/**
|
||
* Lakehouse MCP Server — bridges local LLMs to the data substrate.
|
||
*
|
||
* Tools:
|
||
* - search_workers: hybrid SQL+vector (the core fix)
|
||
* - query_sql: analytical SQL on any dataset
|
||
* - match_contract: find workers for a job order
|
||
* - get_worker: single worker by ID
|
||
* - rag_question: full RAG pipeline
|
||
* - log_success: record what worked → playbook DB
|
||
* - get_playbooks: retrieve past successes
|
||
* - swap_profile: hot-swap model + data context
|
||
* - vram_status: GPU introspection

<strong>How to verify:</strong> Every number on this page was generated live by the server responding to your browser request.
|

Hit refresh — the queries run again. These are not cached or pre-computed. The SQL tests execute on ${totalRows.toLocaleString()} real rows.
|
||
The hybrid search finds real workers with real names, skills, and certifications — every result marked <code>sql_verified: true</code>.
