AI agents call get_cdash_domain_fields 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 tool retrieves CDASH (Clinical Data Acquisition Standards Harmonization) domain field definitions from the CDISC Library API. It has no side effects, does not modify data, execute code, or trigger external operations. It is purely informational, returning standards reference data to support clinical research workflows.
From the tool's definition Tool name 'get_cdash_domain_fields' and description 'Get all data collection fields for a CDASH domain' indicate a retrieval operation. The verb 'Get' and the lack of any modification, deletion, or execution language confirm this is a read-only query.

Get all data collection fields for a CDASH domain. 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_domain_fields: 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_domain_fields 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_domain_fields 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_domain_fields. 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_domain_fields 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.
