AI agents call get_async_operation 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 retrieves status information about an existing operation. It has no side effects, does not create, modify, delete, or execute anything. Polling status is a read operation with minimal security risk.
From the tool's definition Tool description states 'Poll the status of an asynchronous operation by its operation ID' — this is a query/retrieval operation that checks status without modifying or executing anything.
Attacks that exploit this kind of access
Poll the status of an asynchronous operation by its operation ID. 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_async_operation: 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_async_operation 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_async_operation 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_async_operation. 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_async_operation 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.
