AI agents call map_ctd_section to retrieve information from Regsub without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and returns reference information about CTD (Common Technical Document) regulatory structure. It is a lookup/mapping function that provides guidance on document classification without modifying, executing, or destroying any data. It falls squarely into the Read category as a query-like operation that returns structured reference information to support regulatory submission processes.

Map a document type or data package to the correct CTD/eCTD module and section. Returns the full section hierarchy. It is categorised as a Read tool in the Regsub MCP Server, which means it retrieves data without modifying state.
Register the Regsub MCP server in PolicyLayer and add a rule for map_ctd_section: 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 Regsub. Nothing to install.
map_ctd_section 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 map_ctd_section 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 map_ctd_section. 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.
map_ctd_section is provided by the Regsub MCP server (pubspro/regsub-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
