Get all available test case fields
AI agents call get_case_fields to retrieve information from TestRail 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 configuration or schema information (available field definitions) from TestRail. It performs a simple query with no side effects, no data modification, and no execution of external operations. It falls squarely within the Read category as a data retrieval operation.
From the tool's definition Tool name 'get_case_fields' with description 'Get all available test case fields' indicates a retrieval operation that queries metadata about test case fields without modifying any data.

Register the TestRail MCP Server MCP server in PolicyLayer and add a rule for get_case_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 TestRail MCP Server. Nothing to install.
get_case_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_case_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_case_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.
