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 match the OpenMapp map: open to drop-ins, classes today. Returns policy, visitor fee when known, matching class times, profile URL, and a map link. |
| get_gym | Full public gym card: address, drop-in policy, visitor fee, and the weekly timetable. Use an id or slug from find_gyms. |
| 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.
