Implementation Reference
- qwen3-mcp-server.js:184-193 (handler)The specific handler logic for the 'qwen3_code_explain' tool. It constructs a detailed prompt for code explanation and invokes the shared callQwen3Coder helper function to query the Qwen3-Coder model.
case "qwen3_code_explain": prompt = `Please explain the following ${args.language || 'code'} in detail, including what it does, how it works, and any important concepts: \`\`\`${args.language || ''} ${args.code} \`\`\` Provide a clear and comprehensive explanation.`; result = await callQwen3Coder(prompt); break; - qwen3-mcp-server.js:81-97 (registration)Registration of the 'qwen3_code_explain' tool in the ListTools response, including its name, description, and input schema.
name: "qwen3_code_explain", description: "Explain code using Qwen3-Coder", inputSchema: { type: "object", properties: { code: { type: "string", description: "The code to explain" }, language: { type: "string", description: "Programming language of the code" } }, required: ["code"] } }, - qwen3-mcp-server.js:83-96 (schema)Input schema definition for the 'qwen3_code_explain' tool, specifying required 'code' parameter and optional 'language'.
inputSchema: { type: "object", properties: { code: { type: "string", description: "The code to explain" }, language: { type: "string", description: "Programming language of the code" } }, required: ["code"] } - qwen3-mcp-server.js:25-56 (helper)Shared helper function used by all Qwen3 tools to spawn an Ollama process running the 'qwen3-coder:30b' model with the constructed prompt, capturing output with timeout handling.
async function callQwen3Coder(prompt, options = {}) { return new Promise((resolve, reject) => { const ollamaProcess = spawn('ollama', ['run', 'qwen3-coder:30b', prompt], { stdio: ['pipe', 'pipe', 'pipe'] }); let output = ''; let error = ''; ollamaProcess.stdout.on('data', (data) => { output += data.toString(); }); ollamaProcess.stderr.on('data', (data) => { error += data.toString(); }); ollamaProcess.on('close', (code) => { if (code === 0) { resolve(output.trim()); } else { reject(new Error(`Ollama process exited with code ${code}: ${error}`)); } }); // Set timeout for long-running requests setTimeout(() => { ollamaProcess.kill(); reject(new Error('Request timeout')); }, options.timeout || 120000); // 2 minutes default timeout }); }
