How to Connect MCP Servers to Claude Desktop

What you need

• Claude Desktop installed (macOS or Windows)
• An MCP server endpoint (we'll create one with DataFaucet)

Claude Desktop supports MCP natively. You add servers to a JSON config file and Claude discovers the tools automatically.

Step 1: Find your config file

macOS:

~/Library/Application Support/Claude/claude_desktop_config.json

Windows:

%APPDATA%\Claude\claude_desktop_config.json

If the file doesn't exist, create it with an empty JSON object:

{}

Step 2: Create an MCP server with DataFaucet

Go to DataFaucet and paste any URL (e.g., your Jira instance, Notion workspace, or internal dashboard). Browse the app for 30 seconds while DataFaucet captures the API calls. Click Deploy.

You'll get an SSE endpoint like:

https://datafaucet.dev/api/mcp/abc123/sse

Step 3: Add the server to your config

Open claude_desktop_config.json and add your server under the mcpServers key:

{
  "mcpServers": {
    "my-jira": {
      "url": "https://datafaucet.dev/api/mcp/abc123/sse"
    }
  }
}

You can add multiple servers:

{
  "mcpServers": {
    "jira": {
      "url": "https://datafaucet.dev/api/mcp/abc123/sse"
    },
    "notion": {
      "url": "https://datafaucet.dev/api/mcp/def456/sse"
    },
    "datadog": {
      "url": "https://datafaucet.dev/api/mcp/ghi789/sse"
    }
  }
}

Step 4: Restart Claude Desktop

Close and reopen Claude Desktop. It reads the config on startup.

Step 5: Verify tools are connected

Open a new conversation and look for the tools icon (hammer) in the input area. Click it to see available tools from your MCP servers. You can also ask Claude "what tools do you have access to?" and it will list them.

Troubleshooting

Tools not appearing:

• Check that the JSON is valid (no trailing commas, proper quotes)
• Verify the endpoint URL is correct and accessible
• Restart Claude Desktop fully (quit from menu bar, not just close window)

Connection errors:

• DataFaucet SSE endpoints require no additional auth (auth is baked into the server)
• Check your network allows outbound HTTPS to datafaucet.dev
• Try opening the SSE URL in a browser to verify it responds

Local servers vs hosted servers

Claude Desktop supports both:

DataFaucet servers are hosted SSE endpoints. No local process to manage, no Docker to run.

What to connect first

Most teams start with these three:

1. Project tracker (Jira, Linear, Asana) — ask Claude about tickets, sprint status
2. Documentation (Notion, Confluence) — search and summarize team docs
3. Monitoring (Datadog, Grafana) — check metrics and alerts inline

Each takes 60 seconds to create on DataFaucet's free tier (3 servers included).
