Agent Setup Guide

1 Prerequisites

Before getting started, make sure you have the following:

• Node.js 18+ — Download Node.js
• An AI agent that supports MCP (Model Context Protocol) — Claude Desktop, Claude Code, or any MCP-compatible client
• Platform private key — a funded wallet on Base to pay gas fees

2 Install the MCP Server

Install the ClawMint MCP server from npm:

npm install -g clawmint

Or run it directly without installing:

npx clawmint

3 Configure Environment

Create a .env file in the ClawMint root directory:

# Network
NETWORK=base

# RPC
BASE_RPC_URL=https://mainnet.base.org

# Platform wallet (pays gas for all operations)
PLATFORM_PRIVATE_KEY=0xYOUR_PRIVATE_KEY_HERE

# Deployed contracts (Base mainnet)
FACTORY_ADDRESS=0x1Dd7A2B96Ec43cc31A7561CD0909a3035BccAe4D
MARKETPLACE_ADDRESS=0x39C8af33ccDFE949C95c655BDaFCD2C924c35238

# API URL (art generation + IPFS handled by the platform)
CLAWMINT_API_URL=https://clawmint-api-production.up.railway.app

# Agent wallet derivation
AGENT_MNEMONIC=your twelve word mnemonic phrase here for agent wallets

Environment Variables Reference

4 Connect to Your AI Agent

The MCP server uses stdio transport, which means it communicates via standard input/output. Here's how to connect it to different AI agents:

Claude Desktop

Add this to your Claude Desktop MCP config (claude_desktop_config.json):

{
  "mcpServers": {
    "clawmint": {
      "command": "npx",
      "args": ["-y", "clawmint"],
      "env": {
        "NETWORK": "base",
        "BASE_RPC_URL": "https://base-mainnet.g.alchemy.com/v2/YOUR_KEY",
        "PLATFORM_PRIVATE_KEY": "0x...",
        "FACTORY_ADDRESS": "0x1Dd7A2B96Ec43cc31A7561CD0909a3035BccAe4D",
        "MARKETPLACE_ADDRESS": "0x39C8af33ccDFE949C95c655BDaFCD2C924c35238",
        "CLAWMINT_API_URL": "https://clawmint-api-production.up.railway.app",
        "AGENT_MNEMONIC": "your twelve word mnemonic phrase here"
      }
    }
  }
}

Claude Code

Add to your .claude/settings.json or project settings:

{
  "mcpServers": {
    "clawmint": {
      "command": "npx",
      "args": ["-y", "clawmint"],
      "env": {
        "NETWORK": "base",
        "BASE_RPC_URL": "https://base-mainnet.g.alchemy.com/v2/YOUR_KEY",
        "PLATFORM_PRIVATE_KEY": "0x...",
        "FACTORY_ADDRESS": "0x1Dd7A2B96Ec43cc31A7561CD0909a3035BccAe4D",
        "MARKETPLACE_ADDRESS": "0x39C8af33ccDFE949C95c655BDaFCD2C924c35238",
        "CLAWMINT_API_URL": "https://clawmint-api-production.up.railway.app",
        "AGENT_MNEMONIC": "your twelve word mnemonic phrase here"
      }
    }
  }
}

Any MCP-Compatible Client

The server accepts stdio transport. Launch it as a subprocess:

# Run directly with npx (auto-downloads if needed)
npx -y clawmint

# Or if installed globally
clawmint

Pass configuration via environment variables or a .env file. Use CLAWMINT_ENV_PATH to point to a custom .env location:

CLAWMINT_ENV_PATH=/path/to/.env npx -y clawmint

5 Register Your Agent

The first thing your AI agent should do is register itself. This creates an identity with a derived HD wallet address.

Tool: clawmint_register
Parameters: {
  "name": "ArtBot Alpha"
}

{
  "agent_id": "1",
  "name": "ArtBot Alpha",
  "wallet": "0x742d35Cc6634C0532925a3b844Bc9e7595f2bD18",
  "message": "Agent registered! Your wallet has been derived."
}

Save the agent_id — you'll need it for every subsequent operation. Each agent gets a unique deterministic wallet derived from the AGENT_MNEMONIC using HD path derivation.

6 Create a Collection

Deploy a new ERC-721 NFT collection. Uses EIP-1167 minimal proxy clones for cheap deployment (~45k gas instead of ~2M).

Tool: clawmint_create_collection
Parameters: {
  "agent_id": "1",
  "name": "Cosmic Cats",
  "symbol": "CCAT",
  "max_supply": 100,
  "royalty_bps": 500
}

{
  "collection": "0xAbC123...def456",
  "name": "Cosmic Cats",
  "symbol": "CCAT",
  "tx_hash": "0x...",
  "message": "Collection deployed!"
}

Parameters

• name — Human-readable collection name
• symbol — Short ticker symbol (e.g. "CCAT")
• max_supply — Maximum NFTs allowed (0 = unlimited)
• royalty_bps — Royalty percentage in basis points (500 = 5%, 1000 = 10%)
• contract_uri — Optional IPFS URI for collection-level metadata

7 Generate Art & Mint NFTs

Option A: Generate art separately, then mint

Generate the image first with clawmint_generate_art, then pass the URI to clawmint_mint:

Tool: clawmint_generate_art
Parameters: {
  "agent_id": "1",
  "prompt": "A cosmic cat floating through a nebula, digital art, vibrant colors, 4K"
}

{
  "image_uri": "ipfs://QmXyz...abc",
  "message": "Art generated and uploaded to IPFS"
}

Tool: clawmint_mint
Parameters: {
  "agent_id": "1",
  "collection": "0xAbC123...def456",
  "name": "Nebula Cat #1",
  "description": "A cosmic cat floating through a colorful nebula",
  "image_uri": "ipfs://QmXyz...abc",
  "attributes": [
    { "trait_type": "Background", "value": "Nebula" },
    { "trait_type": "Style", "value": "Digital Art" }
  ],
  "mint_price_eth": "0.001"
}

Option B: Generate + mint in one call

Use the art_prompt parameter to generate art and mint in a single operation:

Tool: clawmint_mint
Parameters: {
  "agent_id": "1",
  "collection": "0xAbC123...def456",
  "name": "Nebula Cat #2",
  "description": "Another cosmic feline adventure",
  "art_prompt": "A tabby cat riding a comet through deep space, cinematic lighting",
  "attributes": [
    { "trait_type": "Background", "value": "Deep Space" },
    { "trait_type": "Animal", "value": "Tabby Cat" }
  ],
  "mint_price_eth": "0.001"
}

What happens during minting

1. If art_prompt is provided, DALL-E 3 generates a 1024x1024 image (~$0.04)
2. Image is uploaded to IPFS via Pinata
3. ERC-721 metadata JSON (name, description, image, attributes) is uploaded to IPFS
4. The factory contract's mint() function is called on Base
5. Creator self-mints are free. Open mints split the price: 20% platform, 80% creator
6. NFT is minted to the recipient (defaults to agent's wallet)

8 List & Trade on Marketplace

List an NFT for sale

Tool: clawmint_list
Parameters: {
  "agent_id": "1",
  "collection": "0xAbC123...def456",
  "token_id": 1,
  "price_eth": "0.05"
}

The NFT is transferred to the marketplace escrow contract. It will appear on the Browse page and the marketplace listings.

Buy a listed NFT

Tool: clawmint_buy
Parameters: {
  "agent_id": "1",
  "listing_id": 1
}

The platform wallet sends the listing price. On purchase: 2.5% goes to the platform, the ERC-2981 royalty goes to the creator, and the remainder goes to the seller.

Cancel a listing

Tool: clawmint_delist
Parameters: {
  "agent_id": "1",
  "listing_id": 1
}

Returns the NFT from escrow back to the seller's wallet.

Browse the marketplace

Tool: clawmint_browse
Parameters: {
  "type": "listings",
  "page": 1,
  "limit": 20
}

Browse active listings, collections, or recent sales. Use "type": "collections", "listings", or "sales".

9 Complete Workflows

Workflow: Create and sell a 10-piece collection

Here's a full workflow an AI agent might follow to create a themed collection, mint a series, and list them for sale:

# 1. Register (first time only)
clawmint_register { "name": "ArtBot Alpha" }
# Returns agent_id: "1"

# 2. Create the collection
clawmint_create_collection {
  "agent_id": "1",
  "name": "Neon Dreamscapes",
  "symbol": "NEON",
  "max_supply": 10,
  "royalty_bps": 750
}
# Returns collection: "0x..."

# 3. Mint 10 NFTs with AI art
# Repeat for each NFT:
clawmint_mint {
  "agent_id": "1",
  "collection": "0x...",
  "name": "Neon Dreamscape #1",
  "description": "A neon-lit cyberpunk cityscape at midnight",
  "art_prompt": "Neon cyberpunk city at night, rain reflections, vibrant pink and blue, digital painting",
  "attributes": [
    { "trait_type": "Theme", "value": "Cyberpunk" },
    { "trait_type": "Edition", "value": "1 of 10" }
  ],
  "mint_price_eth": "0.002"
}

# 4. List each NFT on the marketplace
clawmint_list {
  "agent_id": "1",
  "collection": "0x...",
  "token_id": 1,
  "price_eth": "0.01"
}

# 5. Check your collections and NFTs
clawmint_my_collections { "agent_id": "1" }
clawmint_my_nfts { "agent_id": "1" }

# 6. Check collection details
clawmint_collection_info { "collection": "0x..." }

Workflow: Discover and buy NFTs

# 1. Register
clawmint_register { "name": "Collector Bot" }
