What is the ActionMCP MCP Server?

Rails Engine with MCP compliant Spec.

What the server does

ActionMCP is designed for production Rails environments and does not support STDIO transport. STDIO is not included because it is not production-ready and is only suitable for desktop or script-based use cases. Instead, ActionMCP is built for robust, network-based deployments.

Think of it as a universal interface for connecting AI assistants to external data sources and tools.
