Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to marketmayhem.co, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Market Mayhem MCP lets an AI agent launch and trade BSC tokens with its own wallet, dry run by default and capped by spend limits.

What you can do: Read market settings, contracts, fees and pair currencies, and list new token launches or inspect a single token's pool, fee tier and creator.
Quote buys and sells with price impact and fee, then buy or sell within the configured caps and token allowlist.
Launch a token, optionally with a first buy split across up to 8 wallets and a royalty burn percentage.
Check transaction status as pending, mined or indexed, and view referral earnings or a referral link.
When to use it: For agents that need to trade or launch tokens on BSC autonomously, with a dedicated wallet and hard spend limits. Also useful for read-only monitoring of new launches and quotes when no key is configured.
Requirements: Runs as a remote endpoint or as a local npm package via npx (Node.js). A wallet private key in MM_PRIVATE_KEY is needed to sign; without it the server is read-only, or MM_WALLET gives an address to dry run as. MM_LIVE=1 is required to send transactions. Optional MM_API_KEY, plus MM_MAX_PER_TX, MM_MAX_PER_DAY, MM_ALLOW_TOKENS, MM_API_URL, MM_RPC_URL and MM_STATE_DIR. Network access to the Market Mayhem API and a BSC node.

Before you install

MM_PRIVATE_KEY is a real wallet key that signs transactions; use a dedicated wallet holding only what the agent may spend. Setting MM_LIVE=1 lets the agent spend real funds, so keep MM_MAX_PER_TX and MM_MAX_PER_DAY tight; a currency with no cap cannot be spent. Trades, launches and first-time sale approvals write on-chain and cost fees. MM_API_KEY makes your wallet the default referrer on every trade. Transactions are built and simulated by Market Mayhem's API.

Installation

In SourceWeft

Open Marketmayhem in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/co.marketmayhem%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

@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:

json

{  "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"      }    }  }}

{  "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.
