send-vote · Defcon MCP: Risk & Policy

WHAT IT DOES

What send-vote does on Defcon

AI agents invoke send-vote to trigger actions in Defcon. 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 send-vote needs a policy

This tool triggers an external operation within the DEFCON game by casting a vote on a game event. It causes a state change in the game (the vote is registered and may influence game outcomes), making it an Execute-category action. It is not purely reading data, nor does it irreversibly destroy data or involve finances.

Verdict

send-vote Rate-limited

send-vote 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 send-vote

What does the send-vote tool do? +

Sends a vote for a game event. It is categorised as a Execute tool in the Defcon MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on send-vote? +

Register the Defcon MCP server in PolicyLayer and add a rule for send-vote: 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 Defcon. Nothing to install.

What risk level is send-vote? +

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

Can I rate-limit send-vote? +

Yes. Add a rate_limit block to the send-vote 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 send-vote completely? +

Set action: deny in the PolicyLayer policy for send-vote. 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 send-vote? +

send-vote is provided by the Defcon MCP server (jorisvddonk/defcon-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
