AI agents call get_auth_code 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.
This tool retrieves authentication credentials (EPP code) needed for domain transfers. While it is technically a read operation with no side effects on data integrity, it exposes sensitive authentication material that could be misused to initiate unauthorized domain transfers if obtained by an attacker.
From the tool's definition Tool name 'get_auth_code' and description 'Retrieve the authorization/EPP code for domain transfer' both indicate data retrieval with no modifications.
Attacks that exploit this kind of access
Retrieve the authorization/EPP code for domain transfer. 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 get_auth_code: 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.
get_auth_code 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 get_auth_code 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 get_auth_code. 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.
get_auth_code 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.
