Overview

What is HashA2A?

HashA2A is a decentralized agent-to-agent data marketplace running on Hedera mainnet. It provides AI agents with verified, multi-oracle intelligence via HBAR (HIP-991) or USDC (x402/AP2) micropayments, and includes tools for price feeds, arbitrage scanning, prediction markets, deep research, and Hedera enterprise operations.

How to use HashA2A?

Install with a single command: npx hasha2a-mcp-client add (auto-detects Claude Desktop, Cursor, Windsurf) or use the shell script curl -fsSL https://raw.githubusercontent.com/ymiydev-prog/HashA2A/main/scripts/install-mcp.sh | bash. Connect to the server URL https://hasha2a.com/mcp. Authenticate via HBAR (HIP-991 auto-fees) or USDC (x402/Circle Gateway, gasless). Transport is Streamable HTTP (remote) or stdio via mcp-remote.

How do I install HashA2A?

Install with npx hasha2a-mcp-client add (NPM, recommended) or the shell script (no Node.js needed). You can also deploy locally with docker compose up -d and use the server at http://localhost:8080/mcp.

What transport protocols does HashA2A support?

HashA2A supports Streamable HTTP (remote) and stdio via mcp-remote. For A2A, it offers JSON-RPC 2.0 with SSE streaming, task lifecycle, context passing, and AP2 mandates.

Is there any runtime dependency?

The NPM install requires Node.js. The shell script method does not. Docker deployment requires Docker. The enterprise plugin runs in an isolated Python venv via the hedera-agent-kit bridge.
