Implementation Reference
- server.js:248-263 (handler)The `pullModel` function is the handler for the `pull_model` tool. It validates the required 'name' argument, sends an HTTP POST request to Ollama's /api/pull endpoint with stream:false, and returns the model name, status, and success flag.
async function pullModel(args) { const bad = requireString(args, 'name'); if (bad) return errorResult(bad); // Use stream:false — Ollama buffers and returns a single final event. // For very large models this can block the connection for a long time; // users pulling multi-GB models are better served by `ollama pull` in a // terminal where they can see progress. Documented in the README. const r = await httpRequest('POST', '/api/pull', { name: args.name, stream: false }); if (r.error) return errorResult(r.error); const d = r.data || {}; return textResult({ name: args.name, status: d.status || 'unknown', success: d.status === 'success', }); } - server.js:357-368 (schema)Tool definition/schema for 'pull_model'. Includes name, description, annotations (title: 'Pull model'), and inputSchema requiring a 'name' string (e.g. 'llama3.1:8b').
