Mooring β Git & GitHub MCP Server
Mooring lines for your code β Git and GitHub operations for AI tools.
Mooring is an MCP server that gives AI assistants structured access to local Git repositories and the GitHub API. Local operations use GitPython (no subprocess calls). GitHub operations use the PyGithub library with token masking and rate limit handling built in.

Installation
# PyPI
pip install mooring-mcp
# Isolated install
pipx install mooring-mcp
Usage
Run the server directly:
mooring
Claude Code
claude mcp add mooring -- mooring
Claude Desktop
Add to your Claude Desktop configuration (claude_desktop_config.json):
{
"mcpServers": {
"mooring": {
"command": "mooring",
"env": {
"GITHUB_TOKEN": "your-github-personal-access-token"
}
}
}
}
The GITHUB_TOKEN environment variable is required for all GitHub tools (gh_*). Local Git tools work without it.
Security
- Path traversal protection β file paths are resolved and validated against the repository root before any operation
- Symlink escape detection β symlinks that resolve outside the repository are rejected
- Ref validation β Git refs are checked against a safe character pattern and verified to exist before use
- Token masking β error messages are scrubbed for GitHub token patterns (
ghp_*,gho_*,github_pat_*) before being returned - Rate limit handling β GitHub 403 responses are caught and surfaced as clear messages instead of raw exceptions
Development
git clone https://github.com/seayniclabs/mooring.git
