Use these steps to connect Flow MCP Server in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "flow-mcp-server-lmcmz": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-flow-mcp-server-lmcmz"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "flow-mcp-server-lmcmz": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-flow-mcp-server-lmcmz"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "flow-mcp-server-lmcmz": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-flow-mcp-server-lmcmz"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "flow-mcp-server-lmcmz": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-flow-mcp-server-lmcmz"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "flow-mcp-server-lmcmz": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-flow-mcp-server-lmcmz"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
  "mcpServers": {
    "flow-mcp-server-lmcmz": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-flow-mcp-server-lmcmz"
      ]
    }
  }
}
