@1ly/mcp-server

MCP server for 1ly.store — Enable AI agents to discover, pay for, and sell APIs using crypto.

Overview

This MCP server gives AI agents the ability to:

• Buy — Search, discover, and pay for APIs/resources with automatic crypto payments (x402 protocol)
• Sell — Create a store, list paid API endpoints or resources, and accept payments
• Launch Tokens — Create and trade tokens on Bags.fm, and claim fee shares

Supported Networks: Solana (mainnet), Base (mainnet) Payment Currency: USDC and $1LY (Solana only)

What is this?

This MCP server enables AI agents (Claude, GPT, Cursor, and more) to:

• Create a store on 1ly.store
• Accept payments for your APIs/resources using 1ly as the payment layer
• Create paid links that any x402‑compatible agent can call and pay automatically
• List paid links on the 1ly marketplace for instant agent discovery
• Search for APIs and services on 1ly.store
• Get details about pricing, reviews, and usage
• Call paid APIs with automatic crypto payments (x402 protocol) securely
• Leave reviews after purchases (optional but recommended)
• Launch tokens on Bags.fm, trade solana tokens, and claim fees

Quick Start

Wallet path rule: wallet files must be located in your home directory (recommended) or /tmp. Paths outside those locations are rejected for security. ~/ is supported and expands to your home directory when running directly from the terminal. Important: Claude Desktop and Cursor config JSON do not expand ~. Always use absolute paths in JSON config files (e.g. /Users/yourname/.1ly/wallets/solana.json).

1. Install and Run

Option A: Raw Wallet (default)

# Solana wallet
ONELY_WALLET_SOLANA_KEY="~/.1ly/wallets/solana.json" npx @1ly/mcp-server

# OR Base/EVM wallet
ONELY_WALLET_EVM_KEY="~/.1ly/wallets/evm.key" npx @1ly/mcp-server

# OR both wallets
ONELY_WALLET_SOLANA_KEY="~/.1ly/wallets/solana.json" \
ONELY_WALLET_EVM_KEY="~/.1ly/wallets/evm.key" \
npx @1ly/mcp-server

Option B: Coinbase Agentic Wallet (Base only)

ONELY_WALLET_PROVIDER="coinbase" npx @1ly/mcp-server

When using Agentic Wallet, you do not pass raw private keys.
Make sure the Coinbase Agentic Wallet app is running and authenticated.

If you haven't installed Agentic Wallet yet:

• Follow Coinbase Agentic Wallet docs: docs.cdp.coinbase.com/agentic-wallet/welcome
• Quick install:

npx skills add coinbase/agentic-wallet-skills
npx awal show

Option C: DCP Local (recommended for secure signing)

# Start DCP locally
dcp init
npx @dcprotocol/server

# Run MCP (auto-detects DCP at localhost:8420)
npx @1ly/mcp-server

Option D: DCP Remote (relay)

# Pairing outputs these values
DCP_VAULT_ID="vault_..." \
DCP_RELAY_URL="wss://relay.dcp.1ly.store" \
DCP_VAULT_HPKE_PUBLIC_KEY="base64..." \
npx @1ly/mcp-server

2. Verify Setup

ONELY_WALLET_SOLANA_KEY="~/.1ly/wallets/solana.json" npx @1ly/mcp-server --self-test

Seller Tools (Accept Payments)

These tools require an API key. There are two ways to get one:

Option A — Via MCP tool (agent does it for you): Run 1ly_create_store and the key is automatically saved locally.

Option B — Via UI (no wallet needed):

1. Go to 1ly.store and sign in
2. Open Settings → enable Developer Mode
3. Create an API key from the dashboard
4. Set it as ONELY_API_KEY in your MCP config

1ly_create_store

Create a new store and get an API key. Run this once. The API key is automatically saved locally.

Note: Creating a store requires a raw wallet key (Solana or EVM). Agentic Wallet does not support store creation yet.

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | username | string
