Connect external tools to the AI (MCP)

Features · Updated Jul 21, 2026

You can connect outside services to RagChat so the AI can use them during a conversation, for example looking something up in your helpdesk or creating a ticket in your issue tracker. The connection uses MCP, an open standard that many tools now support.

Connected tools are available on the Pro plan.

Before you start

You need the MCP server address from the service you want to connect, and an API token if that service requires one. The service's own documentation will have both.

The address must be a public https address. RagChat will not connect to a private or internal address.

Add a connection

  1. Go to Settings → AI and find the Connected tools (MCP) section.
  2. Click Add connection.
  3. Fill in:
    • Name: how you want to recognize it. It also prefixes the tool names the AI sees.
    • Server URL: the MCP address, for example https://mcp.example.com/mcp.
    • API token: optional. Sent to the service as an authorization header. Leave it blank if the service needs no token.
    • Instructions for the AI: optional. When and how the AI should use these tools, for example "Only create an issue after collecting the customer's email."
  4. Click Add connection.

You can add up to 5 connections.

Choose which tools the AI can use

After a connection is added, RagChat reads the list of tools the service offers.

Click Tools on the connection to expand the list. Every tool is off until you turn it on, so the AI can only do what you have specifically allowed.

Click Refresh if the service adds or renames tools later, and Edit to change the name, address, token, or instructions. Edit → Remove connection deletes it.

Good to know

  • Services that require a browser sign-in (OAuth) instead of an API token are not supported on Shopify stores yet. Use a service that accepts an API token.
  • If you downgrade below Pro, your connections are kept but stop working, and the AI no longer calls their tools. They start working again if you upgrade.
  • Tools run while the AI is answering a customer, so keep the instructions field clear about when a tool should and should not be used. See Configure your AI assistant.
