Overview ¶
Package completionlayer implements the MCP completion/complete handler for the platform: argument autocompletion for prompt arguments and resource-template variables. It lives in its own facade-internal package so the platform facade stays within its size budget and the completion logic is cohesive and independently testable. It owns all value providers (dataset/topic/connection names, catalog/schema/table, glossary terms), the persona gating that mirrors tools/list visibility, and the interactive latency budget and value cap.

Constants ¶
const MaxValues = 100
MaxValues is the spec-mandated ceiling on the number of completion values returned in a single completion/complete response. A provider may find more; the handler truncates to this many and sets HasMore.

Types ¶
type Deps ¶
type Deps struct {
Authenticator middleware.Authenticator
Authorizer middleware.Authorizer // nil => no persona filtering (allow all)
PersonasForRoles middleware.PersonasForRoles
AdminPersona string
Semantic semantic.Provider
Query query.Provider
Registry *registry.Registry
PersonaRegistry *persona.Registry
// Timeout bounds the upstream lookups a completion performs. Zero uses
// defaultTimeout.
Timeout time.Duration
}
Deps carries the platform primitives the completion handler needs, kept as plain values so this package never imports the platform package (which would cycle).
type Handle ¶
type Handle struct {
// contains filtered or unexported fields
}
Handle owns the completion handler and its value providers.
func (*Handle) Handler ¶
func (h *Handle) Handler() func(context.Context, *mcp.CompleteRequest) (*mcp.CompleteResult, error)
Handler returns the completion/complete handler for ServerOptions. It resolves the caller (unauthenticated → empty), applies the interactive latency budget, and shapes the result to the spec's value cap. An unauthenticated session — or one whose lookups time out — receives an empty completion set, never an error.
