Printr MCP

Let AI agents print tokens for you

What is Printr MCP?

Printr MCP is a Model Context Protocol server that lets AI agents create, discover, and manage tokens across multiple chains. Think of it as giving Claude, Cursor, or any MCP-compatible AI the power to print tokens on your behalf.

• GitHub: https://github.com/PrintrFi/printr-mcp

• NPM: @printr/mcp

Why use it?

• Zero config - Works out of the box, no API key needed

• Multi-chain - Print tokens on EVM + Solana at once

• Your keys, your control - Private keys never touch the AI

• Browser signing - Sign with MetaMask or Phantom like normal

• Local wallet storage - Encrypted keystore on your machine

Quick Start

Automated Setup (Recommended)

The CLI auto-detects your AI clients and sets everything up:

# Using Bun (recommended)
bunx @printr/mcp setup

# Using Node.js
npx @printr/mcp setup

# Want AI-generated token images? Add your OpenRouter key
bunx @printr/mcp setup --openrouter-api-key <key>

# Target a specific client
bunx @printr/mcp setup --client claude-desktop

One-liner Install

curl -fsSL https://raw.githubusercontent.com/PrintrFi/printr-mcp/main/scripts/install.sh | bash

Manual Setup

Claude Desktop

Config location:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "printr": {
      "command": "npx",
      "args": ["-y", "@printr/mcp@latest"]
    }
  }
}

Claude Code CLI

claude mcp add --scope user printr -- npx -y @printr/mcp@latest

Cursor

Config location: ~/.cursor/mcp.json

{
  "mcpServers": {
    "printr": {
      "command": "npx",
      "args": ["-y", "@printr/mcp@latest"]
    }
  }
}

VS Code

Add to your VS Code settings:

{
  "servers": {
    "printr": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@printr/mcp@latest"]
    }
  }
}

Configuration

Environment Variables

Core

Variable	Description	Default
PRINTR_API_KEY	Partner API key	Public AI-integration key
PRINTR_API_BASE_URL	API endpoint	https://api-preview.printr.money
PRINTR_APP_URL	Web app URL	https://app.printr.money

Variable	Description	Default
OPENROUTER_API_KEY	OpenRouter API key	-
OPENROUTER_IMAGE_MODEL	Image model to use	google/gemini-2.5-flash-image

Autonomous Mode

For full automation without browser prompts:

Variable	Description	Note
EVM_WALLET_PRIVATE_KEY	Hex private key for EVM	Signs without prompts
SVM_WALLET_PRIVATE_KEY	Base58 keypair for Solana	Signs without prompts
AGENT_MODE	Set to 1 for headless mode	Skips all interactive flows
PRINTR_WALLET_STORE	Custom keystore path	Default: ~/.printr/wallets.json

---

Supported Chains

EVM

Base, Ethereum, Polygon, Avalanche, Arbitrum, BNB Chain, Monad, Mantle

Solana

Full support with instruction encoding/decoding.

Signing Options

Three ways to sign transactions:

1. Browser-based (Recommended) - Opens MetaMask or Phantom via printr_open_web_signer. You stay in control.

2. Private key input - Pass keys directly for automation workflows.

3. Encrypted keystore - Password-protected local storage at ~/.printr/wallets.json.

Your private keys never go to the AI. Signing happens locally in your browser or via encrypted storage.

---

Example Flow

Here's how an AI agent might print a token for you:

1. printr_quote
   → Get cost estimates for Base + Solana

2. printr_create_token
   → Generate unsigned transactions

3. printr_open_web_signer
   → You connect MetaMask/Phantom in browser
   → Sign the transactions

4. printr_get_deployments
   → Monitor until status = "live"

5. Done! Trade at:

Full Automation

Want the AI to handle everything without prompts?

export EVM_WALLET_PRIVATE_KEY=0x...
export SVM_WALLET_PRIVATE_KEY=...
export AGENT_MODE=1

# Now printr_launch_token goes brrr without interruption

Security

• Keys stay local - Handled via browser, encrypted keystore, or env vars only

• Session isolation - Bound to 127.0.0.1 with 30-minute TTL

• AES-256 encryption - Stored wallets use AES-256-GCM + scrypt

• Balance checks - Verifies funds before signing
