What nasaexoplanet.planets.habitable does on Apibase
AI agents call nasaexoplanet.planets.habitable to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
limit | integer | — | Maximum number of candidates to return (default 20, max 100) |
temp_max | number | — | Maximum equilibrium temperature in Kelvin (default 310 — conservative habitable zone upper bound) |
temp_min | number | — | Minimum equilibrium temperature in Kelvin (default 180 — conservative habitable zone lower bound) |
radius_max | number | — | Maximum planet radius in Earth radii (default 2.0 — upper limit for rocky planets) |
radius_min | number | — | Minimum planet radius in Earth radii (default 0.5 — filters sub-Earth bodies) |

Why nasaexoplanet.planets.habitable is rated Low
Tool retrieves NASA exoplanet data with no side effects, modifications, or external operations.
From the tool's definition Find potentially habitable exoplanets, returns radius, mass, orbital period, temperature.
Attacks that exploit this kind of access
The rule that runs nasaexoplanet.planets.habitable 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 nasaexoplanet.planets.habitable, this is the rule to start with:
nasaexoplanet.planets.habitable 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 nasaexoplanet.planets.habitable call is checked against it from then on.
Questions about nasaexoplanet.planets.habitable
Find potentially habitable exoplanets in the conservative habitable zone — planets with Earth-like radius (0.5–2.0 R⊕) and equilibrium temperature suitable for liquid water (180–310 K). Sorted by radius ascending. Returns radius, mass, orbital period, equilibrium temperature, insolation flux, and host star details. Customisable temperature and radius bounds for optimistic or strict filtering (NASA Exoplanet Archive — pscomppars table). It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
nasaexoplanet.planets.habitable accepts 5 parameters: limit, temp_max, temp_min, radius_max, radius_min. The full parameter table on this page comes from the server's own tool schema.
Register the Apibase MCP server in PolicyLayer and add a rule for nasaexoplanet.planets.habitable: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Apibase. Nothing to install.
nasaexoplanet.planets.habitable is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the nasaexoplanet.planets.habitable rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for nasaexoplanet.planets.habitable. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
nasaexoplanet.planets.habitable is provided by the Apibase MCP server (apibase-mcp-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
