📝 WalkthroughWalkthroughThe MCP documentation flow now exports the documented modules, inspects the complete FastMCP surface in a child process, renders availability requirements, and fails when generators or documentation includes are invalid. ChangesMCP documentation generation

Pull request overview
Updates the airbyte.mcp package exports so pdoc can generate documentation pages for all intended MCP modules (notably interactive and prompts), aligning the package’s public surface with the MCP module layout.
Changes:
- Export
interactiveandpromptsfromairbyte.mcpby importing them in__init__.py. - Extend
__all__to includeinteractiveandpromptsso documentation tooling surfaces these modules.
💡 Add a code-review agent skill or configure MCP servers for context-aware, tailored reviews. Learn more in the docs.

so formatting an out-of-root target cannot raise ValueError; use a defensive
representation or fallback path while still appending the missing include and
allowing the existing unresolved-includes RuntimeError flow to run.

Summary
Two docs defects, both reproducible on a clean
mainwithuv run poe docs-generate:1.
airbyte.mcp.__all__omitted submodules, so pdoc emitted no page forairbyte.mcp.interactiveorairbyte.mcp.prompts(both 404 on the published site). Addedinteractiveandprompts— plus a test that__all__covers every non-underscore submodule found bypkgutil.iter_modules, so a new module can't silently go undocumented again.That test also surfaced a scoping question, since pdoc renders exactly the submodules named in
__all__:serverandhttp_mainare process entry points whose public surface is amain()nobody calls directly, and their connectivity/env docs are already the canonical text inairbyte.mcp's own docstring. So both are now out of__all__(and out of the docs), with the coverage test carrying an explicit, asserted exception set rather than a silent gap:Note this drops the pre-existing
airbyte.mcp.serverpage. Both modules keep their names and import paths, sofrom airbyte.mcp.server import appand theairbyte-mcp/airbyte-mcp-httpentry points are unaffected; renaming them to_server/_http_main(which would make the exclusion self-evident and drop the exception set) is left as a follow-up.2.
docs-generateprintedCannot include '.../local.md'and exited 0.scripts/generate_mcp_markdown.pydocumented whateverfastmcp inspectreturned, andinspectruns the tool-filter middleware — so a default pass only saw 40 of 55 tools.local's tools are annotatedrequiresClientFilesystem=Trueand hidden unlesstrusted_executionis on;interactive's are annotatedinteractive-uiand hidden unless the client declares theio.modelcontextprotocol/uiextension. Those two gates can't both be open in one pass —trusted_execution_filterforce-disables itself whenever an HTTP request context is active, and the UI extension declaration can only arrive through one. So the generator now inspects twice and merges:The inspect runs in a child process (
--emit-inspect-jsonself-reinvocation) so the docs build itself never runs with trusted execution enabled and never imports the MCP server. All the gate names come from the installed packages (MCP_TRUSTED_EXECUTION_ENV_VAR,UI_EXTENSION_ID,DEFAULT_EXTENSIONS_HEADER,ANNOTATION_*), not string literals.Also in this PR:
_regenerate_mcp_markdown()no longer swallows generator failures into a warning, and a new_validate_includes()scansairbyte/**/*.pyfor.. include::targets and raises listing every missing one, before pdoc runs.airbyte/mcp/interactivegot the include directive it never had (../../../docs/mcp-generated/interactive.md— one level deeper since it's a package).**Availability:** requires trusted execution (AIRBYTE_MCP_TRUSTED_EXECUTION=1, stdio transport only); never available over HTTP.(the optional half of the issue — done, not skipped).Generated output stays git-ignored; nothing under
