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 B2B lead enrichment MCP server directly into your IDE. By integrating this Model Context Protocol interface, you allow your coding assistants to query real-time company profiles and technographic data without leaving your development environment.

Core Features

This MCP server exposes a standardized set of tools designed for deep data synthesis:

• Firmographic Data: Retrieve real-time company size, revenue buckets, and headquarters location.
• Technographic Intelligence: Access granular data on tech stacks, infrastructure providers, and SaaS utilization.
• Intent Signals: Filter leads by high-intent triggers, mapped through Zod-validated parameters to ensure 100% type safety.
• Hallucination Prevention: By enforcing strict schema definition for every parameter, the MCP server forces the LLM to provide exact inputs (e.g., valid domains, ISO-country codes), effectively eliminating parameter hallucinations common in unstructured RAG workflows.

Configuration for Cursor/VS Code

To connect the enrichment tool, add the following configuration to your mcp.json file (typically located in ~/Library/Application Support/Cursor/User/globalStorage/mcp-server.json or equivalent VS Code config directory):

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

JSON-RPC Response Structure

When the LLM triggers the enrich_lead tool, the server returns a structured JSON-RPC payload optimized for context injection:

{
  "jsonrpc": "2.0",
  "result": {
    "companyName": "Acme Corp",
    "industry": "Cloud Infrastructure",
    "technographics": ["AWS", "Kubernetes", "Datadog"],
    "intentSignals": ["High", "Recent Series B"],
    "confidenceScore": 0.92
  },
  "id": 1
}

The Value Proposition: Risk-Free Metered Billing

We prioritize developer ROI by implementing a Confidence-Based Billing model. You are only billed for enrichments where the Confidence Score > 0.6. If the API cannot reliably verify a company profile or returns low-quality data (Confidence Score ≤ 0.6), the query is marked as a failure and costs $0. This allows you to build autonomous SDR agent swarms without worrying about "garbage-in, garbage-out" expenses draining your credits.
