Overview

AI-generated overview

A local read-only MCP server that lets an assistant search and retrieve source code across a configured list of GitHub repositories.

What you can do
Search and retrieve source code across the GitHub repositories you configure, read-only. Refresh repository caches on demand, subject to a minimum interval between refreshes. Work against private repositories when a GitHub token is supplied. Keep caches, indexes and locks in a writable state directory on the local machine.
When to use it
Useful when you want an assistant to answer questions about code spread over several GitHub repositories, such as finding where something is defined or how a project is organized, without giving it write access.
Requirements
Runs as a local process (container image, stdio transport). Requires PROJECT_BRAIN_REPO_LIST, a comma-separated list of owner/repo slugs or a path to a file with one slug per line, and PROJECT_BRAIN_STATE_DIR, a writable directory for caches, indexes and locks. Network access to GitHub is needed. PB_GITHUB_TOKEN is optional and only for private repositories. PB_FETCH_TTL optionally sets the minimum interval between refreshes.
Before you install
PB_GITHUB_TOKEN is a secret; a token with access to private repositories should be scoped as narrowly as possible. The server is described as read-only, but it writes caches, indexes and locks into PROJECT_BRAIN_STATE_DIR, so point that at a directory you are comfortable having modified. Repository content is fetched from GitHub over the network.

Installation

In SourceWeft

  1. Open Project Brain in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
