FAQ from pumpfun-mcp

What dependencies does pumpfun-mcp require?

Node.js, npm, a Helius RPC URL (free tier available), and optionally an existing Solana wallet private key.

How are Solana keys managed?

Keypairs are stored as JSON files in the .keys folder. A default account is created if none is provided; you can also convert a private key from .env into a keypair file using node convert-key.js.

Can I use my own Solana wallet?

Yes. Add your base58 private key to the .env file as PRIVATE_KEY, then run node convert-key.js to generate the keypair file.

What is the default slippage tolerance?

The default slippage tolerance is 1% (100 basis points). You can override it per transaction using the slippageBasisPoints parameter.

Are there any image restrictions when creating tokens?

Yes. When providing an image, you must use a local file path; remote URLs are not supported.
