The rule that runs climate.indicators.methane safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For climate.indicators.methane, this is the rule to start with:
climate.indicators.methane 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 Apibase, apply this rule, and every climate.indicators.methane call is checked against it from then on.
