Codecov MCP Server

Example Use Cases

• 1

  Retrieve commit-level coverage totals and per-file coverage breakdowns from Codecov for analysis or reporting.

• 2

• 3

  Generate human-readable test suggestions based on a Codecov report to guide developers on where to add tests.

Description

This TypeScript MCP server provides tools to fetch coverage totals for a given commit (including per-file breakdowns) using the Codecov API, and a prompt that suggests tests to write based on the report. It is intended to help AI agents identify untested or under-tested parts of a repository and generate actionable test-writing suggestions. The server runs locally via npx and requires a Codecov API key and the repository git URL to operate.
