Enables AI agents to create permanent content on the Bitcoin SV blockchain using 1SatOrdinals, including inscriptions (HTML, JSON, text, images), domain registration, payments/transfers, and wallet management.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@ORDnet MCP Server Inscribe my blog post as an HTML page on Bitcoin SV"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Enable AI agents to create Web3 content on Bitcoin SV blockchain
ORDnet MCP Server enables AI agents (Claude, GPT, etc.) to create permanent, censorship-resistant content on the Bitcoin SV blockchain using the 1SatOrdinals protocol. This is a key component of the freedom of speech infrastructure - allowing AI to autonomously publish Web3 content.
43 MCP Tools for complete blockchain content creation, payments and transfers
BRC-100 aligned identity (v3.0): ordnet_identity, ordnet_sign_message, ordnet_verify_message, ordnet_derive_payment_address — agent identity, off-chain signing, and per-invoice payment-address derivation as the foundation for x402
Agent payments: ordnet_send (P2PKH + optional OP_RETURN reference, miner fee only — x402-ready), ordnet_transfer for ordinals/domains (1SatOrdinals input-0/output-0 semantics, outpoint verified via own node)
Binary inscriptions via ordnet_inscribe_binary (base64 → bytes untouched); BSVmap tile claims via ordnet_bsvmap_inscribe
Agent conveniences: ordnet_tx_status (confirmations via own node), ordnet_price (via own CoinGecko proxy)
3 MCP Prompts (prompts/list): inscribe-website, register-domain, agent-payment
1SatOrdinals inscriptions (HTML, JSON, text, images, etc.)
SNS/OPNS domain registration (.sats, .btc, .bsv, etc.)
3-tier wallet security (env vars → encrypted → plaintext; plaintext-WIF tools are disabled on the HTTP transport)
Agent safety layer: tx simulation via ORDnet's own node + spend limits with operator-set hard ceilings (fail-closed)
HTTP transport with mandatory bearer auth (ORDNET_MCP_AUTH_TOKEN, server refuses to start without it)
Fee structure identical to ordmail-v10-standalone-026.html: 396 sats service fees across 11 outputs / 10 addresses, miner fee 0.15 sat/byte (min. 200 sats)

Wallet and spend-policy state are per server process, not per client session. Run the HTTP transport for a single trusted agent/team behind the auth token, not as a public multi-tenant service.
Balance and UTXO lookups use ORDnet's OWN address index (ordnet-utxo, port 7002, every UTXO node-verified) since v2.5; WhatsOnChain is a connectivity fallback only. New tools in v2.5: ordnet_index_health, ordnet_address_watch.
UTXO selection skips 1-sat UTXOs as ordinal protection and combines multiple inputs when needed.
