AI agents call get_eligible_actions to retrieve information from MCP4DRL without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on naming convention and context, this tool appears to retrieve or list valid actions available in a given state without modifying the environment or executing external operations. The empty description lowers confidence, but the category is most consistent with Read (query/retrieval) rather than Write, Execute, or Destructive. No financial implications.
From the tool's definition Tool name 'get_eligible_actions' suggests querying available actions from the RL model state. The description is empty, but sibling tools like 'get_environment_state', 'get_q_values', and 'explain_action' are all read-only query operations typical of RL model…
Attacks that exploit this kind of access
get_eligible_actions. It is categorised as a Read tool in the MCP4DRL MCP Server, which means it retrieves data without modifying state.
Register the MCP4DRL MCP server in PolicyLayer and add a rule for get_eligible_actions: 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 MCP4DRL. Nothing to install.
get_eligible_actions 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_eligible_actions 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_eligible_actions. 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_eligible_actions is provided by the MCP4DRL MCP server (mostapow/mcp4drl). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
