Review gate on #7720 (two regressions reproduced against master with the
installed Agent):
1. Deleting a profile's last MCP server left ADOPTED tools callable after
/reload-mcp. The scoped teardown only stops connections the profile owns,
and the Agent's discover_mcp_tools() returns before its reconcile step
when the profile's config has no server, so an adopted shared connection
was never judged against the config. /reload-mcp now calls
register_mcp_servers({}) under the profile's scope before rediscovery:
the Agent's overlay heal detaches only this profile's overlay for servers
its config no longer has; the owner's connection keeps running (master's
wildcard shutdown stopped the owner too).
2. Portable plugin MCP servers are merged by the Agent at runtime and never
appear in the profile's raw ``mcp_servers``; the registry fallback
required a config entry and dropped every plugin tool from
/api/mcp/tools and the Notes inventory. The profile's own registry slot
(registry_tool_owned_by_view) is the isolation check; the config is not
an allowlist any more.
Tests (red before, green after): agent-free unit tests for both (the fake
agent now models the overlay heal and discovery's empty-config early
return), and a real-Agent integration test for the adopted-then-deleted
case (owner connection survives, adopter slot emptied, "Removed" reported).

Review follow-up on #7720 (Greptile P2): the external Notes drawer reads the
same profile-bound MCP inventory as the MCP panel but dropped the
``runtime_scope`` label, so a profile whose runtime scope could not be
confirmed rendered its note sources as inactive/configured with no
explanation. ``/api/notes/sources`` now returns ``runtime_scope`` and the
drawer shows the existing ``mcp_runtime_scope_unavailable`` notice (same key,
no new locale strings) when it is ``unavailable``.
Tests: the skewed-routing unit test now also asserts the notes response
carries ``runtime_scope: "unavailable"`` with its sources inactive.
docs/troubleshooting.md mentions the drawer next to the panel.

Two profiles configuring a same-named MCP server shared one connection and
the MCP settings panel showed another profile's runtime ("Active, N tools"
next to an empty inventory); /reload-mcp stopped every profile's servers and
rediscovered from the process-default config.
- api.profiles._set_hermes_home() is the single writer of the process-profile
home: it records get_process_profile_home() and hands it to Hermes Agent's
hermes_constants.pin_process_hermes_home when available, at startup and on
switch_profile(process_wide=True), so the per-turn HERMES_HOME mirror no
longer makes every turn look like the process profile (bare-name,
cross-profile MCP keys) and the anchor cannot drift from HERMES_HOME.
- Run get_mcp_status/registry reads and /reload-mcp inside
api.mcp_runtime.mcp_runtime_scope(): request profile's Hermes-home override
and secret scope (root included), no os.environ mutation, restored on exit.
- One ledger predicate, ledger_key_serves_view() (owned via
_server_scope_keys/key scope, or adopted via _server_tool_scopes), is shared
by status, inventory and the reload summary. The Agent's launch-profile view
is process-wide and name-indexed, so filter_runtime_status_to_view()
rebuilds connected/tools/status/error from the entries serving the profile:
the root profile never shows a routed profile's connection (nor lets its own
parked failed-spawn task borrow a routed profile's live same-named one).
- Inventory lists only tools in the profile's own registry slot for servers it
configures; responses carry runtime_scope.
- Fail closed when the agent's routing does not match the resolved profile:
hide runtime data (runtime_scope "unavailable", shown as a notice in the MCP
panel, 14 locales) and refuse /reload-mcp.
- /reload-mcp shuts down only the profile's own ledger names (parked
included), drops its own connect cooldown/error entries so a failed spawn is
retried (the wildcard cleared every cooldown; a scoped shutdown only clears
the live keys it tears down), rediscovers under the profile's home and
counts live connections only. The bare wildcard remains for agents without
profile-scoped MCP.
- Signature introspection is centralized (accepts_keywords) and falls back to
the bare call instead of blanking every status; ledger key helpers resolve
to the Agent's tools.mcp_tool_scope when present; tools.mcp_tool is
resolved by full name so stubbed agents still work.
- ARCHITECTURE.md §4.10 and docs/troubleshooting.md document the boundary.
- Tests: agent-free contract (models adoption, parked tasks, cooldowns and the
process-wide root view) and real-Agent integration (fake stdio MCP server,
skips without hermes-agent + mcp SDK).
