Implementation Reference
- src/tools/devtools-storage.ts:107-120 (handler)The handler for the 'get_session_storage' tool. It reads sessionStorage entries for the current page by sending a 'get_session_storage' command via the WebSocket bridge. Accepts optional 'key' (returns all if omitted), 'tabId' (defaults to active tab), and 'apiKey' params.
server.tool( 'get_session_storage', 'Read sessionStorage entries for the current page', { key: z.string().optional().describe('Specific key to read (returns all if omitted)'), tabId: z.number().optional().describe('Target tab ID (defaults to active tab)'), apiKey: z.string().optional().describe('API key for authentication'), }, async ({ key, tabId, apiKey }) => { const result = await bridge.sendCommand({ command: 'get_session_storage', params: { key }, tabId, apiKey }); if (!result.success) return { content: [{ type: 'text' as const, text: `Error: ${result.error?.message}` }], isError: true }; return { content: [{ type: 'text' as const, text: JSON.stringify(result.data, null, 2) }] }; } ); - Input schema for the 'get_session_storage' tool using Zod. Defines optional 'key' (string), 'tabId' (number), and 'apiKey' (string) parameters with descriptions.
