write_to_memory · Pokemon MCP Server MCP: Risk & Policy

WHAT IT DOES

What write_to_memory does on Pokemon MCP Server

AI agents use write_to_memory 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 write_to_memory needs a policy

The name 'write_to_memory' strongly suggests it modifies game memory state, which is a Write operation at minimum. However, writing arbitrary values to memory could be destructive (corrupting game state irreversibly) or even Execute-level if it allows arbitrary code execution via memory manipulation. Given the gaming context and sibling tools like 'read_from_memory', this is likely game memory manipulation.

From the tool's definition Tool name 'write_to_memory' implies writing/modifying data in memory; description is empty and uninformative.
