Step 3 — Verify the Server

bash claude mcp list Shows configured servers. Each should be marked ✓ healthy.

Step 4 — Use the Tools

Open Claude Code, ask: "List open PRs in onurhuseyinkocak/vibecodingturkey" Claude detects the relevant tool, calls it, summarizes.

Step 5 — Build a Custom Server

Use the Anthropic MCP SDK (Python or TypeScript): python from mcp.server import Server server = Server("my-server") @server.tool("countusers") async def countusers(): return {"count": 42} Register in /.claude/settings.json: json { "mcpServers": { "my-server": { "command": "python", "args": ["/path/to/myserver.py"] } } }

Step 6 — Troubleshoot

If claude mcp list shows a server as unhealthy: - Check the command path - Check stderr in /.claude/logs/mcp/my-server.log - Verify the SDK version matches Claude Code's expected protocol

The protocol is free. Server fees depend on the provider (e.g., GitHub MCP free, Stripe MCP free, paid services may charge).

Read [What is MCP](https://vibecodingturkey.com/en/rehberler/what-is-mcp) for the protocol theory.
