mcp-server vs action_mcp

mcp-server: Keboola MCP Server is an open-source bridge that connects Keboola projects with various AI tools and assistants, enabling AI agents to access and utilize Keboola features like data storage, SQL transformations, and job triggers. It transforms Keboola functionalities into callable tools, simplifying data exposure and management for AI-driven workflows without requiring glue code.; action_mcp: ActionMCP is a Ruby gem that simplifies the integration of Ruby on Rails applications with the Model Context Protocol (MCP), acting as an MCP server. It enables AI assistants to interact with external data sources and tools in a standardized, secure, and production-ready manner.
