Implementation Reference
- src/tools/tool-handlers.ts:89-98 (handler)The handler function for the 'save_document' tool. It calls documentManager.saveDocument with the provided docId and returns a success message with the saved filepath.
case "save_document": const filepath = await documentManager.saveDocument(args.docId); return { content: [ { type: "text", text: `Document saved successfully to: ${filepath}`, }, ], }; - src/tools/document-tools.ts:172-185 (schema)Input schema definition for the 'save_document' tool, specifying that it requires a 'docId' string parameter.
{ name: "save_document", description: "Save the document to disk", inputSchema: { type: "object", properties: { docId: { type: "string", description: "Document identifier", }, }, required: ["docId"], }, }, - src/index.ts:24-28 (registration)Registers the list of available tools (from documentTools array, which includes 'save_document') with the MCP server for the ListToolsRequest.
server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools: documentTools, }; }); - Core implementation of saving the document: reconstructs the DOCX from in-memory paragraphs using docx library, writes buffer to file, returns filepath.
async saveDocument(docId: string): Promise<string> { const docInfo = this.getDocument(docId); // Recreate document with all paragraphs const document = new Document({ sections: [ { properties: {}, children: docInfo.paragraphs, }, ], }); const buffer = await Packer.toBuffer(document); await fs.writeFile(docInfo.filepath, buffer); return docInfo.filepath; }
