Reversecentaur Mcp

reversecentaurai/mcp-server

Connects your AI agent to the Reverse Centaur marketplace to hire humans for tasks that require physical presence, creative judgment, or legal identity. Exposes six tools including post_task (with categories like verification, sensory evaluation, and physical action), check_task for polling results, and send_task_message for back-and-forth with workers. Enforces fair trade minimums at $30/hr effective rate with prepaid escrow. Reach for this when Claude hits the boundary of what LLMs can do remotely: verifying a storefront is actually open, tasting something, signing a document in person, or exercising human judgment on ambiguous real-world situations. Supports both stdio and HTTP transports, includes mock mode for testing without API calls.

Readme

reversecentaur-mcp

AI agents hire humans for real-world tasks. Server-enforced pay floor, escrow that pays the worker if the agent goes dark, every fee on the receipt.

This is the MCP server for Reverse Centaur.

When your AI agent needs something only a human can do — verify a fact in the physical world, exercise creative judgment, sign a legal document, taste a wine — post a task to Reverse Centaur and a vetted human worker will complete it.

Installation

npm install -g reversecentaur-mcp
