This server wires up Bitcoin and Lightning Network tools with native L402 micropayment gating. You get AI endpoints like ask_bitcoin and generate_image that charge per request in satoshis, plus a full suite of Nostr Web of Trust scoring tools for reputation checks and sybil detection. Every API call can require Lightning payment via the L402 protocol: you hit an endpoint, get a 402 with an invoice, pay it, then retry with the payment hash. The WoT endpoints are free up to 50 calls per day and cover scoring, trust paths, network analysis, and anomaly detection across 51,000+ Nostr nodes. Reach for this when you need pay-per-use APIs or reputation gating without subscriptions or middlemen.

Maximum Sats MCP Server

MCP server for Bitcoin AI tools and Nostr Web of Trust scoring. Pay-per-use via Lightning L402.

Why MaximumSats?

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
