Implementation Reference
- src/index.ts:928-958 (handler)MCP tool handler for 'get-workflow': validates clientId, retrieves N8nClient instance, calls client.getWorkflow(id), and returns the workflow JSON or error.
case "get-workflow": { const { clientId, id } = args as { clientId: string; id: string }; const client = clients.get(clientId); if (!client) { return { content: [{ type: "text", text: "Client not initialized. Please run init-n8n first.", }], isError: true }; } try { const workflow = await client.getWorkflow(id); return { content: [{ type: "text", text: JSON.stringify(workflow, null, 2), }] }; } catch (error) { return { content: [{ type: "text", text: error instanceof Error ? error.message : "Unknown error occurred", }], isError: true }; } } - src/index.ts:424-434 (registration)Tool registration in ListTools response, defining name, description, and input schema for 'get-workflow'.
