Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
prepare
prepare_buy
Prepare a buy for the person to sign on uprally.co: a token launched on Uprally, or any token in a V2 or V3 pool (any other token, such as one on a launchpad curve: 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_launch
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_sell
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 ETH): `amount` in whole tokens or `percent` of what their wallet holds. Nothing is sold until they confirm.
token
get_token
Any Robinhood 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.
token_lock
One token lock: owner, cliff, end, withdrawn, balance, claimable now, and its history.
token_locks
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.
referral
referral_earnings
What a wallet has earned as a referrer (instant and lifetime), its links, and any weeks waiting to be claimed.
referral_link
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.
twap
twap_order
One TWAP order's history: each slice (amounts, fees, transaction), slots skipped and why, cancels and changes.
twap_orders
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).
intent
intent_status
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).
new
new_launches
Tokens launched on Uprally, newest first. Pass `after` (the previous answer's `next`) for only what launched since.
quote
quote
What a buy or a sale of any Robinhood Chain token would get right now: amounts, minimum after slippage, taxes, site fee and price impact. Sends nothing.
settings
get_settings
The live network (chainId 4663, Robinhood Chain), contracts, fees and pair currencies.
status
tx_status
Where a transaction is: pending, failed, confirmed or indexed.
tokens
list_tokens
Tokens launched elsewhere that trade on Robinhood 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.
what
what_can_you_do
What this server can and cannot do, and how a trade or launch gets signed. Call this if unsure.

Marketmayhem — questions
Answers built from our own checks of this server.
What can Marketmayhem do?
It exposes 17 tools, read directly from the server on our last check. Among them: get_settings, get_token, intent_status, list_tokens, new_launches, prepare_buy and 11 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is Marketmayhem mostly used for?
Its tools cluster around token, prepare and referral. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Marketmayhem working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 207 ms. The bar chart above shows every period we have measured.
Did Marketmayhem ever remove tools?
Yes. cashback is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
The registry lists Marketmayhem as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Marketmayhem?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Marketmayhem need an API key?
No. Marketmayhem completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 17 of them are readable on this page. This is what we observed, not what the docs claim.
How many people use Marketmayhem?
The npm package @marketmayhem/mcp was installed 129 times in the last week. Week over week that is -12%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Marketmayhem open source?
The code is open source: it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at marketmayhem.co, which runs on its operator's own terms.
