EvHenter

You run an Event Aggregation platform with a Sanity.io backend and an MCP server to power ChatGPT Apps. This MCP server connects to your Sanity data, exposes endpoints for events, locations, categories, and venues, and lets you seed data, develop locally, and deploy to hosting services. It is designed for local development and for serving MCP clients that need to query and manage events and related data.

How to use

To use the MCP server with a client, first ensure the server is running in development mode. The server exposes an SSE endpoint to establish a persistent connection and a messages endpoint to send user interactions or chat messages. Your MCP client will connect to the SSE stream at the following address and send messages to the chat flow via the messages endpoint.

Key endpoints you will leverage are:

• SSE connection at GET /sse to subscribe to event streams
• Messages endpoint at POST /messages?sessionId=xxx to send messages to an active session
