qwen-devtools-mcp

All-in-one local MCP server for coding agents. It runs over stdio and intentionally has no npm dependencies.

Run

npm start

Point your MCP client at:

{
  "mcpServers": {
    "qwen-devtools": {
      "command": "node",
      "args": ["C:/qwentestmcp/src/index.js"],
      "env": {
        "QWEN_MCP_WORKSPACE": "C:/qwentestmcp"
      }
    }
  }
}

Tool Surface

• Parallel inspection: parallel_tool_calling
• Python: python_info, python_run, python_script_run
• Local execution: powershell_run, shell_run
• Filesystem: read, read many, write, append, exact replace, list, tree, stat, exists, mkdir, copy, move, delete, file search, text search
• Git: git_status, git_diff, git_log
• Planning: plan_create, plan_get, plan_update_step, plan_add_step, plan_clear
• Sequential thinking: sequential_thinking, sequential_thinking_get, sequential_thinking_clear
• Network: http_fetch
• Data utilities: JSON format/query, word count, Base64, hashes, UUIDs, simple line diff, regex tests, timestamp, env inspection

parallel_tool_calling is intentionally read-only. Use it to batch independent file reads, searches, directory listings, git inspection, and pure data utilities. It rejects write/delete/process-execution tools.

Prompt

The Qwen coding-agent prompt is in prompts/qwen-coding-agent.md and is also exposed as the MCP prompt qwen_coding_agent.

Safety

This server exposes powerful local tools, including process execution and filesystem writes/deletes. Use it only with trusted MCP clients and trusted prompts.
