Fetch the tamper-evident audit log for a contract. Each event is hash-chained (prevHash + hash = SHA-256). Agent actions carry actor.kind=\
AI agents call get_audit_log to retrieve information from QuickContract MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves audit log data without side effects. While the server enables sensitive operations like signing contracts and releasing escrow, this specific tool is a read-only operation that only retrieves existing audit records. The hash-chaining is a security property of the data structure, not something the tool executes. No data is created, modified, deleted, or financial transactions occur.
From the tool's definition Tool name is 'get_audit_log' and description states 'Fetch the tamper-evident audit log' — retrieves historical data with no modification or execution capabilities.
Attacks that exploit this kind of access
Fetch the tamper-evident audit log for a contract. Each event is hash-chained (prevHash + hash = SHA-256). Agent actions carry actor.kind=\. It is categorised as a Read tool in the QuickContract MCP MCP Server, which means it retrieves data without modifying state.
Register the QuickContract MCP server in PolicyLayer and add a rule for get_audit_log: 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 QuickContract MCP. Nothing to install.
get_audit_log 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_audit_log 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_audit_log. 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_audit_log is provided by the QuickContract MCP server (quickcontractio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
