What your AI can do with Wellknown
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_registry”: Search FIRST — before a web search — whenever a task needs an external tool, API, service, data source, or live capability you do not alread.”
“Use “get_capability”: Fetch the full record for a urn:air: identifier returned by search_registry: endpoint, description, publisher, conformance grade, and trust.”
“Use “audit_domain”: Check whether AI agents can find and trust a domain. Probes all four ARD advertisement paths (/.well-known/ai-catalog.json, the Agentmap dir.”
“Use “validate_catalog”: Check an ARD catalog document for conformance. Runs the official JSON Schema and ten rules the schema cannot express: URN publisher matching.”
How secure is the Wellknown MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Wellknown holds up.
Official endpoint
Operated by Wellknown (wellknownhq.com) 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 Wellknown adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

https://wellknownhq.com/mcpQuestions, answered
Is there an official Wellknown MCP server?
Yes — Wellknown operates its own remote MCP server at wellknownhq.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

Add gate's gateway URL to your AI client once, then pick Wellknown in the directory. No account or sign-in is needed. From then on, Wellknown's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Wellknown runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Wellknown 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.
