Connects Claude to Codecov's API for querying test coverage data across repositories, commits, and pull requests. Exposes five tools: get file level line by line coverage, commit coverage stats, repo wide metrics, PR coverage deltas, and branch to branch comparison. Works with both codecov.io and self hosted instances through configurable base URLs. Requires a Codecov API token, not an upload token. Useful when you want Claude to analyze coverage trends, gate PR approvals on coverage thresholds, or identify under tested files in a changeset without leaving your conversation. Built in TypeScript with stdio transport and published as an npm package.
