MPP Protocol

Score 58 · Grade -- · ★★☆☆☆

The open protocol for machine-to-machine payments. HTTP 402 based, co-developed by Tempo Labs and Stripe. Enables AI agents to pay for services automatically.

Overview

MPP Protocol is an attempt to standardize machine-to-machine payments using the HTTP 402 Payment Required status code. It aims to give AI agents a native way to handle financial transactions for services, which is a necessary step for an autonomous economy.

Best For

Developers building autonomous AI agents that need to programmatically purchase API access or compute resources from other services.

Verdict

MPP Protocol addresses a critical gap in the AI ecosystem, but it currently lacks the machine-readable infrastructure required for true autonomy. If the team adds agent-specific discovery files and standardizes their API access, this could become a foundational piece of the agentic web.
