WHAT IT DOES

What selection_grow does on Mcp Anything

AI agents use selection_grow to create or update resources in Mcp Anything, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Anything environment.

RISK

Why selection_grow is rated Medium

This tool modifies the current selection state (grows it) in what appears to be a graphics/animation application. It changes the selection boundary but does not delete data, execute arbitrary code, or move money. Selection changes are reversible, making Write the appropriate category. Severity is low as misuse only affects the selection state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs selection_grow safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Anything, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For selection_grow, this is the rule to start with:

selection_grow Rate-limited

selection_grow stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
