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.

Bruno — Multimeter docs

Use Bruno .bru and .bruno request files with Multimeter while keeping Bruno-compatible source files.Markdown (no JavaScript)# Bruno Use Bruno `.bru` and `.bruno` request files with Multimeter while keeping Bruno-compatible source files. ## Run directly See [Spec editor](./spec-editor.md) for the {{btn:list-tree}} request picker, **All** vs single request, and {{btn:save-as}}. In VS Code, open a `.bru` file with **Open With...** → **Multimeter Bruno Test Editor**, or **Open as MMT**. Opening a single `.bru` does **not** pull in sibling requests from the collection. Click {{btn:list-tree}} to pick **All** (one sequential test) or that request (API **Send**). ## Run a collection Open the collection’s `bruno.json` the same way (**Open With...** / **Open as MMT**). Multimeter walks the collection folder (skipping `collection.bru`, `folder.bru`, `environments/`, and paths listed in `bruno.json` `ignore`). Click {{btn:list-tree}} to pick **All** (every request as one sequential test) or a single request (API **Send**). The left editor shows `bruno.json` (JSON). Requests are ordered by `meta.seq`, then file path. ## Import in tests Reference Bruno files from `type: test` `.mmt` files: ```yaml type: test title: Reuse Bruno request import: profile: requests/get_profile.bru steps: - call: profile ``` See [import](../files/test/import.md). ## Convert to MMT Right-click a `.bru` or `.bruno` file in the Explorer and choose **Convert to MMT...**. Multimeter generates matching `api/` and `tests/` files you can edit in the normal Multimeter UI. Example output: [Bruno convert example](../../examples/intermediate/25_convert_to_mmt/bruno/README.md) Full sandbox Bruno collection: [professional Bruno convert](../../examples/professional/04_convert_to_mmt/bruno/README.md) ## Supported syntax Common single-request `.bru` structure: - `meta.name` → test title and request id - HTTP method blocks: `get`, `post`, `put`, `patch`, `delete`, `head`, `options`, `trace` - `url`, `body`, and `auth` from the method block - `headers`, `params:query`, and `body:json` / `body:xml` / `body:text` - `auth:bearer` → `Authorization: Bearer ...` header - `vars:*` blocks for local substitution; `{{name}}` resolves from Bruno vars, then `<<e:name>>` - Random variables (`{{$uuid}}`, etc.) map to Multimeter `r:` tokens - Simple `expect(res.status).to.equal(200)` assertions become Multimeter `expect` checks ## Limitations - Pre-request and post-response scripts are not executed as Bruno scripts - File bodies, multipart helpers, and advanced auth may need conversion to editable `.mmt` for full control ## See also - [Bruno file examples](../../examples/intermediate/16_bruno_files/README.md) — open `library/bruno.json` for the full collection, or any `.bru` for a single request - [HTTP file](./http-file.md) · [Postman](./postman.md) For AI agents · llms.txt · Home
