Zoho Projects MCP Server

An enhanced Model Context Protocol (MCP) server for Zoho Projects API integration. This server enables AI assistants to interact with Zoho Projects for managing projects, tasks, issues, milestones, comments, attachments, and more.

Note: This is an enhanced fork with additional features for task lookup by prefix, tasklist management, comments, attachments, and inline image handling. Based on qpiai/zoho-projects-mcp.

Prerequisites

1. Node.js (v18 or higher)

2. Zoho Projects Account with API access

3. Zoho OAuth Credentials

Setup

1. Get Zoho OAuth Credentials (Detailed Guide)

Step 1: Create a Zoho Developer Application

1. Go to Zoho API Console

2. Click "Add Client" button

3. Choose "Self Client" (recommended for personal use) or "Server-based Applications"

4. Fill in the application details:

   • Client Name: e.g., "Zoho Projects MCP"

   • Homepage URL: Your website or http://localhost for testing

   • Authorized Redirect URIs: http://localhost:8080/callback (or your preferred redirect URL)

5. Click "Create" and note down:

   • Client ID (e.g., 1000.XXXXXXXXXX)

   • Client Secret (keep this secure!)

Step 2: Generate Authorization Code

1. Build the authorization URL with required scopes:

   https://accounts.zoho.{REGION}/oauth/v2/auth?
     scope=ZohoProjects.portals.ALL,ZohoProjects.projects.ALL,ZohoProjects.tasks.ALL,ZohoProjects.bugs.ALL,ZohoProjects.milestones.ALL,ZohoProjects.users.READ,ZohoSearch.securesearch.READ
     &client_id=YOUR_CLIENT_ID
     &response_type=code
     &access_type=offline
     &redirect_uri=YOUR_REDIRECT_URI

   Replace {REGION} with your region:

   • US: com

   • EU: eu

   • IN: in

   • AU: com.au

   • CN: com.cn

2. Open this URL in your browser

3. Log in to your Zoho account and authorize the application

4. You'll be redirected to your redirect URI with a code parameter in the URL:

   http://localhost:8080/callback?code=1000.XXXXX.XXXXX&location=in&accounts-server=https://accounts.zoho.in

5. Copy the code value (valid for ~2 minutes, use it immediately!)

Step 3: Exchange Code for Tokens

Use this curl command to get your access and refresh tokens:

curl -X POST https://accounts.zoho.{REGION}/oauth/v2/token \
  -d "code=YOUR_AUTHORIZATION_CODE" \
  -d "client_id=YOUR_CLIENT_ID" \
  -d "client_secret=YOUR_CLIENT_SECRET" \
  -d "redirect_uri=YOUR_REDIRECT_URI" \
  -d "grant_type=authorization_code"

Response will contain:

{
  "access_token": "1000.xxxx.yyyy",
  "refresh_token": "1000.zzzz.aaaa",
  "expires_in": 3600,
  "api_domain": "https://www.zohoapis.in",
  "token_type": "Bearer"
}

Important: Save both tokens:

• access_token: Valid for 1 hour (auto-refreshed by the server)

• refresh_token: Long-lived, used to get new access tokens

Step 4: Find Your Portal ID

Method 1: From URL

1. Go to your Zoho Projects in browser

2. Look at the URL: https://projects.zoho.{REGION}/portal/{PORTAL_ID}/...

3. The number after /portal/ is your Portal ID (e.g., 60028147039)

Method 2: Using API

curl -X GET https://projectsapi.zoho.{REGION}/api/v3/portals \
  -H "Authorization: Zoho-oauthtoken YOUR_ACCESS_TOKEN"

Response will list all your portals with their IDs.

Step 5: Verify Credentials

Test your setup with this API call:

curl -X GET https://projectsapi.zoho.{REGION}/api/v3/portal/YOUR_PORTAL_ID/projects \
  -H "Authorization: Zoho-oauthtoken YOUR_ACCESS_TOKEN"

Expected: JSON response with your projects list If error: Check token, portal ID, and API domain match your region

Required Scopes Summary

Make sure your OAuth token has these scopes:

• ✅ ZohoProjects.portals.ALL - Portal operations

• ✅ ZohoProjects.projects.ALL - Project management

• ✅ ZohoProjects.tasks.ALL - Task management

• ✅ ZohoProjects.bugs.ALL - Issue/bug management

• ✅ ZohoProjects.milestones.ALL - Milestone/phase management

• ✅ ZohoProjects.users.READ - User information

• ✅ ZohoSearch.securesearch.READ - Search functionality

OAuth Token Management

Token Expiration

Access tokens expire after 1 hour (3600 seconds). This MCP server automatically refreshes tokens using the refresh token.

Manual Token Refresh

If you need to manually refresh your access token:

# For India region (accounts.zoho.in)
curl -X POST https://accounts.zoho.in/oauth/v2/token \
  -d "refresh_token=YOUR_REFRESH_TOKEN" \
  -d "client_id=YOUR_CLIENT_ID" \
  -d "client_secret=YOUR_CLIENT_SECRET" \
  -d "grant_type=refresh_token"

# For other regions, use the appropriate accounts domain:
# US: https://accounts.zoho.com/oauth/v2/token
# EU: https://accounts.zoho.eu/oauth/v2/token
# AU: https://accounts.zoho.com.au/oauth/v2/token
# CN: https://accounts.zoho.com.cn/oauth/v2/token

Response example:

{
  "access_token": "1000.xxx.yyy",
  "scope": "ZohoProjects.portals.ALL ZohoProjects.projects.ALL...",
  "api_domain": "https://www.zohoapis.in",
  "token_type": "Bearer",
  "expires_in": 3600
}

Automatic Token Refresh

The MCP server automatically handles token refresh. Configure the following environment variables:

ZOHO_REFRESH_TOKEN=your_refresh_token_here
ZOHO_CLIENT_ID=your_client_id_here
ZOHO_CLIENT_SECRET=your_client_secret_here
ZOHO_ACCOUNTS_DOMAIN=https://accounts.zoho.in  # Match your region

The server will automatically refresh the access token before it expires.
