Get the Zero Network API reference — all 8 gRPC endpoints: Send, GetTransfer, GetHistory, GetBalance, GetAccount, BridgeIn, BridgeOut, GetBridgeStatus.
AI agents call zero_api_reference 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.
The tool fetches API reference documentation describing endpoints. It does not execute any of those endpoints or modify any data. This is a read/query operation with minimal blast radius.
From the tool's definition 'Get the Zero Network API reference' — retrieves documentation about gRPC endpoints; no side effects, purely informational
Attacks that exploit this kind of access
Get the Zero Network API reference — all 8 gRPC endpoints: Send, GetTransfer, GetHistory, GetBalance, GetAccount, BridgeIn, BridgeOut, GetBridgeStatus. 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_api_reference: 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_api_reference 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_api_reference 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_api_reference. 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_api_reference 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.
