MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Composer Trade tools

Financial · High cancel_invest_or_withdraw This tool directly manipulates financial transactions by canceling pending invest/withdraw requests. Financial · Critical withdraw_from_symphony This tool moves money from an investment symphony (portfolio), which is a direct financial transaction that commits financial obligations and reallocates capital. Financial · High cancel_single_trade Cancelling a trade is a financial operation that directly affects investment activity. Financial · Critical execute_single_trade The tool name 'execute_single_trade' strongly implies it places a financial trade, which is a Financial category action.

13 of Composer Trade's 24 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Composer Trade

PolicyLayer is an MCP gateway — it sits between your AI agents and Composer Trade, and nothing reaches the server without passing your rules. These are the rules we recommend:

Block financial tools by default

{
  "cancel_invest_or_withdraw": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Requires human approval."
      }
    ]
  }
}

Financial tools should be explicitly enabled per use case, not open by default.

Rate limit write operations

{
  "save_symphony": {
    "limits": [
      {
        "counter": "save_symphony_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_account_holdings": {
    "limits": [
      {
        "counter": "get_account_holdings_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Composer Trade — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Composer Trade

Can an AI agent move money through the Composer Trade MCP server? +

Yes. The Composer Trade server exposes 8 financial tools including cancel_invest_or_withdraw, cancel_single_trade, create_symphony. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.

How do I prevent bulk modifications through Composer Trade? +

The Composer Trade server has 2 write tools including save_symphony, update_saved_symphony. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Composer Trade.

How many tools does the Composer Trade MCP server expose? +

24 tools across 5 categories: Destructive, Execute, Financial, Read, Write. 11 are read-only. 13 can modify, create, or delete data.

How do I enforce a policy on Composer Trade? +

Register the Composer Trade MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
