Test Intel MCP server

test-intel-mcp

Turn JavaScript and TypeScript coverage artifacts into practical test priorities. The server reads local coverage and source files, identifies gaps, scores function complexity, and suggests focused test cases without sending code to an external service.

Start in one minute

Add one local server entry to any stdio-compatible MCP client:

{
  "mcpServers": {
    "test-intel": {
      "command": "npx",
      "args": ["-y", "@barissozudogru/test-intel-mcp"]
    }
  }
}

Then ask the client to inspect an existing coverage file:

Use test-intel to analyze coverage/lcov.info, identify the highest-impact gaps,
and suggest tests for the most complex uncovered function.

No account, API key, or hosted service is required. File access is restricted to the directory where the server starts.

Proof on this repository

Running the complexity tool against the real src/paths.ts file produces:

Function complexity analysis for: src/paths.ts
Total functions analyzed: 1

Priority | Function        | Line | Cyclomatic | Branches | Loops
---------|-----------------|------|------------|----------|------
low      | deriveTestPaths | 11   | 3          | 1        | 1

Summary: 0 critical, 0 high, 0 medium, 1 low priority

The same server reads lcov, Istanbul JSON, and Cobertura files to surface uncovered functions, lines, and branches.

A pinned p-limit 7.3.1 case study reproduces coverage from the upstream project's 22 passing tests. test-intel-report reduces its lcov artifact to two uncovered lines and one uncovered branch while preserving the original coverage file for inspection.

If this saves you time, consider starring the repository. It helps other developers find it.
