WHAT IT DOES

What memory_put does on AirMCP

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

RISK

Why memory_put is rated Medium

This tool creates new or modifies existing memory/context entries. It is reversible (entries can be updated again or removed by other tools), so it does not qualify as Destructive. It does not execute code, trigger external operations, move money, or merely read data. Write is the appropriate category.

From the tool's definition Tool name is 'memory_put' and description states 'Insert or update a context-memory entry', which are direct write operations that create or modify data.

RECOMMENDED RULE

The rule that runs memory_put safely

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

memory_put Rate-limited

memory_put 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 AirMCP, apply this rule, and every memory_put call is checked against it from then on.
