save_state · Pokemon MCP Server MCP: Risk & Policy

WHAT IT DOES

What save_state does on Pokemon MCP Server

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

WHY IT NEEDS A POLICY

Why save_state needs a policy

This tool creates or modifies game state data in a reversible manner (saved states can be overwritten or loaded from). It does not execute arbitrary commands, delete data irreversibly, or affect external systems. The blast radius is limited to the game session state, making it a Write-category risk with low severity since the operation is recoverable and scoped to game data only.

From the tool's definition Tool name 'save_state' and description 'Saves the current state of the game' indicate a write operation that modifies persisted game state.

Verdict

save_state Rate-limited

save_state 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.
