mpp SKILL.md skillA

mpp from tenequm/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add tenequm/skills/mpp@v0.10.2

Pins v0.10.2 in mdr.lock. Pin the fingerprint instead.

Build with MPP (Machine Payments Protocol), open machine-to-machine payments over HTTP 402. Use for paid APIs, payment-gated endpoints, agent payment flows, MCP tool payments, or metered billing. Covers mppx (TS), pympp, and mpp Rust SDKs.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# MPP - Machine Payments Protocol

MPP is an open protocol (co-authored by Tempo and Stripe) that standardizes HTTP `402 Payment Required` for machine-to-machine payments. Clients pay in the same HTTP request - no accounts, API keys, or checkout flows needed.

The core protocol spec is submitted to the IETF as the [Payment HTTP Authentication Scheme](https://datatracker.ietf.org/doc/draft-ryan-httpauth-payment/).

Code in this skill uses placeholder token names (`<USDC_TEMPO_MAINNET>`, `<PATHUSD_TESTNET>`); the real addresses live in the [Tempo documentation](https://docs.tempo.xyz) and `references/tempo-method.md`.

## Core Architecture

Three primitives power every MPP payment:

1. **Challenge** - server-issued payment requirement (in `WWW-Authenticate: Payment` header)
2. **Credential** - client-submitted payment proof (in `Authorization: Payment` header)
3. **Receipt** - server confirmation of successful payment (in `Payment-Receipt` header)

## Payment Methods & Intents

MPP is payment-method agnostic. Each method defines its own settlement rail:

| Method | Rail | SDK Package | Status |
|--------|------|-------------|--------|

How to install

The exact contents, by fingerprint
mdr add tenequm/skills/mpp@sha256:45e473e518fce7d9

The line at the top of this page pins the label v0.10.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
