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

PackageDescriptionStatus
@opafex/mcp-enrichmentCompany, contact, email & phone enrichment via Clearbit, Hunter.io, TwilioAvailable
@opafex/mcp-file-processorDocument text extraction, keyword detection, chunkingAvailable
@opafex/mcp-web-researchWeb search (Brave API), SSRF-guarded page fetch, research synthesisAvailable
@opafex/mcp-approval-queueHuman-in-the-loop approval gate — the agent asks, only a person approves (elicitation or CLI)Available
@opafex/knowledge-gridLayered context for agents (a library, in its own repo)Available

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() / buildMCPServer() — Reusable MCP server bootstrap with tool/resource registration and stdio transport
  • ToolContext.elicit — ask the user a question through the client's UI (MCP elicitation), out of the model's reach
  • Validation helpers — Email, domain, phone format validation
