Browser Intelligence · Browser DevTools

Browser DevTools for structured inspection workflows.

A capability under SiteLens Browser Intelligence—live sessions with redacted console/network capture, response bodies, and deterministic diagnostics. SiteLens combines browser automation, observability, diagnostics, visual regression, and evidence into one coherent workflow.

Hierarchy

Browser DevTools is the inspection surface many developers search for—console, network, payloads, bodies, diagnostics. Cross-run comparison, unified timeline, visual regression, reports, and hosted execution live at the Browser Intelligence level. Prefer SiteLens session tools for typical QA/debugging MCP workflows; keep raw CDP only for surfaces SiteLens does not model.

Observability & debugging

Shipped

Console & page errors

Filterable console messages and uncaught page errors with sequence cursors—live session or persisted localRunId.

Network & payloads

List exchanges, match query strings, inspect headers/timing, pull policy-gated response bodies without re-fetching.

Diagnostics

Deterministic engine ranks findings with evidence refs; explain failed steps with correlated browser events.

Assertions & waits

Assert already-captured events; wait for console/network with lookback so fast triggers do not race the waiter.

Example workflows

Agents & developers

Failed login

sitelens_session_start → run login steps → console/network → sitelens_run_diagnostics → evidence.

API failure / 401 chain

sitelens_get_network_requests → sitelens_inspect_network → sitelens_get_response_body.

Assertion explain

sitelens_explain_step_failure correlates the failed step with console/network/diagnostics.

Compare green vs red

Use sitelens_compare_browser_runs and timeline tools from the broader Browser Intelligence surface.

Session workflow

Start

sitelens_session_start with captureMode: "standard".

Drive

sitelens_session_run_steps — same vocabulary as project flows.

Inspect

Console, network, bodies, diagnostics.

Close

sitelens_session_close — export artifacts when investigating.
