Implementation Reference
- src/index.ts:553-583 (handler)Handler for executing the 'add_text_file' tool. Validates inputs, calls downloadFile helper to add the text file as a document, and returns success or 'already exists' message.
case "add_text_file": { const fileUrl = String(request.params.arguments?.file_url); const documentName = String(request.params.arguments?.document_name); if (!fileUrl) { throw new Error("File URL is required"); } if (!documentName) { throw new Error("Document name is required"); } const result = await downloadFile(fileUrl, documentName); // If document already exists, inform the user without updating if (result.exists) { return { content: [{ type: "text", text: `Document '${result.name}' already exists. Please use list_documents to view existing documents.` }] }; } return { content: [{ type: "text", text: `Added document '${result.name}' with content from ${fileUrl}. The index will be created when you query this document for the first time.` }] }; } - src/index.ts:411-428 (registration)Registration of the 'add_text_file' tool in the ListToolsRequestSchema handler, defining its name, description, and input schema.
