Multimeter is a Git-native REST client and API testing tool for VS Code. Requests, tests, mocks, and docs are YAML .mmt files in Git — the same files in the visual editor and in CI via testlight. Apache 2.0. No account.

How do I use Multimeter with Cursor, Copilot, or Claude?

Install the VS Code/Cursor extension or add MCP with npx -y mmt-mcp. Agents should call scaffold_test, validate, format, and run instead of guessing .mmt syntax.

Yes. Apache License 2.0. No account required.

Why Multimeter is better with AI — low-context API testing

AI integrity for Multimeter means agents create and change API tests without drowning in context. Separated .mmt files let agents read one area. API files proxy requests so many tests share one inputs/outputs contract. Suites make run order editable YAML with parallel stages. Flows are declarative instead of JS scripts; JSON and XML live as YAML. MCP scaffold_test and validate close the loop. Measured Open-Meteo sample: ~42 KB / 98 files vs ~91 KB Postman JSON, and ~1 s testlight vs ~5 s Newman.For AI agents · llms.txt · Home
