You are validating a new wallabag MCP server implementation before publication.

Repository: this checkout of wallabag-mcp
Implemented tool surface:
- wallabag_health_check()
- wallabag_list_entries(page, per_page, sort, order, archived, starred, unread, domain_name, tags)
- wallabag_get_entry(entry_id, include_content)
- wallabag_add_entry(url, title, tags, archive, starred)
- wallabag_update_entry(entry_id, title, url, archived, starred, tags)
- wallabag_archive_entry(entry_id)
- wallabag_unarchive_entry(entry_id)
- wallabag_star_entry(entry_id)
- wallabag_unstar_entry(entry_id)
- wallabag_reload_entry(entry_id)
- wallabag_delete_entry(entry_id)
- wallabag_list_tags()
- wallabag_add_tags_to_entry(entry_id, tags)
- wallabag_delete_tag(tag_id)
- wallabag_list_annotations(entry_id)
- wallabag_create_annotation(entry_id, text, quote, ranges_json)
- wallabag_delete_annotation(annotation_id)

Implementation notes:
- Python 3.11 package using mcp.server.fastmcp.FastMCP.
- All tool params use typing.Annotated + pydantic.Field descriptions.
- Authentication supports either WALLABAG_ACCESS_TOKEN or password grant via WALLABAG_CLIENT_ID, WALLABAG_CLIENT_SECRET, WALLABAG_USERNAME, WALLABAG_PASSWORD.
- Client uses Bearer token authorization and normalises wallabag HAL _embedded.items pagination responses.
- Mutation endpoints normalise empty/non-JSON responses and refetch when needed.
- Tests passing locally: ruff check, pytest, MCP stdio tools/list schema validation.
- Live validation checks public wallabag API docs and hosted API documentation pages without account credentials.
- Authenticated writes are not run against a public instance; HTTP behaviours are mocked with respx.
