概要

What is Tensorfeed X402 Base Mcp?

A read-only MCP server for verifying x402 USDC settlements on Base mainnet. It lets any MCP-compatible agent independently audit x402 payment receipts on-chain, parse publisher .well-known/x402 manifests, and check AFTA federation status without private keys, signing, or broadcasts.

How to use Tensorfeed X402 Base Mcp?

Install globally via npm, then add the server to claude_desktop_config.json or use claude mcp add. Configure an optional private RPC URL via the TENSORFEED_RPC_URL environment variable for heavier workloads.

FAQ from Tensorfeed X402 Base Mcp

How does this differ from Coinbase Base MCP?

Coinbase Base MCP is the transact-side server for proposing swaps, transfers, and x402 payments. This server is the verify-side — it independently confirms on-chain settlement after a payment has been made. They are complementary, not competing.

Does the server require a private key or wallet?

No. The server is read-only; it cannot move funds, sign, or broadcast transactions. It only checks on-chain data.

What RPC endpoint does it use, and can I bring my own?

It defaults to the public Base RPC (https://mainnet.base.org). For heavier workloads, set TENSORFEED_RPC_URL to an Alchemy or Infura URL that matches the allowlist in src/rpc/allowlist.ts.
