Integration App MCP Server

The Integration App MCP Server is a Model Context Protocol (MCP) server, it provides actions for connected integrations as tools.

For implementing your application, see our example AI Chat Agent:

• AI Chat Agent (MCP Client application)

Prerequisites

• Node.js (v14 or higher)
• An Integration.app account

Installation

git clone https://github.com/integration-app/mcp-server.git
cd mcp-server
npm install
npm run build

Local Development

To run the server locally, start it with:

npm start

Access it at http://localhost:3000

Deployment

Ideally, you'd want to deploy your own instance of this MCP server to any cloud hosting service of your choice.

Docker

The project includes a Dockerfile for easy containerized deployment.

docker build -t integration-app-mcp-server .
docker run -p 3000:3000 integration-app-mcp-server

Connecting to the MCP server

This MCP server support two transports:

Transport	Endpoint	Status
SSE (Server‑Sent Events)	/sse	🔴 Deprecated — deprecated as of November 5, 2024 in MCP spec
HTTP (Streamable HTTP)	/mcp	🟢 Recommended — replaces SSE and supports bidirectional streaming

Authentication

Provide an Integration.app access token via query or header:

?token=ACCESS_TOKEN
Authorization: Bearer ACCESS_TOKEN

SSE (Deprecated)

await client.connect(
  new SSEClientTransport(new URL(`https://<HOSTED_MCP_SERVER_URL>/sse?token=${ACCESS_TOKEN}`))
);

// ----- or -----

await client.connect(
  new SSEClientTransport(
    new URL(
      `https://<HOSTED_MCP_SERVER_URL>/sse`
    )
    {
      requestInit: {
        headers: {
          Authorization: `Bearer ${ACCESS_TOKEN}`,
        },
      },
    }
  )
  );

Streamable HTTP (Recommended)

await client.connect(
  new StreamableHTTPClientTransport(
    new URL(`https://<HOSTED_MCP_SERVER_URL>/mcp?token=${ACCESS_TOKEN}`)
  )
);

// ----- or -----

await client.connect(
  new StreamableHTTPClientTransport(
    new URL(`https://<HOSTED_MCP_SERVER_URL>/mcp`)
    {
      requestInit: {
        headers: {
          Authorization: `Bearer ${ACCESS_TOKEN}`,
        },
      },
    }
  )
);

Cursor Configuration

To use this server with Cursor, update the ~/.cursor/mcp.json file:

{
  "mcpServers": {
    "integration-app": {
      "url": "https://<HOSTED_MCP_SERVER_URL>/sse?token={ACCESS_TOKEN}"
    }
  }
}

Restart Cursor for the changes to take effect.

Claude Desktop Configuration

To use this server with Claude, update the config file (Settings > Developer > Edit Config):

{
  "mcpServers": {
    "integration-app": {
      "url": "https://<HOSTED_MCP_SERVER_URL>/sse?token={ACCESS_TOKEN}"
    }
  }
}

Integration Scoping

By default, the MCP server fetches tools from all active connections associated with the provided token.

You can also get tools for a specific integration by passing the integrationKey query parameter: /mcp?token={ACCESS_TOKEN}&integrationKey=google-calendar

Troubleshooting

• Ensure your access token is valid and you're generating it according to these instructions
• Check the MCP server logs for any errors or issues during startup or connection attempts.
