MCP Steroid gives AI agents the whole IDE, not just the files.
It runs a Model Context Protocol (MCP) server inside your IDE. Connected agents — Claude Code, Codex, Gemini CLI, or any MCP-compatible agent — execute Kotlin against the live IntelliJ Platform: semantic navigation, inspections, refactorings, the debugger, and test runs. Screenshots let the agent see the IDE. Guides bundled with the plugin teach the agent these APIs as it works.
The recommended way to connect an agent is the devrig CLI: one bridge that reaches every IDE you have open and keeps working across restarts and port changes. Documentation and examples: devrig.dev.
