Connecting to Claude Web

You can connect your HasMCP remote MCP servers to the Claude.AI web application using the built-in Connectors feature. Once connected, Claude can call your tools and APIs directly from any conversation in the browser.

​
Prerequisites

  • A HasMCP account with at least one MCP server configured
  • A Claude.AI account (Pro or Team plan required for custom connectors)

​
Setup Instructions

1

Generate a Server Token

In your HasMCP dashboard, navigate to your MCP Server and click Generate Token to create a secure access token. Copy the token — you will need it in the next step.
2

Open Claude Connectors Settings

In the Claude.AI web app, click your profile icon in the top-right corner and select Settings. Then click Connectors in the left sidebar.You will see a list of available connectors along with an Add custom connector button.Claude Settings Connectors page showing Google Drive, GitHub Integration, and the Add custom connector button

Add Your HasMCP Server as a Custom Connector

Click Add custom connector. In the dialog that appears, enter your HasMCP server URL with your token appended as a query parameter:
https://<server-subdomain>.mcp.hasmcp.com/mcp?token=<YOUR_ACCESS_TOKEN>
Replace <server-subdomain> with your server’s subdomain and <YOUR_ACCESS_TOKEN> with the token you generated in Step 1.Add custom connector dialog with a HasMCP MCP server URL entered in the URL fieldClick Add to save the connector.

​
Why Use Query String Tokens?

The ?token=<> query string approach is recommended for Claude.AI connectors because:
  • Compatibility: It bypasses potential header-stripping issues in the Claude connector interface.
  • Simplicity: You do not need to configure a separate API key authentication step.
  • Security: The token is still validated by HasMCP before any tools are executed.

​
Troubleshooting

Ensure the URL includes the full subdomain and the ?token= query parameter. The URL must start with https://.
Ensure there are no spaces or extra characters in the ?token= value. Regenerate the token in the HasMCP dashboard if needed.
Custom connectors require a Claude Pro or Team subscription. Free accounts may not see the custom connector option.
After adding the connector, start a new conversation. Look for the tools icon in the message input area to confirm the server is connected and tools are available.
