Get the Zero transaction wire format (136 bytes), account state format (48 bytes), and cryptographic primitives.
AI agents call zero_transaction_format 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 returns structured data about transaction formats and cryptographic specifications. It is informational and read-only; it does not execute transactions, modify state, delete data, or move funds. The data returned appears to be reference documentation for developers implementing Zero Network integration.
From the tool's definition Tool provides retrieval of transaction format specifications, account state format, and cryptographic primitives documentation—'Get the Zero transaction wire format', 'account state format', and 'cryptographic primitives' are descriptive/reference operations…
Attacks that exploit this kind of access
Get the Zero transaction wire format (136 bytes), account state format (48 bytes), and cryptographic primitives. 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_transaction_format: 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_transaction_format 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_transaction_format 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_transaction_format. 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_transaction_format 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.
