Printr MCP [NEW]

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

• Developer reference: full MCP tool reference — every tool, its inputs, and outputs

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 (Demo Video)

Automated Setup (Recommended)

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

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

# Using Node.js
npx @printr/cli setup

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

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

One-liner Install

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

Agent Skills

If your agent runtime supports skills, install Printr directly:

npx skills add PrintrFi/printr-mcp

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:
   → https://app.printr.money/trade/{token_id}

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

---

Using the SDK Directly

For programmatic access without MCP, install the SDK:

npm install @printr/sdk
# or
bun add @printr/sdk

Quick Example

import { createPrintrClient, buildToken } from '@printr/sdk';

const client = createPrintrClient({
  apiKey: process.env.PRINTR_API_KEY,
});

const result = await buildToken({
  creator_accounts: ['eip155:8453:0x...'],
  name: 'My Token',
  symbol: 'TKN',
  description: 'A cool token',
  chains: ['eip155:8453'],
  initial_buy: { spend_usd: 10 },
}, client);

if (result.isOk()) {
  console.log('Token created:', result.value.token_id);
}
