`name`	string	—	The name of the planet.
`offset`	integer	—	Number of results to offset for pagination.
`max_mass`	number	—	Maximum mass of the planet in Jupiters.
`min_mass`	number	—	Minimum mass of the planet in Jupiters.
`max_period`	integer	—	Maximum orbital period of the planet in Earth days.
`max_radius`	number	—	Maximum average radius of the planet in Jupiters.
`min_period`	integer	—	Minimum orbital period of the planet in Earth days.
`min_radius`	number	—	Minimum average radius of the planet in Jupiters.
`max_temperature`	integer	—	Maximum average surface temperature of the planet in Kelvin.
`min_temperature`	integer	—	Minimum average surface temperature of the planet in Kelvin.

RECOMMENDED RULE

The rule that runs Get_a_list_of_planets safely

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

Get_a_list_of_planets Allowed

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