Changed

  • Generic MCP tool discovery. Register remote tools through MCP_ENABLED;
    MCP is the protocol/server boundary, not the NL2SQL toolset. The orchestrator
    discovers the server's exposed tools without initializing SQL dependencies.
    MCP_AUTH_RESOURCE_SCOPE=api://<MCP API client ID>/.default selects
    request-scoped managed-identity bearer authentication, refreshed before
    expiry without API-key fallback. External API-key MCP remains supported
    when no resource scope is configured. Accept streamable-http and JSON
    trusted-host arrays.
  • Invocation-scoped MCP refresh. Refresh MCP enablement, connection and
    authentication settings per native invocation, including activation after
    identity setup and resumed workflows. Other capability redeployment guards,
    native hosts/modes and SDK pins remain unchanged.
  • Structured NL2SQL results over MCP. Preserve schema-version-1 source,
    query and metadata IDs, typed columns, rows and count, with text-only JSON
    support and explicit tool errors through the official MCP client.

Removed

  • Breaking direct-SQL retirement. Remove direct NL2SQL registration,
    SQL/Fabric/DAX connectors, SQL validation/plugin/result types, SQL prompt
    and exclusive ODBC/sqlparse dependencies. No legacy SQL or GPT-RAG MCP
    fallback is provided.
    NL2SQL_ENABLED, NL2SQL_SOURCE_REGISTRY, NL2SQL_QUERY_TIMEOUT_SECONDS,
    NL2SQL_MAX_ROWS, DATASOURCES_CONTAINER, NL2SQL_STORAGE_CONTAINER,
    SEARCH_TABLES_INDEX_NAME, SEARCH_MEASURES_INDEX_NAME,
    SEARCH_QUERIES_INDEX_NAME, SEARCH_TABLES_INDEX_TOP_K and
    SEARCH_QUERIES_INDEX_TOP_K no longer configure orchestrator SQL.

Migration and recovery

  • Coordinated MCP adoption. Adopt the platform manifest's complete component
    combination and central operator guidance together. Configure MCP_ENABLED,
    MCP_APP_ENDPOINT, MCP_TRUSTED_HOSTS and the server's authentication
    settings; move SQL access and Cosmos vector metadata configuration to the MCP
    server. Applications needing NL2SQL use the server's enabled
    nl2sql.list_sources and nl2sql.query tools, not removed orchestrator keys.
  • Explicit server toolsets. Set server-side MCP_TOOLSETS to ["nl2sql"]
    only for applications needing SQL. The default [] keeps an authenticated
    MCP server with no tools and no NL2SQL dependency initialization. Keep
    application-specific toolsets and resources in the application definition,
    separate from the reusable foundation. The orchestrator's generic
    enablement, endpoint, scope, transport and discovery contract is unchanged.
  • Complete-combination rollback. Preserve the prior compatible platform
    manifest, all component pins, configuration, immutable image digests and
    original state. Restore that complete combination, not only the orchestrator
    or a mix of old direct-SQL settings and the new MCP server. The preceding
    orchestrator source release is immutable v6.0.0
    (8cff5be48d166e3270f874374bd343e7899073ec); it is not proof of the prior
    deployed platform pin. No data migration or rollback automation is added.

Validation

  • Focused consumer contracts. Maintained MCP client, native tool and native
    runtime tests cover official in-process MCP discovery/results, scoped bearer
    authentication and refresh, cleanup, trusted hosts and invocation-time
    activation. Release adoption also requires the actual main-target PR's
    required checks and the coordinated manifest's exact integration evidence.
  • Source-only release scope. No Azure deployment, live model call, package
    or image publication, deployed identity/RBAC, private-network or complete
    application-combination validation is claimed by this component release.

Release evidence

  • Main/tag commit: b89684b67f991b337e3519620210a6469622fc29; its tree exactly matches validated candidate 0c9fa9d5edf189cd85ba353257a89de0e7823e5a.
  • Release PR #433 passed all required checks: block-pr, tests, frontend build, and quality-gate. Pipeline run 41384913631 completed successfully.
  • Focused MCP client/native tools/native runtime batch: 89 passed. Release identity/history checks and engineering asset validation passed; all 75 external Action references remain pinned to full commit SHAs.
  • This is a source-only consumer release. Coordinated platform manifest pins and central operator documentation remain the umbrella release's adoption authority. No package, image or deployment is published here.
