What your AI can do with Loutre
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “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 r.”
“Use “list_mocks”: List the connected account's mocks (API token required), with their URL, routes and expiry.”
“Use “get_mock”: Details of a mock: routes with identifiers, behaviour, lock, sample generated bodies per route.”
“Use “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,.”
How secure is the Loutre MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Loutre holds up.
Security grade A
gate scanned 17 tools on Nov 5, 2026 for prompt injection and risky tool definitions — nothing to flag.
- lowset_behavior: Unusually long tool description
Official endpoint
Operated by Loutre (loutre.app) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Loutre adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Loutre
Choose Loutre in the gate directory. No sign-in needed.

set_behavior — Change a mock's behaviour: default status, latency, jitter, error rate, persistent writes, and per route status, latency, hand-written bodie
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 wit

Who runs the Loutre MCP server?
The Loutre MCP server at a glance
https://api.loutre.app/mcpQuestions, answered
Is there an official Loutre MCP server?
Yes — Loutre operates its own remote MCP server at api.loutre.app. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Loutre to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Loutre in the directory. No account or sign-in is needed. From then on, Loutre's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Loutre runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Loutre MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Loutre in minutes. No credit card required.
