Building rules and zoning plans, in every conversation
Your assistant asks the same Struck you use in the app: the same regulation library, the same zoning data, and every answer with its sources.
Step 1
Copy the server URL
Every assistant connects to the same address:
https://unravel.struck.build/api/mcp
Step 2
Add Struck to your assistant
Add it as a custom connector or MCP server in Copilot Studio, ChatGPT, Gemini, Claude or Claude Code. The steps for each are below.
Step 3
Sign in and ask
Sign in once with your Struck account. Then ask about building rules or a zoning plan, and your assistant calls Struck when it needs to.
