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.

Suite — Multimeter docs

Use type: suite to define a suite MMT file. A suite runs multiple items together — tests, APIs, HTTP/Bruno files, or other suites. Open a suite file in VS…Markdown (no JavaScript)# Suite Use `type: suite` to define a suite MMT file. A suite runs multiple items together — tests, APIs, HTTP/Bruno files, or other suites. Open a suite file in VS Code to get the **suite panel** on the right (YAML stays on the left). ![Suite panel — overview cards, exports, and tests](../../screenshots/suite-panel.png) ## Suite panel UI ### Top bar | Control | What it does | |---|---| | `title` | Suite title from `title:` (shown with the layers icon) | | {{btn:type-hierarchy-sub:Flow chart}} | Opens a read-only hierarchy view of suite items | | {{btn:edit:Edit Suite}} | Switches to **edit mode** — see [Edit Suite](./edit.md) | See also: [Flow chart](../../features/flow-chart.md) ### Run bar | Control | What it does | |---|---| | {{btn:play:Run suite}} | Runs all suite items. While running, turns into **Stop suite**. Shortcut: **⌘Enter** (macOS) / **Ctrl+Enter** | | **More** (chevron next to Run) | While idle: **Run in Core**, **Run in testlight** (opens a terminal with `testlight run <file> …` plus workspace env flags), **Clear**. While running: **Pause** / **Resume** (first), then the other More actions | | {{btn:export:Export}} | Export the run report (HTML, MMT, Markdown, or JUnit XML). Disabled until a run completes | | **YAML ERROR** | Shown when the suite YAML has parse, schema, or formatting (key-order) problems — click to jump to the issue | **Run in Core** and **Pause** / **Resume** behave like the [test runner](../test/index.md#run-bar). Closing the tab while a UI suite run is active prompts to save — **Cancel** keeps the run; see [Panels — Status bar](../../panels/index.md#status-bar). ### Before and after a run | Section | What you see | |---|---| | **Overview** | **PASSED**, **FAILED**, **TOTAL**, and **DURATION** summary cards (after a run) — see [Reports](./reports.md) | | `environment` | Preset, env file, and inline variables when `environment:` is configured | | `servers` | Mock server files listed in `servers:` | | **Exports** | Report export paths from `export:` | | `filter` | When `filter:` is set: only/skip tags and, after a run, **Total: N skipped** — see [Tag filter](./execution.md#tag-filter) | | **Items** | Item tree grouped by execution stage — expand a test to see step reports — see [Reports](./reports.md#items-tree) | ### Item tree Each item shows an icon for its `type:` | Type | Icon meaning | |---|---| | **API** | HTTP or WebSocket API file | | **Test** | Test file with steps/stages | | **Suite** | Nested suite | | **Server** | Mock server file — started before items in the same stage | | **Missing** | Referenced file not found | | **Cycle** | Circular reference detected (not executed) | Each item and stage group has a **Run** button for partial runs (subtree execution). Use **More** next to Run for **Run in Core**. See [Execution — partial runs](./execution.md#partial-runs). ## Supported - [items](./items.md) — tests, APIs, HTTP/Bruno files, nested suites - [import](./import.md) — data file imports - [Execution](./execution.md) — parallel stages with `then`, mock servers - [Exports](./exports.md) · [CLI](./cli.md) Sample: ```yaml type: suite title: Smoke Tests tags: - smoke items: - test/login_and_get_user_info.mmt - test/create_session.mmt - test/get_user_info.mmt ``` ## Suite elements - [Quick start](./quick-start.md) · [Edit Suite](./edit.md) · [Reports](./reports.md) · [Report overview](../report/index.md) · [Run a suite](../../tasks/run-suite.md) - [import](./import.md) · [items](./items.md) · [Execution](./execution.md) · [Exports](./exports.md) · [CLI](./cli.md) · [Reference](./reference.md) - Example: [Suite tag filter](../../../examples/intermediate/29_suite_tag_filter/README.md) For AI agents · llms.txt · Home
