How do I install MCP Enrichment?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does MCP Enrichment need an API key?

The publisher lists these environment variables: CLEARBIT_API_KEY, HUNTER_API_KEY, APOLLO_API_KEY, TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN, ENRICHMENT_CACHE_TTL.

What transport does MCP Enrichment use?

MCP Enrichment runs locally over stdio.

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
