RISK

Why neuron_send_sticker is rated Medium

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs neuron_send_sticker safely

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

neuron_send_sticker Rate-limited

neuron_send_sticker 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.
