Why chat is rated Medium
This tool creates new data (chat messages) but does not modify, delete, execute code, trigger external operations, or move financial assets. It is reversible in effect (messages can be deleted by moderators or through normal game mechanics). The blast radius of misuse is minimal—spamming chat or sending unwanted messages causes social friction but no game-state corruption or financial harm.
From the tool's definition Tool 'sends a chat message' to various channels (system, local, faction, private). The description explicitly states it performs a send action, which creates new data (chat messages) in the game world.

The rule that runs chat 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 chat, this is the rule to start with:
chat 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.
The button opens the PolicyLayer dashboard: create your workspace, connect SpaceMolt, apply this rule, and every chat call is checked against it from then on.

Register the SpaceMolt MCP server in PolicyLayer and add a rule for chat: 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.
chat is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the chat 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 chat. 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.
chat 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.
