Runs npx -y @piprail/mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the PipRail repository's README, as published. We do not edit it. Read it on GitHub

Let any HTTP endpoint charge for itself, and any agent pay for itself — across every major chain, in a couple of lines.

Website · Documentation · npm

PipRail implements the open x402 "402 Payment Required" standard with no backend, no database, no account, no API key, and no fee. Payments settle straight into your wallet, verified locally against your own RPC — across every major EVM chain plus Solana, TON, Tron, NEAR, Sui, Aptos, Algorand, Stellar & the XRP Ledger. Self-custodial throughout.

How a payment moves

The middle is the difference. A traditional processor holds the money in transit, takes days to release it, and can freeze or reverse it. PipRail removes the middle entirely — the agent pays the merchant's wallet directly, the merchant verifies it locally against their own RPC, and it settles in one transaction at 0% fee, self-custodial end to end.  See it on piprail.com →

📊 The pitch deck

Opens right here in your browser — no download, GitHub renders it inline. 16 slides · every stat sourced in the speaker notes.

The whole thesis in one read: why agent payments are happening now, why chain & token fragmentation is the enemy, and how a single chain: parameter turns PipRail into the universal adapter. The payment path is 0% forever — the moat and the distribution; value accrues to the layer around the free rail, never the rail itself.
