What its tools let an agent do: 3 read

Install Codecov in Claude Code, Cursor or VS Code

Runs npx -y mcp-server-codecov on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add codecov -- npx -y mcp-server-codecov
Add to Cursor

MCP Server for Codecov

A Model Context Protocol (MCP) server that provides tools for querying Codecov coverage data. Supports both codecov.io and self-hosted Codecov instances with configurable URL endpoints.

📦 Published on npm: @egulatee/mcp-codecov 🐳 Docker image: ghcr.io/egulatee/mcp-server-codecov

Quick Start (Claude Code)

Get started in under 2 minutes:

1. Get your Codecov API token

Create an API token (not an upload token) from your Codecov account:

  1. Go to codecov.io (or your self-hosted URL)
  2. Click your avatar → Settings → Access tab
  3. Click "Generate Token" and name it "MCP Server API Access"
  4. Copy the token value

2. Set your environment variable

Add to your shell profile (~/.zshrc or ~/.bashrc):

export CODECOV_TOKEN="your-api-token-here"

Then reload: source ~/.zshrc

3. Install the MCP server

claude mcp add --transport stdio codecov \
  --env CODECOV_BASE_URL=https://codecov.io \
  --env CODECOV_TOKEN=${CODECOV_TOKEN} \
  -- npx -y @egulatee/mcp-codecov

4. Verify installation

claude mcp get codecov

Expected output: codecov: @egulatee/mcp-codecov - ✓ Connected

That's it! You can now use Codecov tools in Claude Code. See Available Tools below.

Features

  • File-level coverage: Get detailed line-by-line coverage data for specific files
  • Commit coverage: Retrieve coverage statistics for individual commits
  • Repository coverage: Get overall coverage metrics for repositories
  • Pull request coverage: Analyze coverage changes and impact for pull requests
  • Coverage comparison: Compare coverage between branches, commits, or tags
  • Configurable URL: Point to any Codecov instance (codecov.io or self-hosted)
  • Token authentication: API token support for accessing coverage data

Token Types

Important: Codecov has two different types of tokens:

  • Upload Token: Used for pushing coverage reports TO Codecov during CI/CD. Found on your repository's Settings → General page.
  • API Token: Used for reading coverage data FROM Codecov via the API. Created in your Codecov Settings → Access tab.

This MCP server requires an API token, not an upload token.

Available Tools

getfilecoverage

Get line-by-line coverage data for a specific file.

Parameters:

  • owner (required): Repository owner (username or organization)
  • repo (required): Repository name
  • file_path (required): Path to the file within the repository (e.g., 'src/index.ts')
  • ref (optional): Git reference (branch, tag, or commit SHA)

Example:

Get coverage for src/index.ts in owner/repo on main branch

getcommitcoverage
