README

@tensorfeed/x402-base-mcp

The x402 ecosystem's read MCP for Base. Verify on-chain USDC settlements, parse publisher manifests, and audit x402 payment receipts from any MCP-compatible AI agent.

npm install -g @tensorfeed/x402-base-mcp

Read-only. No private keys. Base mainnet first.

Why this exists

x402 is a payment protocol where agents pay merchants in USDC on Base for paid API responses. When an agent receives a payment receipt back, it has two options for verifying that the settlement actually happened the way the receipt claims:

Trust the merchant
Read the on-chain Transfer event itself

Most existing EVM MCP servers either require a private key (so the agent can also send transactions, which is operationally risky and unnecessary for verification), or are generic multi-chain readers that don't speak x402. This server is the read-only, x402-aware option. Drop it into a Claude Desktop or Claude Code session and any agent can verify x402 payments without operating a wallet.

The TensorFeed-flavor tools (verify_afta_federation, tf_payment_lookup) compose the same primitives against TF's canonical surfaces and demonstrate the pattern. Use them or ignore them; the generic tools work fine on their own.

Installation

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "tensorfeed-x402-base": {
      "command": "npx",
      "args": ["-y", "@tensorfeed/x402-base-mcp"]
    }
  }
}

Claude Code

claude mcp add tensorfeed-x402-base -- npx -y @tensorfeed/x402-base-mcp

Optional: bring your own RPC

The server defaults to the public Base RPC (https://mainnet.base.org), which is fine for casual use. For heavier workloads, set an Alchemy or Infura URL via TENSORFEED_RPC_URL. The URL must match the allowlist in src/rpc/allowlist.ts; anything else falls back to the public endpoint and logs a warning to stderr.

export TENSORFEED_RPC_URL="https://base-mainnet.g.alchemy.com/v2/YOUR_KEY"

Tools

Generic Base reads

Tool	Description
`balance`	Native ETH balance for an address
`usdc_balance`	USDC (Circle native bridged) balance for an address
`block_number`	Latest Base block number
`get_tx_receipt`	Full tx receipt with status, gas, and logs summary
`call`	Read-only contract call (eth_call, never broadcasts)
`recent_transfers`	USDC Transfer events involving an address over N blocks

x402-native verification

Tool	Description
`verify_x402_settlement`	Given a tx hash, expected recipient, and expected USDC amount, returns a structured verdict on whether the on-chain Transfer event matches.
`parse_x402_manifest`	Fetches `https://{domain}/.well-known/x402.json`, returns the structured manifest.
`usdc_recent_payments_to`	USDC transfers TO an address over N blocks; the merchant-side view.
`probe_x402_endpoint`	Probes any https URL and reports whether it returns a canonical x402-paid 402 response with `accepts[]`.
`decode_x402_payment_payload`	Offline decode of a base64 `X-PAYMENT` header (Coinbase x402 V2): returns scheme, network, version, EIP-3009 authorization, signature.

TensorFeed flavor

Tool	Description
`verify_afta_federation`	Calls TensorFeed's AFTA certification endpoint for a domain, returns a scored checklist.
`tf_payment_lookup`	Checks whether a tx hash is a USDC payment to TensorFeed's canonical wallet on Base.
`x402_publisher_health`	Returns current outcome + 24h/7d uptime + recent series for a domain monitored by TensorFeed's hourly x402 status probe.
`afta_federation_members`	Returns the canonical curated list of confirmed AFTA federation members (TF origin + federated members).
