zoho-books-mcp

A Model Context Protocol (MCP) server that gives Claude (and any MCP-compatible AI assistant) full access to the Zoho Books accounting API.

Manage invoices, bills, contacts, sales orders, purchase orders, payments, journal entries, and more — all through natural language.

Features

57 tools covering every major Zoho Books resource
Works with Claude Desktop, Claude Code, Cursor, and any MCP-compatible client
OAuth access token authentication — per-request or via environment variable
Multi-region support: com, eu, in, com.au, sa
TypeScript-first with Zod runtime validation
Zero-dependency runtime (only @modelcontextprotocol/sdk and zod)

Configuration

Get your OAuth access token

Zoho Books uses OAuth 2.0. To get an access token:

Go to Zoho API Console
Create a Self Client (for personal use) or a Server-based Application
Generate an access token with the scope ZohoBooks.fullaccess.all
Copy your access token and organization ID (found in Zoho Books under Settings → Organization Profile)

Note: Access tokens expire every hour. Use a refresh token flow or a long-lived token for production use.

Set environment variables (recommended)

export ZOHO_ACCESS_TOKEN=your_access_token_here
export ZOHO_ORGANIZATION_ID=your_organization_id_here

Or add them to your shell profile (~/.zshrc, ~/.bashrc).

Per-request credentials

Every tool also accepts optional access_token and organization_id parameters, which take precedence over environment variables. This is useful when working with multiple Zoho Books organizations.

Region

The server defaults to the com (US/global) data center. Set the region parameter per tool call if your account is on a different data center:

| Region | Data Center | |---|---| | com | United States / Global (default) | | eu | Europe | | in | India | | com.au | Australia | | sa | Saudi Arabia |

Usage with Claude Desktop

Add this to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "zoho-books": {
      "command": "npx",
      "args": ["-y", "zoho-books-mcp"],
      "env": {
        "ZOHO_ACCESS_TOKEN": "your_access_token_here",
        "ZOHO_ORGANIZATION_ID": "your_organization_id_here"
      }
    }
  }
}

Usage with Claude Code

claude mcp add zoho-books -- npx -y zoho-books-mcp

Then set your credentials:

export ZOHO_ACCESS_TOKEN=your_access_token_here
export ZOHO_ORGANIZATION_ID=your_organization_id_here

Usage with Cursor

Add to .cursor/mcp.json in your project root (or ~/.cursor/mcp.json globally):

{
  "mcpServers": {
    "zoho-books": {
      "command": "npx",
      "args": ["-y", "zoho-books-mcp"],
      "env": {
        "ZOHO_ACCESS_TOKEN": "your_access_token_here",
        "ZOHO_ORGANIZATION_ID": "your_organization_id_here"
      }
    }
  }
}

Example Prompts

Once connected, you can ask Claude things like:

"List all unpaid invoices"
"Create an invoice for customer ID 123 with 2 units of item 456 at 500 SAR each"
"Show me all overdue bills"
"Create a journal entry debiting account 1001 and crediting account 2001 for 10000"

"List all purchase orders with status open"
"What taxes are configured in my account?"
"Show me the chart of accounts"
