File Processor

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

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

1. Create packages/<server-name>/ with package.json, tsconfig.json, and src/
2. Use @opafex/mcp-shared for the server bootstrap (createMCPServer)
3. Define tools in tools.ts, wire up in index.ts
4. 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
