MCP Tool

`nova.emulation_clear_media`

For browser environment, window state, and isolated execution surfaces, an agent uses this public tool to handle the sensitive path "Media-Emulation aufheben". It keeps purpose, scope, user control, and sensitive data handling explicit.

Purpose

What this entry explains

What it does

nova.emulation_clear_media An agent uses this tool to handle the sensitive path "Media-Emulation aufheben". It belongs to browser environment, window state, and isolated execution surfaces; agents should combine it with current discovery, target awareness, and the visible result.

Use when

Use this entry when an agent needs to handle the sensitive path "Media-Emulation aufheben" for browser environment, window state, and isolated execution surfaces.
Use it to understand the public tool name, its expected boundary, and the response signals to check.
Use it before chaining follow-up tools so the next step is based on current evidence.

Reference Use

How agents should cite and apply this area

Examples are maintained at family level and use only public tool names or reference paths already present in the catalog.

Family example

A task touches data, identity, or permissions in browser environment, window state, and isolated execution surfaces that may be used only with clear purpose.

The agent starts with nova.emulation_set_device_metrics, reads the current response or reference, and only then chooses the concrete next tool.

nova.emulation_set_device_metrics nova.emulation_set_touch nova.emulation_set_user_agent

Sensitive values stay in current scope; they are not guessed, logged, or copied into other contexts.

Contract

Inputs and important response fields

This page is a public reference. Agents and integrators should still read current MCP tool discovery before execution, because schemas can be gated by settings or version.

Inputs

No stable public input field is derived from the catalog source for this path. Read current MCP discovery before execution.

Response field	Explanation
`media`	Response field named by the catalog source. Treat it as current evidence for the next decision.
`matchMedia`	Response field named by the catalog source. Treat it as current evidence for the next decision.

Safety

Boundary before execution

Effect

May touch sensitive data, permissions, credentials, identity, or external connection paths. Use only with explicit scope and visible user control.

Agent rule

Require explicit purpose and current context, avoid exposing secrets in prompts or logs, and stop when permission or identity state is unclear.

Human control

For humans, this entry marks the sensitive surface in browser environment, window state, and isolated execution surfaces and keeps permission, credential, or external-connection handling explicit.

High-Impact Review

Execution boundary and recheck hints

Review category: Recording/screenshots/media

Execution boundary

Capture only the needed visual or media evidence and respect private content, recording state, and export boundary.

Typical false assumption

False assumption: screenshots or recordings contain only technical evidence.

Visible user control

Recording, screenshot, media access, or export must be visible to the user and purpose-bound.

Agent rule

Before capture, check target, scope, and privacy; use artifacts as evidence only and do not forward them unrequested.

Abort or recheck

Abort if private content is visible, media permission is unclear, or the export contains more than needed.

Safety Axes

How this path can affect work

Axes are stable catalog signals for humans, agents, and LLM discovery. One path can carry several axes.

Browser state browser_state_change

Changes tab, navigation, focus, claim, scroll position, window state, or browser environment.

Confirm the target context visibly before execution and verify that the expected browser state was reached afterwards.

Sensitive sensitive_data

Touches cookies, storage, clipboard, credentials, tokens, user content, identity, or private data.

Use only with bounded purpose and visible user control; do not guess, log, or forward sensitive values.

Recording / media recording_or_media

Creates or reads screenshots, recordings, media, visual evidence, or audio/video signals.

Capture only needed evidence, respect private content, and keep media or recording state visible.

User confirmation user_confirmation

Requires visible confirmation, target review, approval, or deliberate user control.

Do not proceed until the required confirmation is visible or unambiguous in the current context.
