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.

Settings — Multimeter docs

Settings in Multimeter, the AI-powered REST Client for VS Code.Markdown (no JavaScript)# Settings Certificates: see [Certificates](../../features/certificates/index.md). ## Settings Project-level runner settings can be configured in the `setting` section of the env `file:` ```yaml setting: http: version: "auto" timeout: 30000 ``` - `setting.http.version` records the preferred HTTP version as a string (`"auto"`, `"1"`, `"1.1"`, or `"2"`). - HTTP/2 uses a basic request-response transport when supported by the Node runtime. - `setting.http.timeout` sets the default HTTP request timeout in milliseconds. - Per-request `timeout` fields in API files and test HTTP steps still override this default. - If no env file timeout is set, Multimeter uses the built-in default of `30000` milliseconds. ## Reference (types) - `type:` `env` - `variables:` record<string, object (key-value choices; values may be scalars or nested objects/arrays) | array (allowed scalar values)> - `presets:` record<string, record<string, record<string, string|number|boolean|null>>> — bind independent variables; not required for a single nested choice map - `setting:` { http?: { version?: "auto"|"1"|"1.1"|"2", timeout?: number } } - `certificates:` { server_ca?, clients? } ## VS Code Settings Multimeter exposes the following VS Code settings (accessible via Settings or `settings.json`): | Setting | Default | Description | |---------|---------|-------------| | `multimeter.body.auto.format` | `false` | Auto-format response bodies (JSON pretty-print) | | `multimeter.body.lineNumbers` | `false` | Show line numbers in the API tester body editor | | `multimeter.suite.reportSpillBytes` | `2097152` | In-memory suite report budget (bytes) before spilling step details; `0` disables spill — see [Large reports](../suite/reports.md#large-reports) | | `multimeter.editor.fontSize` | `12` | Font size for the YAML editor (range: 8-40) | | `multimeter.editor.yamlPaneSize` | `50%-50%` | Default layout when opening `.mmt` files: YAML%/UI% split, `Only YAML`, `Only UI`, or a fixed YAML width (`400px`…`1300px`) | | `multimeter.editor.collapseDescription` | `false` | Auto-collapse multi-line description fields when opening files | | `multimeter.workspaceEnvFile` | `multimeter.mmt` | Path to the workspace environment file loaded on project open | For AI agents · llms.txt · Home
