AI agents call get_cdash_domains to retrieve information from Cdisc without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves and lists CDASH (Clinical Data Acquisition Standards Harmonization) domain metadata. It performs no writes, deletions, code execution, or financial operations. The only action is querying and returning standardized reference data, making it a safe Read category tool with low severity.
From the tool's definition Tool name 'get_cdash_domains' and description 'List all CDASH domains for a given version' indicate data retrieval with no modification or side effects.
Attacks that exploit this kind of access
List all CDASH domains for a given version. It is categorised as a Read tool in the Cdisc MCP Server, which means it retrieves data without modifying state.
Register the Cdisc MCP server in PolicyLayer and add a rule for get_cdash_domains: 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. Nothing to install.
get_cdash_domains 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_cdash_domains 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_cdash_domains. 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_cdash_domains is provided by the Cdisc MCP server (teninq/cdisc-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
