No token.\n\nThe current version, v0.12.3, was published to the official MCP registry on 2026-09-03. It is distributed as byte-mcp-server on npm and as a hosted remote over streamable-http, filed under Other by this index, and declares 3 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; [the index's current counts](/stats) put this record in context.\n\n## Using io.github.0rkz/byte-protocol in Claude, Cursor, Gemini CLI, Cline, or Zed?\n\nMCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and **HOLDs the call** when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use **Install this server** for that).\n\nRewrites your MCP host config so each server launches behind the gate.

A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory.

Not required for read-only tools.\n\n`RPC_URL`\n\nRPC 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.\n\n`BYTE_GATEWAY_ATTESTER`\n\nGateway 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.\n\n[methodology](/methodology)\n\n[AgentRoamai.agentroam/agentroam](/server/ai-agentroam-agentroam)\n\nBuy travel eSIMs, gift cards and mobile top-ups with crypto — user confirms before any order.\n\n[Authoryzeai.authoryze/authoryze](/server/ai-authoryze-authoryze)\n\nGive your AI agent a spending limit: approval controls and single-use virtual cards.\n\n[io.github.0x-devc/novai-mcp-serverio.github.0x-devc/novai-mcp-server](/server/io-github-0x-devc-novai-mcp-server)\n\nRead-only MCP server for querying the live NOVAI blockchain over its public JSON-RPC endpoint.", "url": "https://wpnews.pro/news/io-github-0rkz-byte-protocol-io-github-0rkz-byte-protocol-0-12-3", "canonical_source": "https://mcpindex.ai/server/io-github-0rkz-byte-protocol", "published_at": "2026-09-03 00:04:38+00:00", "updated_at": "2026-09-03 00:51:41.014524+00:00", "lang": "en", "topics": ["ai-agents", "ai-infrastructure", "ai-tools"], "entities": ["io.github.0rkz/byte-protocol", "byte-mcp-server", "MCP registry", "Base", "EIP-712", "x402", "mcpindex"], "alternates": {"html": "https://wpnews.pro/news/io-github-0rkz-byte-protocol-io-github-0rkz-byte-protocol-0-12-3", "markdown": "https://wpnews.pro/news/io-github-0rkz-byte-protocol-io-github-0rkz-byte-protocol-0-12-3.md", "text": "https://wpnews.pro/news/io-github-0rkz-byte-protocol-io-github-0rkz-byte-protocol-0-12-3.txt", "jsonld": "https://wpnews.pro/news/io-github-0rkz-byte-protocol-io-github-0rkz-byte-protocol-0-12-3.jsonld"}}
