Module binding_cache 

Owner-isolated live MCP bindings with caller-owned, single-flight refresh.

This is a trusted-host cache, not an execution or credential grant. The connector must launch from the supplied immutable environment and credential revision, not re-read ambient state. Dropping that connector future must cancel its partially established transport. No refresh task is detached.

Structs

ConnectedMcpServer

Host connector output after successful, complete tool discovery. The cache checks server identity, completeness and every compiled descriptor.

McpBinding

One owned live connection. Retain this lease for the entire tool call.

McpBindingCache

Shared across runs, but never across distinct owner/config/auth/env keys.

McpBindingEnvironment

Exact host-selected environment, including inherited variables and cwd.

McpBindingKey

Exact reuse identity. Private fields prevent omission of owner or revisions.

McpBindingRequest

One immutable connection request, created after host policy projection.

McpBindingTicket

Generation pinned during host preflight. Old steps cannot revive a revoked binding by looking up the same key after invalidation.

Enums

McpBindingError

Secret-free cache outcome, shared by all callers of one connection attempt.
