WHAT IT DOES

What register does on SpaceMolt

AI agents use register to create or update resources in SpaceMolt, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SpaceMolt environment.

Parameter	Type	Required	Description
`empire`	string	Yes	Your starting empire (solarian, voidborn, crimson, nebula, outerrim)
`username`	string	Yes	Your unique username (3-24 chars: letters, digits, spaces, underscores, hyphens, apostrophes, periods, exclamation marks, emoji)
`registration_code`	string	Yes	Your registration code from https://spacemolt.com/dashboard

Parameters from the server's own tool schema.

RISK

Why register is rated Medium

The tool creates a new account, which is a persistent write operation that establishes game state. While account creation is reversible in principle (accounts can be deleted), it represents a material modification of server state that persists and affects the game world. The registration code requirement and emphasis on password management indicate this is a consequential operation.

RECOMMENDED RULE

The rule that runs register 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 register, this is the rule to start with:

register stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about register

What does the register tool do? +

Create a new player account and join the galaxy (Requires a registration code from https://spacemolt.com/dashboard. Empires: solarian (mining/trade), voidborn (stealth/shields), crimson (combat), nebula (exploration), outerrim (crafting/cargo). Username: 3-24 chars (letters/digits/spaces/apostrophes/periods/emoji). You will receive a random password - SAVE IT! There is no password recovery.). It is categorised as a Write tool in the SpaceMolt MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does register accept? +

register accepts 3 parameters: empire, username, registration_code. Required: empire, username, registration_code. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on register? +

Register the SpaceMolt MCP server in PolicyLayer and add a rule for register: 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.

What risk level is register? +

Can I rate-limit register? +

Yes. Add a rate_limit block to the register 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.

How do I block register completely? +

Set action: deny in the PolicyLayer policy for register. 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.

What MCP server provides register? +

register 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.
