AI agents call search_items to retrieve information from Mcp Jama without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
search_items performs a query-based search operation that retrieves data without creating, modifying, deleting, or executing code. It is a read-only operation similar to search or filter functions. The wildcard support (brake*) indicates parametrized searching rather than arbitrary code execution. No financial impact or destructive capability is present.
From the tool's definition Tool description states it searches items by keyword (アイテムをキーワード検索する) with query mapped to a contains parameter and wildcard support. This is a retrieval operation with no mutation or side effects.

Register the Mcp Jama MCP server in PolicyLayer and add a rule for search_items: 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 Mcp Jama. Nothing to install.
search_items 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_items 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_items. 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_items is provided by the Mcp Jama MCP server (keisukeshima/mcp-jama). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
