKSPACE_ID`, `GITHUB_TOKEN` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

Cited 'why was this decided?' answers for your repo and for React, Kubernetes, and Rust.

What you get

A local MCP server. No account, no database, no network for your own repo — install it in 30 seconds and ask why a project decided something, or whether the approach you're about to take was already rejected.

Abstain ≠ approval. — Silence is reported as silence. lema would rather say
Cited, summarized — not quoted. — Answers are grounded in recorded decisions and
Local-first. — Capture and enforcement run entirely on your machine, in a file
No fabricated graph. — A cold import writes no decision→decision edges and no
