The Registry MCP server,
connected in one click.
The MCP server that vets MCP servers: identity, risk grade and per-tool risk before you install. Connect the official Registry MCP server to Claude, ChatGPT, or Cursor through gate — one gateway URL, no config files, security-checked.

What your AI can do with Registry
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “check_mcp_server”: Check an MCP server against the PolicyLayer registry BEFORE installing or allowing it. Accepts a registry slug, an npm package name (scoped.”
“Use “check_mcp_stack”: Check a whole MCP stack against the PolicyLayer registry in one call — up to 25 servers, each given as candidate identifiers (npm package na.”
“Use “search_registry”: Search the PolicyLayer registry of published MCP servers by name, slug or package substring. Returns candidate matches with risk grade, iden.”
“Use “check_tool”: One tool's full risk classification on a published MCP server: category, severity, risk analysis and evidence, OWASP classes, parameter sche.”
How secure is the Registry MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Registry holds up.
Official endpoint
Operated by Registry (policylayer.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 Registry 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 Registry
Choose Registry in the gate directory. No sign-in needed.
Use it anywhere
Registry's tools are live in every AI client you've connected — with rules and logging built in.

Who runs the Registry MCP server?
The Registry MCP server at a glance
https://api.policylayer.com/mcpQuestions, answered
Is there an official Registry MCP server?
Yes — Registry operates its own remote MCP server at api.policylayer.com. 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 Registry to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Registry in the directory. No account or sign-in is needed. From then on, Registry's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Registry runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Registry 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 Registry in minutes. No credit card required.
