How to Give Cursor and VS Code Copilot Live B2B Firmographic Tools via MCP

To equip Cursor or VS Code with native B2B lead enrichment capabilities, you must integrate a Model Context Protocol (MCP) server that provides real-time company profiles and intent signals directly to the LLM's context window. Using a B2B lead enrichment MCP server allows your AI editor to query firmographics, technographic stacks, and buying intent via standardized JSON-RPC tools, eliminating the need for manual data scraping or context switching.

Core Features of the Enrichment MCP

This MCP server acts as a bridge between the Model Context Protocol and high-fidelity B2B data providers. By exposing a structured enrich_lead tool, it allows LLMs to retrieve deep metadata using only a company domain or email address.

  • Firmographic Intelligence: Retrieve real-time data on company revenue, headcount, industry classification, and headquarters location.
  • Technographic Analysis: Identify the underlying software stack of a target company, including cloud providers, CRM usage, and marketing automation tools.
  • Intent Signal Processing: Access live triggers such as recent funding rounds, hiring surges, or technology shifts.
  • Zero-Hallucination Schemas: All tool parameters are defined using strict Zod annotations. This forces the LLM to provide valid domains and prevents the "hallucination" of contact data by enforcing a rigid JSON-RPC structure.

Configuration for Cursor and VS Code

To enable these tools in Cursor or VS Code (via the Claude Dev or Roo Code extensions), add the following configuration to your mcpServers settings. This connects your IDE directly to the hosted MCP endpoint.

{
  "mcpServers": {
    "b2b-lead-enrichment": {
      "command": "curl",
      "args": [
        "-s",
        "https://lead-enrichment-mcp.agent-infra.workers.dev/mcp"
      ],
      "env": {
        "API_KEY": "YOUR_PRODUCTION_KEY"
      }
    }
  }
}

Standardized JSON-RPC Response Payload

When the LLM invokes the enrich_lead tool, it receives a clean, structured object. This ensures the agent can reason about the data programmatically without parsing messy HTML or unstructured text.

{
  "jsonrpc": "2.0",
  "id": "1",
  "result": {
    "companyName": "ExampleCorp",
    "industry": "Enterprise Software",
    "headcount": "500-1000",
    "technographics": ["AWS", "Salesforce", "React"],
    "intentSignals": [
      {"type": "Funding", "detail": "Series B - $40M", "date": "2023-11-15"}
    ],
    "confidenceScore": 0.94,
    "status": "enriched"
  }
}

Risk-Free Metered Billing

Traditional B2B data APIs charge per request, regardless of whether the data is accurate or found. This MCP server utilizes a Confidence-First Billing model. Your account is only debited for successful enrichments where the confidenceScore is greater than 0.6. If the tool returns a "not found" status or low-confidence data, the query cost is $0, making it the most cost-effective solution for building autonomous SDR swarms and high-volume lead processing agents.
