+# Zcash MCP Server
+
+Zcash tools for AI agents. Shielded operations, structured memo decoding, lifecycle attestation via ZAP1, and chain queries. Privacy by default.
+
+## Quick Install
+
+```
+npx -y @frontiercompute/zcash-mcp
+```
+
+Or configure in `~/.config/goose/config.yaml`:
+
+```yaml
+extensions:
+  zcash-mcp:
+    name: Zcash
+    type: stdio
+    cmd: npx
+    args: ["-y", "@frontiercompute/zcash-mcp"]
+    enabled: true
+    envs:
+      ZAP1_API_URL: https://pay.frontiercompute.io
+```
+
+## Tools
+
+| Tool | Description |
+|------|-------------|
+| get_block_height | Current Zcash chain height |
+| lookup_transaction | Transaction details by txid |
+| get_balance | Wallet lifecycle and attestation status |
+| send_shielded | Generate shielded payment URI (ZIP 321) |
+| decode_memo | Decode ZAP1, ZIP 302, or plain text memos |
+| attest_event | Create a ZAP1 lifecycle attestation on Zcash |
+| verify_proof | Verify a ZAP1 Merkle proof |
+| get_stats | Protocol stats (leaves, anchors, event types) |
+| get_anchors | Anchor history with txids and block heights |
+| get_events | Recent attestation events |
+| get_agent_status | Agent attestation summary |
+| get_agent_bond | Agent bond and policy compliance status |
+
+## Example Usage
+
+Decode a Zcash shielded memo:
+```
+decode this memo: ZAP1:09:024e36515ea30efc15a0a7962dd8f677455938079430b9eab174f46a4328a07a
+```
+
+Verify an attestation proof:
+```
+verify this proof: ddbe05cc63697e1ce83c210ab4500cf1d2d4921eb863dbb40f10ec3e42c7b28c
+```
+
+Check protocol stats:
+```
+what are the current ZAP1 stats?
+```
+
+## Configuration
+
+| Variable | Description | Required |
+|----------|-------------|----------|
+| ZEBRA_RPC_URL | Zcash Zebra node endpoint | No (defaults to public endpoint) |
+| ZAP1_API_URL | ZAP1 attestation API | No (defaults to pay.frontiercompute.io) |
+| ZAP1_API_KEY | API key for write operations (attest_event) | No (read tools work without it) |
