aiworker-data MCP

Remote MCP server (Streamable HTTP, x402 v2 USDC pay-per-call) - a deterministic-first data layer for agents with no account, no API key and no subscription. Each request carries a price in the x402 402 PAYMENT-REQUIRED response; the agent pays in USDC on Base or Solana and retries. Nothing settles unless the request succeeds. 20 tools live-probed in this sweep (server v0.2.0).

Why This Matters for Operators

The x402 model removes the friction that kills agent adoption of paid data: no signup, no key vault, no subscription - the agent sees the price in the 402 response, pays per call and gets deterministic results. For operators the interesting tools are the market ones: news_search covers twelve crypto and markets feeds refreshed every ten minutes, social_mentions searches Hacker News and Polymarket comments for any term, and topic_brief produces a sourced brief where every paragraph cites its source pages. Deterministic means no LLM in the loop for most routes, so the numbers do not hallucinate.

Installation

claude mcp add aiworker --transport http https://aiworker.duckdns.org/mcp

Send the request, read the price from the PAYMENT-REQUIRED header of the 402 response, pay it with any x402 client (@x402/fetch, x402-axios, the agentcash MCP) and retry. Framework wrappers for LangChain.js, the Vercel AI SDK and ElizaOS live in the ai-worker227/aiworker-examples repo.

Configuration

{
  "mcpServers": {
    "aiworker": {
      "url": "https://aiworker.duckdns.org/mcp"
    }
  }
}

No keys anywhere. The client handles payment; the health endpoint and all documentation pages are free.

Business Relevance

  • Market researchers get sourced briefs and claim checks with verbatim evidence at $0.05-$0.10 per call.
  • Crypto operators run token and wallet due diligence (token_report, trade_gate) before exposure.
  • News and content teams search twelve market feeds and HN mentions deterministically.
  • Quant-curious operators replay published rules over resolved Polymarket markets at $0.25 a backtest.

Integration with CorpusIQ

aiworker-data is a pay-per-call external evidence service that complements CorpusIQ's subscription model: a CorpusIQ agent can spend cents on news_search and social_mentions when a report needs external market context, while first-party business data continues to flow through the CorpusIQ connectors. The x402 pattern also demonstrates the no-key model CorpusIQ could offer for metered external data in future.

Limitations

  • Homelab-hosted endpoint (duckdns): uptime and latency are not vendor-guaranteed.
  • Pay-per-call means an agent in a loop can spend real money; cap calls at the client level.
  • Solo-built project with no third-party track record or public server repo.
  • Deterministic data comes from third-party sources (DefiLlama, Blockscout, Gamma); check freshness per tool.
