MOST DANGEROUS TOOLS

Critical Risk

Financial · Critical transfer This tool directly transfers blockchain assets (SOL) using a private key, committing financial value to another address. Financial · Critical executeSwap This tool performs actual token swaps on-chain using a stored private key, which constitutes a financial transaction moving cryptocurrency assets. Financial · Critical approveEvmToken Approving ERC-20 token spending grants a spender address permission to transfer tokens on the user's behalf, up to the approved amount. Financial · Critical createXrpTrustline Creating a trustline on XRP Ledger is a financial operation that establishes a commitment to hold and transact a specific token, effectively enabling financial exposure to that asset.

10 of Web3 MCP Server's 55 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

HOW TO CONTROL WEB3 MCP SERVER

PolicyLayer is an MCP gateway — it sits between your AI agents and Web3 MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Block financial tools by default

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

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

Cap read operations

{
  "getAccountInfo": {
    "limits": [
      {
        "counter": "getaccountinfo_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.
