Loutre
Hosted mock APIs from OpenAPI, TypeScript or Postman: realistic data, errors and latency on demand.
What it does
Loutre is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
From the publisher's description, Electra Index matched it to one capability: api integration. That makes it a candidate for tasks such as integrate two APIs or automate business workflows.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

17 tools offered to AI assistants
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 Insolist_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 awaiset_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-* headclear_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.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
