Use cases

• Automating breakpoint management during debugging sessions
• Controlling step execution from an AI assistant
• Inspecting variables and stack traces programmatically

Pros

• Enables AI assistants to interact directly with the JetBrains debugger
• Leverages the mature debugging infrastructure of JetBrains IDEs
• Open source with a Kotlin codebase for easy customization

Cons

• Requires a JetBrains IDE and an MCP-compatible AI assistant
• Limited to debugger control, not other IDE features
• Small community with 80 stars, so limited support and documentation
