flags.

const (

	EntityTypeRes    = "resource"
)

entity types.

Variables

var (
	// FormatOption is the format option for the command, valid values are "table", "json", and
	// "pretty".
	FormatOption string
	// ParamsString is the params for the command.
	ParamsString string

var CreateClientFunc = func(args []string) (*client.Client, error) {
	if len(args) == 0 {
		return nil, ErrCommandRequired
	}

	isHTTP := func(str string) bool {
		return strings.HasPrefix(str, "http://") || strings.HasPrefix(str, "https://")
	}

		server, found := alias.GetServerCommand(args[0])

		return client.NewHTTP(args[0]), nil

	return client.NewStdio(args), nil
}

CreateClientFunc is the function used to create MCP clients. This can be replaced in tests to use a mock transport.

var (
	ErrCommandRequired = fmt.Errorf("command to execute is required when using stdio transport")
)

sentinel errors.

var Version = "dev"

Version information placeholder.

Functions

func AliasCmd

func AliasCmd() *cobra.Command

AliasCmd creates the alias command.

func CallCmd

func CallCmd() *cobra.Command

CallCmd creates the call command.

func FormatAndPrintResponse

func FormatAndPrintResponse(cmd *cobra.Command, resp map[string]any, err error) error

FormatAndPrintResponse formats and prints an MCP response in the format specified by FormatOption.

func GetPromptCmd

func GetPromptCmd() *cobra.Command

GetPromptCmd creates the get-prompt command.

func LoadProxyConfig

func LoadProxyConfig() (map[string]map[string]string, error)

LoadProxyConfig loads the proxy configuration from the config file.

func MockCmd

func MockCmd() *cobra.Command

MockCmd creates the mock command.

func NewCmd

func NewCmd() *cobra.Command

NewCmd returns a new 'new' command for scaffolding MCP projects.

func ProcessFlags

func ProcessFlags(args []string) []string

ProcessFlags processes command line flags, sets the format option, and returns the remaining arguments. Supported format options: json, pretty, and table.

For example, if the input arguments are ["tools", "--format", "pretty", "npx", "-y", "@modelcontextprotocol/server-filesystem", "~"], it would return ["npx", "-y", "@modelcontextprotocol/server-filesystem", "~"] and set the format option to "pretty".

func ProxyStartCmd

func ProxyStartCmd() *cobra.Command

ProxyStartCmd creates the proxy start command.

func ProxyToolCmd

func ProxyToolCmd() *cobra.Command

func ResourcesCmd

func ResourcesCmd() *cobra.Command

ResourcesCmd creates the resources command.

func RootCmd

func RootCmd() *cobra.Command

RootCmd creates the root command.

func SaveProxyConfig

func SaveProxyConfig(config map[string]map[string]string) error

Types

type MockTransport

type MockTransport struct {
	ExecuteFunc func(method string, params any) (map[string]any, error)
}

MockTransport implements the transport.Transport interface for testing.

func (*MockTransport) Execute

func (m *MockTransport) Execute(method string, params any) (map[string]any, error)

Execute calls the mock implementation.
