Draw a card from the draw pile. Your turn then passes to the opponent.
AI agents call draw to retrieve information from UNO Game MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though draw only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Draw a card from the draw pile. Your turn then passes to the opponent. It is categorised as a Read tool in the UNO Game MCP Server MCP Server, which means it retrieves data without modifying state.
Register the UNO Game MCP Server MCP server in PolicyLayer and add a rule for draw: 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 UNO Game MCP Server. Nothing to install.
draw 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 draw 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 draw. 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.
draw is provided by the UNO Game MCP Server MCP server (viswajit2304/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
draw is one line of UNO Game MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
