## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.

## MCP tools (3)

### `check_x402_endpoint` (~113 tokens)

Check a paid x402 endpoint before paying it. First 10 checks free, then about $0.01 in USDC on Base.

Returns payer depth first: how many distinct wallets paid the endpoint's receiving address
(x402-style, last 30 days), repeat-payer share, payer concentration and coverage, with a
one-line statement. Then the full on-chain detail and the payment challenge validation.
Not charged for invalid, unsafe, non-x402 or unsupported URLs.

Input parameters:

- `url` (string, required)

### `provenpaid_methodology` (~30 tokens)

Free. How ProvenPaid computes each signal, what it does not verify, and when it charges.

Output parameters:

- `result` (string)

### `provenpaid_status` (~28 tokens)

Free. The paying wallet address, network, per-check price cap and paid checks left today.

## Common questions

### What is the ProvenPaid MCP server?

ProvenPaid is an MCP server listed in the public MCP registry as com.provenpaid/mcp. Check an x402 endpoint before your agent pays it: challenge validity and on-chain payer evidence. This page covers its PyPI package (provenpaid-mcp).

### Is the ProvenPaid MCP server safe to use?

ProvenPaid scores 87 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the ProvenPaid MCP server expose?

ProvenPaid exposes 3 tools: check_x402_endpoint, provenpaid_methodology, provenpaid_status. Their descriptions and schemas cost roughly 171 tokens of context every time the server is loaded.

### Is the ProvenPaid MCP server still maintained?

ProvenPaid is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the ProvenPaid MCP server under?

ProvenPaid declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the ProvenPaid MCP server?

VerifyMCP ran 16 checks on ProvenPaid, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to a PyPI package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
