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.

Copilot workflow — Multimeter docs

Use MCP tools in the first tool-call batch — do not explore CLIs or npm packages first.Markdown (no JavaScript)# Copilot workflow **Use MCP tools in the first tool-call batch** — do not explore CLIs or npm packages first. ``` 1. read_documentation(topic: "workflow" | "test" | ...) ← start here 2. discover_api({ workspaceRoot, apiPath }) ← when APIs involved 3. Copilot edits the file in the workspace 4. validate({ file, workspaceRoot }) ← required after every edit 5. fix → validate again until valid 6. format({ file }) ← optional 7. run({ file, workspaceRoot }) ← when user asks to run ``` The extension also contributes `chatInstructions` and prompt files (`EditMmtFile`, `RunMmtFile` under `commands/`) that auto-apply when working with `.mmt` files (VS Code 1.105+).
