What intentSendTransaction does on Agentek Eth
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.
Why intentSendTransaction is rated Critical
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.
Attacks that exploit this kind of access
The rule that runs intentSendTransaction safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Agentek Eth, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For intentSendTransaction, this is the rule to start with:
Any call to intentSendTransaction is blocked until a human approves it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Agentek Eth, apply this rule, and every intentSendTransaction call is checked against it from then on.
Questions about intentSendTransaction
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.
