AI agents call package_granulates to retrieve information from Gov info api without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries the structure of government documents (granules/sections) without creating, modifying, deleting, or executing any operations. It is a pure information retrieval function against government API data, making it a straightforward Read category tool with low severity risk.
From the tool's definition Tool description explicitly states it LISTs document sections and is used for 'navigating' regulatory documents with 'pagination support'.

🔍 LIST DOCUMENT SECTIONS (granules) within large documents. Bills typically have no granules (single document), but CFR and large publications are split into sections. Tested: CFR-2025-title8-vol1 has 1,298 granules including Table of Contents, Department chapters, and individual regulation sections. Use for navigating complex regulatory documents with pagination support. It is categorised as a Read tool in the Gov info api MCP Server, which means it retrieves data without modifying state.
Register the Gov info api MCP server in PolicyLayer and add a rule for package_granulates: 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 Gov info api. Nothing to install.
package_granulates 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 package_granulates 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 package_granulates. 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.
package_granulates is provided by the Gov info api MCP server (n00dlefr34k/gov-info-api-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
