Get a comprehensive overview of the Zero Network — what it is, how it works, key facts, and links.
AI agents call zero_overview 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 presents documentation/reference material about Zero Network. It does not modify data, execute code, trigger transactions, or perform destructive operations. The word 'overview' combined with 'key facts and links' clearly indicates a query/fetch operation that returns existing information without state changes.
From the tool's definition Tool description states it provides an 'overview' with 'facts and links' — purely informational retrieval with no side effects.

Register the Zero Network MCP Server MCP server in PolicyLayer and add a rule for zero_overview: 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_overview 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_overview 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_overview. 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_overview 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.
