NuklearRabbitandClaude Sonnet 5 727c19a779 M9: MCP Hub locale/correlation propagation, real Hub health check, fix stale test image
Fixed two concrete gaps in the MCP knowledge-search endpoint: no locale field
existed at all (now nl-BE/en-GB/fr-BE, wired to the knowledge provider's
existing language param), and the correlation ID was always freshly minted,
ignoring any inbound X-Correlation-Id header. Added a shared dependency and
applied it to all four MCP endpoints so Fleet Ops's own audit log preserves
the Hub's real correlation ID end to end.

MCP_HUB_BASE_URL/MCP_PROVIDER_ID were declared in .env.example but never read
anywhere. Since the Hub's own registration is catalog-driven (it never needs
Fleet Ops to push a registration call), wired mcp_hub_base_url for a real Hub
reachability health check instead of an unneeded self-registration call.

Renamed Fleet Ops's own internal audit tool labels mobilityops_* -> fleet_ops_*
(mirrored in contracts/mcp-tools.json with mobilityops_* kept as deprecated
aliases); documented that the live Hub connector's own dotted tool namespace
is a separate, Hub-owned naming layer, deliberately not touched.

Automation page's MCP card now shows real evidence (last tool/client/count/
timestamp, honest no-evidence state) instead of just the registration flag.

Also fixed a real methodology gap found mid-session: compose.yaml's api
service has no bind mount, so `docker compose run --rm api` silently tests a
stale image until rebuilt. Re-ran every local gate after rebuilding; fixed one
genuinely stale test assertion and two lint line-length errors surfaced by
that rebuild. 176 tests passing, ruff clean, mypy clean (50 files).

# ITWorx MCP Hub integration
## Objective
Publish four read-only MobilityOps capabilities through the existing central ITWorx MCP Hub. MobilityOps does not host MCP transport itself.
## Provider registration
- provider ID: `mobilityops` (registered on the Hub side; the Hub's own registration is
catalog-driven — it reconciles its catalog into the gateway, Fleet Ops never pushes a
registration call)
- API base: internal Fleet Ops API URL, reached via `MCP_HUB_SERVICE_TOKEN` auth
- authentication: scoped service token (`X-Service-Token`), plus `X-Client-Id`
- mode: read-only
- **Confirmed live in production** on the ITWorx MCP Hub's own deployment (Tower), with
a real contract fix already applied there (`vehicle.get`'s wire parameter normalized to
camelCase `vehicleRef`). `docs/final-integrations/current-state-audit.md` has the full
evidence.
## Tools
The machine-readable definitions are in `contracts/mcp-tools.json`. The Hub's own live
connector (`ITWorx_MCP_Hub` repo, `connectors/mobilityops/`) publishes these under its
own dotted namespace — that naming is the Hub's to own, not Fleet Ops's:
1. `mobilityops.operations.summary`
2. `mobilityops.attention.list`
3. `mobilityops.vehicle.get`
4. `mobilityops.knowledge.search`
Fleet Ops's own internal audit trail (`AuditEvent.metadata_json.tool`, visible on
`/api/v1/audit?action=mcp_tool_request`) labels these calls `fleet_ops_get_operations_summary`,
`fleet_ops_list_attention_vehicles`, `fleet_ops_get_vehicle_details`,
`fleet_ops_search_knowledge` — a separate, Fleet-Ops-owned naming layer for its own audit
log, not the wire-level MCP tool name a client calls.
`search-knowledge` accepts a `locale` field (`nl-BE` | `en-GB` | `fr-BE`, default
`en-GB`) that is passed straight through to the active knowledge provider.
## Correlation ID
The inbound `X-Correlation-Id` header (set by the Hub, itself either forwarding the
MCP client's ID or minting one) is preserved through Fleet Ops's own handling and audit
log; Fleet Ops only mints a fresh correlation ID when none is supplied or the supplied
value isn't a valid UUID. See `get_correlation_id` in
`backend/app/api/routers/mcp_integrations.py`.
## Routing
Operational tools:
```text
AI client -> MCP Hub -> MobilityOps provider API
```
Knowledge tool:
Preferred:
```text
AI client -> MCP Hub -> RAGcore workspace mobilityops
```
If the Hub requires a single provider boundary, route through a narrow MobilityOps knowledge façade that calls RAGcore. Do not duplicate retrieval logic.
## Restrictions
Do not expose:
- generic SQL;
- arbitrary URL fetching;
- arbitrary shell commands;
- return registration;
- customer merge;
- booking or vehicle mutation;
- secrets or raw service configuration.
## Audit
The Hub owns central tool-call audit. MobilityOps also records service requests that reach its provider APIs with tool name, correlation ID, client/service identity and result status.
