概要

What is Liveauth Mcp Server?

Liveauth Mcp Server is an MCP server that provides authentication, pay-per-call metering, and signed receipts for AI agents and MCP tools. It uses proof-of-work (free, no account) or Lightning Network micropayments (sats) to gate API access, then meters and monetizes subsequent tool calls with per-call pricing and HMAC-signed receipts. It is designed for API providers and agent builders who want to stop bots, charge per call, and issue a tamper-evident audit trail.

How to use Liveauth Mcp Server?

You can run Liveauth Mcp Server in demo mode (no account) with npx @liveauth-labs/mcp-server. For production, set the LIVEAUTH_API_KEY environment variable and add it to your MCP client configuration (e.g., Claude Desktop’s claude_desktop_config.json). It also provides a TypeScript SDK for programmatic use, with helper functions like createMcpClient and createMcpGate.

Key features of Liveauth Mcp Server

  • Proof-of-work and Lightning Network authentication (no accounts required)
  • Per-call metering with configurable pricing in sats
  • HMAC-SHA256 signed receipts (mcp-call-receipt-v1) for every paid invocation
  • idempotent revenue events with retry-safe keys
  • L402 bundle support for prepaid MCP sessions

Use cases of Liveauth Mcp Server

  • Stop bot scraping at the protocol layer using cost-of-attack economics
  • Allow AI agents to access paid APIs without signup or OAuth
  • Issue a verifiable audit trail for every paid tool call
  • Offer Lightning-backed L402 bundles for prepaid MCP access

よくある質問

1

What is the difference between demo and production mode?

Demo mode returns a real Lightning invoice but simulates payment confirmation, so you can test the flow without an account. Production mode requires a LiveAuth API key and confirms payments against the LiveAuth backend.

2

What authentication methods does it support?

It supports proof-of-work (PoW) challenges, Lightning Network invoices (BOLT11), and L402 bundle macaroons.

3

How do signed receipts work?

Each paid tool invocation returns an HMAC-SHA256 signed receipt with a revenue event ID, sats amounts, and metadata. Receipts can be stored with tool results for later auditing or reconciliation.

4

What are the runtime dependencies?

Liveauth Mcp Server requires Node.js and runs via `npx` or as an installed npm package. It communicates with `api.liveauth.app` over HTTPS and assumes your MCP client supports stdio (JSON‑RPC 2.0).

5

Can it be used with other MCP clients besides Claude Desktop?

Yes, it works with any MCP-compatible client (Cursor, VS Code, ChatGPT, Windsurf, Continue, Cline) that supports stdio transport.
