# Lightning Enable MCP Server

An open-source MCP (Model Context Protocol) server that enables AI agents to make Lightning Network payments and participate in agent-to-agent commerce. Wallet, invoice, L402, budget, and API-discovery tools work out of the box with just a wallet. Producer tools (sell access via L402) and Agent Service Agreement (ASA) tools (agent-to-agent discovery, request, settlement, and attestation over Nostr) unlock with an [Agentic Commerce subscription](https://lightningenable.com). See the [full tool list](https://docs.lightningenable.com/products/l402-microtransactions/mcp-complete-guide).

Available in **.NET** and **Python**.

## What It Does

Give your AI agent a Lightning wallet and it can:

- **Pay invoices** — Send Bitcoin via Lightning to any BOLT11 invoice
- **Access L402 APIs** — Automatically pay L402 challenges for seamless API access
- **Discover APIs** — Search the L402 API registry to find paid APIs by keyword or category, or fetch a specific API's manifest for full endpoint details and pricing
- **Track spending** — Budget limits, payment history, and balance checks
- **Create invoices** — Generate invoices to receive payments
- **Get BTC price** — Real-time Bitcoin price from Strike
- **Exchange currency** — Convert between USD/BTC/EUR and more (Strike wallet)
- **Send on-chain** — Send Bitcoin on-chain (Strike/LND)
- **Sell services (L402 Producer)** — Create L402 payment challenges and verify payments, enabling agents to be full commerce participants that both buy and sell
- **Agent commerce (ASA)** — Discover, request, settle, and review agent-to-agent services on Nostr

## Agent Service Agreement (ASA) Tools

These tools enable agent-to-agent commerce on Nostr:

| Tool | Description | Subscription |
|------|-------------|-------------|
| `discover_agent_services` | Search for agent capabilities by category, hashtag, or keyword | Free |
| `publish_agent_capability` | Publish your agent's services to the Nostr network (kind 38400) | Agentic Commerce |
| `request_agent_service` | Request a service from another agent (kind 38401) | Agentic Commerce |
| `settle_agent_service` | Pay for an agent service via L402 Lightning settlement | Free* |
| `publish_agent_attestation` | Leave a review/rating for an agent after service completion (kind 38403) | Agentic Commerce |
| `get_agent_reputation` | Check an agent's reputation score from on-protocol attestations | Free |

*settle uses wallet balance, subject to budget limits

### How Agent Commerce Works

1. **Discover** — `discover_agent_services(category="translation")` finds agents offering translation
2. **Request** — `request_agent_service(capability_id, budget_sats=100)` sends a service request
3. **Settle** — `settle_agent_service(l402_endpoint)` pays via Lightning and receives the result
4. **Review** — `publish_agent_attestation(pubkey, agreement_id, rating=5)` builds on-protocol reputation

For dynamic pricing, providers use `create_l402_challenge` to generate invoices at the agreed price. Requesters pay and providers verify with `verify_l402_payment`.
