Deploy AI agents on-chain from any MCP client or your browser: mint a Metaplex Core asset and register its EIP-8004 identity in the Metaplex Agent Registry on Solana. By three.ws.
Deploy AI agents on-chain into the Metaplex Agent Registry on Solana, from any MCP client.
One flow mints a Metaplex Core asset and registers its EIP-8004 agent identity (a single atomic transaction when it fits Solana's 1232-byte limit, create + register in sequence otherwise, exactly how the Genesis 333 landed), so the agent shows up on metaplex.com/agents with its own built-in wallet, reputation surface, and explorer pages. The default output reproduces the exact shape of the three.ws Genesis 333 mints, verified byte-for-byte against the live assets:
- asset metadata as a self-contained data:application/json;base64 URI (name, image, animationurl GLB) - Royalties plugin (5% to the owner), VerifiedCreators (the signing wallet), ImmutableMetadata - AgentIdentity plugin carrying the eip-8004registration-v1 document (model.uri, active, x402Support, registrations, supportedTrust)
- Agents sign with their own keypair (SOLANASECRETKEY): mintonchainagent. - People sign with Phantom, Solflare, Backpack, Ledger, or any Solana wallet: prepareagentmint builds the transaction, the wallet signs it, sendsignedtransaction broadcasts it. No key ever touches the server.
A mainnet deploy pays a flat 0.02 SOL fee, in the same transaction as the mint, and that fee funds $THREE buybacks. Hold $THREE and it halves, then disappears; devnet never pays it. Every preview shows the number and its recipient before anything is signed. See $THREE: the deploy fee and the holder waiver.
