Implementation Reference

• src/server/tools/CoreTools.ts:469-546 (handler)

  The handler function that executes the debug_mcp_config tool, gathering and returning detailed MCP configuration information including memory bank status, mode info, and system details.

  export async function handleDebugMcpConfig(
    memoryBankManager: MemoryBankManager,
    verbose: boolean = false
  ) {
    try {
      // Get basic information
      const memoryBankDir = memoryBankManager.getMemoryBankDir();
      const projectPath = memoryBankManager.getProjectPath();
      const language = memoryBankManager.getLanguage();
      const folderName = memoryBankManager.getFolderName();
      
      // Get mode information
      const modeManager = memoryBankManager.getModeManager();
      let modeInfo = null;
      if (modeManager) {
        const currentModeState = modeManager.getCurrentModeState();
        modeInfo = {
          name: currentModeState.name,
          isUmbActive: currentModeState.isUmbActive,
          memoryBankStatus: currentModeState.memoryBankStatus
        };
      }
      
      // Get Memory Bank status
      let memoryBankStatus = null;
      try {
        if (memoryBankDir) {
          memoryBankStatus = await memoryBankManager.getStatus();
        }
      } catch (error) {
        console.error('Error getting Memory Bank status:', error);
      }
      
      // Get system information
      const systemInfo = {
        platform: os.platform(),
        release: os.release(),
        arch: os.arch(),
        nodeVersion: process.version,
        cwd: process.cwd(),
        env: verbose ? process.env : undefined
      };
      
      // Collect all information
      const debugInfo = {
        timestamp: new Date().toISOString(),
        memoryBank: {
          directory: memoryBankDir,
          projectPath,
          language,
          folderName,
          status: memoryBankStatus
        },
        mode: modeInfo,
        system: systemInfo
      };
      
      return {
        content: [
          {
            type: "text",
            text: `MCP Configuration Debug Information:\n${JSON.stringify(debugInfo, null, 2)}`,
          },
        ],
      };
    } catch (error) {
      console.error("Error in handleDebugMcpConfig:", error);
      return {
        content: [
          {
            type: "text",
            text: `Error debugging MCP configuration: ${error}`,
          },
        ],
        isError: true
      };
    }
  }

• src/server/tools/CoreTools.ts:39-53 (schema)

  The input schema and tool definition for debug_mcp_config, part of the coreTools array used for tool registration and validation.

  {
    name: 'debug_mcp_config',
    description: 'Debug the current MCP configuration',
    inputSchema: {
      type: 'object',
      properties: {
        verbose: {
          type: 'boolean',
          description: 'Whether to include detailed information',
          default: false,
        },
      },
      required: [],
    },
  },

• src/server/tools/index.ts:79-82 (registration)

  The switch case in the tool call handler that registers and routes 'debug_mcp_config' requests to the handleDebugMcpConfig function.

  case 'debug_mcp_config': {
    const { verbose } = request.params.arguments as { verbose?: boolean };
    return handleDebugMcpConfig(memoryBankManager, verbose || false);
  }
