memory_ingest · Verifiedstate MCP: Risk & Policy

WHAT IT DOES

What memory_ingest does on Verifiedstate

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

WHY IT NEEDS A POLICY

Why memory_ingest needs a policy

The tool creates new data artifacts in a verified memory store. This is a write/create operation - it ingests content and produces persistent artifacts. It does not execute code, delete data, or move money. The severity is medium because AI agents could store incorrect, sensitive, or misleading information into shared memory infrastructure used across multiple sessions and IDEs.

From the tool's definition Ingest raw content (conversation, document, user input) into verified memory. Creates an artifact and evidence spans. Returns artifact_id.
