vet402 · MCP server
vet402-check reads the public record of purchases that vet402 makes from x402 and MPP sellers with its own money on Solana, Tempo and Base, and returns the facts for one seller. They include purchases tried and settled, failures counted against the seller, the published grade and the signed records. Three read-only MCP tools check a seller before paying, verify a signed record and diagnose a failed payment as seller side, facilitator side or buyer side. A command line and an x402 fetch hook are included.

Why it's useful
Your agent can look at what vet402 found when it bought from a seller before spending, and the decision stays with you.
What you could do with it
- Check an x402 seller URL before your agent pays it and see how many of vet402's purchases settled.
- Compare the amount and pay-to address in a 402 offer with what vet402 recorded paying that seller.
- Verify a signed record, or diagnose a failed payment as seller side, facilitator side or buyer side.
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
Look an x402 or MPP seller up in vet402's public record before an agent pays it: a CLI, an MCP server and an x402 fetch hook. Read-only.

How far this has been checked
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 0.2.0, the file with digest sha512-fB5+gNs4WhSY36CPK5YgwXTDB5Jwl9xtsyKWwPloF8qfjnGmHqrWW3xE73awKpMQaaRATQ/zMySPLfdsbjk3tA==, 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.
The badge, if this is your listing
It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
