yoinkai-mcp

YOINK for AI agents, on Robinhood Chain.

Your agent can:

• watch new token launches the moment they land
• check any token before you buy
• quote live prices
• launch a token in one command
• prepare buys and sells
• claim your Genesis key

It never signs and never sends. Every trade and launch comes back as an unsigned transaction. You review it and sign in your own wallet.

Install

Claude Code:

claude mcp add yoink -- npx -y yoinkai-mcp

Cursor, Claude Desktop, or any MCP client:

{ "mcpServers": { "yoink": { "command": "npx", "args": ["-y", "yoinkai-mcp"] } } }

Tools

top_launches The newest token launches on Robinhood Chain: name, symbol, address, deployer, source.

scan_launch Trust Score for any token address: is it sellable, is there a transfer tax, does an owner control it, is the LP locked, does the bytecode match the verified standard template.

deployer_history Every launch from a wallet that the graph has indexed, with a serial-deployer flag. A short history is not proof of a clean one: a venue we do not index yet will not show up here.

graph_stats Totals for the launch graph: tokens indexed, unique deployers, top serial deployers.

quote_token Current price and expected receive amount for any token, routed to its live venue. A token still bonding quotes from its bonding curve contract, with the 1% fee included. A graduated or pool token quotes the Uniswap V3 pool via a QuoterV2 exact-in simulation, plus the terminal fee. USD figures use a sanity-checked ETH/USD rate and are omitted when price sources disagree.

prepare_buy Builds the unsigned transaction that buys a token with ETH, routed to its live venue automatically. A bonding token buys on its curve. Everything else goes through the audited YOINK V4 router with best-price routing across the Uniswap V3 fee tiers. Returns to, value, and data plus a review block: spend in USD and ETH, quoted receive, minimum received, fee, max slippage. Pass your wallet address as from and it preflights your balance and dry-runs the exact transaction on-chain before anyone signs.

prepare_sell The same, for selling a token back to ETH. A sell can take two signatures, an exact-amount approval and then the sell. The plan field lists the legs in signing order, and the quoted receive is net of the on-chain fee. Pass from to check the live allowance, preflight the balance, and dry-run before signing.

launch_token Builds the unsigned transaction that launches a new token through the YOINK bonding-curve factory: fixed 1B supply, no upfront liquidity needed, a flat 0.0005 ETH fee verified on-chain before every build, and an optional creator first buy. Trading starts on the curve immediately. At 4.2 ETH raised the token graduates, a Uniswap V3 pool is created, and the LP position is locked forever. Returns to, value, and data plus a plain-language review block. Pass your wallet address as from and it dry-runs the exact transaction against the chain before anyone signs.

Coverage

The graph indexes launches as they land: bonding-curve launches, launchpad launches, factory deploys, and raw contract deploys. Coverage is broad but not yet exhaustive across every venue on the chain. The tools report what was actually indexed rather than implying more. Launches built through this MCP are labeled as agent launches on yoinkai.fun.

Notes

• Zero dependencies, Node >= 18, speaks MCP over stdio.
• YOINK_API overrides the graph endpoint. Default is https://yoink-graph.fly.dev.
• The server holds no keys and never broadcasts a transaction. Not financial advice.
