get_exit_queue
AI agents call get_exit_queue to retrieve information from Ethereum Validator Queue without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries staking queue data without creating, modifying, deleting, or executing operations. It enables passive monitoring of network state. Even though the description is empty, the tool name and server context make the classification clear: it is a read-only query operation with minimal risk.
From the tool's definition Tool name is 'get_exit_queue' which retrieves information about Ethereum's validator exit queue. The verb 'get' indicates a retrieval operation with no side effects.
Attacks that exploit this kind of access
get_exit_queue. It is categorised as a Read tool in the Ethereum Validator Queue MCP Server, which means it retrieves data without modifying state.
Register the Ethereum Validator Queue MCP server in PolicyLayer and add a rule for get_exit_queue: 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 Ethereum Validator Queue. Nothing to install.
get_exit_queue 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_exit_queue 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_exit_queue. 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_exit_queue is provided by the Ethereum Validator Queue MCP server (kukapay/ethereum-validator-queue-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
