AI agents use federal_register_search to create or modify resources in Law. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call federal_register_search repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Law.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Search the US Federal Register for rules, proposed rules, and notices. Covers all federal agencies (SEC, CFTC, FDIC, OCC, Fed, FinCEN).. It is categorised as a Write tool in the Law MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Law MCP server in PolicyLayer and add a rule for federal_register_search: 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. Nothing to install.
federal_register_search is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the federal_register_search 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 federal_register_search. 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.
federal_register_search is provided by the Law MCP server (https://tooloracle.io/law/mcp/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
