## Deprecated Features

The 2026-07-28 spec revision deprecates Roots, Sampling, and Logging (SEP-2577).
These features remain fully supported throughout 1.x, and the SDK emits deprecation warnings when they are used
with protocol version 2026-07-28 or newer.
Under Semantic Versioning their removal requires a major release, but no removal is scheduled yet:
whether 2.0.0 removes them depends on how future MCP spec revisions treat these features
and on adoption of their replacements.
These features remain supported throughout 1.x: on the legacy lifecycle they work unchanged
(the deprecations do not apply there), and the 2026-07-28 lifecycle carries them through its own mechanisms:
roots-shaped and sampling-shaped input requests embedded in `InputRequiredResult` responses
(the SEP-2322 multi round-trip requests pattern) and per-request log delivery through the envelope's `logLevel`.
The replacements SEP-2577 names live outside the protocol: tool parameters or configuration for roots,
direct LLM provider APIs for sampling, and stderr or OpenTelemetry for logging.
The client emits a deprecation warning when a modern connect declares the deprecated Roots or Sampling capabilities.
Under Semantic Versioning their removal requires a major release, but no removal is scheduled yet: whether 2.0.0 removes
them depends on how future MCP spec revisions treat these features and on adoption of their replacements.
