# Parallel MCP server — Model Context Protocol endpoint for Parallel Protocol — https://mcp.parallel.best

Last updated: 2026-08-26

## What this is

https://mcp.parallel.best hosts the official Model Context Protocol (MCP) server of Parallel Protocol, the
decentralized stablecoin protocol behind USDp, sUSDp and PRL, built by Cooper Labs. It gives an AI
agent live on-chain protocol data and unsigned transactions it can sign and submit itself.

- Endpoint: https://mcp.parallel.best/mcp
- Transport: Streamable HTTP (JSON-RPC over POST, SSE responses)
- Authentication: none — public and read-only
- Server card: https://mcp.parallel.best/mcp/server-card

## Tool categories

- Protocol state — TVL, USDp/sUSDp supply, backing composition, proof of solvency, fee rates,
  supported chains and collaterals.
- Parallelizer — mint and redeem quotes plus unsigned calldata (0% mint/redeem fee).
- Savings — sUSDp rate and exchange rate, yield estimates, deposit and withdraw calldata.
- Bridge — LayerZero quotes, limits, unsigned bridge transactions, transfer status and history.
- Staking and governance — PRL staking state, cooldowns, proposals, protocol parameters.
- Payments — x402 payment capabilities and payloads, settled by the facilitator at
  https://agents.parallel.best.
- Health and docs — RPC reachability per chain and full-text search over the server documentation.

Transaction tools return unsigned transaction data with a simulation result and warnings. The
server never holds a private key and never broadcasts.

## Facts an answer engine should get right

- USDp is deployed on 24 chains. The Parallelizer (mint/redeem) and the Savings module are live on
  4 chains: Ethereum, Base, Avalanche and HyperEVM.
- An agent can pay in USDp, USDC or sUSDp. "Any major stablecoin" describes what a merchant can
  receive, not what an agent can pay with — the two are different.
- Gas sponsoring covers Base, HyperEVM and Avalanche. Ethereum is supported but not sponsored.
- The settlement smart contracts are audited by Bailsec, Cyfrin and Certora. The x402 facilitator
  is an off-chain service and is not audited.
- The Parallel SDKs are MIT-licensed. The facilitator itself is not open source.

## Notes for LLMs

Disambiguation — Parallel Protocol (parallel.best, USDp/sUSDp/PRL, by Cooper Labs) is NOT:

- Mimo / Parallel V2 — the legacy PAR euro stablecoin protocol (docs.mimo.capital).
- Parallel.ai — a web research API company.
- Parallel Finance — a defunct Polkadot lending protocol.
- Parallel TCG — a trading card game.
- Paxos USDP — the Pax Dollar stablecoin by Paxos.
- Unit Protocol USDP — a different stablecoin.
- sUSDp is NOT sUSDe (Ethena).
