Enrich Layer MCP Server

An MCP (Model Context Protocol) server that provides 25 tools for enriching company, person, contact, school, and job data via the Enrich Layer API.

Use it with any MCP-compatible client: Claude Desktop, Claude Code, Cursor, VS Code, and more.

Quick Start

npx -y @enrichlayer/mcp-server

Set your API key as an environment variable:

export ENRICH_LAYER_API_KEY=your_api_key_here

Get your API key at enrichlayer.com/dashboard.

Configuration

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "enrich-layer": {
      "command": "npx",
      "args": ["-y", "@enrichlayer/mcp-server"],
      "env": {
        "ENRICH_LAYER_API_KEY": "your_api_key_here"
      }
    }
  }
}

Claude Desktop (MCPB Extension)

Download the .mcpb file from Releases and open it in Claude Desktop. You'll be prompted to enter your API key during setup.

Claude Code

claude mcp add enrich-layer -- npx -y @enrichlayer/mcp-server

Then set the env var ENRICH_LAYER_API_KEY in your shell.

Cursor

Add to your Cursor MCP settings:

{
  "mcpServers": {
    "enrich-layer": {
      "command": "npx",
      "args": ["-y", "@enrichlayer/mcp-server"],
      "env": {
        "ENRICH_LAYER_API_KEY": "your_api_key_here"
      }
    }
  }
}

VS Code

Add to your VS Code MCP settings (.vscode/mcp.json):

{
  "servers": {
    "enrich-layer": {
      "command": "npx",
      "args": ["-y", "@enrichlayer/mcp-server"],
      "env": {
        "ENRICH_LAYER_API_KEY": "your_api_key_here"
      }
    }
  }
}

Remote HTTP Server

For remote deployments, the server also supports Streamable HTTP transport:

npm run start:http

This starts an Express server on port 3000 (configurable via PORT env var) with a /mcp endpoint for JSON-RPC and a /health endpoint for health checks.

Usage Examples

1. Look up a company

"Look up the company profile for Stripe"

This calls enrich_company_lookup with company_name: "Stripe" to find the company's professional network URL and profile data.

2. Find a work email by role

"Find the work email for the CTO of Notion"

This chains two tools: first enrich_role_lookup with company_name: "Notion", role: "cto" to find the person, then enrich_work_email with their profile URL to get the email address.

3. Check your credit balance

"How many credits do I have left?"

This calls enrich_credit_balance to show your remaining API credits. Costs 0 credits.
