hooddomains-mcp — Hood Domains MCP server

An MCP server that gives AI agents .hood name tools on Robinhood Chain.

Hood Domains · www.hood.domains · app · docs · npm · GitHub · X @hooddomains

There is no backend to host. This server runs on the agent's machine and talks directly to a Robinhood Chain RPC + the on-chain contracts. Read tools work out of the box; registration requires you to supply a funded key.

Tools

Configure (Claude Desktop / any MCP client)

{
  "mcpServers": {
    "hooddomains": {
      "command": "npx",
      "args": ["-y", "hooddomains-mcp"],
      "env": {
        "HOOD_RPC_URL": "https://robinhood-mainnet.g.alchemy.com/v2/YOUR_KEY"
      }
    }
  }
}

Or run locally:

cd mcp
npm install
HOOD_RPC_URL=... node index.mjs

Env

• HOOD_RPC_URL — required. A Robinhood Chain (chainId 4663) RPC endpoint. Use a server-capable key — a browser origin-allowlisted key (like the dapp's) is rejected server-side with "Unspecified origin not on whitelist".
• HOOD_PRIVATE_KEY — optional. A funded Robinhood Chain private key that enables register_name. Only set this if you want the agent to spend ETH and register names. Leave it unset for a safe, read-only server.

Notes

• register_name runs the two-step commit→reveal flow and takes ~70s (the ~60s front-run protection wait); some clients may need a longer tool timeout.
• No API keys and no Hood infrastructure are required beyond your own RPC.
• Contracts (chainId 4663): registry 0xd1a6f766577a0cd3c0f9f30b4add8623a49c5e41, registrar 0x59ac59d6a06689cc83b68dab07261cb25b8ca03e, reverse registrar 0x7614e0f829e2c7a0c093005ae887ff117d9e1df4. See /llms.txt on the site for full ABIs.
