Fetches a suggested fee quote for a cross-chain asset bridge using the Across Protocol REST API.
AI agents call getAcrossFeeQuote to retrieve information from Agentek Eth without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves informational data (fee quote) from an external API without creating, modifying, deleting, or executing any transactions. It has no capability to move funds, execute code, or trigger state-changing operations. The blast radius of misuse is minimal—an agent could only retrieve quote information repeatedly. Classification as Read is appropriate for this data retrieval operation.
From the tool's definition Tool description states it 'Fetches a suggested fee quote' which is a retrieval operation with no side effects. The verb 'fetches' and the action of obtaining a 'quote' (informational data) indicates a read-only query against the Across Protocol REST API.
Documented attack patterns abuse exactly the kind of access getAcrossFeeQuote 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 getAcrossFeeQuote:
{
"version": "1",
"default": "deny",
"tools": {
"getAcrossFeeQuote": {}
}
}getAcrossFeeQuote is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Agentek Eth MCP server in PolicyLayer and add a rule for getAcrossFeeQuote: 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.
getAcrossFeeQuote is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the getAcrossFeeQuote 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 getAcrossFeeQuote. 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.
getAcrossFeeQuote 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.
