RationalBloks MCP Server

Deploy production APIs in minutes. 44 tools for projects, schemas, deployments, and graph data.

What Is This?

RationalBloks MCP lets AI agents (Claude, Cursor, etc.) deploy production APIs from a JSON schema. No backend code to write. No infrastructure to manage.

"Create a task management API with tasks, projects, and users"
→ 2 minutes later: Production API running on Kubernetes

Installation

pip install rationalbloks-mcp

      "env": {
        "RATIONALBLOKS_API_KEY": "rb_sk_your_key_here"
      }
    }
  }
}

Claude Desktop - Add to claude_desktop_config.json:

{
  "mcpServers": {
