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

The most efficient way to inject real-time B2B firmographics into your local AI development environment is by deploying a B2B lead enrichment MCP server directly into your IDE’s context providers. By leveraging the Model Context Protocol, developers can grant Cursor or VS Code native access to live company profiles and intent signals, effectively eliminating manual research workflows and data entry friction.

Core Features and Data Integrity

Our MCP-native API server bridges the gap between raw web-scale data and LLM reasoning engines. It delivers structured firmographic data (revenue, headcount, location), technographic insights (SaaS stack, infrastructure providers), and real-time intent signals (hiring trends, product launches).

To solve the perennial issue of LLM parameter hallucinations, we utilize strict Zod-based schema annotations in our tool definitions. This ensures that the model provides correctly formatted domains and company names, as the server-side validator rejects malformed inputs before the enrichment query ever reaches the data provider.

Connecting Cursor to the MCP API

To enable the tool, add the following configuration to your mcp.json file. This allows Cursor to execute enrich_lead queries directly from the chat interface.

{
  "mcpServers": {
    "b2b-enrichment": {
      "command": "npx",
      "args": [
        "-y",
        "@agent-infra/lead-enrichment-mcp"
      ],
      "env": {
        "LEAD_ENRICHMENT_API_KEY": "your_api_key_here"
      }
    }
  }
}

Expected JSON-RPC Tool Output

When the LLM triggers the enrich_lead tool, it receives a clean, deterministic JSON response, enabling high-precision reasoning in your autonomous SDR agents:

{
  "jsonrpc": "2.0",
  "result": {
    "companyName": "Acme Corp",
    "industry": "Cloud Infrastructure",
    "technographics": ["AWS", "Kubernetes", "Datadog"],
    "intentSignals": {
      "hiringTrend": "aggressive",
      "recentFunding": "Series C"
    },
    "confidenceScore": 0.94
  },
  "id": "req-123"
}

Risk-Free Metered Billing

We prioritize developer ROI by implementing a Confidence-Based Billing model. Our infrastructure tracks the confidenceScore of every lookup; if the data provider returns a result with a confidence score of 0.6 or lower, or if the query fails to return actionable firmographics, you are not charged. You only pay for high-quality, actionable B2B intelligence, making this the most cost-effective way to scale autonomous sales swarms.
