Summary
Extracts text from documents, detects language, pulls keywords, and chunks content for RAG pipelines. Built by Intelagent as part of their open-source MCP collection. Runs over stdio, works in mock mode without dependencies for testing. If you're preprocessing files before feeding them into embeddings or need to break PDFs and docs into semantic chunks, this handles the grunt work. Check the file-processor package in their monorepo for the full tool list. Pairs with their planned knowledge-grid server for the full indexing and retrieval stack.
Keeps your Mac awake while Claude Code, Codex or Cursor works. Lets it sleep when they are done.

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.
