- implement server-side allowlist via CLI positional roots (fallback)\n- implement client MCP Roots override semantics (replace server roots when available)\n- add realpath + in-root validation, traversal/glob rejection, extension and size checks\n- make write path default to <first_root>/downloads when file_path is omitted\n- reintroduce upload_file tool with the same path security model\n- update README with security model and usage\n- add tests for root resolution, replacement semantics, traversal checks, and default write path\n- add pytest and pytest-asyncio to dev dependencies
archive_chat and unarchive_chat were using ToggleDialogPinRequest which
pins/unpins dialogs instead of archiving them. Replace with
folders.EditPeerFoldersRequest using folder_id=1 (Archive) and
folder_id=0 (Main) which is the correct API for moving chats to/from
the Archive folder.
- Changed phone parameter to Optional[str] = None
- Added separate username parameter (Optional[str] = None)
- Improved function signature clarity - username is now explicit parameter
- Updated validation logic to check for either phone or username
- Maintains backward compatibility with phone-based contacts
- Better API design - no longer need to pass username via phone parameter
- Modified add_contact function to support username-based contact addition
- If phone parameter is empty or starts with @, function resolves username first
- Uses contacts.AddContactRequest API for username-based contacts
- Maintains backward compatibility with phone-based contact addition
- Allows adding contacts as done in Telegram UI when searching by username
Add new MCP tools to manage Telegram dialog folders (filters):
- list_folders: get all folders with IDs, names, emoji
- get_folder: get folder details including all included chats
- create_folder: create new folder with filters and chat list
- add_chat_to_folder: add chat to existing folder (idempotent)
- remove_chat_from_folder: remove chat from folder (idempotent)
- delete_folder: delete folder (chats preserved)
- reorder_folders: change folder order
Handles Telegram API specifics:
- TextWithEntities for folder titles
- Max 10 folders limit
- System folder protection (ID < 2)
- title_noanimate and color attributes

The individual line suggestions created invalid Python when applied
separately. Combined the ternary expression properly.

Previously list_chats only checked dialog.unread_count, missing chats
that were manually marked as unread via Telegram's "mark as unread" feature.
Now also checks dialog.dialog.unread_mark flag:
- unread_count > 0: shows "Unread: N"
- unread_mark = True: shows "Unread: marked"
This matches the behavior of Telegram's "Unread" folder filter.

Add three new tools for managing Telegram drafts:
- save_draft: Save a draft message to any chat/channel
- get_drafts: List all drafts across all chats
- clear_draft: Clear a draft from a specific chat
Uses Telethon's SaveDraftRequest and GetAllDraftsRequest APIs.
Drafts appear in Telegram's input field for review before sending.

Add three new MCP tools for handling Telegram message reactions:
- send_reaction: Send emoji reaction to a message
- remove_reaction: Remove your reaction from a message
- get_message_reactions: Get list of reactions on a message
All tools include proper ToolAnnotations and follow existing code patterns.
Add human-readable title annotations to all MCP tools to help clients
display tool names in a user-friendly format.
Changes:
- Added title annotation to all 78 tools (e.g., "Get Chats", "Send Message")
- Formatted with Black for code style consistency
This improves the user experience when MCP clients display tool lists.

Add new list_topics() MCP tool to retrieve forum topics from Telegram
supergroups with forum feature enabled.
Features:
- Validates chat is a supergroup with forum enabled
- Supports pagination via offset_topic parameter
- Supports search filtering via search_query parameter
- Returns comprehensive topic metadata:
* Topic ID and title
* Total messages and unread count
* Status flags (closed, hidden)
* Last activity timestamp
- Proper error handling and logging
Documentation:
- Added list_topics to README Messaging tools list
- Added complete code example with implementation
- Added example output showing typical usage
Uses Telethon's GetForumTopicsRequest API for reliable forum topic
retrieval from supergroups.
- stream search results via `client.iter_messages()` and apply date bounds in-code so we collect up to `limit` matches
- use server-side iteration for date-only queries with inclusive upper bounds to avoid over-fetching
- keep the existing `get_messages()` fast path when no filters are provided
- Add python-json-logger dependency.
- Configure file handler to use JsonFormatter for structured logging.
- Keep console handler with the existing text format.
- Refactor log_and_format_error to log a dictionary with structured error data.
Adds a new `@validate_id` decorator to validate `chat_id` and `user_id` parameters in `main.py`.
This decorator ensures that all IDs passed to functions are in a valid format before making RPC calls to the Telegram API. It handles:
- Integer IDs (positive and negative)
- String representations of integer IDs
- Usernames (e.g., "@username")
- Lists of IDs
Key changes:
- Created a `validate_id` decorator in `main.py`.
- Applied the decorator to all functions that accept `chat_id`, `user_id`, or similar parameters.
- Updated the central `log_and_format_error` function to handle custom validation error messages and a specific `VALIDATION-001` error code for logging.
- Added a new test suite (`test_validation.py`) with comprehensive tests for the decorator.
- Updated `README.md` and `session_string_generator.py` with documentation about the new validation.
Updated message formatting in various functions to include details about replies. When a message is a reply, it now shows the ID of the original message and the sender's name, improving context for users.
