Find users by search query
AI agents call find_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 searches and retrieves user information from Jira. It does not create, modify, delete, or execute any actions; it only queries and returns data. The blast radius of misuse is minimal—an AI agent could retrieve user lists but cannot cause damage. This is a clear Read operation.
From the tool's definition Tool name is 'find_users' and description states 'Find users by search query' — a retrieval operation with no side effects.
Attacks that exploit this kind of access
Find users by search query. 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 find_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.
find_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 find_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 find_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.
find_users is provided by the Jira MCP Server MCP server (sespinosa/jira-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
