AI agents use federal_register to create or modify resources in Dynamic Feed. 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 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 Dynamic Feed.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Recent US Federal Register documents — rules, proposed rules, notices, executive orders (keyless). doc_type = RULE | PRORULE | NOTICE | PRESDOCU. Answers 'what regulation took effect / what did the President sign' — total post-cutoff blindness for models.. It is categorised as a Write tool in the Dynamic Feed MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Dynamic Feed MCP server in PolicyLayer and add a rule for federal_register: 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 Dynamic Feed. Nothing to install.
federal_register 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 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. 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 is provided by the Dynamic Feed MCP server (https://dynamicfeed.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
