get_console_logs

Instructions

Implementation Reference

• src/tools/devtools-console.ts:16-27 (handler)

  The handler function for the 'get_console_logs' tool. Sends a command via WebSocket bridge to the Chrome extension to retrieve console messages, with optional filtering by level and clearing after read.

  async ({ level, clear, tabId, apiKey }) => {
    const result = await bridge.sendCommand({
      command: 'get_console_logs',
      params: { level, clear },
      tabId,
      apiKey,
    });
    if (!result.success) {
      return { content: [{ type: 'text', text: `Error: ${result.error?.message}` }], isError: true };
    }
    return { content: [{ type: 'text', text: JSON.stringify(result.data, null, 2) }] };
  }

• src/tools/devtools-console.ts:9-15 (schema)

  Zod schema defining the input parameters for 'get_console_logs': level (enum filter), clear (boolean flag), tabId, and apiKey (all optional).

  {
    level: z.enum(['log', 'warn', 'error', 'info', 'debug', 'all']).optional()
      .describe('Filter logs: "error" for errors only, "warn" for warnings, "all" for everything (default)'),
    clear: z.boolean().optional().describe('Clear all logs after reading so you only get new messages next time'),
    tabId: z.number().optional().describe('Target tab ID (defaults to active tab)'),
    apiKey: z.string().optional().describe('API key for authentication if enabled'),
  },

• src/tools/devtools-console.ts:6-28 (registration)

  Registration of the 'get_console_logs' tool via server.tool() in the registerDevtoolsConsoleTools function. Called from registerAllTools in tools/index.ts.

  server.tool(
    'get_console_logs',
    'Get all console messages from the page (console.log, console.error, warnings, etc.). Use this to debug JavaScript errors, see what the page is logging, or verify your code is running.',
    {
      level: z.enum(['log', 'warn', 'error', 'info', 'debug', 'all']).optional()
        .describe('Filter logs: "error" for errors only, "warn" for warnings, "all" for everything (default)'),
      clear: z.boolean().optional().describe('Clear all logs after reading so you only get new messages next time'),
      tabId: z.number().optional().describe('Target tab ID (defaults to active tab)'),
      apiKey: z.string().optional().describe('API key for authentication if enabled'),
    },
    async ({ level, clear, tabId, apiKey }) => {
      const result = await bridge.sendCommand({
        command: 'get_console_logs',
        params: { level, clear },
        tabId,
        apiKey,
      });
      if (!result.success) {
        return { content: [{ type: 'text', text: `Error: ${result.error?.message}` }], isError: true };
      }
      return { content: [{ type: 'text', text: JSON.stringify(result.data, null, 2) }] };
    }
  );

• src/websocket-bridge.ts:63-103 (helper)

  The sendCommand method on WebSocketBridge that the handler calls. Sends the 'get_console_logs' command over WebSocket to the Chrome extension and returns the response.

  async sendCommand(cmd: BridgeCommand): Promise<BridgeResponse> {
    if (!this.isConnected()) {
      return {
        success: false,
        error: {
          code: 'NOT_CONNECTED',
          message: 'Chrome extension is not connected. Ensure the extension is installed, enabled, and the browser is running.',
        },
      };
    }
  
    const id = crypto.randomUUID();
    const timeout = cmd.timeout ?? DEFAULT_TIMEOUT;
  
    return new Promise<BridgeResponse>((resolve, reject) => {
      const timer = setTimeout(() => {
        this.pending.delete(id);
        resolve({
          success: false,
          error: {
            code: 'TIMEOUT',
            message: `Command '${cmd.command}' timed out after ${timeout}ms`,
          },
        });
      }, timeout);
  
      this.pending.set(id, { resolve, reject, timer });
  
      const message = {
        id,
        type: 'request',
        command: cmd.command,
        params: cmd.params,
        tabId: cmd.tabId,
        apiKey: cmd.apiKey,
        timestamp: Date.now(),
      };
  
      this.client!.send(JSON.stringify(message));
    });
  }
