What media_key does on Mcp Hands
AI agents use media_key to create or update resources in Mcp Hands, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Hands environment.
Why media_key is rated Medium
An AI agent can call media_key faster than any human can review: one bad instruction and it creates or modifies resources in Mcp Hands by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs media_key safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Hands, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For media_key, this is the rule to start with:
media_key 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 Mcp Hands, apply this rule, and every media_key call is checked against it from then on.
