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.

CLI — Multimeter docs

Use testlight run to run a suite from the command line or CI:Markdown (no JavaScript)# Running suites from the CLI Use `testlight run` to run a suite from the command line or CI: ```sh testlight run path/to/suite.mmt --env-file env.mmt --preset dev ``` Select tests by tag (replaces the suite file’s `filter:`): ```sh testlight run path/to/suite.mmt --tag smoke --skip-tag flaky ``` `--tag` / `--skip-tag` are repeatable and accept comma-separated lists. See [Tag filter](./execution.md#tag-filter) and the [suite tag filter example](../../../examples/intermediate/29_suite_tag_filter/README.md). Stages run sequentially; items within each stage run in parallel. Configure env for suite runs with the root-only `environment:` field or CLI flags. See [Environment CLI](../env/cli.md) · [Suite exports](./exports.md).
