get_note
AI agents call get_note 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.
The tool appears to retrieve or fetch a note from the memory system, consistent with Read operations (no side effects, no data modification or deletion). The empty description limits confidence slightly, but the tool name and server context provide sufficient evidence for a Read classification. Low severity because retrieval alone poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'get_note' suggests retrieval of stored information. The server context (Astria-Index as an AI memory system) and sibling tools like 'recall', 'list_memories', and 'my_insights' indicate this is part of a data retrieval interface.
Attacks that exploit this kind of access
get_note. 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 get_note: 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.
get_note 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 get_note 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 get_note. 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.
get_note 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.
