Marketmayhem tools (18, 2 write)

write = sends, deletes, buys or posts
  • cashbackFree

    A wallet's cashback, paid weekly in $MAYHEM: its rate (a share of the site fee it paid; higher for wallets that came through a referral link), this week so far, and weeks ready to claim.

  • get_settingsFree

    The live network (chainId 56 = BSC mainnet, 97 = testnet), contracts, fees and pair currencies.

  • get_tokenFree

    Any BNB Chain token: symbol, name, pool, pool kind, fee tier, pair currency, measured taxes, and whether it launched on Uprally (`ours`). Use quote for a price.

  • intent_statusFree

    Whether a prepared request was signed: open (waiting for the person), sent (with the transaction and whether it is confirmed), or expired (prepare a new one).

  • list_tokensFree

    Tokens launched elsewhere that trade on BNB Chain with a real market ($10K+ liquidity, traded in the last 7 days), deepest first, each with its main pool and its Uprally links. For a token picker or to suggest what to trade; any other token still works by address with get_token and quote.

  • new_launchesFree

    Tokens launched on Uprally, newest first. Pass `after` (the previous answer's `next`) for only what launched since.

  • prepare_buywrite actionFree

    Prepare a buy for the person to sign on uprally.co: a token launched on Uprally, or any token in a PancakeSwap V2 or V3 pool (curve, Infinity and Uniswap tokens: quote works; send them to uprally.co/x/<token>). Returns a link and a summary; nothing is bought until they confirm in their own wallet.

  • prepare_launchFree

    Prepare a token launch for the person to sign on uprally.co. Needs a name, a ticker, an opening market cap and a logo link. Optional first buy in the same transaction (so nobody buys before them), split across up to 8 wallets; the dead address 0x000000000000000000000000000000000000dEaD burns that part. burnPct sends the creator royalty to buy back and burn. Nothing launches until they confirm.

  • prepare_sellFree

    Prepare a sale for the person to sign on uprally.co (the same tokens as prepare_buy; a token not launched on Uprally pays out BNB): `amount` in whole tokens or `percent` of what their wallet holds. Nothing is sold until they confirm.

  • quoteFree

    What a buy or a sale of any BNB Chain token would get right now: amounts, minimum after slippage, taxes, site fee and price impact. Sends nothing.

  • referral_earningsFree

    What a wallet has earned as a referrer (instant and lifetime), its links, and any weeks waiting to be claimed.

  • referral_linkFree

    A referral link for a wallet: people who trade through it pay that wallet a share of the fee, for life. The wallet must be registered or a creator to earn.

  • token_lockFree

    One token lock: owner, cliff, end, withdrawn, balance, claimable now, and its history.

  • token_locksFree

    Token locks by token or by wallet, with live balances. By token it also says how much of the supply is locked: only locks paid for by their own owner and holding at least 0.01% count, because anyone can lock dust or lock for someone else.

  • twap_orderwrite actionFree

    One TWAP order's history: each slice (amounts, fees, transaction), slots skipped and why, cancels and changes.

  • twap_ordersFree

    TWAP orders (a buy or sale spread over time in slices) by wallet or by token, newest first, with progress and whether the keeper has paused one (price past its limit, needs gas).

  • tx_statusFree

    Where a transaction is: pending, failed, confirmed or indexed.

  • what_can_you_doFree

    What this server can and cannot do, and how a trade or launch gets signed. Call this if unsure.

What the publisher says

From the Marketmayhem repository's README, as published. We do not edit it. Read it on GitHub

@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.

Docs: marketmayhem.co/developers · For AIs: marketmayhem.co/llms.txt

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.

Nothing above is checked by us. What we check is on the safety report.
