"Lightning" matching MCP servers:

Persistent memory and payment safety for AI agents on Lightning. Enables agents to remember purchases, track vendor reputations, enforce budgets, and share trust signals via Nostr.

MCP server that gates API calls to AI agents using proof-of-work (free) or Lightning payment (3 sats), providing challenge, verify, and status tools for per-call authentication without accounts.

MCP server exposing a Lightning wallet to LLM agents over Nostr Wallet Connect (NIP-47): balance, invoices, LN address/LNURL payments, batch pay, and keysend. All spend tools are wrapped in a defense-in-depth safety stack — budget caps, allowlist, two-step confirmation, audit log.

Enables AI agents to discover, evaluate, and purchase live data from the Macaroon Network marketplace using semantic search, metadata checks, and Bitcoin Lightning payments.

Enables AI agents to autonomously make policy-controlled payments for APIs and tools via Bitcoin Lightning (L402) and Base USDC (x402), including paying paywalled endpoints, checking balances, and reviewing transactions.

Discover and pay for APIs and MCP tools per call over Bitcoin Lightning (L402): search the bolthub marketplace, preview prices, and pay from your own wallet (LND, NWC, LNbits) with hard budgets, prepaid credit, scoped sub-agent delegation, and verifiable receipts. Non-custodial and works without a wallet for search and free tools.

Enables AI agents to browse the giftcardshop catalog and purchase gift cards using Lightning payments, with no account or signup required.

An MCP server that enables AI agents to manage merchant payment processing through the BTCPay Server Greenfield REST API. It supports tools for creating invoices, managing stores, tracking payments, and performing Lightning Network operations.

L402 + x402 client MCP. AI agents discover, pay for, and consume any payment-gated API autonomously. Supports Lightning (NWC), Cashu ecash, stablecoins, and human-in-the-loop payments.

Authentication, pay-per-call metering, and signed receipts for AI agents and MCP tools using Bitcoin and Lightning Network.

Pay-per-use semantic web search for AI agents. Powered by SearxNG, agents pay in sats via Lightning Network micropayments — no API keys required.

Enables AI assistants to interact with the Blink Bitcoin and Lightning Network API for managing wallets, payments, invoices, and L402 services.

Generic Lightning-paywall sidecar that wraps any stdio MCP server and requires a paid Lightning invoice (via NWC) before forwarding priced tool calls. Per-tool prices are set via env; includes payment verification, replay protection, and an audit log — the upstream server stays untouched.

An MCP server that enables AI agents to accept Bitcoin Lightning payments. It allows agents to create orders, generate invoices, check payment status, and manage the full SatsRail merchant API through natural language.

Exposes Charles Schwab brokerage data to AI assistants via MCP, enabling natural language queries about positions, option chains, account balances, and trade audits with Lightning micropayment monetization.

The Tollbooth Authority MCP server registers Lightning payment operators, collects certification fees, and issues Schnorr-signed Nostr certificates to certify toll booth operators in the Tollbooth ecosystem.

Provides a 1-line USDC paywall wrapper for any FastMCP tool using the Coinbase x402 protocol, enabling pay-per-call endpoints settled on Base, Polygon, Solana, or Bitcoin Lightning.

Enables AI agents to manage Bitcoin micropayments, service offers, and escrow contracts through MCP tools, without requiring a Lightning node.

Enables operators to run a monetized multiplayer hive-race game, using Tollbooth DPYC Bitcoin Lightning micropayments for paid tools, pricing, credential intake, board management, match coordination, and settlement tracking.

MCP server for the DPYC ecosystem that certifies North American operators using the Lightning network, enabling regional certification and audit trails with low latency.
