# Flaunch

> Prepare Base token launches through Flaunch and trade deployed Flaunch tokens with Base MCP.

Flaunch is a token launch and discovery surface for Base memecoins. The plugin uses `mcp.flaunch.gg` to upload media, prepare launch metadata, discover launched coins, and build Base-compatible transaction previews. Base MCP handles the approval and submission.

**Chain:** Base mainnet.

**Operations:** media upload, token launch preparation, new coin discovery, token lookup, token buys, and token sells.

<Tip>
  Launches and swaps are irreversible. New tokens can have thin liquidity, so the assistant confirms token details and slippage-sensitive trades before calling Base MCP tools.
</Tip>

## Try it

```text Launch theme={null}
Launch a memecoin on Base
```

```text Discover theme={null}
Show me the newest Flaunch coins
```

```text Buy theme={null}
Buy 0.001 ETH of a Flaunch coin
```

## Pattern

For launches, the assistant confirms name, symbol, description, image, creator address, and social URLs, then calls `POST /v1/base/launch/prepare`. The returned `input` is already in Base MCP `send_calls` shape.

For deployed token trades, the assistant resolves the token address from Flaunch discovery or user input and uses Base MCP `swap` with `chain: "base"`. If `swap` cannot route the token, the assistant stops instead of inventing raw calldata.
