Let AI agents create, discover, and track tokens across chains via Printr.

MCP Server: io.github.PrintrFi/printr

This MCP server (@printr/mcp) provides an interface for AI agents to create, discover, and track tokens across chains via Printr. It is associated with the npm package @printr/mcp and the Printr project, and is categorized under agent, ai, ai-agent, and mcp topics.

🛠️ Key Features

Create tokens via Printr for AI agents
Discover tokens across chains
Track tokens across chains

🚀 Use Cases

Enable AI agents to manage token workflows across multiple chains
Support discovery and monitoring of tokens in a cross-chain context

⚡ Developer Benefits

MCP integration with agent-based tooling (agent, ai, ai-agent)
Package availability under @printr/mcp
Maintained repository with CI and code coverage badges

⚠️ Limitations

Available metadata does not list specific MCP tools or interfaces (toolCount not provided)

MCP server for Printr — the cross-chain token launchpad built for holders. Lets AI agents launch, stake, and graduate tokens across EVM chains and Solana.

No API key required. Works out of the box.

📖 Documentation

Setup

Add to your MCP client config (Claude Desktop, Cursor, etc.):

json

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

Or with bunx:

json

{
    "mcpServers": {
        "printr": {
            "command": "bunx",
            "args": ["@printr/mcp@latest"]
        }
    }
}

Skill (optional, complements the MCP config above)

In addition to the MCP config, install the Printr skill to give your agent built-in guidance on when and how to use these tools. Compatible with Claude Code, Cursor, Codex, OpenCode, and 50+ other runtimes.

Preview without installing:

npx skills add PrintrFi/printr-mcp --list

The skill is auto-discovered from packages/cli/skills/printr/SKILL.md. See the skill definition for the full tool list and behavioral hints.

Optional capabilities

Auto-generate token images

Set OPENROUTER_API_KEY and the agent will generate an image automatically when you create a token without supplying one. The printr_generate_image tool also becomes available for standalone image generation.

json

"env": {
    "OPENROUTER_API_KEY": "<your-openrouter-key>"
}

Let the agent sign transactions autonomously

By default, token creation returns an unsigned transaction that you sign via browser wallet or by passing a private key per call. If you want the agent to sign and submit without prompting, set a default key:

json

"env": {
    "EVM_WALLET_PRIVATE_KEY": "<hex-private-key>",
    "SVM_WALLET_PRIVATE_KEY": "<base58-keypair-secret>"
}

Keep private keys out of shared configs. Use environment-level secrets when possible.

Tools

Tool	Description
`printr_quote`	Get cost estimates for token creation
`printr_create_token`	Generate an unsigned token creation tx payload
`printr_launch_token`	Create and sign a token in one call
`printr_get_token`	Look up token details by ID or address
`printr_get_deployments`	Check deployment status across target chains
`printr_sign_and_submit_evm`	Sign and submit an EVM tx payload
`printr_sign_and_submit_svm`	Sign and submit a Solana tx payload
`printr_open_web_signer`	Start a browser signing session (MetaMask / Phantom)
`printr_generate_image`	Generate a token avatar via OpenRouter (requires `OPENROUTER_API_KEY`)

For the full tool list including wallet, balance, transfer, fees, and staking tools, see packages/cli/skills/printr/SKILL.md.

Environment variables

Variable	Description
`PRINTR_API_KEY`	Partner API key. Falls back to the default public AI-integration key.
`OPENROUTER_API_KEY`	Enables auto image generation and the `printr_generate_image` tool
`OPENROUTER_IMAGE_MODEL`	Image model override (default: `google/gemini-2.5-flash-image`)
`EVM_WALLET_PRIVATE_KEY`	Default EVM private key for autonomous signing
`SVM_WALLET_PRIVATE_KEY`	Default Solana keypair secret for autonomous signing
`PRINTR_DEPLOYMENT_PASSWORD`	Master password for encrypting deployment wallets (min 16 chars). Required for `printr_fund_deployment_wallet`. Generate with: `openssl rand -base64 32`

Dev / self-hosting

Variable	Description
`PRINTR_API_BASE_URL`	Override API base URL (default: `https://api-preview.printr.money`)
`PRINTR_APP_URL`	Override app URL (default: `https://app.printr.money`)

Development

This is a monorepo with three packages:

@printr/sdk — Core TypeScript SDK (framework-agnostic)
@printr/mcp — MCP server wrapping the SDK
@printr/cli — CLI for setup and configuration

bun install
bun dev          # Run MCP server with hot reload
bun test         # Run all tests
bun run check    # typecheck + lint + test

Package-specific commands

# SDK
bun run --cwd packages/sdk test
bun run --cwd packages/sdk build

# MCP
bun run --cwd packages/mcp test
bun run --cwd packages/mcp build

Using the SDK directly

Uses createPrintrClient and buildToken:

typescript

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);
