inspect_networkDump
Read-only
Debug API calls by dumping captured network logs. Filter traffic by URL substring and optionally include JSON response bodies to analyze complete request data and diagnose issues.
Instructions
Dump captured network log. Pass bodies:true to include response bodies (JSON APIs). Waits up to 3s for pending body fetches.

Implementation Reference
- extension/background.js:624-644 (handler)The main handler for 'inspect.networkDump' tool. It retrieves captured network entries from the networkCaptures map, filters by URL if specified, optionally fetches response bodies via CDP Network.getResponseBody, and returns the captured network entries.
case 'inspect.networkDump': { const capture = networkCaptures.get(tabId) if (!capture) return { entries: [] } // Wait briefly for in-flight requests to complete await new Promise(r => setTimeout(r, Math.min(params.wait_ms || 500, 3000))) const entries = capture.entries.filter(e => { if (params.url_filter && !e.url?.includes(params.url_filter)) return false return true }) // Optionally fetch response bodies if (params.bodies) { for (const entry of entries) { if (!entry.requestId || entry.responseBody !== undefined) continue try { const body = await chrome.debugger.sendCommand({ tabId }, 'Network.getResponseBody', { requestId: entry.requestId }) entry.responseBody = body?.body?.substring(0, 10000) || '' } catch { /* body not available */ } } } return { count: entries.length, entries } } - extension/background.js:318-320 (registration)Tool capability registration where 'inspect.networkDump' is listed as a supported tool in the capabilities response.

Filters for API-like requests (JSON, XML) and stores them in the networkCaptures map for later retrieval by inspect.networkDump.
