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 API server directly into your IDE. By connecting the B2B Lead Enrichment MCP server, developers can transform Cursor or VS Code into an intelligent sales agent capable of qualifying leads, mapping technographics, and identifying buyer intent in real-time.

Core Features of the B2B Enrichment MCP

Integrating a specialized B2B lead enrichment MCP server provides your AI agents with structured, high-fidelity data layers that generic LLMs lack. This server provides comprehensive firmographic data (revenue, headcount, industry), technographic profiles (software stack, infrastructure), and real-time intent signals directly via a standard JSON-RPC interface.

To ensure reliability, all tool parameters are governed by strict Zod annotations. This prevents the common issue of LLM parameter hallucinations—where the model might invent non-existent company attributes—by forcing the model to adhere to a schema-validated request structure before the API call is ever made.

Configuring Cursor or VS Code for Live Enrichment

To enable these capabilities in your IDE, add the following configuration to your MCP settings. This connects your environment to the production-grade Worker endpoint.

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

Real-Time JSON-RPC Response Payload

When the enrich_lead tool is invoked, the MCP server returns a clean, structured JSON object. This allows the LLM to process complex company profiles without manual parsing or data cleaning.

{
  "jsonrpc": "2.0",
  "id": "1",
  "result": {
    "companyName": "Acme Corp",
    "industry": "Enterprise SaaS",
    "technographics": ["AWS", "Salesforce", "Kubernetes", "React"],
    "intentSignals": {
      "hiringTrend": "High",
      "fundingRound": "Series C",
      "recentNews": "Expanding into EMEA markets"
    },
    "confidenceScore": 0.94,
    "metadata": {
      "lastUpdated": "2023-10-27T14:22:00Z"
    }
  }
}

Risk-Free Metered Billing for AI Workflows

Traditional B2B data providers charge per request, regardless of whether the data is found or accurate. This MCP server utilizes a Risk-Free Metered Billing model optimized for autonomous SDR swarms. You are only billed for successful enrichments that return a Confidence Score > 0.6. If the server returns low-quality data or fails to locate the entity, the query cost is exactly $0, allowing you to scale automated lead qualification scripts without the risk of burning through your budget on "not found" results.
