DataMerge MCP MCP Server for Claude

Overview

DataMerge provides a native Model Context Protocol server for company and contact intelligence. AI agents can enrich domains, poll async jobs, fetch corporate hierarchies, search decision-makers, and discover lookalike companies without bespoke integration code.

Documentation is at datamerge.ai/docs/mcp.md. The remote endpoint is https://mcp.datamerge.ai; local stdio mode uses the @datamerge/mcp npm package.

Features

• Company enrichment with async job polling and wait helpers.
• Corporate hierarchy traversal for parents, subsidiaries, and global ultimate owners.
• Contact search and enrichment by title, location, LinkedIn URL, or name plus domain.
• Lookalike company discovery from seed domains or companies.
• Credits balance and health-check tools.
• Saved list management for companies and contacts.

Use Cases

• Enrich a target account list before a quarterly territory review.
• Map Stripe's corporate hierarchy for vendor risk analysis.
• Find CFO and CTO contacts at a mid-market SaaS company.
• Build a lookalike list from five seed domains in the same ICP.
• Check remaining credits before a large batch enrichment job.

Installation

Remote HTTP (Cursor, Claude, Windsurf)

{
  "mcpServers": {
    "datamerge": {
      "url": "https://mcp.datamerge.ai",
      "headers": {
        "Authorization": "Token your-api-key"
      }
    }
  }
}

Local stdio

claude mcp add datamerge --env DATAMERGE_API_KEY=your-api-key -- npx -y @datamerge/mcp

Claude Code remote shortcut

claude mcp add --transport http datamerge https://mcp.datamerge.ai

Add the Authorization: Token header in your client auth settings.

Configuration

{
  "mcpServers": {
    "datamerge": {
      "url": "https://mcp.datamerge.ai",
      "type": "http",
      "headers": {
        "Authorization": "Token YOUR_DATAMERGE_API_KEY"
      }
    }
  }
}

You can also call configure_datamerge per session if the key is not preset.

Examples

Enrich a domain

Enrich stripe.com and return legal entity, country, and employee count.

Hierarchy lookup

Show the full corporate hierarchy for Shopify including subsidiaries.

Contact search

Find the CEO and CTO at shopify.com and return verified email addresses if available.

Security

• Failed lookups typically cost zero credits, but successful enrichment still exposes sensitive business data.
• Restrict API keys to users who may export contact information.
• Rotate keys if they appear in MCP debug logs.

Troubleshooting

401 or configure_datamerge prompts

Set DATAMERGE_API_KEY or pass the key through configure_datamerge.

Jobs stuck in pending

Poll with get_company_enrichment_result or use start_company_enrichment_and_wait for simpler flows.

Missing hierarchy nodes

Some private or regional entities may be absent from vendor coverage; verify with a second source.

Windsurf config shape

Windsurf uses serverUrl instead of url; see DataMerge docs for client-specific JSON.
