index_repository
Index a GitHub repository to analyze its codebase. This must be done before asking questions about the repository.
LABSCO SUMMARY
Reading an unfamiliar codebase without cloning it first.
index_repository does the work up front and query_repository answers against it, so evaluating a dependency starts with a question rather than a checkout and a grep. Because each question carries conversation_history, the second one builds on the first instead of arriving cold.
What it is
Two tools in sequence: index a GitHub repository from its URL, then ask questions about that codebase and get AI answers back.
What you get
- A GitHub repository indexed from its URL, which the question tool requires first
- Questions answered about an indexed repository, with conversation_history passed in so a follow-up does not restate the last one
Requirements
uv on your PATH, which resolves the Python runtime through UV_PYTHON, and the URL of the repository. Indexing has to run before the first question.
Setup effort
One command — pip install github-chat-mcp
USE CASES
01
Sizing up a dependency before you adopt it
Index the repository from its URL, then ask the questions you would otherwise answer by cloning and grepping — what it depends on, how it handles the case you care about.
02
Following up on an answer without starting over
Ask the next question against the repository already indexed, passing the conversation history so the follow-up does not have to restate what was just established.
2 tools
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
query_repository
Ask questions about a GitHub repository and receive detailed AI responses. The repository must be indexed first.
