Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to maximumsats.com. It runs from a package rather than a hosted endpoint, so there is no endpoint to match against that domain.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Local MCP server for Bitcoin AI tools and Nostr Web of Trust scoring, with paid calls settled over Lightning L402.

What you can do: Provides twelve tools: Bitcoin and Lightning question answering, text-to-image generation, and a set of Nostr Web of Trust utilities such as trust scoring, Sybil checks, trust paths, network health, follow quality, trust circles, anomaly detection, link prediction, provider comparison, and influence simulation. Paid AI endpoints use an L402 flow where a request returns a Lightning invoice and a payment hash, and the call is retried with the payment hash in the Authorization header. Web of Trust tools are described as free up to 50 calls per day.
When to use it: Useful when an assistant needs Bitcoin or Lightning answers, generated images, or reputation and Sybil-resistance signals for Nostr public keys, for example before paying a bounty or judging an account's trustworthiness. Also relevant if you want to experiment with pay-per-call MCP tools settled over Lightning.
Requirements: Runs locally over stdio, started with npx maximumsats-mcp, so Node.js and network access to the provider's endpoints are needed. Paid tools require a Lightning wallet able to pay the returned invoice and the payment hash from that invoice for the retry. No accounts, API keys, or environment variables are declared.

Before you install

Paid tools spend real money in satoshis: ask_bitcoin is listed at 21 sats and generate_image at 100 sats per call. The L402 retry sends the payment hash in the Authorization header, and prompts, images, invoices, and Nostr identifiers are sent to third-party endpoints at maximumsats.com and wot.klabo.world. Payments on Lightning are generally final, so verify the invoice and amount before paying.

Installation

In SourceWeft

Open Maximum Sats in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

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:

bash

# 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":{...}}

# 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

bash

curl https://maximumsats.com/api/wot/npub1...# Returns: {"score": 45, "rank": 1234, "percentile": 95.5}

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):

javascript

// 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: { ... } }

// 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.
