This MCP server provides a comprehensive set of tools for interacting with the Apollo.io API, allowing AI assistants to:

• Enrich data for people and organizations
• Search for people and organizations
• Find job postings for specific organizations
• Perform Apollo.io operations without leaving your AI assistant interface

• Seamless AI Integration: Connect your AI assistants directly to Apollo.io data
• Simplified API Operations: Perform common Apollo.io tasks through natural language commands
• Real-time Data Access: Get up-to-date information from Apollo.io
• Secure Authentication: Uses Apollo.io's secure API token authentication
• Extensible Design: Easily add more Apollo.io API capabilities as needed

# 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

The server requires an Apollo.io API access token. You can obtain one by:

1. Going to your Apollo.io Account
2. Navigating to Settings > API
3. Generating an API key

You can provide the token in two ways:

1. As an environment variable:

   APOLLO_IO_API_KEY=your-api-key
   

2. As a command-line argument:

   npm start -- --api-key=your-api-key
   

For development, create a .env file in the project root to store your environment variables:

APOLLO_IO_API_KEY=your-api-key

# 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

The SSE server uses the mcp-proxy-auth package for authentication. To implement authentication:

1. Install the package:

   npm install mcp-proxy-auth

2. Set the AUTH_SERVER_URL environment variable to point to your API key verification endpoint:

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

3. Run the SSE server with authentication:

   npx mcp-proxy-auth node dist/index.js

4. The SSE URL will be available at:

   localhost:8080/sse?apiKey=apikey
   

   Replace apikey with your actual API key for authentication.

The mcp-proxy-auth package acts as a proxy that:

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

This MCP server is designed to work with AI assistants that support the Model Context Protocol. Once running, the server exposes a set of tools that can be used by compatible AI assistants to interact with Apollo.io data.

The server exposes the following powerful Apollo.io integration tools:

1. people_enrichment

   • Use the People Enrichment endpoint to enrich data for 1 person
   • Parameters:
     • first_name (string, optional): Person's first name
     • last_name (string, optional): Person's last name
     • email (string, optional): Person's email address
     • domain (string, optional): Company domain
     • organization_name (string, optional): Organization name
   • Example:

     {
       "first_name": "John",
       "last_name": "Doe",
       "email": "john.doe@example.com"
     }

2. organization_enrichment

   • Use the Organization Enrichment endpoint to enrich data for 1 company
   • Parameters:
     • domain (string, optional): Company domain
     • name (string, optional): Company name
   • Example:

     {
       "domain": "apollo.io"
     }

3. people_search

   • Use the People Search endpoint to find people
   • Parameters:
     • q_organization_domains_list (array, optional): List of organization domains to search within
     • person_titles (array, optional): List of job titles to search for
     • person_seniorities (array, optional): List of seniority levels to search for
   • Example:

     {
       "person_titles": ["Marketing Manager"],
       "person_seniorities": ["vp"],
       "q_organization_domains_list": ["apollo.io"]
     }

4. organization_search

   • Use the Organization Search endpoint to find organizations
   • Parameters:
     • q_organization_domains_list (array, optional): List of organization domains to search for
     • organization_locations (array, optional): List of organization locations to search for
   • Example:

     {
       "organization_locations": ["Japan", "Ireland"]
     }

5. organization_job_postings

   • Use the Organization Job Postings endpoint to find job postings for a specific organization
   • Parameters:
     • organization_id (string, required): Apollo.io organization ID
   • Example:

     {
       "organization_id": "5e60b6381c85b4008c83"
     }

The server is designed to be easily extensible. To add new Apollo.io API capabilities:

1. Add new methods to the ApolloClient class in src/apollo-client.ts
2. Register new tools in the setupToolHandlers method in src/index.ts
3. Rebuild the project with npm run build
