Rails MCP Server 1.5.0: Hardened Security & Sandbox Support

When you give an AI model access to your codebase through MCP tools, security is paramount. That's why version 1.5.0 introduces rigorous input validation for file-accessing analyzers, building on our existing execute_ruby sandbox protections.

We also addressed a major friction point for modern AI workflows: Sandboxed Environments. Agents like GitHub Copilot and Claude Code often run in restricted containers without access to a home directory. Our new --single-project flag solves this by skipping global config files and focusing entirely on the current working directory.
