tools/list

What it would do

Seven tools. Your agent calls them before any buy. Six run on this page right now against public data; one needs more work.

#	Tool	What it does	Status
01	check_mint_authority	Can anyone still print more of it? Read from the mint account.	Live data
02	check_freeze_authority	Can anyone freeze your tokens so you cannot sell them?	Live data
03	check_extensions	Token-2022 traps: permanent delegate, transfer hooks, transfer fees, frozen by default.	Live data
04	top_holders	How much of the supply the largest wallets hold.	Live data
05	get_liquidity	Pool liquidity, pool age and 24 hour volume across every pair.	Live data
06	can_sell	Asks for a real sell quote back to SOL. No route out, no buy.	Live data
07	check_lp_lock	Whether the pool tokens are burned or locked, and until when.	Buildable now

Connect

One block in your MCP client's config. The package is not published yet; this is what it will look like.

01Read only. It holds no keys and signs nothing.
02Every answer carries the raw value behind each flag, never a single score.
03A failed check blocks the buy unless you say go anyway.
