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.

zcash-mcp
ZAP1 receipts for Zcash agents: verify workflows without trusting the server.
ZAP1 is an attestation and proof rail for Zcash workflows. Frontier Compute maintains the reference ZAP1 implementation.
A wrapper makes you trust the server. ZAP1 makes the server unnecessary to trust.
Core rule: observe state, bound the claim, hash evidence, issue a receipt, verify later.
MCP is the standard way for AI agents to call external tools. zcash-mcp
exposes the ZAP1 attestation layer for agents that need verifiable receipts
around Zcash workflows: create ZAP1 attestation leaves, query anchor state,
and verify proof receipts.
