start_bot · MCP: Risk & Policy

WHAT IT DOES

What start_bot does on Mcp

AI agents invoke start_bot to trigger actions in Mcp. 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 start_bot needs a policy

This tool executes a process to start a Discord bot, which triggers external operations whose effects depend on the bot's configuration and permissions. While not inherently destructive or financial, starting a bot can have broad side effects (network activity, message sending, data access through the bot's Discord permissions).

From the tool's definition Tool name 'start_bot' and description 'Start des Discord Bottes' (Start Discord Bot) indicate launching an external service/application.

Verdict

start_bot Rate-limited

start_bot 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.
