| Parameter | Type | Required | Description |
|---|---|---|---|
base_id | string | — | Station to browse listings at, given by either its Base ID or station POI ID (defaults to current station) |
class_id | string | — | Filter by ship class ID |
max_price | integer | — | Maximum price filter |
session_id | string | Yes | Your session ID from login/register |
Parameters from the server's own tool schema.
Why browse_ships is rated Low
Even though browse_ships only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs browse_ships safely
PolicyLayer is an MCP gateway: it sits between your AI agents and SpaceMolt, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For browse_ships, this is the rule to start with:
browse_ships 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 SpaceMolt, apply this rule, and every browse_ships call is checked against it from then on.
