Analyze test coverage from LCOV files - makes AI agents coverage-aware without wasting tokens
Analyze test coverage from LCOV files - makes AI agents coverage-aware without wasting tokens. The test mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 4 defined tools rather than through you.
Give your coding and testing agent eyes: MCP server that provides instant, reliable, token-efficient test coverage data for any programming language (LCOV based)
Everything the assistant can do here goes through one of these:
coverage_summary — The coverage_summary tool exposed by this servercoverage_file_summary — The coverage_file_summary tool exposed by this serverstart_recording — The start_recording tool exposed by this serverget_diff_since_start — The get_diff_since_start tool exposed by this serverInstallation goes through your MCP client rather than a global install: point it at test-coverage-mcp on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Test's toolset — coverage_summary, coverage_file_summary, start_recording and 1 more — is a fair guide to whether it matches your workflow. It is maintained by goldbergyoni; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
