Tempo launches MPP agent directory
Tempo rolled out MPP, a directory of 100+ AI/agent services (including Alchemy, Dune, fal.ai) designed to be payable autonomously without API keys, aiming to simplify integrations for on‑chain agents (x.com). That creates a standardized plumbing for trading and analytics agents to access paid tooling on demand.
Tempo activated its mainnet and launched the Machine Payments Protocol (MPP) on March 18, 2026. (tempo.xyz) MPP was co‑authored with Stripe and designed to be rail‑agnostic, supporting stablecoins, card rails and Bitcoin Lightning as settlement options. (docs.tempo.xyz) Tempo’s launch materials list design partners and enterprise collaborators including Anthropic, OpenAI, Visa, Mastercard and Shopify that helped test agent payment flows. (tempo.xyz) Developer tooling enables ephemeral wallets and a Tempo CLI that previews costs and funds agent spending limits, while MPP servers return payment receipts to reconcile spend. (docs.tempo.xyz) Dune’s MPP integration demonstrates the flow in practice: an MPP‑aware fetch intercepts an HTTP 402, opens a Tempo payment channel, retries the request with a credential, and surfaces a base64 payment receipt header. (docs.dune.com) Alchemy published a blog confirming full support for Tempo’s MPP on launch day, noting enterprise‑grade infrastructure and the ability to settle paid API calls with stablecoins on Tempo. (alchemy.com) Tempo reported a $500 million Series A at roughly a $5 billion valuation in October 2025, led by Greenoaks and Thrive Capital, funding that underpins its partner integrations and go‑to‑market push.
