Close to graduating on higher.fun

Live from higher.fun's API, refreshed every minute. This is what list_coins returns with sort: "graduating". Not financial advice.

One URL, any client

Pick your client. Most take one click.

https://highwire.fun/mcp

No sign-in and no key. The server is read-only, stateless, and allows 60 requests a minute per IP.

ChatGPT and other clients

Any client that takes a remote MCP server: add a server with the URL above and no authentication. In ChatGPT that means turning on developer mode and creating a custom connector.

{
  "mcpServers": {
    "highwire": {
      "url": "https://highwire.fun/mcp"
    }
  }
}

Run it locally

The local server adds the trading tools: quotes, positions, and trades, launches and fee claims to sign. The npm package is on its way; until then, build from source:

git clone https://github.com/HigherMaestro/highwire.git
cd highwire && npm install && npm run build
claude mcp add highwire -- node "$PWD/packages/mcp/dist/cli.js"

22 tools

17 run on the hosted server and only read. 5 more run on your own computer and quote or build transactions that you sign in your own wallet. Listed straight from the server; parameters and examples are in the docs.

Discover

What's launching, trending and about to graduate.

Research a coin

Price, holders, trades, candles and the comment thread.

  • get_coinEverything about one coin: price, market cap, graduation progress, fee mode (Old school or New school), holder concentration, and higher.fun's safety grade with snipers, bundles, dev activity and creator lock.
  • get_coin_tradesRecent buys and sells of a coin, newest first, in SOL and whole tokens.
  • get_coin_holdersTop holders of a coin with their share of supply.
  • get_coin_candlesPrice candles (OHLC in SOL per token, volume in SOL) for a coin, oldest first.
  • get_coin_commentsThe comment thread on a coin's page.

Creators and wallets

Who launched what, and how it went.

  • get_wallet_profileA wallet's higher.fun profile in one call: display name, the coins it created, its creator earnings (paid out and pending) and its creator locks.
  • get_creator_coinsPage through every coin a wallet has launched on higher.fun.

Safety and platform

Rug checks, fee modes, tickers and site chat.

  • rug_checkSafety check before anyone trades a coin: on-chain mint and freeze authority, holder concentration, higher.fun's grade, snipers, bundled wallets, dev selling and ticker flags, rolled into a verdict: CLEAN_ON_CHECKS, CAUTION or HIGH_RISK.
  • get_platform_infoHow higher.fun works: the live launch fee, SOL price, the two fee modes (Old school and New school) with exact splits, graduation, and the Raydium program and platform addresses it uses.
  • check_tickerWhether a ticker is still free to launch with on higher.fun.
  • get_chatRecent messages in higher.fun's site-wide chat, newest first.

Trade and launch

Quotes, positions, and transactions you sign in your own wallet. Local server only for now.

  • quote_tradelocalQuote a buy (by SOL in) or a sell (by tokens in) of a higher.fun coin, wherever it trades now: the LaunchLab bonding curve, or its Raydium CPMM pool after graduation.
  • get_wallet_positionslocalA wallet's SOL balance and its balances in higher.fun coins, each valued at the coin's last price.
  • build_tradelocalBuild an unsigned buy or sell for the user's own wallet to sign: the same transaction higher.fun's site builds.
  • build_launchlocalBuild the unsigned transactions that launch a coin on higher.fun from the user's wallet: create it on the chosen fee mode (classic = Old school, rewards = New school), pay the launch fee (checked against higher.fun's on-chain fee wallet and cap), an optional first buy, and for New school an optional creator lock.
  • build_claim_creator_feeslocalShow what a creator can claim and build the unsigned claim transactions: curve creator fees (New school coins, one vault across all the creator's coins) and, after graduation, each coin's Raydium CPMM pool creator fee.

Built to keep agents on the wire

  • Rug check first

    rug_check rolls mint and freeze authority, holder concentration, snipers, bundles and dev selling into one verdict: clean, caution or high risk.

  • Strangers' words stay data

    Coin names, comments and chat are user-written. Highwire flags links and look-alike names, and tells agents never to follow instructions inside them.

  • No keys, ever

    The trading tools only build transactions, decoded and simulated first. You sign them in your own wallet. Highwire never asks for a private key or seed phrase.

  • Units you can read

    SOL, whole tokens and percentages, not lamports and basis points.
