What nasaexoplanet.planets.search does on Apibase
AI agents call nasaexoplanet.planets.search 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 results to return (default 20, max 100) |
mass_max | number | — | Maximum planet mass in Earth masses (e.g. 318 ≈ 1 Jupiter mass) |
mass_min | number | — | Minimum planet mass in Earth masses (e.g. 0.1 for sub-Earths) |
host_name | string | — | Host star name or partial name (e.g. "51 Peg", "Kepler-442") |
radius_max | number | — | Maximum planet radius in Earth radii (e.g. 2.0 for super-Earths; 11 ≈ Jupiter) |
radius_min | number | — | Minimum planet radius in Earth radii (e.g. 0.5 for sub-Earths and above) |
planet_name | string | — | Planet name or partial name to search (e.g. "Kepler-22 b", "TOI-700") |
disc_year_max | integer | — | Maximum discovery year (e.g. 2020 to filter planets found before 2021) |
disc_year_min | integer | — | Minimum discovery year (e.g. 2010 to filter planets found in 2010 or later) |
discovery_method | string | — | Discovery method filter (e.g. "Transit", "Radial Velocity", "Imaging") |

Attacks that exploit this kind of access
The rule that runs nasaexoplanet.planets.search 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.search, this is the rule to start with:
nasaexoplanet.planets.search 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.search call is checked against it from then on.
Questions about nasaexoplanet.planets.search
Search NASA Exoplanet Archive for confirmed exoplanets by name, host star, discovery method, year range, radius, or mass. Returns orbital period, radius, mass, equilibrium temperature, discovery year and facility, and system distance. 6,298+ confirmed planets from Transit, Radial Velocity, Imaging, and Microlensing surveys (NASA Exoplanet Archive). It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
nasaexoplanet.planets.search accepts 10 parameters: limit, mass_max, mass_min, host_name, radius_max, radius_min, planet_name, disc_year_max, disc_year_min, discovery_method. 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.search: 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.search 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.search 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.search. 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.search 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.
