Claude Code: deny. ### `clear_rules` - The description's first verb is "remove": a word for removing or ending something. Description, as the server wrote it: ```untrusted-server-text Remove every conditional rule of a route. ``` ### `delete_mock` - The name "delete_mock" says "delete": a word for removing or ending something. - The description says "Permanently delete". Description, as the server wrote it: ```untrusted-server-text Permanently delete a mock and its kept schema. ``` ## Changes things (12) Creates or changes something that can be changed back. Claude Code: ask. ### `add_rule` - The name "add_rule" says "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `call_mock` - The name "call_mock" says "call": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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 (POST, PUT, PATCH, DELETE) are persisted when persistent state is on. For a GraphQL mock, POST to its GraphQL path with the body { "query": "…", "variables": { … } }; mutations are persisted the same way. ``` ### `clear_requests` - The name "clear_requests" says "request": a word for a change. Description, as the server wrote it: ```untrusted-server-text Empty the mock's request log. ``` ### `create_mock` - The name "create_mock" says "create": a word for a change. - Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it. Description, as the server wrote it: ```untrusted-server-text 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 Bruno collection (JSON export, or .bru files one after the other), a HAR file (headers and cookies are dropped, data is generated), a json-server db.json (records served as they are), curl commands, or a GraphQL schema (SDL or introspection JSON; Pro plan: queries, mutations and introspection answered on POST /graphql). OpenAPI 3.2 is read too. Give the document in `spec`, or its public address in `url` (then the mock re-reads it every six hours and follows changes). Returns the URL, the route list and an ownerToken to keep for later changes. Data is realistic and coherent, generated once. Without an account the mock lives seven days. ``` ### `regenerate_mock` - The description's first verb is "generate": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `replay_request` - The name "replay_request" says "request": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `reset_state` - The name "reset_state" says "reset": a word for a change. Description, as the server wrote it: ```untrusted-server-text Forget persisted writes (POST, PUT, PATCH, DELETE): the generated collections come back as they were. ``` ### `set_access` - The name "set_access" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text Lock a mock with a token (private) and/or restrict the allowed browser origins. Pro plan. ``` ### `set_behavior` - The name "set_behavior" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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_domain` - The name "set_domain" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `set_response` - The name "set_response" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text Set the JSON body a route returns for a given status (hand-written response); a null body restores the generated response. ``` ### `sync_mock` - The name "sync_mock" says "sync": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Only reads (3) Looks things up and changes nothing. Claude Code: allow. ### `get_mock` - The name "get_mock" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Details of a mock: routes with identifiers, behaviour, lock, sample generated bodies per route. ``` ### `get_requests` - The name "get_requests" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `list_mocks` - The name "list_mocks" says "list": a word for reading. - Tag untrusted-input: The description's first sentence says "list" and "url": it reads web pages, which anyone can write. Description, as the server wrote it: ```untrusted-server-text List the connected account's mocks (API token required), with their URL, routes and expiry. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `loutre`: ```json { "permissions": { "allow": [ "mcp__loutre__list_mocks", "mcp__loutre__get_mock", "mcp__loutre__get_requests" ], "ask": [ "mcp__loutre__create_mock", "mcp__loutre__call_mock", "mcp__loutre__set_behavior", "mcp__loutre__set_response", "mcp__loutre__add_rule", "mcp__loutre__regenerate_mock", "mcp__loutre__replay_request", "mcp__loutre__clear_requests", "mcp__loutre__sync_mock", "mcp__loutre__set_domain", "mcp__loutre__reset_state", "mcp__loutre__set_access" ], "deny": [ "mcp__loutre__clear_rules", "mcp__loutre__delete_mock" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__loutre__create_mock`: outbound - `mcp__loutre__list_mocks`: untrusted-input
