Get validator documentation — hardware requirements, staking, trust scoring, slashing rules, economics.
AI agents call zero_validator_info to retrieve information from Zero Network 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 reference documentation about validators, staking mechanics, and economic parameters. It has no side effects, does not execute code, does not modify data, and does not process financial transactions. It is purely informational, fitting the Read category with low severity as misuse would only expose information without enabling harmful actions.
From the tool's definition Tool provides access to documentation and information retrieval about validator requirements and economics. No modification, execution, or financial transaction capabilities. Description uses only passive retrieval verbs: 'Get validator documentation.'
Attacks that exploit this kind of access
Get validator documentation — hardware requirements, staking, trust scoring, slashing rules, economics. It is categorised as a Read tool in the Zero Network MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Zero Network MCP Server MCP server in PolicyLayer and add a rule for zero_validator_info: 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 Zero Network MCP Server. Nothing to install.
zero_validator_info 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 zero_validator_info 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 zero_validator_info. 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.
zero_validator_info is provided by the Zero Network MCP Server MCP server (zzero-net/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
