What store_episodic_memory does on Metis Public Health
AI agents use store_episodic_memory to create or update resources in Metis Public Health, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Metis Public Health environment.
Why store_episodic_memory is rated Medium
The name suggests storing (writing) episodic memory entries to the local-first data store. This aligns with Write category based on sibling tools like 'add_memory_entry' and 'add_journal_entry' which also write data. Empty description lowers confidence. Severity is medium as it could write arbitrary data to the user's memory store, but is local-first with limited blast radius.
From the tool's definition Tool name 'store_episodic_memory' implies writing/persisting data; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs store_episodic_memory safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Metis Public Health, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For store_episodic_memory, this is the rule to start with:
store_episodic_memory 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Metis Public Health, apply this rule, and every store_episodic_memory call is checked against it from then on.
