What preview_project_memory_retention does on Mapi Agent Memory
AI agents call preview_project_memory_retention to retrieve information from Mapi Agent Memory without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why preview_project_memory_retention is rated Low
The tool only builds a preview of memory retention for a project namespace. It is explicitly described as read-only and deterministic, meaning it queries/computes data without modifying, deleting, or executing anything. Misuse potential is low since no state is changed.
From the tool's definition "deterministic read-only retention preview" — explicitly stated as read-only and produces a preview without side effects
Attacks that exploit this kind of access
The rule that runs preview_project_memory_retention 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 preview_project_memory_retention, this is the rule to start with:
preview_project_memory_retention is read-only, so it stays allowed. 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 preview_project_memory_retention call is checked against it from then on.
Questions about preview_project_memory_retention
Build a deterministic read-only retention preview for one project namespace. It is categorised as a Read tool in the Mapi Agent Memory MCP Server, which means it retrieves data without modifying state.
Register the Mapi Agent Memory MCP server in PolicyLayer and add a rule for preview_project_memory_retention: 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.
preview_project_memory_retention is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the preview_project_memory_retention 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.
Set action: deny in the PolicyLayer policy for preview_project_memory_retention. 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.
preview_project_memory_retention 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.
