README

b2match-mcp

Read-only MCP server for the B2match event and matchmaking platform.

This package is designed to be run locally by the user via npx and stdio MCP transport.

Disclaimer: This project is unofficial and is not affiliated with, endorsed by, or supported by B2match. It uses B2match's undocumented web GraphQL API, so field availability can change without notice. Use it in accordance with B2match's Terms of Service and GDPR. Participant profiles can be other people's personal data — keep exports local, respect each event's visibility rules, and do not harvest or republish personal data.

Read-only and privacy guarantees

The MCP server sends only GraphQL query operations. Mutations and subscriptions are parsed and rejected before any network call.
Known "read-looking" write operations are explicitly blocked, including profile-view, mark-as-read, session-attendance, and bookmark mutations.
B2match can still update its own read/seen counters when certain query fields are selected. See Server-side side effects.
It never calls Plausible, Sentry, Google Analytics, HubSpot, LinkedIn pixel, or any non-B2match analytics endpoint.
It makes no external calls other than https://api.b2match.com/v4/query and the B2match Google login URL opened by the CLI.
No telemetry or analytics are collected by this package.
Tokens are never printed by tools or status commands.
Tokens are stored in the OS keychain when available, otherwise in a 0600 config file.

Install / run

Requires Node.js 22 or newer. On macOS with Apple Silicon, the recommended install path is npx; no native build step is required for the auth storage path.

npx -y b2match-mcp

From a checkout:

npm install
npm run build
node dist/cli.js

MCP client config

Claude Desktop

{
  "mcpServers": {
    "b2match": {
      "command": "npx",
      "args": ["-y", "b2match-mcp"]
    }
  }
}

Cursor

    "b2match": {
      "command": "npx",
      "args": ["-y", "b2match-mcp"]
    }
  }
}

VS Code

Add to .vscode/mcp.json or user MCP settings:

{
  "servers": {
    "b2match": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "b2match-mcp"]
    }
  }
}

For local development from this checkout:

{
  "mcpServers": {
    "b2match": {
      "command": "node",
      "args": ["/absolute/path/to/b2match-mcp/dist/cli.js"]
    }
  }
}

Authentication

Public event data works anonymously. Personal data such as viewer profile, active events, meetings, schedule, conversations, notifications, and availability requires a locally stored B2match session token.

macOS / Linux login

b2match-mcp login https://www.b2match.com/e/<event-slug>
# or: npx b2match-mcp login https://www.b2match.com/e/<event-slug>

The default command:

Resolves the event anonymously and asks B2match for its Google login URL.
Launches your installed Chrome, Chromium, Edge, or Brave as a separate process.
Uses a dedicated persistent profile under the tool config directory, not your everyday browser profile.
Opens a remote-debugging port on 127.0.0.1 for that dedicated profile only (not your everyday browser). The port
