ChatYug MCP — AI assistants for Messaging and CRM

ChatYug MCP lets you connect an MCP-compatible AI assistant (for example Claude, ChatGPT, or Gemini CLI) to your ChatYug account. You can ask it in plain language to search contacts, send a template, update a label, or check delivery — using the same Messaging and CRM capabilities you already have in the portal.

What you can ask an assistant to do

With ChatYug MCP connected, typical requests include:

  • Contacts and CRM — find people, export lists, update names or labels, create and manage contact groups
  • Messaging — send text, template, or media messages; check whether a message was delivered
  • Conversations — open recent chats and review message history
  • Bulk imports — import contacts carefully; ChatYug asks you to confirm before large changes run

Your assistant only acts within the WhatsApp Business Account linked to the API key you used to create the MCP token.

How to turn it on in ChatYug

  1. Sign in to ChatYug and open API Configuration.
  2. Make sure you have an API key for your WhatsApp Business Account.
  3. Ask support (or your admin) to enable MCP / AI Assistants for your account if it is not already on.
  4. Optional for CLI tools: in MCP Tokens, click Generate MCP Token, copy the mcp_ value once, and store it safely.

Connect your AI assistant

ChatYug MCP connector URL: https://mcp.chatyug.com/mcp

Claude.ai / Claude Desktop (recommended)

  1. Open Settings → Connectors → Add custom connector.
  2. Name: e.g. ChatYug.
  3. Remote MCP server URL: https://mcp.chatyug.com/mcp.
  4. Leave OAuth Client ID and OAuth Client Secret empty (ChatYug registers Claude automatically).
  5. Click Add, then Connect.
  6. Sign in with your ChatYug username and password on the ChatYug authorize page and click Allow.

Claude’s Custom Connector feature may require a paid Claude subscription. That is Claude’s rule, not a ChatYug plan limit.

Sending images / media from Claude.ai

Claude stores attached files in a code-execution sandbox. To send the original file over WhatsApp (without slow base64 chunking), do this once:

  1. Open Claude Settings → Capabilities → Code execution and file creation → Additional allowed domains.
  2. Add mcp.chatyug.com and save.
  3. In chat, ask Claude to send the attached image via ChatYug. It will call prepare_media_upload, then curl the file to ChatYug, then send.

If your organization blocks allowlisting domains: Claude will give you a short-lived ChatYug upload link — open it in your normal browser, pick the original file, then tell Claude to continue. Do not ask Claude to compress or re-encode the file.

Claude Code / other CLI tools (Bearer token)

Generate an MCP token in the portal, then:

claude mcp add --transport http chatyug https://mcp.chatyug.com/mcp --header "Authorization: Bearer mcp_YOUR_TOKEN"

Same pattern works for Gemini CLI and other clients that accept a custom Authorization header.

Where do I paste an mcp_ token?

Only for CLI / Request-header style clients — not required for Claude.ai Connect (that uses ChatYug sign-in).

  • Do not put the token in the connector Name or URL.
  • Do not put the token in Claude’s OAuth Client ID / Secret boxes.
  • Optional: Claude Request headers beta can still use authorization = Bearer mcp_….

ChatGPT

  1. Turn on Developer mode if required for your plan.
  2. Create a custom connector with URL https://mcp.chatyug.com/mcp.
  3. If ChatGPT starts an OAuth / sign-in flow, complete ChatYug login on the authorize page.
  4. If it asks for API key / Bearer instead, use Bearer mcp_YOUR_TOKEN from the portal.

Gemini

Gemini web — Connected Apps (custom app)

Gemini requires a static OAuth Client ID and Client secret (unlike Claude, which auto-registers).

  1. In Gemini, open Set up a custom connected app, enter URL https://mcp.chatyug.com/mcp, expand Advanced settings.
  2. Click Copy redirect URI.
  3. Open https://mcp.chatyug.com/oauth/gemini-setup, paste that redirect URI, and create credentials.
  4. Paste the generated Client ID and Client secret into Gemini Advanced settings → Next.
  5. Sign in with your ChatYug username/password and click Allow.

Gemini CLI

gemini mcp add chatyug https://mcp.chatyug.com/mcp --transport http --header "Authorization: Bearer mcp_YOUR_TOKEN"

Gemini Enterprise custom MCP datastore

Same ChatYug OAuth endpoints: Authorization https://mcp.chatyug.com/oauth/authorize, Token https://mcp.chatyug.com/oauth/token. Create Client ID/Secret via the Gemini setup page (use redirect https://vertexaisearch.cloud.google.com/oauth-redirect if that is what Google shows).

Other MCP-compatible assistants

Prefer OAuth Connect when the client supports it (same URL). Otherwise use URL + Authorization: Bearer mcp_YOUR_TOKEN.

Plans and safety

  • Trial — your assistant can look up and list information (read-only).
  • Monthly or Annual — your assistant can also send messages and update CRM data as allowed by ChatYug. Platform fees: see ChatYug pricing.
  • Never share your MCP token in chat, email, or public docs.
  • Revoke any token that might have been exposed.
  • Large imports require an extra confirmation step so accidental bulk changes are harder.

How ChatYug MCP compares

Hosted BSP MCP products, DIY open-source Cloud API MCP servers, and unofficial WhatsApp Web MCP projects all appear in the market. ChatYug MCP is an India-focused Meta BSP connector for Messaging and CRM (Claude OAuth Connect + Bearer mcp_ for CLI). For a category comparison table and official-vs-unofficial guidance, see ChatYug MCP overview and WhatsApp MCP in India 2026. ChatYug does not claim to be the first BSP with MCP.

FAQ

Marketing FAQs (what MCP is, Claude connect, trial read-only, official vs unofficial) live on the product page: ChatYug MCP FAQ. Keep this guide for setup steps; use the landing FAQ as the canonical Q&A set for search and AI citation.

For technical setups

CLI / static header:

Authorization: Bearer mcp_YOUR_TOKEN

OAuth access tokens from Connect use the mcat_ prefix and are issued after ChatYug sign-in. Do not put tokens in the URL query string.
