How to Give Cursor and VS Code Copilot Live Firmographic Tools via MCP

The most efficient way to give LLMs native access to live B2B firmographics and intent data without custom middleware is by deploying an MCP-native B2B lead enrichment MCP server directly into your IDE. By utilizing the Model Context Protocol, developers can now equip their local AI agents with real-time company profiles and technographic data, ensuring high-fidelity outputs for sales and research workflows.

Core Features

Our B2B lead enrichment MCP server provides high-density data payloads that are pre-structured for LLM consumption. Key technical highlights include:

  • Firmographic Intelligence: Access real-time companyName, industry, employeeCount, and annualRevenue mapping.
  • Technographic Stack: Deep insights into the current tech stack, including CRM integration, cloud infrastructure, and marketing automation tools.
  • Predictive Intent Signals: Normalized scores representing buying propensity.
  • Hallucination Mitigation: All tool parameters utilize strict Zod annotations, forcing the LLM to adhere to schema constraints for domain or company_name inputs, preventing common parameter hallucination issues.

Configuring Cursor / VS Code Copilot

To integrate the API into your environment, add the following configuration to your mcp.json settings file. This links the Claude-compatible MCP server to your local agentic tools:

{
  "mcpServers": {
    "b2b-lead-enrichment": {
      "command": "npx",
      "args": [
        "-y",
        "@agent-infra/lead-enrichment-mcp"
      ],
      "env": {
        "API_KEY": "your_api_key_here",
        "ENDPOINT": "https://lead-enrichment-mcp.agent-infra.workers.dev/mcp"
      }
    }
  }
}

JSON-RPC Response Example

When an LLM calls the enrich_lead tool, the server returns a clean, sanitized JSON-RPC response. This structure ensures your agent processes only valid, high-confidence data:

{
  "jsonrpc": "2.0",
  "result": {
    "companyName": "Acme Corp",
    "industry": "SaaS",
    "technographics": ["Salesforce", "AWS", "HubSpot"],
    "intentSignals": {
      "marketPulse": 0.89,
      "buyingStage": "researching"
    },
    "confidenceScore": 0.94
  },
  "id": 1
}
Enter fullscreen mode Exit fullscreen mode

The Value Proposition: Risk-Free Metered Billing

We prioritize developer ROI by implementing a Risk-Free Metered Billing structure. You are exclusively billed for successful enrichments where the Confidence Score > 0.6. If the API returns low-quality data or fails to find a match, the query costs $0, ensuring your autonomous SDR swarms remain cost-effective while scaling.
