get_validator_status
AI agents call get_validator_status 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 retrieves validator status information without modifying state, executing code, or performing financial operations. It is a read-only query operation consistent with monitoring and tracking use cases. Confidence is slightly reduced (0.85 rather than higher) due to the empty description, but context from server purpose and sibling tools strongly supports Read classification.
From the tool's definition Tool name 'get_validator_status' combined with server purpose of 'tracks Ethereum's validator activation and exit queues in real time' and sibling tools 'get_activation_queue' and 'get_exit_queue' all indicate data retrieval operations.
Attacks that exploit this kind of access
get_validator_status. 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_validator_status: 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_validator_status 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_validator_status 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_validator_status. 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_validator_status 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.
