Overview

AI-generated overview

A remote MCP server that lets an assistant look up whether AI crawlers can see a given site, with paid checks settled in USDC on Base.

What it does
It provides a registry lookup service reachable over streamable HTTP at a fixed remote endpoint. According to the description, the lookup is free and reports whether an AI crawler sees your site, while x402 pricing applies to checks paid in USDC on Base. No individual tools are listed in the supplied manifest, so the exact tool names and parameters are not documented here.
When to use it
Worth considering when you want an assistant to check AI-crawler visibility for a site as part of an audit or monitoring routine. It is a narrow, single-purpose lookup rather than a general web or SEO toolkit.
Requirements
A remote MCP client that supports streamable HTTP, plus network access to the provider endpoint. No authentication, environment variables, or headers are declared. Paid checks involve USDC on Base, so a wallet or payment arrangement would be needed for those.
Before you install
The description states that some checks are paid in USDC on Base, so using them can spend real funds; confirm pricing and limits before enabling paid calls. The service is remote, so any site identifiers or query details you submit go to a third party. No credentials are declared, but treat any payment or wallet setup as sensitive.
