DAP-MCP

What it does

DAP MCP connects an AI assistant to a debugger via the Debug Adapter Protocol (DAP). It enables LLMs to actively participate in the debugging process by interacting directly with the debugger to inspect state, manage execution, and analyze code behavior in real-time.

Tools

• launch: Starts the debuggee program.
• set_breakpoint: Adds a breakpoint at a specific file and line.
• remove_breakpoint: Clears a specified breakpoint.
• list_all_breakpoints: Retrieves all active breakpoints.
• continue_execution: Resumes program execution until the next breakpoint.
• step_in: Enters a function call.
• step_out: Exits the current function.
• next: Steps over to the following line of code.
• evaluate: Evaluates an expression in the current context.
• change_frame: Switches between stack frames.
• view_file_around_line: Displays source code around a specific line.
• terminate: Ends the debugging session.
