Search for users by username, email, or display name
AI agents call search_users to retrieve information from Jira MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search/query operation to retrieve user data from Jira. It has no side effects, does not modify or delete data, and does not execute code or trigger financial transactions. It falls squarely into the Read category as a data retrieval function.
From the tool's definition Tool name 'search_users' and description 'Search for users by username, email, or display name' indicates a query operation that retrieves user information without modifying, deleting, or executing actions.
Attacks that exploit this kind of access
Search for users by username, email, or display name. It is categorised as a Read tool in the Jira MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Jira MCP Server MCP server in PolicyLayer and add a rule for search_users: 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 Jira MCP Server. Nothing to install.
search_users 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_users 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_users. 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_users is provided by the Jira MCP Server MCP server (orengrinker/jira-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
