Why tokens_send_ft needs a policy

The name 'tokens_send_ft' on a NEAR blockchain MCP server almost certainly transfers fungible tokens (FT) between accounts. Sending tokens is a financial operation that moves value on-chain and is irreversible once confirmed. Combined with sibling tools like account_delete_account and account_delete_access_keys suggesting high-privilege operations, misuse could result in permanent loss of funds.

From the tool's definition Tool name 'tokens_send_ft' strongly implies sending fungible tokens on the NEAR blockchain, which constitutes a financial transfer operation. Description is empty, lowering confidence slightly.

POLICY

How to control tokens_send_ft

PolicyLayer is an MCP gateway — it sits between your AI agents and NEAR MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for tokens_send_ft:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "tokens_send_ft": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to tokens_send_ft is blocked until a human approves it. The rest of the server keeps working.
