@zappimoney/zappi-mcp

Local MCP server that signs Zappi pot spends. The pot key stays in the OS keychain. The agent only sees tools.

Setup (create or pair a pot) still uses @zappimoney/zappi-cli. Spend uses this server.

{
  "mcpServers": {
    "zappi-pot": {
      "command": "npx",
      "args": ["-y", "@zappimoney/zappi-mcp"],
      "env": {
        "ZAPPI_POT_ID": "<pot id>"
      }
    }
  }
}

Do not put ZAPPI_POT_SEED in that env block. Store the key with the OS keychain (keytar, service money.zappi.mcp).
