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.

They are managed via the UI and stored in VS Code workspace state: | Setting | Default | Description | |---------|---------|-------------| | Server CA Enabled | `false` | Use configured server CA certificates | | Client Enabled | `true` | Enable/disable individual client certificates | For CLI usage, sensible defaults are applied: - SSL validation is enabled - Self-signed certificate failures are retried and reported as warnings - All configured certificates are enabled ### Self-signed certificate warning Multimeter first verifies SSL certificates. If an HTTPS request fails because of a self-signed certificate, Multimeter retries the request without certificate validation and reports the certificate issue as a warning, matching Postman-style behavior. ### Legacy TLS compatibility Multimeter automatically enables the Node/OpenSSL compatibility flags needed for many legacy TLS and mTLS gateways, avoids HTTPS TLS session reuse, and keeps TLS version negotiation automatic. No TLS-specific user configuration is required. For AI agents · llms.txt · Home
