@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.

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.

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.
