@printr/mcp

MCP server for Printr — lets AI agents create, discover, and track tokens across chains.

No API key required. Works out of the box.

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"]
        }
    }
}

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.
