Maximum Sats MCP Server
MCP server for Bitcoin AI tools and Nostr Web of Trust scoring. Pay-per-use via Lightning L402.
Why MaximumSats?
As MCP servers proliferate, a critical question emerges: How do we secure and monetize MCP API access in a decentralized way?
MaximumSats delivers:
- L402 Payment Endpoints — Every API call can require payment in satoshis
- Web of Trust (WoT) Scoring — Sybil-resistant reputation for Nostr users
- Nostr ID Utilities — Decoding/encoding npub, note, nprofile, nevent, naddr, and more
Use Cases
- Bounty Platforms — Pay hunters per task, prevent sybil with WoT
- AI Agent Marketplaces — Monetize MCP tools per-call
- Data Feeds — Secure oracle data with L402
- Reputation Systems — WoT-powered trust scoring

Security & Governance Features
MaximumSats is purpose-built for the Secure & Govern MCP track:
1. Paid API Access Control — One Payment, One Retry
Every endpoint can be gated behind payment. The L402 flow is simple:
# Request returns HTTP 402 with Lightning invoicecurl -X POST https://maximumsats.com/api/dvm \ -H "Content-Type: application/json" \ -d '{"prompt":"hello"}'
Returns: {"error":"Payment required","payment_request":"lnbc21...","payment_hash":"abc123","amount_sats":21}
Pay the invoice in your Lightning wallet, then retry with payment_hash in Authorization header:
curl -X POST https://maximumsats.com/api/dvm \ -H "Content-Type: application/json" \ -H "Authorization: abc123" \ -d '{"prompt":"hello"}'
Returns: {"status":"success","data":{...}}
2. Sybil Resistance with WoT
The WoT endpoint scores Nostr pubkeys based on their network position — valuable for:
- Bounty platforms preventing fake accounts
- Voting systems needing sybil resistance
- Reputation engines
curl https://maximumsats.com/api/wot/npub1...Returns: {"score": 45, "rank": 1234, "percentile": 95.5}
3. No Middleman — Direct Lightning
- Instant settlement on Lightning Network
- No subscriptions, pay per request
- Pseudonymous, no KYC required
Technical Implementation
MaximumSats uses the L402 protocol (Lightning HTTP 402):
// Challenge response includes invoice{ status: 402, error: "Payment required", invoice: "lnbc...", amount_sats: 21 }
// After payment, include payment_hash in retry { status: 402, error: "Payment required", payment_hash: "abc123..." }
// Successful response after payment verification { status: 200, data: { ... } }
All payment flows through Lightning Network — no blockchain bloat.
