WalkthroughThe change adds transport-neutral OKP product/version filters to query APIs. RAG retrieval can use RHOKP MCP when available and fall back to Solr. MCP results are normalized into shared RAG models, and endpoint wiring and tests cover the new flow. ChangesOKP request contract and configuration

Merge Risk: 🟡 Moderate · up to Deployments without OKP enabled can incur periodic request delays while probing an unused MCP endpoint. Correct the probe ordering before merge; the documentation should also be aligned with the single-request retrieval behavior. 🚥 Pre-merge checks | ✅ 7✅ Passed checks (7 passed)

…ring Adds an interchangeable MCP transport for OKP RAG retrieval alongside the existing OGX/Solr vector_io path, forked at build_rag_context by okp_rag_mcp_enabled(). - OkpMcpConfiguration (rag.okp.mcp): enabled flag, url, tool_name, max_chunks, timeout, authorization_headers, plus structured product/product_version filters that mirror the Solr transport's chunk_filter_query filtering. - OkpMcpRetriever + call_okp_search: single direct MCP search-tool call over streamable HTTP (pydantic-ai MCPToolset), mapping results to the backend-neutral RAGChunk/ReferencedDocument contract shared with the Solr path; product/product_version passed as structured tool args when set. - Regenerated OpenAPI schema for the new config fields. - Unit tests for the client, provider, config model, configuration fork, vector_search fork, and enrichment. The server-side product/version filtering support (mimcp search tool) is a separate change in the RHOKP repository. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Introduce OkpFilter/OkpProductFilter, a backend-neutral query-time RAG
filter (product selections, each scoping its own exact-match versions),
decoupled from Solr fq and the OGX {type,key,value} grammar so the public
interface survives the OGX->pydantic-ai migration.
- models.common.query: OkpProductFilter + OkpFilter (nested array shape).
- QueryRequest / OpenAI responses request: new optional `okp` field.
- OkpMcpRetriever.fetch: accept `okp`, fan out one MCP search per
(product, version) pair, then merge/dedup/sort/cap results.
WIP: `okp` is not yet threaded through vector_search.build_rag_context ->
_fetch_okp_rag_mcp/_fetch_okp_rag, so the field is accepted but not yet
consumed. Endpoint wiring, Solr-side translation, tests, and rag_guide
docs still pending.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Thread the request-level `okp` filter from all three inference entry points (query, streaming_query, responses) through build_rag_context to whichever OKP transport is active, completing the query-time filtering started in the previous commit. - vector_search: build_rag_context/_fetch_okp_rag_mcp/_fetch_okp_rag now accept `okp`; _okp_filter_to_structured translates it to an OGX eq/in/and/or filter for the legacy Solr path (AND-combined with any structured solr filter), so `okp` is not a no-op on the default transport. - MCP transport: OkpMcpRetriever.fetch fans out one search per (product, version), then merges/dedups/score-sorts/caps; a query-time filter overrides the launch-time config defaults. - Regenerate OpenAPI schema (OkpFilter/OkpProductFilter components) and document `okp` in rag_guide.md as the backend-neutral, preferred filter. - Unit tests: model validation, Solr translation, param merge, provider fan-out/override/merge/partial-failure, and transport forwarding. Verified: ruff, black, pydocstyle, pylint, pyright, and mypy clean on changed sources; affected unit suites pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…ansport probe
Replace the launch-time MCP config flag with automatic per-request transport
selection. The OKP config reverts to its pre-MCP shape (rag.okp.{rhokp_url,
offline, ...}) with no mcp block; the MCP endpoint is always derived as
rhokp_url/mcp. Old configs keep working unchanged.
Transport selection:
- Launch: always wire the Solr vector_io provider (no synthesis-time coupling
to RHOKP; enrich_okp_mcp and the synthesis fork are removed).
- Query: prefer the MCP transport whenever okp_mcp_available() is True, falling
back to Solr when MCP is unavailable or hard-fails for the request.
- Fail-forward: the probe result is TTL-cached (not sticky) so an upgraded
RHOKP is adopted without restarting LCORE.
Product/version filtering is query-time only via the request `okp` filter; the
launch-time product/product_version config is dropped. OkpMcpConfiguration and
RH_SERVER_OKP_MCP_DEFAULT_URL are removed; OpenAPI schema regenerated.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The RHOKP MCP `search` tool now accepts a structured, Solr-fq-analogous product filter and builds the query-side filter itself, so the OKP MCP retriever no longer fans out one call per (product, version) combo. - _client.call_okp_search: replace scalar product/product_version with an optional structured `products` arg, forwarded verbatim and omitted when None/empty. - _provider: drop _resolve_search_combos; add _okp_products_arg to translate the transport-neutral OkpFilter into the structured products list, and issue a single search call, raising OkpMcpUnavailableError on any failure so the caller falls back to the Solr transport. - Rewrite unit tests for the single-call structured-filter contract. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The OKP product identifier is red_hat_enterprise_linux, not rhel. Correct the OkpProductFilter/OkpFilter examples and the tests exercising the slug, and regenerate the affected openapi.json examples from the model. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

In `@docs/user_doc/rag_guide.md`:
- Around line 398-422: The RAG guide incorrectly says the MCP transport issues
one search per product/version pair. Update the paragraph describing
OkpMcpRetriever to state that it sends one MCP search request containing the
complete products list, with product/version filtering performed server-side,
while preserving the documented deduplication and rag.okp.max_chunks cap on the
combined response.
In `@src/utils/vector_search.py`:
- Line 775: Update _fetch_okp to return empty RAG results immediately when
configuration.okp_inline_enabled is false, before calling okp_mcp_available().
Preserve the existing MCP probe, fallback, and transport behavior when OKP is
enabled.

| The `solr` field and its `fq`/structured filters are Solr-specific. For a | ||
| backend-neutral, forward-compatible product/version filter that works across | ||
| **both** OKP transports (the RHOKP MCP server and the legacy Solr path), use the | ||
| request field **`okp`** instead. It carries a list of product selections, each | ||
| scoping its own exact-match versions (no wildcards), so an invalid | ||
| product/version pairing is not representable. Product/version filtering is | ||
| query-time only; there is no launch-time product/version configuration. | ||
|
|
||
| ```json | ||
| { | ||
| "query": "How do I configure routes?", | ||
| "okp": { | ||
| "products": [ | ||
| { "product": "openshift_container_platform", "versions": ["4.16", "4.17"] } | ||
| ] | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| Multiple products are OR'd; a product with no `versions` matches regardless of | ||
| version. On the MCP transport each (product, version) pair becomes one search and | ||
| the results are merged, deduplicated, and capped at `rag.okp.max_chunks`. Prefer | ||
| `okp` over `solr` for product/version filtering; `solr` remains for Solr-specific | ||
| needs during the OGX/Solr transition. | ||

Correct the MCP retrieval semantics. OkpMcpRetriever sends one MCP search request with the complete structured products list. It does not run one search for each product/version pair. Update this paragraph to describe the single request and server-side product/version filtering. Keep the documented deduplication and rag.okp.max_chunks cap for the combined response.

Gate the MCP probe on OKP being enabled.
_fetch_okp calls await okp_mcp_available() before checking whether OKP RAG is configured at all. _fetch_okp_rag_mcp and _fetch_okp_rag both check configuration.okp_inline_enabled / _is_solr_enabled(), but only after this probe already ran.
For a deployment that does not list "okp" in rag.retrieval.inline.sources, build_rag_context still probes okp_mcp_endpoint_url() (defaults to http://localhost:8081/mcp) on every request once the TTL cache expires, with a 5-second timeout (OKP_MCP_PROBE_TIMEOUT_SECONDS). This repeats every OKP_MCP_PROBE_TTL_SECONDS (60s), indefinitely, on /v1/query, /v1/streaming_query, and /v1/responses.
The test suite needed a new autouse fixture in tests/unit/utils/test_vector_search.py to stop unrelated (non-OKP) tests from hitting a live probe through build_rag_context — this confirms the probe fires unconditionally.
Hoist the enablement check to the top of _fetch_okp, before the probe.

This is a big PR. Are we planning on breaking it down to smaller pieces (with this PR serving as the "demo") or have we been merging big PRs like this typically?

Summary
RHOKP RAG context used to enrich LCORE responses currently comes from direct calls to the Solr API hosted in RHOKP.
This PR adds conditional support for fetching that same context via RHOKP's upcoming MCP server. The support is conditional in the following sense: when LCORE is configured to fetch context from RHOKP, it will attempt MCP, and fall back to Solr if MCP is not available. In this way, LCORE has support for RHOKP RAG regardless of the version of RHOKP currently deployed. The conditional support also allows existing LCORE configuration to work with RHOKP before and after the release of the MCP server.
The plan discussed with the LCORE team is that the Solr provider (in lightspeed-providers) will be deprecated and eventually removed. The migration to Pydantic AI will not include Solr, so the migration timeline is, in a way, the same as the timeline for Solr provider removal.
