AI agents call get_classes to retrieve information from CDISC Library MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about CDISC standard classes—a read-only operation with no side effects. It does not create, modify, delete, or execute any operations.

Register the CDISC Library MCP Server MCP server in PolicyLayer and add a rule for get_classes: 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 CDISC Library MCP Server. Nothing to install.
get_classes 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 get_classes 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 get_classes. 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.
get_classes is provided by the CDISC Library MCP Server MCP server (whereayan/cdisc-library-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
