Hedera's hosted Network MCP lets Claude Code, Codex, and Cursor build testnet transactions you sign in your wallet

Add one URL (https://agentic-testnet-mcp.hedera.com/mcp) and sign in with a HashPack or Kabila wallet over OAuth, and your agent can transfer HBAR, mint tokens, deploy contracts, and post consensus messages, but the server holds no keys and every transaction waits for your wallet approval. It's testnet only, with no spend caps, so the wallet prompt is your only guardrail (CryptoCompass).
