MCP Integration

Connect AI assistants to Belong using Model Context Protocol.

You can connect AI assistants and developer tools to Belong using Model Context Protocol (MCP).

This allows you to:

  • Ask natural-language questions about your events or places
  • Interact with your token collections and schedules
  • Use Belong's API without writing custom integration code

Belong has two MCP surfaces:

Use caseEndpointAuth
Public AI assistants and external connectorshttps://join.belong.net/functions/v1/belong-agent-mcp/mcpOAuth 2.1 with email-code sign-in
Trusted backend or first-party integrationshttps://api.belong.net/mcpx-api-key

Use the public assistant MCP for ChatGPT-style or OAuth-capable remote MCP clients. Use the API-key MCP only from trusted developer tooling, servers, or first-party integrations that already hold a Belong API key.

Getting Started

Belong provides ready-to-use MCP servers. Choose the endpoint that matches your integration.

Public Assistant MCP

This is the recommended endpoint for external assistants:

The public assistant MCP uses OAuth 2.1, PKCE, scoped permissions, and email-code sign-in. Protected actions such as organizer updates, venue operations, and signing-link preparation require the user to connect their Belong account. Sensitive wallet or payment operations return a Belong confirmation link rather than executing directly in chat.

Backend API-Key MCP

The backend MCP remains available for trusted integrations:

EnvironmentMCP Server URL
Productionhttps://api.belong.net/mcp

This endpoint uses the same x-api-key header as the Belong REST API. Follow Getting an API Key to create one for your environment.

LLM Manifest

MCP-capable clients that support discovery can bootstrap backend API-key tooling from the plain-text manifest at https://api.belong.net/api/v3/llms.txt. OAuth-capable public assistants should use the public assistant MCP endpoint above and its OAuth discovery metadata.

How to Connect with AI Tools

MCP clients commonly use JSON configuration like the examples below.

Belong uses Streamable HTTP. The public assistant MCP responds with JSON when the client accepts JSON and streams tool calls as text/event-stream when the client advertises SSE support.

Public Assistant MCP

For OAuth-capable clients that support remote MCP servers:

{
  "mcpServers": {
    "belong": {
      "url": "https://join.belong.net/functions/v1/belong-agent-mcp/mcp"
    }
  }
}

Backend API-Key MCP

For trusted clients or servers that use a Belong API key:

{
  "mcpServers": {
    "belong-api": {
      "url": "https://api.belong.net/mcp",
      "headers": {
        "x-api-key": "YOUR_API_KEY_HERE"
      }
    }
  }
}

For MCP clients that only support local (stdio) servers, use a remote proxy only with the backend API-key MCP:

{
  "mcpServers": {
    "belong-api": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://api.belong.net/mcp",
        "--header",
        "x-api-key: ${AUTH_TOKEN}"
      ],
      "env": {
        "AUTH_TOKEN": "YOUR_API_KEY_HERE"
      }
    }
  }
}

This allows local-only clients to communicate with Belong's backend MCP through a local proxy.

Replace YOUR_API_KEY_HERE with your actual Belong API key. Keep API keys server-side or in trusted developer tooling only; do not paste API keys into public assistant chats.

How to Connect

Cursor

  1. Open Cursor
  2. Go to Cursor SettingsMCPAdd new global MCP server
  3. Paste the public assistant MCP or backend API-key MCP configuration above, depending on the auth model your workspace supports

Claude Desktop

  1. Download and install Claude Desktop
  2. Open the configuration file:
    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: %APPDATA%\Claude\claude_desktop_config.json
  3. Add the public assistant MCP or backend API-key MCP configuration above, depending on the auth model your client supports

Postman

  1. Open Postman
  2. Click Add → Select MCP
  3. Enter the backend MCP server URL: https://api.belong.net/mcp
  4. Go to the Headers section and add x-api-key with your API key value

What You Can Do

Once connected, you can ask your AI assistant questions like:

  • "Show me all my upcoming events"
  • "What's the current value of my tokens?"
  • "Create a new event for next Friday"
  • "List all my venues"

The AI will interact with your Belong account directly through the MCP connection, making it easy to manage your events and tokens without switching between applications.
