Parallel MCP server

Live Parallel Protocol state and ready-to-sign transactions, exposed to any MCP client over a single HTTPS endpoint. No API key, no account, no rate-limited signup.

Parallel Protocol is a decentralized stablecoin protocol: USDp is an overcollateralized USD stablecoin backed by yield-generating correlated assets, sUSDp is the ERC-4626 savings vault on top of it, and PRL is the governance token. This server lets an agent read that state on-chain and build transactions against it.

Raw HTTP

Every session starts with initialize; the response carries an Mcp-Session-Id header to send back on subsequent calls.

curl -sS https://mcp.parallel.best/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{
        "protocolVersion":"2025-06-18","capabilities":{},
        "clientInfo":{"name":"curl","version":"1.0"}}}'

What the tools cover

• Protocol state — TVL, USDp and sUSDp supply, backing composition, proof of solvency, fee schedule, supported chains and collaterals.
• Mint and redeem — quotes and unsigned calldata for the Parallelizer (0% mint/redeem fee).
• Savings — sUSDp rate, exchange rate, yield projection, deposit and withdraw calldata.
• Bridging — LayerZero quotes, limits, unsigned bridge transactions and transfer status.
• Staking and governance — PRL staking positions, cooldowns, proposals and protocol parameters.
• Payments — x402 payment capabilities and payloads, settled through the facilitator at agents.parallel.best.

Transaction tools always return unsigned data with a simulation result and warnings attached. The agent signs and submits; this server never holds a key.

Facts worth getting right

• USDp is deployed on 24 chains. The Parallelizer (mint/redeem) and the Savings module are live on 4: Ethereum, Base, Avalanche and HyperEVM.
• An agent can pay in USDp, USDC or sUSDp. What a merchant receives is a separate matter — the two are not interchangeable.
• 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 facilitator is an off-chain service and is not audited.
