• src/index.ts:1227-1257 (handler)

  Handler function in the CallToolRequestSchema that executes the update-project tool by calling N8nClient.updateProject
  case "update-project": { const { clientId, projectId, name } = args as { clientId: string; projectId: string; name: string }; const client = clients.get(clientId); if (!client) { return { content: [{ type: "text", text: "Client not initialized. Please run init-n8n first.", }], isError: true }; } try { await client.updateProject(projectId, name); return { content: [{ type: "text", text: `Successfully updated project ${projectId} with new name: ${name}`, }] }; } catch (error) { return { content: [{ type: "text", text: error instanceof Error ? error.message : "Unknown error occurred", }], isError: true }; } }
• src/index.ts:543-554 (schema)

  Input schema definition for the update-project tool in the tools list returned by ListToolsRequestSchema
  name: "update-project", description: "Update a project's name. NOTE: Requires n8n Enterprise license with project management features enabled. IMPORTANT: Arguments must be provided as compact, single-line JSON without whitespace or newlines.", inputSchema: { type: "object", properties: { clientId: { type: "string" }, projectId: { type: "string" }, name: { type: "string" } }, required: ["clientId", "projectId", "name"] } },
• src/index.ts:543-554 (registration)
