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

Repository: this checkout of shiori-mcp
Implemented tool surface:
- shiori_health_check()
- shiori_list_bookmarks(limit, offset)
- shiori_search_bookmarks(query, tag, limit, offset)
- shiori_get_bookmark(bookmark_id)
- shiori_get_bookmark_by_url(url)
- shiori_add_bookmark(url, title, excerpt, tags, public, create_archive)
- shiori_update_bookmark(bookmark_json)
- shiori_update_bookmark_fields(bookmark_id, title, excerpt, public, tags, create_archive)
- shiori_delete_bookmark(bookmark_id)
- shiori_delete_bookmarks(ids_json)
- shiori_list_tags()
- shiori_rename_tag(tag_id, name)
- shiori_list_accounts()

Implementation notes:
- Python 3.11 package using mcp.server.fastmcp.FastMCP.
- All tool params use typing.Annotated + pydantic.Field descriptions.
- Auth supports either SHIORI_SESSION_ID or login via SHIORI_USERNAME and SHIORI_PASSWORD.
- Client uses Shiori's documented legacy `/api/*` API with X-Session-Id headers. Shiori's `docs/API.md` currently documents these endpoints; `docs/APIv1.md` states the new API is still in development and self-documented only on a running instance, so this server intentionally targets the documented legacy API for compatibility.
- Tags are normalised from comma-separated names into Shiori's required [{"name": ...}] format for bookmark creation.
- Client-side search and get-by-id wrap Shiori's documented /api/bookmarks endpoint.
- Authenticated writes are mocked with respx; public live validation checks Shiori API docs and repo pages without credentials.
