WHAT IT DOES

What apply_memory_relation does on Mapi Agent Memory

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

RISK

Why apply_memory_relation is rated Medium

An AI agent can call apply_memory_relation faster than any human can review: one bad instruction and it creates or modifies resources in Mapi Agent Memory by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs apply_memory_relation safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mapi Agent Memory, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For apply_memory_relation, this is the rule to start with:

apply_memory_relation Rate-limited

apply_memory_relation 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.

FAQ

Questions about apply_memory_relation

What does the apply_memory_relation tool do? +

Apply supports/derived_from only through an evidence-bound guarded contract. It is categorised as a Write tool in the Mapi Agent Memory MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on apply_memory_relation? +

Register the Mapi Agent Memory MCP server in PolicyLayer and add a rule for apply_memory_relation: 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 Mapi Agent Memory. Nothing to install.

What risk level is apply_memory_relation? +

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

Can I rate-limit apply_memory_relation? +

Yes. Add a rate_limit block to the apply_memory_relation 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 apply_memory_relation completely? +

Set action: deny in the PolicyLayer policy for apply_memory_relation. 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.

What MCP server provides apply_memory_relation? +

apply_memory_relation is provided by the Mapi Agent Memory MCP server (cabo0m/mapi-agent-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
