How to use Sembly MCP with Cursor IDE

Once you have enabled Sembly MCP access and created an MCP token, you can easily add the Sembly MCP server to the Cursor IDE.

Quick setup

1. Follow the install link:

If your account data resides in the United States 🇺🇸

2. Allow the web browser to open the Cursor IDE

3. Cursor will show the MCP server configuration preview. In the “Headers” section under the “Authorization” key, replace the value part <Your MCP Token>with the token value created in the Sembly webapp.

4. The Sembly MCP server will appear in the “Installed MCP Servers” list with tools enabled.

Manual setup

You can install Cursor MCP server by manually modifying JSON configuration.

1. In Cursor IDE, open File → Preferences → Cursor Settings:

   

2. Switch to “Tools & MCP” tab and click “Add Custom MCP”:

   

3. In the opened mcp.json configuration file, add entry for Sembly MCP Server, replacing TOKEN_VALUE with token value created in Sembly web app:

   • If your account data resides in the United States

       "mcpServers": {
         ...
         
         "SemblyAI": {
           "type": "streamable-http",
           "url": "https://mcp.sembly.ai/mcp",
           "headers": {
             "Authorization": "Bearer TOKEN_VALUE"
           }
         }
         
         ...
       }
     

   • If your account data resides in the European Union

       "mcpServers": {
         ...
         
         "SemblyAI": {
           "type": "streamable-http",
           "url": "https://mcp-eu.sembly.ai/mcp",
           "headers": {
             "Authorization": "Bearer TOKEN_VALUE"
           }
         }
         
         ...
       }
     

   

4. Save file and switch back to “Cursor Settings”. Sembly MCP server appears in the “Installed MCP Servers” list:

   

Troubleshooting

Sembly MCP server stuck in “Loading tools” state

Sometimes during MCP server installation or after Cursor IDE restart, the server may get stuck in “Loading tools” state:

Solution: Disable the server via the toggle switch, wait a few seconds, and enable it again to force Cursor to reconnect. If the issue persists, please contact our Sembly AI Support Team.

Use cases

With the Sembly MCP server installed, you can cross-reference your team discussions with your codebase, recall spoken details, and trace decisions without leaving your IDE.

You can get grounded answers based on your Sembly meetings in the context of the codebase, for example:

1. According to Alex’s update today, why was @post_processor.py producing an IndexError?
2. Remind me of yesterday’s design call, what error text should the endpoint return when a user didn’t provide their role?
3. Dan said there was some issue @component.ts, what was it?
4. List my relevant tasks related to refactoring in this repository.

Here are a few real examples of how the Sembly development team uses Sembly MCP:

1. Recalling details about the existing solution

   

2. Incorporating meeting discussions into code solutions

   

3. Planning development based on tasks from Sembly meetings
