How to Give Cursor and VS Code Copilot Live B2B 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 within your development environment. By connecting the B2B Lead Enrichment MCP server to Cursor or VS Code, AI agents can autonomously research prospects, validate technographic stacks, and verify lead quality using real-time data instead of relying on stale training weights.

Core Features of the Lead Enrichment MCP

This MCP server provides a high-fidelity bridge between your AI agent and a live database of global company profiles. Unlike standard REST API integrations that require manual prompting or custom functions, this implementation uses the Model Context Protocol to expose tools with strict Zod-validated schemas, effectively eliminating parameter hallucinations.

  • Deep Firmographics: Access real-time employee counts, revenue brackets, and HQ locations for millions of entities.
  • Technographic Intelligence: Identify the exact tech stack (e.g., AWS, React, Salesforce) used by a target lead to tailor development or sales scripts.
  • Active Intent Signals: Retrieve data on recent funding rounds, hiring surges, or technology migrations.
  • Confidence Scoring: Every enrichment includes a confidenceScore (0.0 - 1.0), allowing you to build logic-gates for high-integrity autonomous SDR workflows.

Configuration for Cursor and VS Code

To enable these capabilities in Cursor or VS Code (via the MCP extension), add the following configuration to your MCP settings. This connects your local agent to the production-grade Worker endpoint.

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

Standardized JSON-RPC Response Example

When the agent invokes the enrich_lead tool, it receives a structured JSON-RPC payload. This clean data structure ensures that the LLM can parse firmographic attributes without guessing field names.

{
  "tool": "enrich_lead",
  "parameters": { "domain": "stripe.com" },
  "response": {
    "companyName": "Stripe, Inc.",
    "industry": "Financial Services",
    "employeeCount": 8000,
    "technographics": ["AWS", "Ruby on Rails", "Kubernetes", "React"],
    "intentSignals": {
      "hiringTrend": "High",
      "recentFunding": "Series I"
    },
    "confidenceScore": 0.98,
    "status": "enriched"
  }
}

Risk-Free Metered Billing Architecture

Building AI agents can be expensive if you pay for low-quality data. Our B2B Lead Enrichment MCP implements a Risk-Free Metered Billing model. Your account is only debited for successful enrichments that return a Confidence Score > 0.6.

If the server cannot find a high-quality match, or if the data is insufficient to meet the confidence threshold, the query cost is $0. This allows developers to build high-volume SDR swarms and autonomous research agents without the financial risk of paying for "data not found" errors or hallucinated placeholders.
