# crow_browser_capture_har Start or stop HAR (HTTP Archive) recording to capture all network requests. Useful for API discovery. Agent View of the PolicyLayer registry record for `crow_browser_capture_har`. HTML page: https://policylayer.com/tools/kh0pper-crow/crow-browser-capture-har ## Facts - Tool: `crow_browser_capture_har` - Server: Crow (`kh0pper/crow`) — https://policylayer.com/tools/kh0pper-crow.md - Homepage: https://github.com/kh0pper/crow - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "crow_browser_capture_har", "arguments": {} } } ``` ## Why crow_browser_capture_har is rated High This tool initiates or terminates a browser-level network capture session, which is an active external operation (not a passive read). It intercepts all network requests and could expose sensitive data (auth tokens, credentials, API keys) from captured traffic. The 'useful for API discovery' note further indicates it is probing/surveillance in nature. From the tool's own definition: "'Start or stop HAR (HTTP Archive) recording to capture all network requests' — triggers an active recording/monitoring operation in the browser that intercepts network traffic" ## Use case AI agents invoke crow_browser_capture_har to trigger actions in Crow. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
