AI agents call find_revisions to retrieve information from Law Diff without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool scans and queries an e-Gov database to retrieve revision IDs matching specified criteria (date range, law ID, or keyword). It is a read-only retrieval operation with no side effects. The low severity reflects minimal risk if misused by an AI agent, as it only exposes publicly available legal revision information without capability to modify, execute, or delete data.
From the tool's definition Tool description states it 'Scan[s] e-Gov updated-law lists' and 'find[s] revision IDs' — purely a search/lookup operation that retrieves metadata about law revisions. No modification, deletion, execution, or financial operations are involved.
Attacks that exploit this kind of access
Scan e-Gov updated-law lists across a date range and find revision IDs for one law ID or keyword. Use this before diff_revisions when you need candidate law history IDs. It is categorised as a Read tool in the Law Diff MCP Server, which means it retrieves data without modifying state.
Register the Law Diff MCP server in PolicyLayer and add a rule for find_revisions: 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 Law Diff. Nothing to install.
find_revisions 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 find_revisions 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 find_revisions. 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.
find_revisions is provided by the Law Diff MCP server (shayouworld/law-diff-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
