About ubi

ubi is an umbrella skill for working with ubi.fun, directing users to trading, token-launch, or Circle Agent Wallet skills. It documents the Arc network, fees, and the MCP server’s unsigned-transaction trust model.

Key features

  1. 01Routes tasks to focused ubi.fun skills
  2. 02Documents Arc network and token details
  3. 03Explains fees and creator vaults
  4. 04Describes unsigned transaction handling

Use cases

  1. 01Choose a skill for trading or launching tokens
  2. 02Review network and fee details before use

MCP support

The skill identifies the ubi MCP server at https://api.ubi.fun/mcp and provides connection examples. The server returns unsigned transaction steps and does not handle wallet keys or send transactions.

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/ubidotfun/skills --skill ubi

After installing, type/ubiin Claude Code to confirm it loaded.

Details

From the project README

ubi.fun

Umbrella skill. Pick the deeper skill that matches the job:

  • Trade tokens, quote prices, discover markets, earn the 5% referrer share, collect dividends, creator earnings and rewards, write or read notes, follow another wallet's note → ubi-trading
  • Launch a token (image, metadata, creator vault, one transaction), USDC-paired, or v3 paired with an asset (gold today) → ubi-launch
  • Let the agent send the transactions itself from a Circle Agent Wallet → ubi-circle

Facts that apply everywhere

  • Chain: Arc mainnet, chain id 5042. Gas is USDC. The cash side of every pool is USDC (6 decimals); tokens have 18 decimals and a fixed 100 billion supply. v3 tokens (since October 17, 2026) pair with an asset instead, gold (XAUm) today, and have 1 billion supply; you still trade them in USDC, through their route. Fund the wallet with USDC on Arc first (https://ubi.fun/bridge moves USDC from other chains over Circle CCTP).
  • MCP server: https://api.ubi.fun/mcp (Streamable HTTP, no API key). Connect with:
    • Claude Code: claude mcp add --transport http ubi https://api.ubi.fun/mcp
    • Generic config: { "mcpServers": { "ubi": { "type": "http", "url": "https://api.ubi.fun/mcp" } } }
  • Trust model: the MCP never requests, stores, or uses wallet keys, and never sends transactions. Tools named prepare_* return unsigned { chainId, to, data, value } steps; simulate, sign, and send them with your own wallet tooling.
  • Fees: every token launched since October 4, 2026 has a creator vault and a trading fee of 1.5% to 5%, fixed at launch; older tokens pay 1.25%. A referrer named on a swap takes 5% of its fee first, on every token. On vault tokens the rest settles to 77% creator side (the creator, the token's holders, and its buyback), 13% $UBI holders, 10% protocol. v3 tokens set a buy fee and a sell fee (1.5% to 5% each) and pay in their pair asset.

  • $UBI (0xFA3fFdF775CC3f6ac82Cd258Fb948a8a21e1749e) is the platform token: once a day the holder pool pays USDC to $UBI holders by time-weighted balance, and gold from v3 tokens' fees from the October 18, 2026 round.
