list_memories
AI agents call list_memories to retrieve information from Astria-Index without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or enumerates memory records without creating, modifying, or deleting data. List operations are non-destructive queries. Even though the description is absent, the name strongly and clearly indicates a data retrieval function typical of memory/note management systems. Confidence is slightly lowered due to missing description, but the tool name is unambiguous.
From the tool's definition Tool name 'list_memories' indicates a retrieval operation that queries stored memory data. The description is empty, but the verb 'list' is a canonical Read operation that retrieves or enumerates data without modification.

list_memories. It is categorised as a Read tool in the Astria-Index MCP Server, which means it retrieves data without modifying state.
Register the Astria-Index MCP server in PolicyLayer and add a rule for list_memories: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Astria-Index. Nothing to install.
list_memories is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_memories rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_memories. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_memories is provided by the Astria-Index MCP server (pl-odin/astria-plugin). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
