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

| 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.

| 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.
