AI agents call jira_search_users to retrieve information from Sage MCP 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 Jira user data. It has no side effects, does not create, modify, or delete data, and does not execute code or trigger external operations. It falls squarely into the Read category. The severity is low because user directory searches are typically low-risk operations with limited blast radius even if misused by an agent.
From the tool's definition Tool name 'jira_search_users' and description 'Search for Jira users' indicate a query operation that retrieves user information without modifying data.
Documented attack patterns abuse exactly the kind of access jira_search_users gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for jira_search_users:
{
"version": "1",
"default": "deny",
"tools": {
"jira_search_users": {}
}
}jira_search_users is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for Jira users. It is categorised as a Read tool in the Sage MCP MCP Server, which means it retrieves data without modifying state.
Register the Sage MCP server in PolicyLayer and add a rule for jira_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 Sage MCP. Nothing to install.
jira_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 jira_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 jira_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.
jira_search_users is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
