What the code does

A tool parameter here reaches a dangerous call
That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.

<BAGS_API_KEY> (Bags API key from dev.bags.fm. Required for all tools).
The author’s registry entry marks it as required.
Optional settings from the registry entry, left out of the block above:
BAGS_NETWORK (Solana cluster: devnet (default) or mainnet. Writes on mainnet move real funds), SOLANA_RPC_URL (Custom Solana RPC endpoint. Defaults to the public RPC for BAGS_NETWORK), BAGS_KEYPAIR_PATH (Path to a Solana keypair JSON file. Only required for write tools), BAGS_MAX_SOL_PER_TX (Hard cap on SOL spent by any single transaction. Default 0.1), BAGS_MAX_SOL_PER_SESSION (Hard cap on total SOL spent across one server session. Default 1.0), BAGS_ALLOW_UNCONFIRMED (Set true to skip the two-step confirmation on writes. Default false), BOS_TOKEN_MINT (Mint address of the BOS token used for gating write tools), BOS_REQUIRED_BALANCE (Minimum BOS balance required to call write tools. Default 10000), BAGS_ALLOW_UNCAPPED_TOKEN_SWAPS (Permit non-SOL-input swaps, which the SOL-denominated caps cannot limit), USE_MOCK_DATA (Makes bags_get_claimable_fees return fabricated data instead of calling the API. Default false).
