Implementation Reference
- index.js:104-115 (handler)The tool is executed by calling the `callTool` function, which maps the tool name to an endpoint and makes a fetch request to the IteraTools API. The `CallToolRequestSchema` handler in `index.js` acts as the dispatcher for `image_generate` (and all other tools).
const tool = TOOLS.find(t => t.name === name); if (!tool) { return { content: [{ type: 'text', text: `Unknown tool: ${name}` }], isError: true }; } try { const result = await callTool(tool.endpoint, args); return { content: [{ type: 'text', text: JSON.stringify(result, null, 2) }] }; } catch (err) { return { content: [{ type: 'text', text: `Error: ${err.message}` }], isError: true }; } }); - index.js:17-17 (registration)The `image_generate` tool is registered in the `TOOLS` array in `index.js`.
