Retrieve input control definitions for a report
AI agents call jasper_get_input_controls 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 metadata about input control definitions for a report. Retrieval operations that query data without modifying, deleting, or executing operations fall under the Read category. The severity is low because retrieving report metadata poses minimal security risk unless the metadata itself contains highly sensitive information, which is unlikely for input control definitions.
From the tool's definition Tool name 'jasper_get_input_controls' and description 'Retrieve input control definitions for a report' indicate a query/retrieval operation with no side effects.

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_get_input_controls:
{
"version": "1",
"default": "deny",
"tools": {
"jasper_get_input_controls": {}
}
}jasper_get_input_controls is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve input control definitions for a report. 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_get_input_controls: 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_get_input_controls 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_get_input_controls 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_get_input_controls. 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_get_input_controls 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.
