MCP server

@marketmayhem/mcp

Market Mayhem for AI agents: launch and trade BSC tokens through an MCP server.

• Your wallet signs, locally. The key never leaves this process. Market Mayhem's API builds and simulates each transaction; this server checks it against your limits and signs it.
• Dry run by default. Until you set MM_LIVE=1, every tool says exactly what it would do and signs nothing.

No install at all? Add https://marketmayhem.co/api/mcp as a connector in Claude, ChatGPT or any MCP client. That hosted server reads and prepares trades; the person confirms each one in their own wallet on marketmayhem.co. This package is for an agent with its own wallet.

Tools

Errors come back as { error, message, fix }, so the agent can correct itself.

Setup

Claude Desktop (claudedesktopconfig.json), Cursor, or any MCP client:

{
  "mcpServers": {
    "marketmayhem": {
      "command": "npx",
      "args": ["-y", "@marketmayhem/mcp"],
      "env": {
        "MM_PRIVATE_KEY": "0x… the agent's own wallet",
        "MM_MAX_PER_TX": "BNB:0.05",
        "MM_MAX_PER_DAY": "BNB:0.25"
      }
    }
  }
}

Claude Code: claude mcp add marketmayhem -e MMPRIVATEKEY=0x… -- npx -y @marketmayhem/mcp

Settings

A sell spends no money, so only the allowlist applies to it. A first-time sale sends the one-time approvals first, then the trade.
