Tools of Bitcoin PSBT, Address & Descriptor Verifier + WorkSats L402 MCP
	Description		Read-only	Idempotent	Open world
`check_bitcoin_address`Verify a Bitcoin address (Bech32m P2TR, Bech32 P2WPKH/P2WSH, Base58 P2PKH/P2SH): network, type, witness version, scriptPubKey hex, and common pitfalls. Never send private keys or seed phrases. Free tier: 2 calls/day per IP; after that, pass a WorkSats `creditToken` (`crd_...`), L402 header, or Base USDC `x402TxHash`.

`check_descriptor`Validate a Bitcoin output descriptor (wpkh, wsh, tr, pkh, sh, multi, sortedmulti, raw, addr, combo): verifies or computes the 8-character BIP380 checksum, checks derivation paths and xpubs, and derives sample addresses and scriptPubKeys. Never send xprv, WIF, or seed phrases.

`check_psbt`Inspect an unsigned or partially signed Bitcoin PSBT (BIP174 base64 or hex) before signing: decodes inputs, outputs, fee, fee rate (sat/vB), change detection, sighash types, taproot/witness scripts, and flags high-fee or missing-prevout risks.

`worksats_credits`Manage WorkSats bearer credits (`crd_...`): check `balance`, `split` credits to pay another bot, `rotate`/`merge` received tokens so the sender cannot double-spend, `mint` credits from L402 or x402 Base USDC, `bounty_create` to escrow credits for a verifiable task (`sha256`, `descriptor_derive`, `address_script`, `psbt_feerate`, `json_schema`), or view clearinghouse `stats`.

`worksats_get_task`Fetch an open buyer-funded bounty task or a deterministic house micro-task (`descriptor_checksum_and_derive`) from the WorkSats clearinghouse (`GET /v1/tasks/next`).
