A mechanical prettier --write over server/src, server/tests, server/scripts and shared/src with the workspaces' .prettierrc; nothing but layout and import order changes, and every file keeps the same set of imports. shared is formatted throughout and its format baseline is empty. The server baseline keeps the 35 files that Prettier would grow past their lint:size limit (they need a split first, which is not a formatting change), and the generated entity files stay as their generator writes them.

// The seam that lets a per-session MCP server carry tools contributed by installed
|
|
// plugins, without src/nest/mcp-transport/ gaining an edge to the plugin runtime —
|
|
// the same module cycle trip-warnings.mcp.ts documents. Sibling of
|
|
// plugin-event-sink.ts and plugin-user-lifecycle.ts; the plugins layer registers
|
|
// the source at bootstrap and clears it on shutdown.

/**
|
|
* PULL rather than push, unlike setPluginEventSink: the answer depends on the
|
|
* session's ctx, so there is nothing a push could carry ahead of time, and
|
|
* reading it on every attach means activating or uninstalling a plugin takes
|
|
* effect on the next session with nothing to invalidate. That is the argument
|
|
* channel-registry.ts already makes for setPluginChannelSource.
|
|
*
|
|
* Unlike every sink beside it this one returns a value on the request path. An
|
|
* unset source is not an error: it means "no plugin tools", which is the right
|
|
* answer for any app built without the plugins runtime, and for every test that
|
|
* never registers one.
|
|
*
|
|
* Deliberately NOT wrapped in try/catch here. nest-mcp's attach() contains a
|
|
* throwing source per its own contract and logs which one failed; catching it
|
|
* again on the way out would swallow that diagnostic and report the same
|
|
* degraded surface less usefully.
