record_insight · Astria-Index MCP: Risk & Policy

WHAT IT DOES

What record_insight does on Astria-Index

AI agents use record_insight to create or update resources in Astria-Index — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Astria-Index environment.

WHY IT NEEDS A POLICY

Why record_insight needs a policy

The tool creates or modifies persistent data (insights/memories) in an AI memory system. This is a Write operation—it stores information that can be retrieved and presumably modified later. Severity is medium because malicious insights could poison the AI's decision-making across sessions, though the impact is bounded by the system's scope.

From the tool's definition Tool named 'record_insight' with empty description. Based on naming convention and sibling tools (get_note, list_memories, my_insights, promote_session), this appears to be part of a memory/note-taking system.

record_insight Rate-limited

record_insight 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.
