MCP & Claude

MCP (Model Context Protocol) is an open standard that lets Claude call external tools and retrieve structured context during a conversation. On Belay implements an MCP server at https://app.onbelay.ai/api/mcp.

When Claude connects to On Belay via MCP, it gains access to four tools that surface your organization's context — who you are, what groups you're in, what integrations you can use, and how to authenticate against them.

Authentication uses OAuth 2.0 with PKCE. No tokens are embedded in config files or shared manually — the flow is handled automatically when you add the server.

Open Claude Desktop and navigate to Settings → Developer → MCP Servers. Add the following server configuration to your claude_desktop_config.json:

{
  "mcpServers": {
    "onbelay": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/inspector"],
      "env": {
        "SERVER_URL": "https://app.onbelay.ai/api/mcp",
        "BEARER_TOKEN": "<your-token>"
      }
    }
  }
}

Replace <your-token> with your On Belay bearer token. Find your token in Dashboard → Settings → Claude connection or complete the OAuth flow from the settings page to generate one.

claude.ai supports MCP servers natively. No config file needed — it's a UI flow.
