MCP Tool
nova.file_upload
For targeted browser interaction with a prechecked target, an agent uses this public tool to handle the sensitive path "File Upload". 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.file_upload
An agent uses this tool to handle the sensitive path "File Upload". It belongs to targeted browser interaction with a prechecked target; 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 "File Upload" for targeted browser interaction with a prechecked target.
- 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 targeted browser interaction with a prechecked target can trigger powerful execution and therefore needs target, approval, and result check before the step.
The agent starts with nova.click_selector, 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
selector
Element selector on the current page. The page needs fresh perception before interaction.
type
Public input field from the catalog source. Confirm the exact schema through current MCP discovery before execution.
filePaths
Public input field from the catalog source. Confirm the exact schema through current MCP discovery before execution.
| Response field | Explanation |
|---|---|
filePaths | Response field named by the catalog source. Treat it as current evidence for the next decision. |
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 targeted browser interaction with a prechecked target and keeps permission, credential, or external-connection handling explicit.
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.
page_interaction
Clicks, types, selects, uploads, or interacts with visible page elements.
Execute only with a visible target, expected effect, and a follow-up result check.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.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.
