Agent Launch Protocol
Tell your AI agent what you want to launch.4.fun prepares everything. You review and sign.
Launch, discover and integrate 4.fun markets from Claude Code, Cursor and any MCP-compatible agent — without giving the agent your keys.
Natural language drafts
Describe a token. 4.fun builds an unsigned launch draft from the same Factory path the website uses.
Wallet-safe by design
No server wallets. No autonomous signing. Every launch or trade ends in your wallet confirmation.
MCP + public API
Install once in Claude Code or Cursor. Discover tokens, quote trades, and open a review handoff URL.
One-command install
Package status: Public npm package (@fourdottfun/mcp). Recommended API base: https://api.4.fun.
