AI agents call get_l2_receipt to retrieve information from Z2 Zetrix without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
This tool queries and returns transaction receipt information (status, block number, logs) from an L2 system. It performs a read-only lookup operation with no side effects, no code execution, and no data modification. The return of null or receipt data confirms it is a retrieval function. Severity is low as misuse would only expose historical transaction metadata without enabling unauthorized operations.
From the tool's definition Tool name 'get_l2_receipt' and description 'L2 tx receipt: { status(1/0), blockNumber, logs } or null' indicate retrieval of transaction receipt data without modification or execution.

Register the Z2 Zetrix MCP server in PolicyLayer and add a rule for get_l2_receipt: 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 Z2 Zetrix. Nothing to install.
get_l2_receipt 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 get_l2_receipt 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 get_l2_receipt. 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.
get_l2_receipt is provided by the Z2 Zetrix MCP server (z2-zetrix-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_l2_receipt is one line of Z2 Zetrix's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
