Mcp Server
Gives your AI agent a non-custodial Bitcoin Lightning wallet with instant payments and L402/X402 protocol support for accessing paid APIs. Exposes tools for paying invoices, keysend transfers, Lightning addresses, and automatic L402 API payments that handle both Lightning and USDC on Base. Includes operator/agent hierarchy for managing multiple agents with budget limits, plus webhooks for payment notifications and full transaction export. Works as both an MCP server for Claude Desktop and a CLI tool for any agent framework with shell access. Ships with free sats for first-time users and supports LNURL auth and withdrawals. Reach for this when you need agents that can autonomously pay for services or transfer value without custody risk.

Lightning Wallet
Give your AI agent a Bitcoin wallet. One MCP server plus a CLI. Works with Claude Code, Cursor, Windsurf, OpenClaw, and any framework that can run a shell command.
Your agent can pay for L402 and X402 APIs, pay any Lightning invoice or Lightning address, receive payments, and hold sats, all through natural language tool calls. Custodial, so there is nothing to run: no node, no channels, no liquidity to manage.
Quick start (60 seconds)
Claude Code
claude mcp add lightning-wallet -- npx -y lightning-wallet-mcp
Then in Claude: "Register a Lightning wallet for me".
