zcash-mcp

Zcash MCP server. Connects AI agents to shielded Zcash operations. Published on the MCP registry.

MCP (Model Context Protocol) is the standard way for AI models to call external tools. This server exposes 12 Zcash tools that any MCP client can use - Claude Desktop, ChatGPT, OpenClaw, or anything that speaks the protocol.

Tools

Install

npx @frontiercompute/zcash-mcp

Or install globally:

npm install -g @frontiercompute/zcash-mcp

Configuration

Environment variables:

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "zcash": {
      "command": "npx",
      "args": ["@frontiercompute/zcash-mcp"],
      "env": {
        "ZEBRA_RPC_URL": "http://127.0.0.1:8232",
        "ZAP1_API_KEY": "your-key-here"
      }
    }
  }
}

Any MCP client

The server communicates over stdio using JSON-RPC. Point your MCP client at the zcash-mcp binary.

Build from source

git clone https://github.com/Frontier-Compute/zcash-mcp.git
cd zcash-mcp
npm ci
npm run build
node dist/index.js

Testing

Offline verification covers the built stdio server and a clean-room install from the packed npm tarball:

npm run test:offline

Live verification hits a real Zebra RPC and ZAP1 API:

ZEBRA_RPC_URL=http://127.0.0.1:8232 \
ZAP1_API_URL=http://127.0.0.1:3080 \
ZAP1_API_KEY=your-key-here \
npm run test:live

test:live drives the MCP server over stdio and exercises the live tool surface, not just the underlying HTTP endpoints. Set ZAP1_AGENT_ID if you want the get_agent_status check to target a specific deployed agent.

GitHub Actions mirrors that split:

• .github/workflows/offline-ci.yml runs deterministic packaging and MCP handshake checks on every push and pull request.
• .github/workflows/live-e2e.yml runs secret-backed live checks on main, on a schedule, and by manual dispatch.

Dependencies

• A running Zebra node for chain queries (get_block_height, lookup_transaction)
• The ZAP1 API at pay.frontiercompute.io for attestation tools (get_balance, attest_event, verify_proof, get_stats, get_anchor_history, get_anchor_status, get_events, get_agent_status)
• Memo decoding works locally with no external dependencies

quickstart (5 minutes)

add to your MCP config:

{
  "mcpServers": {
    "zcash": {
      "command": "npx",
      "args": ["@frontiercompute/zcash-mcp"]
    }
  }
}

restart your client. ask: "what is the current zcash block height?"
