What store_semantic_memory does on Metis Public Health
AI agents use store_semantic_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_semantic_memory is rated Medium
The name strongly suggests this tool writes semantic memory entries to some persistent store. Based on sibling tools like 'add_memory_entry', this fits the Write category — creating or modifying data reversibly. No description is available to confirm or refine this, so confidence is reduced. Severity is medium since storing incorrect or malicious memory entries could influence future AI responses.
From the tool's definition Tool name 'store_semantic_memory' implies writing/storing data; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs store_semantic_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_semantic_memory, this is the rule to start with:
store_semantic_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_semantic_memory call is checked against it from then on.
