Why link_memories is rated Medium
Based on the tool name 'link_memories', it likely creates associations or links between existing memory entries, which is a reversible write operation. The server context ('Auditable memory and governance for AI agents') supports this interpretation. Confidence is low due to the empty description, but 'link' strongly implies creating a relationship rather than reading, executing, or deleting.
From the tool's definition Tool name: 'link_memories'; description is empty/uninformative.
Attacks that exploit this kind of access
The rule that runs link_memories 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 link_memories, this is the rule to start with:
link_memories 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Mapi Agent Memory, apply this rule, and every link_memories call is checked against it from then on.
