ValterAndrei/rails-mcp-playground

Demonstrates MCP protocol implementation in Rails by exposing Post CRUD operations as JSON-RPC tools via a `/mcp` endpoint, enabling LLMs and intermediary agents to discover available tools through `tools/list` and execute them via `tools/call`. The server maps tool invocations directly to Rails models and business logic, bridging the gap between language models and database-backed Rails applications. Integrates with LLM clients (ChatGPT, Claude, local Ollama) and GitHub Copilot extensions, allowing AI assistants to autonomously perform database operations through a standardized protocol.
