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.

import — Multimeter docs

import in Multimeter, the AI-powered REST Client for VS Code.Markdown (no JavaScript)# import ### `import` The `import` section brings external files into a test. Each entry is an **alias** (key) and a **path** (value). **Prefer `+/…` project-root paths** for APIs and shared fixtures whenever the project has a [`multimeter.mmt`](../env/project-root.md) at its root — imports stay stable if you move the test file. Use paths relative to the current `.mmt` file only for siblings in the same folder (or when there is no project root marker). ## Importable file types | File type | Extensions | Use with | Docs | |-----------|------------|----------|------| | API definition | `.mmt` (`type: api`) | `call` | [call](./steps/call.md) | | Test flow | `.mmt` (`type: test`) | `call` (nested test) | [call](./steps/call.md) | | Mock server | `.mmt` (`type: server`) | `run` | [Mock servers in tests](../server/in-tests.md) | | Judge | `.mmt` (`type: judge`) | `judge` | [Judge](../judge/index.md) · [Judge steps](./steps/judge.md) | | HTTP Client file | `.http`, `.https` | `call` (converted to a test flow) | [HTTP file](../../integration/http-file.md) | | Bruno request | `.bru`, `.bruno` | `call` (converted to a test flow) | [Bruno](../../integration/bruno.md) | | Data file | `.csv`, `.json`, `.yaml`, `.yml` | `for`, `${alias.path}` | [Data-driven tests](../../features/data-driven-tests.md) | | JS helper module | `.js`, `.cjs`, `.mjs` | `js` steps | [JS helper modules](./steps/js.md#js-helper-modules) | ```yaml import: api: +/api/forecast_current.mmt # preferred — project root (multimeter.mmt) login: +/tests/login.mmt helpers: +/helpers/xxx.js # Same-folder / local-only (OK when no project root, or for true siblings): sibling: ./nearby_test.mmt requests: requests.http # HTTP Client file, converted to a test flow profile: profile.bru # Bruno request file, converted to a test flow users: ../data/users.csv # relative — prefer +/data/users.csv when possible ``` HTTP and Bruno files imported this way are converted internally to test flows and can be called like normal test imports: ```yaml steps: - call: requests ``` See also: [Cache](./cache.md) · [Data-driven tests](../../features/data-driven-tests.md) · [Data imports](../../features/data-imports.md) · [js step — JS helper modules](./steps/js.md#js-helper-modules) For AI agents · llms.txt · Home
