Context Cost

~1,856Tokens (tool definitions)
~1.1 KBTypical response size
Moderate attention impact (1.45% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

⚪prepare_launch(name, symbol, marketCapUsd, marketCapPair, pair, ...)

Prepare a token launch for the person to sign on marketmayhem.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.
