Implementation Reference
- browser-tools-mcp/mcp-server.ts:196-214 (handler)Handler and registration for the 'getConsoleErrors' MCP tool. Fetches console errors from the discovered browser connector server via HTTP and returns formatted JSON response.
"getConsoleErrors", "Check our browsers console errors", async () => { return await withServerConnection(async () => { const response = await fetch( `http://${discoveredHost}:${discoveredPort}/console-errors` ); const json = await response.json(); return { content: [ { type: "text", text: JSON.stringify(json, null, 2), }, ], }; }); } ); - Helper function used by getConsoleErrors (and other tools) to ensure connection to the browser server before making API calls, with automatic discovery and reconnection logic.
async function withServerConnection<T>( apiCall: () => Promise<T> ): Promise<T | any> { // Attempt to discover server if not already discovered if (!serverDiscovered) { const discovered = await discoverServer(); if (!discovered) { return { content: [ { type: "text", text: "Failed to discover browser connector server. Please ensure it's running.", }, ], isError: true, }; } } // Now make the actual API call with discovered host/port try { return await apiCall(); } catch (error: any) { // If the request fails, try rediscovering the server once console.error( `API call failed: ${error.message}. Attempting rediscovery...` ); serverDiscovered = false; if (await discoverServer()) { console.error("Rediscovery successful. Retrying API call..."); try { // Retry the API call with the newly discovered connection return await apiCall(); } catch (retryError: any) { console.error(`Retry failed: ${retryError.message}`); return { content: [ { type: "text", text: `Error after reconnection attempt: ${retryError.message}`, }, ], isError: true, }; } } else { console.error("Rediscovery failed. Could not reconnect to server."); return { content: [ { type: "text", text: `Failed to reconnect to server: ${error.message}`, }, ], isError: true, }; } } }
