What
sdkMcpServerManifests is how the Agent SDK tells Claude Code about MCP servers when it starts. Claude Code's own description of this field has changed. It now says a manifest is reported as not_honoured when the remote session is not an interactive Cowork chat started from claude.ai.
Before, the description said manifests were not used when manifests, or remote manifests, were switched off in this copy of Claude Code. Only the description changed. The check Claude Code runs may not have changed.
Why
If you build on the SDK, this describes a narrower set of remote sessions where manifests are used.
