Memory Box MCP Server

Instructions

Implementation Reference

• src/index.ts:1239-1255 (handler)

  MCP CallToolRequest handler case for 'delete_memory': validates memory_id parameter and calls memoryBoxClient.deleteMemory, returning success message.
  case "delete_memory": { const memoryId = request.params.arguments?.memory_id; if (!memoryId) { throw new McpError(ErrorCode.InvalidParams, "Memory ID is required"); } // Delete the memory const result = await memoryBoxClient.deleteMemory(Number(memoryId)); return { content: [{ type: "text", text: `Memory ${memoryId} deleted successfully!\n\n${result.message || "The memory has been permanently removed."}` }] }; }
• src/index.ts:498-518 (handler)

  MemoryBoxClient.deleteMemory method: performs the actual HTTP DELETE request to the Memory Box API endpoint /api/v2/memory/{memoryId}.
  async deleteMemory(memoryId: number): Promise<any> { try { const response = await axios.delete( `${this.baseUrl}/api/v2/memory/${memoryId}`, { headers: { "Authorization": `Bearer ${this.token}` } } ); return response.data; } catch (error) { if (axios.isAxiosError(error)) { throw new McpError( ErrorCode.InternalError, `Failed to delete memory: ${error.response?.data?.detail || error.message}` ); } throw error; } }
• src/index.ts:850-863 (schema)

  Tool schema registration in ListTools response: defines name, description, and inputSchema requiring integer memory_id.
  { name: "delete_memory", description: "Delete a specific memory", inputSchema: { type: "object", properties: { memory_id: { type: "integer", description: "The ID of the memory to delete" } }, required: ["memory_id"] } }
• src/index.ts:543-866 (registration)
