What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• create_mock

  Create a hosted mock from an OpenAPI 3.0/3.1 or Swagger 2.0 document (YAML or JSON), from TypeScript types (interfaces, types, enums: CRUD routes derived, or a route map type keyed like "GET /users") or from a Postman v2 collection, an Insomnia export (v4 JSON or v5 YAML), a Brun

• list_mocks

  List the connected account's mocks (API token required), with their URL, routes and expiry.

• get_mock

  Details of a mock: routes with identifiers, behaviour, lock, sample generated bodies per route.

• call_mock

  Call a route of the mock like an HTTP client would and return the status, the x-loutre-* headers and the body. The headers x-loutre-status, x-loutre-delay, x-loutre-count, x-loutre-message and x-loutre-seed are honoured; latency is not awaited, it is reported in delayMs. Writes (

• set_behavior

  Change a mock's behaviour: default status, latency, jitter, error rate, persistent writes, and per route status, latency, hand-written bodies, rules. Merge semantics: missing keys are kept, null clears.

• set_response

  Set the JSON body a route returns for a given status (hand-written response); a null body restores the generated response.

• add_rule

  Add a conditional response to a route: when the request matches the conditions (query, header, path param, body field), the mock answers with this status, body and latency. Rules are evaluated in order, the first match wins; x-loutre-* headers keep priority.

• clear_rules

  Remove every conditional rule of a route.

• regenerate_mock

  Generate a new data set (new seed), for the whole mock or for one route and the routes sharing its collection. A full new set forgets persisted writes.

• get_requests

  The latest requests received by the mock, most recent first: method, path, query, status, headers and body as received (body cut at 8 KB), where the answer came from, latency. Each entry has an id for replay_request.

• replay_request

  Replay a request from the log exactly as it was received (same method, path, headers and body) against the mock as it is now, and return the answer. Useful after changing a rule, a body or a scenario.

• clear_requests

  Empty the mock's request log.

• sync_mock

  Re-read the schema at the mock's source URL now and update the mock if it changed (routes, fields; settings kept, persisted writes forgotten). force regenerates even when the document is unchanged.

• set_domain

  Serve the mock under the account's own hostname (Pro): declares it at Cloudflare and returns the CNAME to create (hostname → target) plus the current status; call again without hostname to re-check, or with hostname null to remove it.

• reset_state

  Forget persisted writes (POST, PUT, PATCH, DELETE): the generated collections come back as they were.

• set_access

  Lock a mock with a token (private) and/or restrict the allowed browser origins. Pro plan.

• delete_mock

  Permanently delete a mock and its kept schema.
