@printr/mcp
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](https://printrfi.github.io/printr-mcp/)
Setup
Add to your MCP client config (Claude Desktop, Cursor, etc.):
{
"mcpServers": {
"printr": {
"command": "npx",
"args": ["-y", "@printr/mcp@latest"]
}
}
}Or with bunx:
{
"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.
npx skills add PrintrFi/printr-mcpPreview without installing:
npx skills add PrintrFi/printr-mcp --listThe 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.
"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:
"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.

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 + testPackage-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 buildUsing the SDK directly
Uses createPrintrClient and buildToken:
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);
