mcp-dap-server

Overview

The MCP DAP Server provides a comprehensive interface between AI agents and debuggers through the Debug Adapter Protocol (DAP). It offers tools for session management, breakpoint control, execution flow management, and state inspection. The server handles multiple debugging modes including source code, binary, core dump analysis, and process attachment. With 13 well-documented tools, it enables AI systems to debug code in various programming languages with full programmatic control.

After installing, here are 5 things you can ask your AI assistant:

• debugmode, path, args, coreFilePath, processId, breakpoints, stopOnEntry, port

  Start a debugging session with various modes (source, binary, core, attach)

  Try:Debug the main.go source fileTry:Attach to process with ID 1234Try:Debug myapp binary with arguments ['arg1', 'arg2']
• stop

  End the debugging session

  Try:Stop the debugging sessionTry:Terminate the debuggee
• restartarguments

  Restart the debugging session with optional new arguments

  Try:Restart the debugging sessionTry:Restart with new arguments ['--verbose', '--debug']
• breakpointfile, line, function

  Set a breakpoint at a file:line location or on a function

  Try:Set a breakpoint at main.go:42Try:Set a breakpoint on the main function
• clear-breakpointsfile, all

  Remove breakpoints from a file or clear all breakpoints

  Try:Clear all breakpointsTry:Clear breakpoints in utils.go
• continueto

  Continue program execution, optionally run to a specific location

  Try:Continue executionTry:Run to cursor at main.go:100
• stepmode

  Step through code execution (over, in, or out)

  Try:Step overTry:Step into the functionTry:Step out
• pausethreadId

  Pause program execution on a specific thread

  Try:Pause thread 5Try:Pause the main thread
• contextthreadId, frameId

  Get full debugging context including location, stack trace, and variables

  Try:Show current debugging contextTry:Get stack frame 2's context
• evaluateexpression, frameId, context

FAQ

What programming languages does this server support?

The MCP DAP Server works with any language that has a DAP-compatible debugger. It has been demonstrated with Go debugging through delve, but is designed to work with language-specific debuggers that support the Debug Adapter Protocol.

How does the server handle multiple debugging sessions?

Each debugging tool call creates a new session. The server manages multiple sessions separately, allowing debugging of different processes concurrently.
