List semantic layer domains with filtering options
AI agents call jasper_list_domains to retrieve information from Jasperreports without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and filters information about semantic layer domains in JasperReports Server. It performs a query operation without side effects, matching the Read category definition. The filtering is applied to query results, not to data modification.
From the tool's definition Tool name contains 'list' and description states 'List semantic layer domains with filtering options' - a pure data retrieval operation with no modification, deletion, or execution capability.
Documented attack patterns abuse exactly the kind of access jasper_list_domains gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Jasperreports, and nothing reaches the server without passing your rules. This is the rule we recommend for jasper_list_domains:
{
"version": "1",
"default": "deny",
"tools": {
"jasper_list_domains": {}
}
}jasper_list_domains is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List semantic layer domains with filtering options. It is categorised as a Read tool in the Jasperreports MCP Server, which means it retrieves data without modifying state.
Register the Jasperreports MCP server in PolicyLayer and add a rule for jasper_list_domains: 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 Jasperreports. Nothing to install.
jasper_list_domains 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 jasper_list_domains 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 jasper_list_domains. 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.
jasper_list_domains is provided by the Jasperreports MCP server (mr-wolf-gb/jasperreports-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Jasperreports, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
