What is the Coldstart MCP server?

Most knowledge and memory work still happens through a UI a human drives. Coldstart MCP server moves it into the conversation instead. Codebase memory for AI agents: an AST index plus agent-written notes that self-stale.

The short version

Self-maintaining codebase knowledge for AI coding agents.

The tools it exposes

The server publishes 1 tool. What each one is for:

  • Upgrading — A version stamp in the keeper's lockfile makes the old background keeper shut down on the next lookup; a fresh one spawns from the new binary. No

Getting it running

@cstart/coldstart on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

How it compares

Plenty of knowledge and memory servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Coldstart's toolset — Upgrading — is a fair guide to whether it matches your workflow. It is maintained by AkashGoenka; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Coldstart to MCP-compatible AI assistants such as Claude and Cursor, exposing 1 tool (Upgrading) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Coldstart directly.
