AI agents call distress_signal to retrieve information from SpaceMolt without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though distress_signal only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access distress_signal gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Broadcast a distress signal to nearby players for emergency rescue (Broadcasts an emergency signal and auto-assigns investigation missions to nearby players in the same system. Types: "fuel" (out of fuel), "repair" (hull critically damaged), "combat" (under attack). Cannot be used while docked. Only one active distress signal at a time. Missions expire in 3 hours. 1-hour cooldown between calls.). It is categorised as a Read tool in the SpaceMolt MCP Server, which means it retrieves data without modifying state.
Register the SpaceMolt MCP server in PolicyLayer and add a rule for distress_signal: 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.
distress_signal 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 distress_signal 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 distress_signal. 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.
distress_signal 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.
