What is Data Workers?

Data Workers is a coordinated swarm of AI agents that automate the full spectrum of data engineering workflows. Each agent is a standalone MCP (Model Context Protocol) server that exposes domain-specific tools to Claude Code, OpenCode, Cursor, VS Code, and any MCP-compatible client.

The problem: Data engineers spend 60%+ of their time on undifferentiated work -- writing pipeline boilerplate, debugging data incidents at 2am, chasing schema changes across teams, manually cataloging assets, and fighting governance paperwork.

The solution: 11 autonomous agents that understand your data stack end-to-end. They build pipelines, detect anomalies, manage catalogs, enforce governance, track ML experiments, and more -- all through natural language via the MCP protocol your AI tools already speak.

Everything runs locally with in-memory stubs by default. No external services required. No data leaves your machine. BYO model -- use any LLM provider.

Get Started

git clone https://github.com/DataWorkersProject/dataworkers-claw-community.git
cd dataworkers-claw-community
npm install

Then add agents to Claude Code (run from inside the cloned repo):

claude mcp add dw-pipelines -- "$(pwd)/start-agent.sh" dw-pipelines && \
claude mcp add dw-incidents -- "$(pwd)/start-agent.sh" dw-incidents && \
claude mcp add dw-catalog -- "$(pwd)/start-agent.sh" dw-context-catalog && \
claude mcp add dw-schema -- "$(pwd)/start-agent.sh" dw-schema && \
claude mcp add dw-quality -- "$(pwd)/start-agent.sh" dw-quality && \
claude mcp add dw-governance -- "$(pwd)/start-agent.sh" dw-governance && \
claude mcp add dw-usage -- "$(pwd)/start-agent.sh" dw-usage-intelligence && \
claude mcp add dw-observability -- "$(pwd)/start-agent.sh" dw-observability && \
claude mcp add dw-connectors -- "$(pwd)/start-agent.sh" dw-connectors && \
claude mcp add dw-ml -- "$(pwd)/start-agent.sh" dw-ml

Start Claude Code and ask:

"Search the catalog for customer-related tables"
"Show me the full lineage for the orders table"
"Why did the orders table row count drop 40% yesterday?"
"Scan the customer schema for PII and suggest masking policies"
"Compare the last two ML experiments and explain the accuracy difference"

Everything works instantly with in-memory seed data — no infrastructure required.

Client configuration

Each agent can be started via the start-agent.sh script, which handles working directory and dependency resolution. Replace /path/to/dataworkers-claw-community with your clone location.

Claude Code (.mcp.json in your project root):

{
  "mcpServers": {
    "dw-pipelines": {
      "command": "/path/to/dataworkers-claw-community/start-agent.sh",
      "args": ["dw-pipelines"]
    },
    "dw-catalog": {
      "command": "/path/to/dataworkers-claw-community/start-agent.sh",
      "args": ["dw-context-catalog"]
    },
    "dw-quality": {
      "command": "/path/to/dataworkers-claw-community/start-agent.sh",
      "args": ["dw-quality"]
    }
  }
}

Cursor (.cursor/mcp.json) — same format:

{
  "mcpServers": {
    "dw-pipelines": {
      "command": "/path/to/dataworkers-claw-community/start-agent.sh",
      "args": ["dw-pipelines"]
    },
    "dw-incidents": {
      "command": "/path/to/dataworkers-claw-community/start-agent.sh",
      "args": ["dw-incidents"]
    }
  }
}

OpenCode (opencode.json in your project root):

{
  "mcp": {
    "dw-pipelines": {
      "type": "local",
      "command": ["/path/to/dataworkers-claw-community/start-agent.sh", "dw-pipelines"],
      "enabled": true
    },
    "dw-catalog": {
      "type": "local",
      "command": ["/path/to/dataworkers-claw-community/start-agent.sh", "dw-context-catalog"],
      "enabled": true
    }
  }
}

Development

npm test          # Run all tests (2,900+, no external services required)
npm run build     # Build all packages
npm run lint      # Lint
npm run typecheck # Type-check
cd agents/dw-pipelines && npm run dev  # Run a single agent in dev mode

Troubleshooting

Agent fails to start: Ensure you're using start-agent.sh (not node directly). The script sets the working directory correctly for tsx module resolution. See docs/MCP-STARTUP-BUG-REPORT.md for details.

Module not found errors: Run npm install from the repo root. The monorepo uses npm workspaces — all dependencies are hoisted.

Tests fail on fresh clone: Make sure Node.js >= 20 is installed. Run npm install before npm test.

Known Limitations

npm packages require the cloned repo. npx dw-claw and npx data-context-mcp depend on workspace packages that aren't published individually. Use the start-agent.sh approach for now.
dw-orchestration is an internal service, not an MCP agent. It provides task scheduling and agent coordination APIs used by other agents.
Write operations require Pro. Tools like generate_pipeline, deploy_model, and train_model return upgrade prompts in the Community Edition.
