Implementation Reference
- src/server/tools/ModeTools.ts:136-185 (handler)The main handler function that implements the process_umb_command tool logic: validates memory bank, checks UMB trigger in command, activates UMB mode if valid.
export function handleProcessUmbCommand(memoryBankManager: MemoryBankManager, command: string) { if (!memoryBankManager.getMemoryBankDir()) { return { content: [ { type: 'text', text: 'Memory Bank not found. Use initialize_memory_bank to create one.', }, ], isError: true, }; } const isUmbTrigger = memoryBankManager.checkUmbTrigger(command); if (!isUmbTrigger) { return { content: [ { type: 'text', text: 'Invalid UMB command. Use "Update Memory Bank" or "UMB".', }, ], isError: true, }; } const success = memoryBankManager.activateUmbMode(); if (!success) { return { content: [ { type: 'text', text: 'Failed to activate UMB mode. Check if the current mode supports UMB.', }, ], isError: true, }; } return { content: [ { type: 'text', text: '[MEMORY BANK: UPDATING] UMB mode activated. You can temporarily update Memory Bank files.', }, ], }; } - src/server/tools/ModeTools.ts:29-42 (schema)Tool schema definition including name, description, and input schema requiring a 'command' string.
{ name: 'process_umb_command', description: 'Processes the Update Memory Bank (UMB) command', inputSchema: { type: 'object', properties: { command: { type: 'string', description: 'Complete UMB command', }, }, required: ['command'], }, }, - src/server/tools/index.ts:30-38 (registration)Registers the tool for discovery by including it in the modeTools array within the list of all tools handled by ListToolsRequestSchema.
server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools: [ ...coreTools, ...progressTools, ...contextTools, ...decisionTools, ...modeTools, ], })); - src/server/tools/index.ts:265-271 (registration)Dispatches calls to the process_umb_command tool by extracting arguments and invoking the handleProcessUmbCommand handler in the main tool call switch statement.
