Zcash Mcp

Wraps the ZAP1 attestation protocol for Zcash workflows. Agents can create typed attestation leaves, anchor them to Zcash via Merkle roots, and generate verifiable receipts for payment proofs, lifecycle events, or policy decisions. The server deliberately excludes wallet operations like key custody, balance scanning, and PCZT signing. Instead it focuses on the proof layer: hash an action, commit it to a leaf, anchor the root on chain, hand off a receipt packet that any verifier can check without trusting the original agent. Useful when you need cryptographic receipts around Zcash workflows rather than just transaction lookups. Start with zcash_receipt_template to wire up agent actions, payment receipts, or operator lifecycle events, then use attest_event and verify_proof to manage the proof lifecycle.
