python3 scripts/gitmcp.py fetch-docs owner/repo

Search Documentation

Semantic search within repository documentation:

python3 scripts/gitmcp.py search-docs owner/repo "query"

Search Code

Search code using GitHub Search API (exact match):

python3 scripts/gitmcp.py search-code owner/repo "function_name"

Fetch Referenced URL

Fetch content from URLs mentioned in documentation:

python3 scripts/gitmcp.py fetch-url owner/repo "https://example.com/doc"

Direct Tool Call

Call any MCP tool directly:

python3 scripts/gitmcp.py call owner/repo tool_name '{"arg": "value"}'

Tool Names

Tool names are dynamically prefixed with the repo name (underscored):

  • karpathy/llm-councilfetch_llm_council_documentation
  • facebook/reactfetch_react_documentation
  • my-org/my-repofetch_my_repo_documentation

Available MCP Tools

For any repository, these tools are available:

  1. fetch_{repo}_documentation - Fetch entire documentation. Call first for general questions.
  2. search_{repo}_documentation - Semantic search within docs. Use for specific queries.
  3. search_{repo}_code - Search code via GitHub API (exact match). Returns matching files.
  4. fetch_generic_url_content - Fetch any URL referenced in docs, respecting robots.txt.

Workflow

  1. When given a GitHub repo, first fetch documentation to understand the project
  2. Use search-docs for specific questions about usage or features
  3. Use search-code to find implementations or specific functions
  4. Use fetch-url to retrieve external references mentioned in docs
