WHAT IT DOES

What preview_memory_retention_policy does on Mapi Agent Memory

AI agents call preview_memory_retention_policy 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.

RISK

Why preview_memory_retention_policy is rated Low

The tool generates a deterministic preview of a retention policy for a memory entry. 'Preview' strongly implies a read-only, non-destructive operation that shows what would happen without actually applying any changes. No side effects are indicated.

From the tool's definition 'preview' and 'retention preview' indicate this tool builds/displays a preview without modifying data

RECOMMENDED RULE

The rule that runs preview_memory_retention_policy 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_memory_retention_policy, this is the rule to start with:

preview_memory_retention_policy Allowed

preview_memory_retention_policy is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "preview_memory_retention_policy": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mapi Agent Memory, apply this rule, and every preview_memory_retention_policy call is checked against it from then on.
