AI agents call jira_list_versions 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 query operation that retrieves project version information with no side effects, data modification, or external state changes. It falls squarely into the Read category with low severity since version listing is informational only and poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'jira_list_versions' and description 'List versions/releases for a project' indicate a read-only operation that retrieves and lists existing version/release data without modification.
Documented attack patterns abuse exactly the kind of access jira_list_versions 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_list_versions:
{
"version": "1",
"default": "deny",
"tools": {
"jira_list_versions": {}
}
}jira_list_versions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List versions/releases for a project. 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_list_versions: 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_list_versions 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_list_versions 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_list_versions. 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_list_versions 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.
