Apollo.io MCP server for AI agents

Apollo.io MCP Server is a powerful implementation of the Model Context Protocol that connects AI assistants to Apollo.io data. It allows AI systems to enrich data for people and organizations, perform searches, find job postings, and execute Apollo.io operations through natural language commands without leaving the AI assistant interface.

Installation

To set up the Apollo.io MCP Server:

# Clone the repository
git clone https://github.com/lkm1developer/apollo-io-mcp-server.git
cd apollo-io-mcp-server

# Install dependencies
npm install

# Build the project
npm run build

Configuration

Before using the server, you need to obtain an Apollo.io API access token:

Go to your Apollo.io Account
Navigate to Settings > API
Generate an API key

You can provide this token in either of two ways:

As an environment variable:
```
APOLLO_IO_API_KEY=your-api-key
```
As a command-line argument:
```
npm start -- --api-key=your-api-key
```

For development, create a .env file in the project root:

APOLLO_IO_API_KEY=your-api-key

Starting the Server

To start the MCP server:

# Start the server
npm start

# Or with a specific API key
npm start -- --api-key=your-api-key

# Run the SSE server with authentication
npx mcp-proxy-auth node dist/index.js

Authentication Setup

The server uses the mcp-proxy-auth package for authentication:

Set the authentication server URL:

export AUTH_SERVER_URL=https://your-auth-server.com/verify

The SSE URL will be available at:
```
localhost:8080/sse?apiKey=apikey
```

The authentication proxy:

Intercepts requests to your SSE server
Verifies API keys against your authentication server
Only allows authenticated requests to reach your SSE endpoint

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

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

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
