@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

Configuration

HTTP Mode (Cloud MCP)

Run MCP over HTTP (for cloud hosting or mcp.1ly.store):

# HTTP transport
MCP_TRANSPORT=http npx @1ly/mcp-server

# Custom host/port
MCP_TRANSPORT=http MCP_HTTP_HOST=0.0.0.0 MCP_HTTP_PORT=3000 npx @1ly/mcp-server

Environment Variables

A wallet is required only for paid calls. For free search/details you can run without a wallet. Use one of: ONELY_WALLET_SOLANA_KEY, ONELY_WALLET_EVM_KEY, or ONELY_WALLET_PROVIDER=coinbase.

Claude Desktop Configuration

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "1ly": {
      "command": "npx",
      "args": ["@1ly/mcp-server"],
      "env": {
        "ONELY_WALLET_SOLANA_KEY": "/Users/yourname/.1ly/wallets/solana.json",
        "ONELY_BUDGET_PER_CALL": "1.00",
        "ONELY_BUDGET_DAILY": "50.00"
      }
    }
  }
}

Note: Replace /Users/yourname with your actual home directory. On Linux use /home/yourname. ~ does not work in Claude Desktop config.

{
  "mcpServers": {
    "1ly": {
      "command": "npx",
      "args": ["@1ly/mcp-server"],
      "env": {

        "ONELY_BUDGET_DAILY": "50.00"
      }
    }
  }
}

Cursor One-Click Install

      }
    }
  }
}

{
  "mcpServers": {
    "1ly": {
      "command": "npx",
      "args": ["@1ly/mcp-server"],
      "env": {

Token Tools (Bags.fm)

These tools require a Solana wallet (ONELY_WALLET_SOLANA_KEY)

1ly_launch_token

Launch a token on Bags.fm (v2 flow).

Key fields:

• name, symbol (required)
• description (optional; defaults to Token launched via 1ly.store)
• imageUrl or imageBase64 (required; at least one)
• twitter, website, telegram (optional URLs)
• initialBuySol (optional; defaults to 0)
• feeClaimers (optional array of { provider, username, bps })
• share_fee (optional, bps). Adds a 1ly marketplace fee claimer on the backend. If set, the creator share is auto‑reduced.

Validation (Bags.fm compatible):

• name max 32 chars
• symbol max 10 chars
• description max 1000 chars
• imageBase64 must be raw base64 (no data URL prefix) and <= 15MB decoded

feeClaimers provider list is strict: twitter, github, kick, tiktok. Remainder after feeClaimers (and share_fee, if set) is assigned to the creator wallet.

bps = basis points: 10000 = 100%, 1000 = 10%, 100 = 1%.
Example: 90% to a GitHub claimer + 1% share_fee:

{
  "feeClaimers": [{ "provider": "github", "username": "abc", "bps": 9000 }],
  "share_fee": 100

1ly_list_tokens

List tokens launched by a wallet (public listing by wallet address, default limit 10). If creatorWallet is omitted, the tool uses the configured Solana wallet.

1ly_claim_fees

Claim Bags fee share for a token. If nothing is claimable, the backend returns an error like Nothing to claim.
