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.

Use it in comparisons and when passing inputs that should drop a request field. ## In checks and expects Use `omit` with `==` / `!=` to test that a value is missing, `null`, or the omit sentinel (for example after a missing output path): ```yaml - check: ${result.missingField} == omit - check: ${result.token} != omit ``` Object form: - `expected: omit` (unquoted) — assert that the value/path is missing. - For `operator: ==`, a missing path (`undefined`) is treated as `omit` and passes. - For `operator: !=`, the check passes only when the value is present and not omit/null. ```yaml - check: title: username exists actual: ${xxx.body.body.username} operator: "!=" expected: omit - check: title: nickname missing actual: ${xxx.body.body.nickname} operator: "==" expected: omit ``` On call/http `expect` / `require`: - Unquoted `omit` — field/path is missing. - `null` — field exists with a null value. - `!= omit` — field is present. ```yaml - call: getUser expect: body.user.middle_name: omit body.user.first_name: != omit ``` ## In call inputs Pass unquoted `omit` to drop a field from the request the called API builds — the field is removed instead of being sent with a value. Use `"omit"` (quoted) to send the literal string: ```yaml - call: echo id: result inputs: message: omit ``` API files use the same keyword under declared `inputs:` and request fields — see [API → Inputs](../api/inputs.md). --- See also: [Operators](./operators.md) · [Inline expect](./inline-expect.md) · [check](./steps/check.md) · [call](./steps/call.md) For AI agents · llms.txt · Home
