MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Flow MCP tools

Financial · Critical transfer_erc20_token This tool commits financial obligations by transferring cryptocurrency tokens. Financial · Critical punchswap_swap This tool creates token swap transactions on a DEX (decentralized exchange), which constitutes a financial operation involving the exchange of cryptocurrency tokens. Execute · High execute_query This tool allows execution of arbitrary Cadence scripts, which are programs that can interact with blockchain state, query data, and potentially invoke transactions.

3 of Flow MCP's 18 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Flow MCP

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

Block financial tools by default

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

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

Cap read operations

{
  "get_account_info": {
    "limits": [
      {
        "counter": "get_account_info_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

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 Flow MCP

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

Yes. The Flow MCP server exposes 2 financial tools including punchswap_swap, transfer_erc20_token. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow.

How do I enforce a policy on Flow MCP? +

Register the Flow 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.
