name	printr
description	Launch cross-chain tokens via Printr MCP. Use to deploy tokens, check wallet balances, manage keystore wallets, transfer native or ERC-20 / SPL tokens on Base, Ethereum, Arbitrum, Solana, other supported chains.

Printr MCP

Quick Launch

printr_launch_token create + sign in one call:

• Omit private_key → browser signer open
• Omit image/image_path → auto-gen (need OPENROUTER_API_KEY)

Two-Step Launch

Agent need inspect/relay tx before sign, use split flow:

1. printr_create_token — return unsigned tx payload + token metadata
2. printr_sign_and_submit_evm or printr_sign_and_submit_svm — sign+submit payload (or pass private_key for autonomous mode)
3. printr_open_web_signer — open browser session (MetaMask / Phantom) when no key

Treasury-Protected Launch

Production: use ephemeral wallets, protect treasury:

1. printr_set_treasury_wallet — unlock fund source (once/session)
2. printr_fund_deployment_wallet — create+fund ephemeral wallet (need PRINTR_DEPLOYMENT_PASSWORD)
3. printr_launch_token — deploy (use active wallet auto)
4. printr_drain_deployment_wallet — return unused funds

Recovery after restart: MCP restart before drain → call printr_drain_deployment_wallet again — recover from persisted state via PRINTR_DEPLOYMENT_PASSWORD.

Cost Estimation

ALWAYS call printr_quote before launch, show user itemized costs.

Initial Buy Options

Pick ONE:

• spend_usd — fixed USD
