Mcp Enrichment

authSTDIOregistry active

Summary

Connects Claude to Clearbit, Hunter.io, and Twilio for entity enrichment workflows. You get tools to look up company data, find employee contacts, verify email addresses, and validate phone numbers without writing integration code yourself. Ships with mock mode when API keys aren't provided, so you can prototype enrichment flows before paying for credits. Built by Intelagent as part of a broader MCP toolkit that includes document processing and planned research servers. Install via npm, point your MCP client at the built index.js, and pass API credentials through environment variables. Useful when you're building lead qualification, data hygiene, or outreach automation into Claude workflows.

Opafex MCPs

Open-source Model Context Protocol servers by Opafex. Each server is a standalone npm package usable with Claude Code, Claude Desktop, Cursor, and any MCP-compatible client.

Servers

Package	Description	Status
`@opafex/mcp-enrichment`	Company, contact, email & phone enrichment via Clearbit, Hunter.io, Twilio	Available
`@opafex/mcp-file-processor`	Document text extraction, keyword detection, chunking	Available
`@opafex/mcp-web-research`	Web search, page fetch, research synthesis	Planned
`@opafex/mcp-approval-queue`	Human-in-the-loop approval workflows	Planned
`@opafex/mcp-knowledge-grid`	Document indexing, semantic search, context composition	Planned

Quick Start

# Clone and install
git clone https://github.com/opafex/opafex-mcps.git
cd opafex-mcps
npm install
npm run build

# Run the enrichment server (mock mode — no API keys needed)
node packages/enrichment/dist/index.js

Add to Claude Code

Create or edit .mcp.json in your project root:

{
  "mcpServers": {
    "enrichment": {
      "command": "node",
      "args": ["/path/to/opafex-mcps/packages/enrichment/dist/index.js"],
      "env": {
        "CLEARBIT_API_KEY": "sk-...",
        "HUNTER_API_KEY": "...",
        "TWILIO_ACCOUNT_SID": "...",
        "TWILIO_AUTH_TOKEN": "..."
      }
    }
  }
}

All servers work in mock mode when API keys are omitted — great for development and testing.

Development

npm install          # Install all dependencies
npm run build        # Build all packages
npm test             # Run all tests

Adding a New Server

Create packages/<server-name>/ with package.json, tsconfig.json, and src/
Use @opafex/mcp-shared for the server bootstrap (createMCPServer)
Define tools in tools.ts, wire up in index.ts
Add tests in __tests__/

See packages/enrichment as a reference implementation.

Shared Utilities

@opafex/mcp-shared provides:

createMCPServer() — Reusable MCP server bootstrap with tool/resource registration and stdio transport
Validation helpers — Email, domain, phone format validation
