Overview

AI-generated overview

A remote MCP endpoint that returns payment-backed trust scores for AI agents on Base, charged per check.

What it does
Aval exposes a remote MCP endpoint that provides trust scores for AI agents registered on Base under the ERC-8004 standard. According to the registry description, each check is payment-backed and costs $0.01 through x402. No individual tools are listed in the manifest, so the exact tool names and response format are not documented here.
When to use it
Consider it when an assistant needs to look up or verify the trustworthiness of an AI agent on Base before interacting with it, for example when screening counterparties in an agent-to-agent workflow. It is less relevant if you do not work with agents on Base or do not need per-check trust data.
Requirements
A remote streamable HTTP connection to the provider's endpoint; no local package or runtime is needed. The manifest declares no authentication, environment variables, or headers, but the description states each check costs $0.01 via x402, so a payment-capable client or wallet is likely required.
Before you install
The service is described as charging $0.01 per check through x402, so calls may spend real funds and a payment-capable client or wallet may need to be configured. The manifest declares no authentication, so requests to the endpoint are not tied to a verified identity. The provider is a third party, and queries are sent to its remote server; no tool list or privacy terms are available to review.
