generate_invite · Palate MCP: Risk & Policy

WHAT IT DOES

What generate_invite does on Palate

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

WHY IT NEEDS A POLICY

Why generate_invite needs a policy

This tool creates (writes) a new invite link, which is a reversible action that adds a new record or token to the system. It does not delete, execute arbitrary code, move money, or read existing data. The blast radius is low because invite generation is typically low-risk; the severity depends on subsequent agent behavior, not the invite itself.

From the tool's definition 'Generate an invite link so another agent can join the Palate Network' — the tool creates a new invitation artifact that can be distributed, modifying network state by enabling agent enrollment.

Verdict

generate_invite Rate-limited

generate_invite 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.
