MCP Server Integration

The Empe MCP Server enables AI systems like Claude to interact with the Verifier Service through natural language commands. This Model Context Protocol (MCP) server bridges conversational AI and verification operations, making credential verification accessible through simple prompts.

What is MCP?

MCP (Model Context Protocol) servers provide context, tools, and prompts to AI clients. They expose data sources like APIs and databases to make them accessible to AI systems. The Empe MCP server specifically focuses on Self-Sovereign Identity operations, including verification workflows.

Available Verifier Operations

The MCP server provides these verifier-related tools:

Verification Workflows

• generate_verification_qr - Create QR codes for credential verification

• generate_verification_qr_for_vp_query - Generate QR codes for specific VP query verification

• check_verification_status - Monitor verification status in real-time

VP Query Management

• create_vp_query - Create new Verifiable Presentation queries with complex logic

• get_all_vp_queries - List all available VP queries in the system

• get_vp_query_by_id - Retrieve specific VP query details

• delete_vp_query - Remove unused VP queries

Example Use Cases

You can use natural language prompts like:

"Create a verification process that checks if someone has a valid driver's license 
and is over 21 years old."

"Generate a QR code to verify event tickets for the Annual Developer Conference."

"Set up verification that requires either a government ID or a membership card 
with Gold status."

"Check if anyone has scanned the verification QR code I generated earlier."

"Show me all the verification queries we have in the system."

Advanced Verification Examples

The MCP server supports complex verification logic:

"Create a verification that checks if someone has a MembershipCard credential 
with 'Gold' level that hasn't expired yet."

"I want to verify that someone has either a government ID showing they're over 21 
OR a driver's license with class A, B, or C."

"Set up age verification that accepts any credential type as long as the 
birthdate field shows the person is 18 or older."

Real-Time Verification Flow

The MCP server can manage complete verification workflows:

1. Generate Verification Request: Create a QR code with specific requirements

2. Monitor Status: Watch for users scanning the QR code

3. Process Results: Handle successful or failed verifications

4. Update Applications: Notify your systems of verification outcomes

Setup Requirements

Before using the MCP server with the Verifier Service:

1. Deploy a Verifier Service via One-Click Deployment

2. Configure external access (the verifier needs to be accessible from outside your network)

3. Set up the MCP server with your verifier's endpoints and credentials

4. Connect the MCP server to your AI client (like Claude)

Configuration

The MCP server requires these verifier-related environment variables:

VERIFIER_BASE_URL=https://your-verifier-instance.example.com
VERIFIER_CLIENT_URL=https://your-external-accessible-url.com
CLIENT_SECRET=your-verifier-client-secret
SSE_PORT=8080

For detailed setup instructions, see the MCP Server repository.

Integration Benefits

• Rapid Verification Setup: Create complex verification logic through conversation

• Dynamic Requirements: Modify verification criteria without code changes

• Real-Time Monitoring: Track verification status through natural language queries

• Testing and Debugging: Quickly test verification flows with different requirements

• Business Logic Translation: Convert business requirements into technical VP queries

Security Considerations

When using the MCP server with production verifier services:

• Use dedicated test environments for experimentation

• Validate all AI-generated VP queries before production deployment

• Monitor verification requests and results

• Implement proper access controls for the MCP server

• Ensure external verifier URLs use HTTPS and proper authentication

Workflow Integration

The MCP server can be integrated into larger workflows:

1. Dynamic Access Control: Modify verification requirements based on context

2. Event Management: Create time-limited verification flows for events

3. Compliance Checking: Set up verification for regulatory requirements

4. Multi-Step Verification: Chain multiple verification steps together

The MCP server makes credential verification more accessible while maintaining the security and standards compliance of the underlying Verifier Service.
