Connecting LLM Clients

Once your MCP server is running, configure your LLM client to connect to it.

Prerequisites

Before configuring any client, ensure:

1. Your MCP server is running and accessible (e.g., http://localhost:8080/mcp)
2. You know the authentication token if your server requires one
3. The endpoint path matches your TJRPCDispatcher.PathInfo setting

LM Studio

LM Studio supports HTTP-based MCP servers natively.

Configuration file location:

• Windows: %USERPROFILE%\.lmstudio\mcp.json
• macOS/Linux: ~/.lmstudio/mcp.json

{
  "mcpServers": {
    "delphi-mcp-server": {
      "url": "http://localhost:8080/mcp",
      "headers": {
        "Authorization": "Bearer my-secret-token"
      }
    }
  }
}

Parameter	Description
delphi-mcp-server	A unique identifier for your server (any name)
url	The full URL to your MCP server endpoint
headers	Optional HTTP headers (e.g., for authentication)

After saving the configuration, restart LM Studio to load the new MCP server.

Claude Desktop

Claude Desktop currently requires an intermediate tool called mcp-remote to connect to HTTP-based MCP servers.

Step 1: Test the Connection

Before configuring Claude Desktop, verify that mcp-remote can connect to your server:

npx mcp-remote http://localhost:8080/mcp --header "Authorization: Bearer my-secret-token"

If successful, you should see your server's capabilities listed.

Step 2: Configure Claude Desktop

Configuration file location:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "my-demo-server": {
      "command": "C:\\Program Files\\nodejs\\npx",
      "args": [
        "-y",
        "mcp-remote",
        "http://localhost:8080/mcp",
        "--header",
        "Authorization: Bearer my-secret-token"
      ]
    }
  }
}

Parameter	Description
my-demo-server	A unique identifier for your server
command	Path to npx (Windows: C:\\Program Files\\nodejs\\npx, macOS/Linux: npx)
-y	Auto-confirm package installation
mcp-remote	Bridge tool for HTTP transport

Step 3: Restart Claude Desktop

After saving the configuration, restart Claude Desktop to load the MCP server connection.
