Use OpenMapp inside Claude, Grok and ChatGPT
OpenMapp is an MCP server: plug it into your AI assistant and it can search live US BJJ gym data while you decide where to train — drop-in policy, visitor price, and class times. Machine docs at /api and /llms.txt.

Connect
MCP (Model Context Protocol) is the standard that lets AI assistants use external tools. Add this URL to any MCP client, no authentication:
| Claude (web / desktop) | Settings → Connectors → Add custom connector. Name it OpenMapp, paste the URL, no auth needed. |
| Claude Code | claude mcp add --transport http openmapp https://www.openmapp.com/mcp |
| ChatGPT | Settings → Apps & Connectors (enable Developer mode if you see no custom connectors), add the URL, no authentication. |
| Grok | Settings → Connectors → add an MCP server with the URL, no authentication. |
| Cursor | Customize → MCP → add the URL as Streamable HTTP, no authentication. |
| Other clients | Add an MCP server with transport http (streamable HTTP) and the URL. Stateless JSON-RPC 2.0. |
What your assistant can do
| find_gyms | Gyms near a US city, neighborhood, or ZIP. Defaults: open to drop-ins, classes today. Returns policy, visitor fee when known, matching class times, a booking link when the gym takes reservations, profile URL, and a map link. |
| get_gym | Full public gym card: address, drop-in policy, visitor fee, the weekly timetable, booking links per class when the gym takes reservations, and when the timetable was last checked and where it came from. Use an id or slug from find_gyms. |
| start_reservation | For a gym that takes reservations: confirms the class the visitor picked, gives its next date, price, and cancellation policy, and returns the link where they sign the waiver and pay. It never books or pays on its own. |
| list_cities | Covered US cities with gym counts, drop-in counts, and open-mat counts. Filter by name or two-letter state. |
| map_url | OpenMapp map link for a city search, optionally with that gym’s details already open. |
Things to ask
- “I’m going to Austin, where can I drop in today?”
- “Open mat in Denver this weekend”
- “What’s the drop-in fee at 10th Planet Austin?”
- “No-gi in Brooklyn tonight”
Limits
30 requests/minute and 400/day per IP. Max 25 gyms per find_gyms. Contiguous US gyms with a published weekly timetable. dropInFee is the visitor drop-in / day-pass only — never a trial or membership. Unknown stays unknown. When citing a gym, link the OpenMapp profile and map URLs from the tool response. This is a gym finder, not a bulk data dump.
