- Support for environment files
- Support for global variables
- Detailed test results including:
- Overall success/failure status
- Test summary (total, passed, failed)
- Detailed failure information
- Execution timings
To install Postman Runner for Claude Desktop automatically viaSmithery:
npx -y @smithery/cli install mcp-postman --client claude
# Clone the repository git clone <repository-url> cd mcp-postman # Install dependencies pnpm install # Build the project pnpm build
Add the server to your Claude desktop configuration file at~/Library/Application Support/Claude/claude_desktop_config.json:
{ "mcpServers": { "postman-runner": { "command": "node", "args": ["/absolute/path/to/mcp-postman/build/index.js"] } } }
Runs a Postman collection and returns the test results.
- collection(required): Path or URL to the Postman collection
- environment(optional): Path or URL to environment file
- globals(optional): Path or URL to globals file
- iterationCount(optional): Number of iterations to run
{ "success": true, "summary": { "total": 5, "failed": 0, "passed": 5 }, "failures": [], "timings": { "started": "2024-03-14T10:00:00.000Z", "completed": "2024-03-14T10:00:01.000Z", "duration": 1000 } }
You can use the server in Claude by asking it to run a Postman collection:
"Run the Postman collection at /path/to/collection.json and tell me if all tests passed"
- Use the run-collection tool
- Analyze the test results
- Provide a human-friendly summary of the execution
