Send an arbitrary transaction to any address. Specify a human-readable ABI signature with function name and arguments to encode calldata automatically, or provide raw hex data. Use this for any contract interaction not covered by other tools.
AI agents use intentSendTransaction to commit financial operations through Agentek Eth — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Sending blockchain transactions can transfer ETH/tokens (Financial), invoke destructive contract functions, or execute arbitrary on-chain logic. The tool is explicitly general-purpose ('arbitrary transaction to any address'), meaning an AI agent could use it to drain wallets, interact with malicious contracts, or commit irreversible financial actions.
From the tool's definition "Send an arbitrary transaction to any address" and "Use this for any contract interaction not covered by other tools" — executes on-chain transactions that move funds or invoke smart contracts irreversibly.
Documented attack patterns abuse exactly the kind of access intentSendTransaction gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Agentek Eth, and nothing reaches the server without passing your rules. This is the rule we recommend for intentSendTransaction:
{
"version": "1",
"default": "deny",
"tools": {
"intentSendTransaction": {
"deny_if": [
{
"conditions": [],
"on_deny": "Requires human approval."
}
]
}
}
}Any call to intentSendTransaction is blocked until a human approves it. The rest of the server keeps working.

Send an arbitrary transaction to any address. Specify a human-readable ABI signature with function name and arguments to encode calldata automatically, or provide raw hex data. Use this for any contract interaction not covered by other tools. It is categorised as a Financial tool in the Agentek Eth MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Register the Agentek Eth MCP server in PolicyLayer and add a rule for intentSendTransaction: 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 Agentek Eth. Nothing to install.
intentSendTransaction is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the intentSendTransaction 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.
Set action: deny in the PolicyLayer policy for intentSendTransaction. 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.
intentSendTransaction is provided by the Agentek Eth MCP server (nanidao/agentek). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Agentek Eth, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
