Check whether a German statute or provision appears current (in force) in the ingested corpus. It is categorised as a Read tool in the German Law MCP Server MCP Server, which means it retrieves data without modifying state.
Register the German Law MCP Server MCP server in PolicyLayer and add a rule for check_currency: 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 German Law MCP Server. Nothing to install.
check_currency 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 check_currency 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 check_currency. 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.
check_currency is provided by the German Law MCP Server MCP server (nenna-ai-gmbh/german-law-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
