Implementation Reference
- src/core/MCPServer.ts:223-229 (handler)The handler for the 'update_record' tool. Validates input using UpdateRecordArgsSchema and calls this.dataService.updateRecord to perform the update.
case 'update_record': { return await safeExecute(toolName, async () => { const args = validateInput(UpdateRecordArgsSchema, request.params.arguments); const record = await this.dataService.updateRecord(args.resourceUri, args.recordId, args.data); return record; }); } - src/core/MCPServer.ts:154-157 (registration)Registration of the 'update_record' tool in the list_tools handler, including name, description, and input schema reference.
name: 'update_record', description: 'Update a record in a resource', inputSchema: getInputSchema(UpdateRecordArgsSchema), }, - src/types/index.ts:87-91 (schema)Zod schema defining the input arguments for the update_record tool: resourceUri, recordId, and data.
export const UpdateRecordArgsSchema = z.object({ resourceUri: z.string().describe('URI of the resource'), recordId: z.string().describe('ID of the record to update'), data: z.record(z.unknown()).describe('New record data'), }); - Implementation of the updateRecord method in the InMemoryDataService, which is called by the tool handler to perform the actual record update in memory.
public async updateRecord( uri: string, id: string, data: Record<string, unknown> ): Promise<Record<string, unknown>> { this.validateResource(uri); const resourceData = this.data.get(uri)!; const existingRecord = resourceData.get(id); if (!existingRecord) { throw new Error(`Record not found: ${id}`); } const updatedRecord = { ...existingRecord, ...data, id, // Ensure ID doesn't change updatedAt: new Date().toISOString() }; resourceData.set(id, updatedRecord); return updatedRecord; }
