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.

Auth — Multimeter docs

Auth in Multimeter, the AI-powered REST Client for VS Code.Markdown (no JavaScript)# Auth ### Auth Use the `auth` field for built-in authentication. It generates the appropriate header (or query parameter) automatically. Explicit `headers.Authorization` always takes precedence. #### Bearer token ```yaml auth: type: bearer token: <<e:token>> ``` Generates: `Authorization: Bearer <resolved-token>` #### Basic auth ```yaml auth: type: basic username: <<e:user>> password: <<e:pass>> ``` Generates: `Authorization: Basic <base64(username:password)>` #### API key (header) ```yaml auth: type: api-key header: X-API-Key value: <<e:api_key>> ``` Generates: `X-API-Key: <resolved-value>` #### API key (query parameter) ```yaml auth: type: api-key query: api_key value: <<e:api_key>> ``` Appends `?api_key=<resolved-value>` to the query parameters. #### OAuth 2.0 client credentials ```yaml auth: type: oauth2 grant: client_credentials token_url: https://auth.example.com/token client_id: <<e:client_id>> client_secret: <<e:client_secret>> scope: read write ``` At runtime, fetches an access token from `token_url` and sets `Authorization: Bearer <access_token>`. Notes - All `auth` field values support environment variables (`<<e:var>>`), inputs (`<<i:param>>`), and random tokens (`r:uuid`). - Auth headers are masked in logs to prevent accidental credential exposure.
