How it's different
Remote MCP endpoint ingested from the official registry and probed by FastDrop.
Ingested from the official MCP Registry
FastDrop pulled this entry from the official MCP Registry as app.loutre/loutre and probed the endpoint. The maker did not submit it, so the outbound link is not endorsed
and the description is not theirs.
If this is your server, claim the listing to edit it and take ownership. The registry index lists everything else still awaiting a probe.

create_mockCreate 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")
list_mocksList the connected account's mocks (API token required), with their URL, routes and expiry.
get_mockDetails of a mock: routes with identifiers, behaviour, lock, sample generated bodies per route.
call_mockCall 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-loutr
set_behaviorChange 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 clear
set_responseSet the JSON body a route returns for a given status (hand-written response); a null body restores the generated response.
add_ruleAdd 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 orde
clear_rulesRemove every conditional rule of a route.
