memory_verify · Verifiedstate MCP: Risk & Policy

WHAT IT DOES

What memory_verify does on Verifiedstate

AI agents invoke memory_verify to trigger actions in Verifiedstate. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why memory_verify needs a policy

This tool actively executes a verification process and has side effects: it produces a signed receipt and mutates the assertion's status. It's not a pure read (data is modified/created) and not destructive or financial. 'Updates assertion status' and 'produces a signed receipt' indicate write-like side effects triggered by an execution pipeline, making Execute the most appropriate category.

From the tool's definition 'Run the verification ladder on an assertion. Produces a signed receipt and updates assertion status.'

Verdict

memory_verify Rate-limited

memory_verify stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
