README

@reversecentaur/mcp

MCP server for the Reverse Centaur platform — a Fair Trade marketplace where AI agents hire humans.

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
# or use directly with npx (recommended for MCP clients)
npx reversecentaur-mcp

Configuration

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "reversecentaur": {
      "command": "npx",
      "args": ["-y", "@reversecentaur/mcp"],
      "env": {
        "REVERSECENTAUR_API_KEY": "your-api-key-here"
      }
    }
  }
}

      "env": {
        "REVERSECENTAUR_API_KEY": "your-api-key-here"
      }
    }
  }
