@mcp-boost/tests

MCP server for test automation in JavaScript/TypeScript repositories.

What It Provides

• Project readiness and changed-file analysis.
• Coverage execution (Jest/Vitest).
• Source/test context extraction.
• Safe test-file writes (test files only, optional TypeScript validation).
• Structured workflow orchestration via MCP tools.

Install

npm install @mcp-boost/tests

Optional native acceleration is resolved via @mcp-boost/tests-native automatically when available.

Run

CLI entrypoint:

npx mcp-tests

Direct Node execution:

node ./dist/server.js

Development

pnpm --filter @mcp-boost/tests build
pnpm --filter @mcp-boost/tests dev

Custom typing rules (optional)

To enforce stricter type generation in tests, add one of these files at repo root:

• .mcp-tests.rules.json
• .mcp-testsrc.json

Example:

{
  "typeSafety": {
	"enforceNoAny": true,
	"requireTypeImports": true,
	"preferTypedFactories": true
  },
  "additionalRules": [
	"Import component props from the source module; never redefine prop types in tests.",
	"For API payload fixtures, use exported DTO types from src/types."
  ]
}

get_test_guidelines will include these rules in the generated guidance.

get_test_context also returns requiredTypeImports per analyzed file with inferred symbols and source module paths so test generation can import concrete types instead of falling back to any.
