@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

Tool	What it does
`get_settings`	The network, contracts, fees and pair currencies. Read first.
`new_launches`	Tokens launched, newest first. Pass `after` to get only new ones.
`get_token`	One token: pool, fee tier, pair currency, creator.
`quote`	What a buy or sell would get now, with price impact and fee.
`buy` / `sell`	Trade, within your caps and allowlist. `sell` takes `amount` or `percent`.
`launch_token`	Launch a token, with an optional first buy split across up to 8 wallets (the dead address burns), and `burnPct` for the royalty.
`tx_status`	Pending, mined or indexed.
`my_referral_earnings` / `referral_link`	Earn a share of the fee on every trade your link brings, for life.

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

Setup

Claude Desktop (claude_desktop_config.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 MM_PRIVATE_KEY=0x… -- npx -y @marketmayhem/mcp

Settings

Variable	Default	Meaning
`MM_LIVE`	unset (dry run)	`1` lets the agent send.
`MM_PRIVATE_KEY`	—	The agent's own wallet. Use a wallet made for it, holding only what it may spend.
`MM_WALLET`	—	Without a key: an address to dry run as. It can never send.
`MM_MAX_PER_TX`	`BNB:0.05`	The most one transaction may spend, per currency (`BNB:0.05,USDT:50`).
`MM_MAX_PER_DAY`	`BNB:0.25`	The most per UTC day, per currency. A currency with no cap cannot be spent.
`MM_ALLOW_TOKENS`	any	Comma-separated tokens the agent may buy or sell.
`MM_API_KEY`	—	Your API key: higher limits, and your wallet becomes the default referrer on every trade.
`MM_API_URL`	`https://marketmayhem.co/api/v1`	The API.
`MM_RPC_URL`	a public BSC node	The node transactions are sent through.
`MM_STATE_DIR`	`~/.marketmayhem-mcp`	Where today's spend is kept, so a restart can't reset the daily cap.

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.
