Troubleshooting issues with Cursor client

The following issues can occur when connecting the DocSpace MCP server to the Cursor client via the local MCP server.

Docker image fails to pull​

Ensure Docker is running and you have internet access. Try pulling the image manually to see the full error message:

docker pull onlyoffice/docspace-mcp

If you are behind a corporate proxy, configure Docker to use it: Docker Desktop → Settings → Resources → Proxies.

MCP server starts but Cursor does not list any tools​

Run the container manually to check for startup errors:

docker run --interactive --rm \
  --env DOCSPACE_BASE_URL=https://your-instance.onlyoffice.com \
  --env DOCSPACE_API_KEY=your-api-key \
  onlyoffice/docspace-mcp

Review the output for error messages and fix the reported issue before reconnecting in Cursor.

Permission denied when running Docker​

On Linux, your user account may not be in the docker group. Add your user and restart the session:

sudo usermod -aG docker $USER
