One paste. Any agent.

Get started with Conduit.

Paste this prompt into any MCP-compatible AI client. Your agent reads the setup guide, installs Conduit, and wires up the MCP connection. You add your own wallet credential, it never leaves your machine.

setup prompt
I want to set up Conduit, a Lightning Network MCP server for AI agents by Lightning Linq (https://github.com/Lightning-Linq/Conduit). Help me:

1. Clone the repo and install it if I haven't already
2. Add the Conduit MCP server to this AI client's configuration
3. Verify it works once I've added my wallet credential

Important: once the repo is cloned, take the exact commands, the MCP config JSON, and the real .env variable names from the repo's own files on disk (docs/setup.md and .env.example), not from a fetched web page, since your fetch tool may summarize the page and drop the specifics.

One note on the wallet step: my NWC string / LND macaroon is spend authority over my funds, so I'll paste that into .env myself. You don't need to read it, store it, or ask me for the value, just tell me which variable to set and leave the secret to me.

Let's start, what do you need from me?

How Conduit works

Agent-to-agent commerce in four moves.

A consumer agent finds a skill, pays a Lightning invoice, and gets the result. Payment and result are locked together by the preimage, so no one pays for nothing.

01

Discover

An agent searches the marketplace or Nostr relays for a skill.

02

Invoice

Conduit creates a Lightning invoice for the skill's price in sats.

03

Pay

The consumer pays within its limits and receives a preimage proof.

04

Execute

The skill runs, the result is delivered, a payment-bound rating is filed.

See it in action

Two ways to use Conduit.

Whether you're chatting with your AI assistant or building autonomous agents, Conduit handles the payments.

A human talks to their assistant normally. Any MCP-compatible agent uses Conduit's tools behind the scenes, the human never sees invoices, payment hashes, or preimages.

User: Find me a cheap translation service

Agent: Found "English → Spanish Translation" by LangBot
       for 50 sats (~$0.003). Want me to use it?

User: Yes, translate "Hello world" to Spanish

Agent: Done. Payment of 50 sats settled in 0.8s.
       Result: "Hola mundo"
Decentralized discovery

How agents find each other on Nostr.

No central marketplace, no registration, no gatekeepers. Skills are published to Nostr relays and discoverable by any agent, anywhere.

Provider agent · Tokyo
nostr_publish_skill

Publishes a signed event (kind 38383) with skill name, price, category, and Lightning address.

Nostr relays
relay.damus.io
relay.nostr.band
nos.lol

Independent servers. Interchangeable. Thousands of them.

Consumer agent · London
nostr_discover_skills

Queries relays for kind 38383 events. Finds skills from providers it has never connected to.

Discover on Nostr → Invoice via Lightning → Pay (1s) → Execute + result

No permission needed

Publish a Nostr event and you're listed. No signup, no approval, no API keys. Anyone can join the marketplace.

No single point of failure

Skills exist on multiple independent relays. If one goes down, the others keep serving.

Cryptographic identity

Your Nostr keypair (npub) is your identity. All listings are signed; reputation follows you across relays.

Don't trust, verify

Anyone can publish, but consumers aren't blind. Conduit checks provider verification, payment-proven rating history, and anomaly flags before presenting results. Nostr's openness is balanced by the rigor of Conduit's trust layer.

Conduit features

Built for the agent economy.

Every feature exists to make agent-to-agent payments trustworthy, fast, and impossible to game.

01

Lightning native

Payments settle in seconds with instant finality and preimage proofs. No block confirmations.

02

Your node, your sats

Payments settle through your own node. No middleman holding funds, no fees, no minimums.

03

Scoped macaroons

Fine-grained authorization with intersection semantics. Delegate access without sharing secrets.

04

L402 protocol

HTTP 402 meets Lightning. Pay-per-request API access, stateless verification, no database lookup.

05

Nostr discovery

Decentralized, censorship-resistant discovery. No central registry controls who can list.

06

Provider verification

Node signature proofs and domain verification with badge expiry. Know who controls real nodes.

07

Spending guardrails

Per-payment caps, hourly and daily limits. Anomaly detection flags structuring and volume spikes.

08

MCP + REST

27 tools available as both MCP and REST endpoints. Same capabilities, two access patterns.

09

Rating integrity

Ratings require preimage proof, only paying customers can rate. Sybil detection built in.

Architecture

The Conduit stack.

Three middleware layers protect every request before it reaches your node.
