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).
