wait · UNO Game MCP Server MCP: Risk & Policy

WHAT IT DOES

What wait does on UNO Game MCP Server

AI agents invoke wait to trigger actions in UNO Game MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why wait needs a policy

This tool executes a blocking operation that suspends execution flow until a condition (turn availability) is met via Redis Pub/Sub messaging. While it does not directly modify data or delete information, it triggers external operations and controls program flow based on game state synchronization.

From the tool's definition Tool 'wait' blocks execution and uses Redis Pub/Sub for event-driven notifications, triggering behavior contingent on external game state changes.

Verdict

wait Rate-limited

wait stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about wait

What does the wait tool do? +

Block and wait until it is your turn. Uses Redis Pub/Sub for instant notification. It is categorised as a Execute tool in the UNO Game MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on wait? +

Register the UNO Game MCP Server MCP server in PolicyLayer and add a rule for wait: 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.

What risk level is wait? +

wait is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit wait? +

Yes. Add a rate_limit block to the wait 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.

How do I block wait completely? +

Set action: deny in the PolicyLayer policy for wait. 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.

What MCP server provides wait? +

wait 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.
