Implementation Reference
- src/memory-manager.js:931-944 (handler)The core handler function that executes the tool logic by querying the memoryChanges table for the change history of the specified memory ID and returns the ordered list of changes.
async getMemoryHistory(memoryId) { try { const history = await this.db .select() .from(schema.memoryChanges) .where(eq(schema.memoryChanges.memoryId, memoryId)) .orderBy(desc(schema.memoryChanges.changedAt)); return history; } catch (error) { console.warn('Memory history query failed:', error.message); return []; } } - mcp.js:674-676 (registration)The registration and dispatch point in the MCP server where tool calls to 'get_memory_history' are handled by invoking the MemoryManager's getMemoryHistory method.
case "get_memory_history": const memoryHistory = await memoryManager.getMemoryHistory(args.memory_id); return { content: [{ type: "text", text: JSON.stringify(memoryHistory, null, 2) }] }; - mcp.js:458-470 (schema)The input schema definition for the 'get_memory_history' tool, specifying the required 'memory_id' parameter.
{ name: "get_memory_history", description: "Get change history for a specific memory", inputSchema: { type: "object", properties: { memory_id: { type: "string", description: "UUID of the memory" } }, required: ["memory_id"] } - src/tools/memory-tools.js:432-444 (schema)The schema definition for the tool in the memoryTools export array (possibly for reference or alternative implementation).
