AI agents call check_domain_availability to retrieve information from Spaceship without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only lookup of domain availability status and pricing information. It does not create, modify, delete, or execute any actions; it only retrieves and returns data. There is no blast radius from misuse beyond potentially querying many domains, which has minimal security impact.
From the tool's definition Tool description states 'Check if one or more domains are available for registration and show pricing' — this is a query operation that retrieves availability and pricing information with no side effects or modifications.
Attacks that exploit this kind of access
Check if one or more domains are available for registration and show pricing. Provide up to 20 domains to check at once. It is categorised as a Read tool in the Spaceship MCP Server, which means it retrieves data without modifying state.
Register the Spaceship MCP server in PolicyLayer and add a rule for check_domain_availability: 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 Spaceship. Nothing to install.
check_domain_availability 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 check_domain_availability 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 check_domain_availability. 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.
check_domain_availability is provided by the Spaceship MCP server (naveenkm007/spaceship-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
