Z-API

What your agent can do

Z-API gives your agent 27 tools it calls directly — pick the ones it needs, in Claude, Cursor, or any MCP client.

• →send_text — Send a text message via WhatsApp
• →send_image — Send an image message via WhatsApp
• →send_document — Send a document via WhatsApp

// Your agent calls a tool directly — no glue code.
// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
const result = await session.call("send_text", { /* ... */ });

Install

$ npm install @codespar/mcp-z-api

Quickstart

Add this entry to your claude_desktop_config.json (or any MCP-compatible client config).

{
  "mcpServers": {
    "z-api": {
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-z-api"
      ],
      "env": {
        "ZAPI_TOKEN": "<your_zapi_token>"
      }
    }
  }
}

After restart, your agent can call any of the 27 tools below — try send_text first.
