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"
      }
    }
  }
}

Cursor

Add to your Cursor MCP settings:

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

Remote (HTTP Transport)

For remote MCP clients (including Anthropic Claude), run the HTTP server:

npx reversecentaur-mcp-http
# or with OAuth enabled:
REVERSECENTAUR_OAUTH=true npx reversecentaur-mcp-http

The server listens on port 3001 by default. MCP endpoint: http://localhost:3001/mcp

Windsurf / Other MCP Clients

Any MCP client that supports stdio transport can use this server. Point it at:

npx reversecentaur-mcp
