List the user's recorded browser sessions, newest first — the entry point for the get_session_* and DOM tools. Returns compact JSON rows ({ sessionId, origin, url, title, startedAt, ... }); free-text fields are clipped (origin 100, url 300, title 200 chars). If the MCP client scoped roots to specific origins and no origin filter is given, results are restricted to the client's scoped origins. Start here to obtain a sessionId, then call get_session_summary.

Get an LLM-readable narrative summary of one session: pages visited, click/input/navigation counts, and error counts. Use this first for an overview before drilling into get_session_console_errors / get_session_network_errors. Returns a structured JSON summary.

List console error messages recorded in a session, oldest first. Each row has a numeric id to pass to get_user_action_before_error. Returns JSON rows ({ id, ts, level, message, stack }); message clipped to 500 and stack to 800 chars. For error counts at a glance, use get_session_summary first.

List failed or notable network requests in a session (HTTP status >= statusGte, or a transport-level network error), oldest first. Returns JSON rows ({ id, ts, method, url, status, statusText, resourceType, durationMs, errorText }); url and errorText clipped to 300 chars.

Reconstruct what the user did right before a console error: returns the last window user actions (click/type/navigate) preceding the error, to explain how it was triggered. Returns JSON { errorId, errorTs, actions }. Get errorId from get_session_console_errors first.

Generate a runnable Playwright test (TypeScript) reproducing the user actions in a session: clicks, typing, navigation, and changes. Optionally limit to a [startTs, endTs] epoch-ms window. Returns the test source as text. Note: only single-value is represented (rrweb captures one value per input).

Reconstruct the page DOM as it existed at a timestamp (or a selector subtree within it) and return it as HTML. Applies structural/attribute/text mutations on top of the nearest full snapshot at or before ts. Returns JSON { baseSnapshotTs, mutationsApplied, html }; html clipped to 24000 chars. Fails if no full snapshot exists at or before ts.

Timeline of attribute and/or text changes over a session for the node matching a CSS selector - useful for tracking how one element evolved. Returns JSON { selector, changes }. Use op to restrict to attribute changes or innerText; omit for both.

Ask the user to authorize a browser action via the side-panel banner (Level-3 act-with-confirm). On Allow, returns a one-shot confirmToken to pass to execute_action; on Deny, returns the denial. Every call - allowed or denied - is recorded to ~/.peek/audit.log. Use before execute_action when the origin is at permission Level 3, or to pre-authorize.

Execute an action (click/type/navigate/...) in the user's live browser. Requires per-origin permission Level 3+: Level 3 raises a confirm banner unless a valid confirmToken from request_authorization is passed; Level 4 auto-allows non-destructive actions; Level <3 denies. The destructive-action override (delete/remove/transfer/send/pay/purchase/buy/confirm/subscribe/logout/sign out/unsubscribe/cancel subscription/wire/withdraw) always prompts, even at Level 4. Every call is recorded to ~/.peek/audit.log.
