MCP Tool
nova.guarded_login
For risk-bounded actions with visible user control, an agent uses this public tool to handle the sensitive path "Guarded Login". It keeps purpose, scope, user control, and sensitive data handling explicit.
Canonical reference for a public MCP tool name.

Purpose
What this entry explains
What it does
nova.guarded_login
An agent uses this tool to handle the sensitive path "Guarded Login". It belongs to risk-bounded actions with visible user control; 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 "Guarded Login" for risk-bounded actions with visible user control.
- 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 in risk-bounded actions with visible user control can trigger powerful execution and therefore needs target, approval, and result check before the step.
The agent starts with nova.guarded_send_message, reads the current response or reference, and only then chooses the concrete next tool.
Current discovery, target, user control, warning signals, and result check come before execution.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 fields
No fixed public response field is derived from the catalog source for this path. Use current tool discovery and the actual response before chaining the next step.
Safety
Boundary before execution
May touch sensitive data, permissions, credentials, identity, or external connection paths. Use only with explicit scope and visible user control.
Require explicit purpose and current context, avoid exposing secrets in prompts or logs, and stop when permission or identity state is unclear.
For humans, this entry marks the sensitive surface in risk-bounded actions with visible user control and keeps permission, credential, or external-connection handling explicit.
High-Impact Review
Execution boundary and recheck hints
Review category: Auto-apply/mutating flows
Mutating steps may run only with confirmed target, expected effect, user control, and result check.
False assumption: a guard or auto-apply signal replaces current target and result checks.
The user must be able to review action, target, approval, block signal, and visible result.
Execute only the intended step, then verify state and stop on warning, block, or target change.
Recheck if candidate budget, gate, visible state, or expected effect do not line up.
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.
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.high_impact_execution
Runs or prepares JavaScript, CDP, plugin code, auto-apply, or other powerful execution paths.
Explicitly confirm current tool discovery, target, scope, user control, and result check before execution.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.
