Functions

func Build added in v0.0.13 

func Build(declarations []Declaration) (string, error)

Build serializes the narrowest header version that can represent the declarations. Headers remain v1 unless at least one channel advertises the v2-only stateless capability.

func BuildV1 

func BuildV1(declarations []Declaration) (string, error)

BuildV1 serializes the exact v1 header shape after validating that every declaration is canonical, unique, and within the protocol bounds.

Types

type Declaration 

type Declaration struct {
	Name            string
	Stateless       bool
	ProcessAffinity bool
}

Declaration is one canonical MCP channel name and its advertised capabilities. Stateless and ProcessAffinity are independent: a channel may accept self-contained requests while still requiring one tunnel-client process for application-local state.
