Hedera Launches Network MCP on Testnet for AI Blockchain Actions
2026-10-23
Hedera Network MCP is a hosted Model Context Protocol server now live on testnet that lets AI tools such as Claude Code, Codex, Cursor and ChatGPT connect to the Hedera network through one standard endpoint, build transactions and hand them to a user’s wallet for approval.
The release moves Hedera AI beyond documentation helpers and toward agents that can actually act. It lands alongside the Agent Accounts roadmap and a mainnet upgrade reported this week. Here is what launched, how it works and what to watch next.
Key Takeaways
Hedera Network MCP is live on testnet. AI tools connect through one endpoint and use more than 40 tools to send HBAR, create tokens, manage allowances and read network data.
The design is non-custodial. The server holds no keys and never submits transactions, so nothing settles until the user signs in their own wallet.
Mainnet is not part of this release. Agent Accounts and a Payments MCP are the next steps, with a mainnet target of Q2 2027 that depends on audits and legal agreements.
What Is Hedera Network MCP? The Short Answer
Hedera Network MCP is a hosted Model Context Protocol server that lets AI tools build Hedera transactions and read network data through one connection, while the user's own wallet signs everything. It is a managed instance of the Hedera Agent Kit, so developers do not need to run any infrastructure.
The server connects to Hedera testnet only for now. Anyone who needs mainnet today must run the self-hosted Hedera Agent Kit MCP server instead.
Model Context Protocol: A Common Plug for AI Tools
Model Context Protocol, or MCP, is an open standard introduced by Anthropic that lets AI apps connect to outside tools in a consistent way. Think of it as a universal plug. Once a service supports MCP, any compatible AI client can discover its tools and use them.
Before this, developers had to wire up SDKs by hand for every project. With Network MCP, an agent can find Hedera tools on its own and call them from a chat or a coding session. That is the core idea behind the agentic Web and the wider Web3 AI trend.
Key Players Behind the Hedera AI Launch
Hedera is a public proof of stake network that uses hashgraph consensus, and HBAR is its native token. Anthropic created MCP, while Claude Code, Codex, Cursor and ChatGPT are the AI clients named for the new connection. Wallets such as HashPack and Kabila handle approvals.
Two other pieces round out the stack. Hedera's Docs MCP is already running and feeds live documentation to coding agents so they stop inventing API calls. A Payments MCP that lets an assistant pay within set limits is listed as coming soon. Hedera also maintains an open source Skills marketplace for AI coding agents.
How the Non-Custodial Flow Works
The model keeps the human in control of every state change. Read requests return instantly, while anything that changes the network passes through the user's wallet.
Sign In With Your Wallet
Instead of a password, users sign in with a wallet through OAuth 2.1. They connect via WalletConnect, approve a sign-in message and return to their AI tool. That message moves no funds. It only proves ownership of the account, and no keys are shared with the server.
Build, Approve and Confirm
When an agent wants to act, the server builds and freezes the transaction, then delivers it to the wallet. The user has about 180 seconds to approve. The agent then checks the status, which moves from awaiting approval to confirming to executed once the mirror node confirms it.

What AI Agents Can Do on Hedera Today
The Network MCP includes the core plugins from the Hedera Agent Kit. Through an AI tool, users can cover five main areas.
Sample prompts include checking an HBAR balance, reading messages on a topic or creating a demo token. Hedera Consensus Service tools also make it easy to test AI agents that log their actions on a public record.
How to Connect Claude Code, Cursor and ChatGPT to Hedera
Before you start, create a free testnet account in the Hedera Developer Portal and load it into a wallet such as HashPack or Kabila. The endpoint for every client is https://agentic-testnet-mcp.hedera.com/mcp, and there is no API key or header to set.
Claude Code
Run this command, then use /mcp inside Claude Code to authenticate with your wallet.
claude mcp add --transport http hedera-testnet https://agentic-testnet-mcp.hedera.com/mcpCursor and Codex
In Cursor, add an entry with the endpoint URL to mcp.json, then click Authenticate. For Codex CLI, one command does the job.
codex mcp add hedera-testnet --url https://agentic-testnet-mcp.hedera.com/mcpChatGPT Desktop
Open Settings, then Plugins, then the MCPs tab, and add a streamable HTTP server with the same URL. Authenticate with your wallet and restart the app. Note that MCP servers only work from the Work tab, not the normal chat tab. Claude Desktop and claude.ai also work through the custom connector settings.
How to Buy Hedera Hashgraph (HBAR) Safely in 2026
Interpretation Cheat Sheet: What This Launch Means
Use this quick guide to read the news without overstating it.
Testnet only: no real funds are at risk, and no mainnet activity comes from this release.
40+ tools: agents can do real work, not only read documentation.
Wallet signing: a human approves every state change, which is the main safety feature.
No spend policies yet: there are no daily caps or recipient allowlists, so the wallet prompt is the only control.
Single-key accounts only: threshold and key-list accounts cannot sign in.
Limited wallet decoding: smart contract calls and file operations cannot be fully read in a wallet, so review the agent's summary carefully.
Roadmap: Agent Accounts, Payments MCP and Mainnet
Hedera announced Agent Accounts on October 13. They are programmable, non-custodial spending accounts funded from a user's existing wallet and created separately for each agent. Rules are enforced on-chain, payments can use HBAR, USDC or other Hedera tokens, and the design is compatible with x402. Every action is recorded on the Hedera Consensus Service.
The stated timeline is a limited partner testnet in Q4 2026, a public testnet in Q1 2027 and a mainnet target in Q2 2027. Those dates depend on security audits and legal agreements. The Payments MCP is expected to pair with Agent Accounts, so users can set allowances and policies for a paired agent and keep an audit trail.
What It Means for HBAR and the AI Crypto Narrative
This launch is not a direct price catalyst for HBAR. It runs on testnet, and real demand would only follow if agents begin transacting on mainnet. Reports this week also noted that the Hedera mainnet upgrade to version 0.78.1 completed, though market moves around the news were quiet.
The bigger story is positioning. Hedera is betting that AI agents will need a safe way to pay and act onchain. Readers following the AI and crypto theme can also use Bitrue AI for data-driven market analysis alongside this kind of HBAR news.
Summary
Hedera Network MCP is a careful first step. It gives developers a clean, standard way to connect AI coding agents to the network, and its wallet-first design avoids the biggest risk of letting software hold keys.
The limits are just as clear. It is testnet only, it has no spending controls yet and some transactions are hard to verify in a wallet. The real test comes when Agent Accounts and mainnet support arrive.
