Open-Source Qwen-DAP-MCP Lets Local Coding Agents Actually Run and Debug Code
Additional_Reach2545 · reddit · 2026-08-27
A developer released qwen-dap-mcp, an open-source MCP server bridging local Qwen models with the Debug Adapter Protocol so coding agents can run, debug and step through code rather than just generate snippets.
Key features:
- Exposes Qwen (via llama.cpp local server) as an MCP tool provider
- The model can launch debug sessions, set breakpoints, step/continue, inspect variables, and evaluate expressions in the running context
- Fully local and privacy-preserving, with no cloud calls; works with MCP clients like Qwen Code and Claude Code
The stack is a TypeScript/Node MCP server plus a DAP client talking to standard debug adapters (Python, Node, etc.). The author is soliciting feedback on architecture and whether to add a more opinionated agent workflow.
