AI agents call search_classes to retrieve information from Qtz Iris without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
This tool searches and retrieves metadata about classes in the InterSystems IRIS database. It is a read-only operation with no side effects—it merely queries and returns class information. The sibling tools like 'execute_sql', 'get_document', and 'list_documents' confirm this is a data retrieval context. No data is created, modified, deleted, or executed; therefore it is classified as Read with low severity.
From the tool's definition Tool name 'search_classes' and description '搜索 IRIS 数据库中的类' (search IRIS database classes) indicates a query/search operation that retrieves information about class definitions without modifying data.

搜索 IRIS 数据库中的类. It is categorised as a Read tool in the Qtz Iris MCP Server, which means it retrieves data without modifying state.
search_classes accepts 1 parameter: searchTerm. The full parameter table on this page comes from the server's own tool schema.
Register the Qtz Iris MCP server in PolicyLayer and add a rule for search_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 Qtz Iris. Nothing to install.
search_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 search_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 search_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.
search_classes is provided by the Qtz Iris MCP server (qtz-iris-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
