WHAT IT DOES

What shutdown does on MCP Trader Server

AI agents invoke shutdown to trigger actions in MCP Trader 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.

RISK

Why shutdown is rated High

This tool terminates the connection to the MetaTrader 5 terminal, which is an external operation that disables all trading capabilities (real-time data, order execution, portfolio management).

RECOMMENDED RULE

The rule that runs shutdown safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MCP Trader Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For shutdown, this is the rule to start with:

shutdown Rate-limited

shutdown 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 shutdown

What does the shutdown tool do? +

Shut down the connection to the MetaTrader 5 terminal. It is categorised as a Execute tool in the MCP Trader 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 shutdown? +

Register the MCP Trader Server MCP server in PolicyLayer and add a rule for shutdown: 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 MCP Trader Server. Nothing to install.

What risk level is shutdown? +

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

Can I rate-limit shutdown? +

Yes. Add a rate_limit block to the shutdown 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 shutdown completely? +

Set action: deny in the PolicyLayer policy for shutdown. 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 shutdown? +

shutdown is provided by the MCP Trader Server MCP server (af7007/mcp-trader). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
