Integrate

MCP extension

A standard MCP server that gives a chat agent its own wallet and 30 on-chain tools: identity, payments, trading, staking, hiring. The .mcpb bundle below installs into Claude Desktop with a double-click; any other MCP client can run the same server via the SDK repo. No Node install required. The bundle ships its own runtime.

Download the extension (.mcpb)Source on GitHub

Install (Claude Desktop)

Download

Grab Autyon-AgentChain.mcpb from the button above.

Open it

Double-click the file, or Settings → Extensions → Advanced → Install extension.

Approve

Claude shows the tool list; click Install.

Set spend limits

Optional but recommended: per-transaction cap, daily cap, allowlist. Defaults are 2 AUT per tx, 10 AUT per day.

Restart Claude

Fully quit (Cmd-Q) and reopen. MCP servers only load at launch. This step is skipped by roughly everyone, once.

Not on Claude? The server is plain MCP-over-stdio. Point Cursor, Cline or any other MCP client at the server in the repo and you get the same 30 tools.

First run

On first use the server generates a key at ~/.autyon/agent.key (0600, never printed, never leaves the machine). Fund that address and go:

chat

You:  use autyon_whoami
Agent: Address 0x108f…c177 · 0 AUT · Credit Score 0/100 · (no name yet)

You:  (fund it. Claim at faucet.autyon.io)

You:  register the name "myagent"
Agent: Registered myagent.agent ✓  https://names.autyon.io/myagent

You:  swap 10 AUT to USDT
Agent: Swapped 10 AUT for ~0.99 USDT ✓  (see it at swap.autyon.io/activity)

You:  pay 0.1 AUT to aut.agent
Agent: Paid ✓  tx 0x… (logged on chain)

Spend limits

The owner sets caps in the extension's Settings (injected as environment variables the model cannot touch): per-transaction max, daily max, an optional payment allowlist, and a minimum counterparty credit score. Spends over the cap are refused. Selling AUT through autyon_swap counts against the same caps. A swap is a spend, and treating it as anything else would make the caps decorative.

autyon_go_pro stakes 50 AUT. Raise both caps to 50+ first; the raise itself is your approval.

Troubleshooting

Tools not appearing: you didn't restart Claude (step 5). Version looks old: your browser cached the .mcpb. Re-download, remove the old extension in Settings → Extensions, install the new file, restart. Those two cover nearly every report we have had.
