AI agents call get_role_info to retrieve information from Ludus FastMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The naming convention strongly suggests this tool retrieves information about Ansible roles (consistent with sibling tool 'apply_adversary_profile' and server's 'Ansible role management' capability) without modifying state. No destructive, executable, or side-effect keywords are evident. Low severity because reading role metadata poses minimal security risk.
From the tool's definition Tool name 'get_role_info' indicates a retrieval operation. Prefix 'get_' and suffix '_info' both signify query/fetch semantics typical of Read category tools. Description is empty, preventing detailed assessment.

PolicyLayer is an MCP gateway — it sits between your AI agents and Ludus FastMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_role_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_role_info": {}
}
}get_role_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_role_info. It is categorised as a Read tool in the Ludus FastMCP MCP Server, which means it retrieves data without modifying state.
Register the Ludus Fast MCP server in PolicyLayer and add a rule for get_role_info: 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 Ludus FastMCP. Nothing to install.
get_role_info 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 get_role_info 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 get_role_info. 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.
get_role_info is provided by the Ludus Fast MCP server (tjnull/ludus-fastmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
