Open-source qwen-dap-mcp: gives local Qwen real debugger access via DAP and MCP
Additional_Reach2545 · reddit · 2026-08-26
A developer open-sourced qwen-dap-mcp, a TypeScript MCP server that plugs a local Qwen model (via llama.cpp/GGUF) into MCP clients like Qwen Code or Claude Code, and uses the Debug Adapter Protocol (DAP) to give the model real debugging powers: launch sessions, set/clear breakpoints, step/continue/pause/restart, inspect variables and scopes, and evaluate expressions in the running context.
Motivation: most coding-agent setups either only generate code without executing or debugging it, or rely on hosted APIs. This one is fully local and offline — you can ask it to "debug this failing test" and it attaches a real debugger, steps through, reads variables, and iterates on its own fix.
The author asks for feedback on architecture, missing features, and whether to stay generic or add an opinionated workflow. (Trailing text appears to be leftover AI-generated draft.)
