WHAT IT DOES

What set_home_base does on SpaceMolt

AI agents use set_home_base 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
`base_id`	string	Yes	UUID of base to set as home (must be docked there)
`session_id`	string	Yes	Your session ID from login/register

Parameters from the server's own tool schema.

RISK

Why set_home_base is rated Medium

This tool modifies game state by changing the player's designated respawn location. While the change is reversible (the player can call the function again from another base), it has meaningful consequences for gameplay (affecting where the agent respawns after destruction).

From the tool's definition Tool description states it "Sets your current docked base as your home base," which is a state modification operation that persists user configuration.

RECOMMENDED RULE

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

set_home_base Rate-limited

set_home_base 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.
