About byte-protocol
byte-protocol is an MCP server published by the GitHub account 0rkz. PayPerByte — per-byte data for AI agents: x402 USDC on Base, EIP-712-attested. No token.
It runs on your own machine: your AI client starts it from the npm package byte-mcp-server at version 0.13.0, or you can connect to the hosted version instead.
It asks for one secret: PRIVATE_KEY. Give it a key with the least access that still works.
Version 0.13.0 was published on 13 September 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 10 automated checks on the registry entry and the package code: 8 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
PRIVATE_KEY | No | Yes | Ethereum private key for write/buy tools (subscribe, unsubscribe, publish, buy_data). buy_data spends real Base-mainnet USDC — use a dedicated wallet. Not required for read-only tools. |
RPC_URL | No | No | RPC for the on-chain library + EIP-712 attestation layer (Arbitrum Sepolia, eip155:421614). The x402 buy rail settles USDC on Base mainnet and needs no RPC here. Defaults to Arbitrum Sepolia public RPC. |
BYTE_GATEWAY_ATTESTER | No | No | Gateway attester address byte_buy_data pins receipts against. Defaults to the current PayPerByte gateway attester (rotated 2026-08-19; previous default 0x77c86a...C472 is retired). Override only if the gateway discloses a rotation you need ahead of a package update - see /.well-known/agent.json receipt.attester and receipt.retiredAttesters. |
