Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: NWC_CONNECTION_STRING, PHOENIXD_URL, PHOENIXD_PASSWORD

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "boltwork": {
      "command": "uvx",
      "args": [
        "boltwork-mcp"
      ],
      "env": {
        "NWC_CONNECTION_STRING": "your-value",
        "PHOENIXD_URL": "your-value",
        "PHOENIXD_PASSWORD": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add boltwork --env NWC_CONNECTION_STRING=your-value --env PHOENIXD_URL=your-value --env PHOENIXD_PASSWORD=your-value -- uvx boltwork-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "boltwork": {
      "command": "uvx",
      "args": [
        "boltwork-mcp"
      ],
      "env": {
        "NWC_CONNECTION_STRING": "your-value",
        "PHOENIXD_URL": "your-value",
        "PHOENIXD_PASSWORD": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "boltwork": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "boltwork-mcp"
      ],
      "env": {
        "NWC_CONNECTION_STRING": "your-value",
        "PHOENIXD_URL": "your-value",
        "PHOENIXD_PASSWORD": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Common questions

Is Boltwork safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: NWC_CONNECTION_STRING, PHOENIXD_PASSWORD

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.12) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

boltwork-mcp

MCP server for Boltwork — AI services that pay for themselves via Bitcoin Lightning.

Give your AI agent PDF summarisation, code review, translation, web extraction, document comparison, and persistent memory — all paid autonomously in sats. No API keys. No subscriptions. No accounts.

What this is

Boltwork is a pay-per-call AI services API that uses the L402 protocol — your agent makes a request, receives a Lightning invoice, pays it automatically, and gets the result back. No human involved.

This package wraps Boltwork as an MCP server so any MCP-compatible AI (Claude, Cursor, Windsurf, etc.) can use it as a tool — with payments handled transparently in the background.

Try it immediately — no wallet required

Two tools work right now with zero setup:

"mcpServers": { "boltwork": { "command": "uvx", "args": ["boltwork-mcp"], "env": {} } } }

Then ask your AI:

"Use trial_review_code to review this: def add(a, b): return a + b"

"Use trial_summarise to summarise this: "

Real AI results instantly. No Lightning wallet. No setup. Rate limited to 5 calls/hour.

Install

pip install boltwork-mcp

If using NWC (Alby, Mutiny, Coinos, etc.):

pip install "boltwork-mcp[nwc]"

Or use directly with uvx — no install needed:

uvx boltwork-mcp

Setup — pick a wallet

Four wallet backends are supported. Pick whichever fits your setup:

Option A — NWC / Nostr Wallet Connect (easiest)

Works with Alby, Mutiny Wallet, Coinos, Primal, Cashu.me, and any NWC-compatible wallet.

Get a connection string:

Alby — go to nwc.getalby.com, create a budget, copy the string
Mutiny — Settings → Connections → Add connection
Coinos — coinos.io → Settings → Nostr Wallet Connect

Add to your MCP config:

"mcpServers": { "boltwork": { "command": "uvx", "args": ["boltwork-mcp"], "env": { "NWC_CONNECTION_STRING": "nostr+walletconnect://your-string-here" } } } }

Requires: pip install "boltwork-mcp[nwc]"

Option B — LNbits

Works with lnbits.com or any self-hosted LNbits instance. Popular with BTCPay Server users and home node operators.

Create a wallet at lnbits.com or your instance
Go to API info → copy your Invoice/read key

"mcpServers": { "boltwork": { "command": "uvx", "args": ["boltwork-mcp"], "env": { "LNBITS_URL": "https://lnbits.com", "LNBITS_API_KEY": "your-invoice-key-here" } } } }

For self-hosted: set LNBITS_URL to your instance URL (e.g. https://lnbits.yourdomain.com).

Option C — Strike

Works with a Strike account. Custodial, simple API key setup. Good for US users or anyone who already uses Strike.

Create an account at strike.me
Go to dashboard.strike.me/developers/api-keys → create an API key

"mcpServers": { "boltwork": { "command": "uvx", "args": ["boltwork-mcp"], "env": { "STRIKE_API_KEY": "your-api-key-here" } } } }

Option D — Phoenixd

Works with Phoenixd — ACINQ's self-hosted Lightning node. Simple REST API, no channel management.

Install Phoenixd: phoenix.acinq.co/server
Get your HTTP password from the Phoenixd config

"mcpServers": { "boltwork": { "command": "uvx", "args": ["boltwork-mcp"], "env": { "PHOENIXD_URL": "http://localhost:9740", "PHOENIXD_PASSWORD": "your-password-here" } } } }

Payment flow

When your agent calls a paid tool:

boltwork-mcp calls the Boltwork API
Receives HTTP 402 with a Lightning invoice
Pays the invoice automatically using your configured wallet
Retries the request with the payment proof
Returns the result to your agent

Your agent never sees this — it just gets the result.
