💡 Key Use Cases in AI Workflows

Use Case 1: Fetching Data for Analysis

AI application developers can use the MCP server to fetch data from Supabase databases, enabling real-time data analysis within their workflows. For example, a financial analyst might integrate historical stock market data into an AI-driven predictive model.

Code Sample:

const mcpClient = require('@modelcontextprotocol/client');
const client = mcpClient.connect('your-supabase-api-key');

async function fetchData() {
  const result = await client.query({
    type: 'SELECT',
    schema: 'public',
    table: 'stocks',
    columns: ['symbol', 'price']
  });
  console.log(result);
}

Use Case 2: Uploading and Retrieving User Data

Another common use case involves uploading user-generated content to Supabase storage services. Here’s an example of how this can be achieved using the MCP server.

Code Sample:

const mcpClient = require('@modelcontextprotocol/client');
const client = mcpClient.connect('your-supabase-api-key');

async function uploadFile(file) {
  const result = await client.upload({
    bucketName: 'user-uploads',
    filePath: `uploads/${file.name}`
  });
  console.log(result);
}

❓ Frequently Asked Questions (FAQ)

1. Why is the Cursor client not fully supported by Supabase MCP Server?

   • The Cursor client currently only supports tools and prompts, but lacks full resource integration as it is more focused on natural language processing rather than data retrieval.

2. How secure are the MCP connections established through this server?

   • The Supabase MCP Server employs robust security measures including API key validation and rate limiting to ensure secure communication between clients and APIs.

3. Is there a performance difference between using tools vs full resources?

   • Tools like SQL queries often perform faster due to their lightweight nature, whereas resource-heavy operations such as large file uploads may have slower processing times.

4. How do I handle API rate limits with the Supabase MCP Server?

   • You can implement custom rate limiting logic in your client code or leverage Supabase’s built-in rate limit settings, which are enforced by the MCP server.

5. Can I customize the MCP protocol flow for specific use cases?

   • Yes, the Supabase MCP Server supports custom configurations and can be tailored to fit unique integration needs through detailed environment variable settings.
