X402 Base MCP
tensorfeed · MCP server
X402 Base MCP is a read-only server for checking x402 payments, the protocol where agents pay merchants in USDC on Base for API responses. Given a transaction hash, an expected recipient and an amount, it returns a structured verdict on whether the on-chain transfer matches. It can also read balances, receipts and recent transfers, parse a publisher's x402 manifest, probe a URL for an x402 payment response and decode a payment header. Extra tools query TensorFeed's AFTA federation status.

Why it's useful
Your agent can confirm an x402 payment really settled on-chain instead of taking the merchant's word for the receipt.
What you could do with it
- Verify an x402 settlement from a transaction hash, the expected recipient and the expected USDC amount.
- Ask your assistant to fetch and parse the x402 manifest published by a domain.
- Probe an endpoint to see whether it returns a proper x402 payment response.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Read-only MCP server for verifying x402 USDC settlements on Base mainnet. The verify-side companion to Coinbase Base MCP, with AFTA federation helpers.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.2.1, the file with digest sha512-HJ9AQSt5ubl5GFdKal47UMHXnKfd5zu3BuSL9OFJZXwchJlmZFDh9vstuwr2u7yK35fYGVsbPnqTLctxs6wLqQ==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
