@parad0x_labs/null-mcp

MCP server for Web0 .null domains on Solana. Lets an AI agent resolve, buy (register), and bid on .null domain auctions — returning unsigned transactions so the agent's own wallet signs. The server never holds a private key.

All transaction layouts are verified against the live mainnet programs:

• null_registrar — H4wbFJucY9shJt95N8Bra532Z4nnkKhGEfqWvLcYfuDm
• null-auction — 7uxLhqLzkEzPpkvdmTwqgL3g66yq2aMBS5QgcjaZZEaw

Run

npx @parad0x_labs/null-mcp

Or wire it into an MCP client (Claude Desktop, etc.):

{
  "mcpServers": {
    "null-mcp": {
      "command": "npx",
      "args": ["-y", "@parad0x_labs/null-mcp"]
    }
  }
}

Tools

| Tool | What it does | |---|---| | resolve_null_domain | Read a name's full on-chain record (owner, Arweave content, x402 endpoint, Dark Passport) | | fetch_null_content | Fetch the site the name points to (Arweave) | | register_null_domain | Buy a name → returns an unsigned Register transaction | | get_null_auction | Read live auction state for a name | | bid_null_auction | Bid SOL/NULL on an auction → returns an unsigned PlaceBid transaction |

Bring-your-own-signer

register_null_domain and bid_null_auction return base64 unsigned transactions. The agent (or its wallet) signs and submits them. This package builds and reads; it does not sign, hold keys, or move funds on its own.
