memorize · Manasdb MCP: Risk & Policy

WHAT IT DOES

What memorize does on Manasdb

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

WHY IT NEEDS A POLICY

Why memorize needs a policy

The tool creates/writes new memory entries into a persistent memory store. It does not delete or execute code; it is a reversible write operation (memories can be forgotten via the sibling 'forget' tool). Medium severity because an AI agent could store sensitive or misleading information persistently across sessions.

From the tool's definition "Absorb and store new information into ManasDB memory"

Verdict

memorize Rate-limited

memorize 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Manasdb, so you can run agents against it safely.

FAQ

Questions about memorize

What does the memorize tool do? +

Absorb and store new information into ManasDB memory. It is categorised as a Write tool in the Manasdb MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on memorize? +

Register the Manasdb MCP server in PolicyLayer and add a rule for memorize: 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 Manasdb. Nothing to install.

What risk level is memorize? +

memorize is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit memorize? +

Yes. Add a rate_limit block to the memorize 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.

How do I block memorize completely? +
