What your AI can do with PermitStack
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_permits”: Search U.S. building permits by location (city, state, ZIP code, or a lat/lng radius), category, status, property type, filing or issue date.”
“Use “get_permit”: Look up a permit by the permit number assigned by the issuing jurisdiction, optionally narrowed by city and state. The number is matched exa.”
“Use “get_property_history”: Permit history for one property, looked up by street address (house number and street name, e.g. '123 Main St'). Optional city, state and ZI.”
“Use “search_contractors”: Search contractors by name, city, state or specialty. Returns up to 25 contractors per call with the contractor UUID, name, licence number a.”
How secure is the PermitStack MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how PermitStack holds up.
Official endpoint
Operated by PermitStack (permit-stack.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 PermitStack adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

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