Get information about Nimiq validators. By default, it returns only active validators.
AI agents call get_nimiq_validators to retrieve information from Nimiq MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries validator information from the Nimiq blockchain without creating, modifying, deleting, or executing any operations. It has no capability to alter state or trigger external actions. The blast radius of misuse is minimal—an agent could only access public blockchain data that is already visible on-chain.
From the tool's definition Tool name 'get_nimiq_validators' and description 'Get information about Nimiq validators' indicate a retrieval operation with no side effects. The qualifier 'by default, it returns only active validators' confirms this is a read-only query operation.
