Why predictTransferId needs a policy

The tool predicts (computes/estimates) a transfer ID for a hypothetical transfer. This is a read-only operation with no side effects - it does not execute any transfer or modify any state. The result is informational only.

From the tool's definition 'Predict a transfer ID for a potential transfer' - this is a read/computation operation that predicts/calculates an ID without executing any transaction

POLICY

How to control predictTransferId

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 predictTransferId:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "predictTransferId": {}
  }
}

predictTransferId is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Agentek Eth — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about predictTransferId

What does the predictTransferId tool do? +

Predict a transfer ID for a potential transfer. It is categorised as a Read tool in the Agentek Eth MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on predictTransferId? +

Register the Agentek Eth MCP server in PolicyLayer and add a rule for predictTransferId: 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.

What risk level is predictTransferId? +

predictTransferId is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit predictTransferId? +

Yes. Add a rate_limit block to the predictTransferId 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.

How do I block predictTransferId completely? +

Set action: deny in the PolicyLayer policy for predictTransferId. 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.

What MCP server provides predictTransferId? +

predictTransferId 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.

Enforce policy on every Agentek Eth tool call.

Start from Agentek Eth, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
