schwab_get_account_numbers
shallowio.github.lonniev/schwab-mcp · Verify this server
List Schwab account numbers and their hash identifiers. Call after completing OAuth. Returns accounts with hash values needed for brokerage data tools. Then call ``update_patron_credential(field="account_hash", value=<hash>)`` to set your preferred account. Free (no api_sats deducted) but **proof-gated**: the caller must prove Schnorr-control of ``npub`` via ``request_npub_proof`` + ``receive_npub_proof`` first, then pass the resulting token here. Without the proof check, an attacker who knew a patron's public npub could fetch that patron's Schwab account hashes (IDOR).
