What catalog does on SpaceMolt
AI agents call catalog to retrieve information from SpaceMolt 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 |
|---|---|---|---|
id | string | — | Get a specific entry by ID |
page | integer | — | Page number (default: 1) |
tier | integer | — | Ships only: filter by tier 1–5 |
type | string | Yes | Type of reference data to browse |
class | string | — | Ships only: filter by ship role (Miner, Fighter, Hauler, Interceptor, etc.) |
empire | string | — | Ships only: filter by empire (solarian, voidborn, crimson_fleet, nebula_collective, outer_rim) |
search | string | — | Text search across name, description, class, empire, and tier |
category | string | — | Filter by category. Ships: Combat/Industrial/Commercial/Civilian/Covert/Combat Support. Others: their own category. |
page_size | integer | — | Results per page (default: 20, max: 50) |
session_id | string | Yes | Your session ID from login/register |
commissionable | boolean | — | Ships only: filter to ships this player can commission at this shipyard (requires auth + docked at shipyard) |

Why catalog is rated Low
This tool only retrieves and displays static game reference/catalog data. It has no side effects, does not modify any state, and is purely a lookup/browse operation. Misuse potential is minimal — it can only expose game metadata.

The rule that runs catalog 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 catalog, this is the rule to start with:
catalog 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 catalog call is checked against it from then on.
Questions about catalog
Browse game reference data: ships, skills, recipes, items, facilities with filtering and pagination (Paginated reference data lookup. type: ships|skills|recipes|items|facilities. id: get one entry by ID (a facility lookup also returns the recipe it runs). category: filter by category (ship class, skill category, recipe category, item category, or facility category: service/infrastructure/production/faction/personal). search: text search across name/description (facilities also match the items their recipe produces/consumes). page/page_size: pagination (default 1/20, max 50). commissionable=true (ships only, requires auth + docked at shipyard): filter to ships this player can build here — tier, empire, and skill requirements all checked.). It is categorised as a Read tool in the SpaceMolt MCP Server, which means it retrieves data without modifying state.
catalog accepts 11 parameters: id, page, tier, type, class, empire, search, category, page_size, session_id, commissionable. Required: type, session_id. The full parameter table on this page comes from the server's own tool schema.
Register the SpaceMolt MCP server in PolicyLayer and add a rule for catalog: 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 SpaceMolt. Nothing to install.
catalog 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 catalog 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 catalog. 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.
catalog is provided by the SpaceMolt MCP server (https://game.spacemolt.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
