quickmcp build config --spec-url https://petstore.swagger.io/v2/swagger.json --output-path ./config
# Build a Claude Desktop extension (.mcpb) with AI-generated metadata
quickmcp build ce --spec-url https://api.example.com/swagger.json -m --author-name "Your Company"
# Build extension from existing config file
quickmcp build ce -c path/to/config.json -m -k YOURGEMINIAPIKEY
# Serve using a configuration file
quickmcp serve --config-path ./config/mcpserverconfig.json
# Add authentication to your configuration
quickmcp build config --spec-url https://api.example.com/swagger.json --auth bearer
# Add a server configuration for quick access
quickmcp add server /path/to/config.json -n MyServer
# List available servers
quickmcp list server
# Serve installed server
quickmcp serve -i myServer
# Remove a stored server configuration
quickmcp delete server MyServer
### Library Integration Example
csharp
// Create and configure a server
var serverInfoBuilder = McpServerInfoBuilder.ForOpenApi()
.FromUrl("https://petstore.swagger.io/v2/swagger.json")
.WithBaseUrl("https://petstore.swagger.io")
.AddDefaultHeader("User-Agent", "QuickMCP Client")
.AddAuthentication(new ApiKeyAuthenticator("your-api-key", "X-API-Key", "header"));
