- Add openWorldHint=True to all 63+ @mcp.tool decorators - Add readOnlyHint=True to read-only operations (get/list/search/export functions) - Add destructiveHint=True to state-changing operations (send/create/delete/edit functions) - Add idempotentHint=True to safely repeatable operations (block/unblock/pin/unpin/ban/unban/etc.) - Fix syntax errors: openWorldHint(True) → openWorldHint=True - Remove incorrect idempotentHint from non-idempotent operations (send_file, press_inline_button, import_contacts) These annotations help MCP clients understand tool behavior: - readOnlyHint: tool doesn't modify environment - destructiveHint: tool performs destructive updates - idempotentHint: repeated calls with same args have no additional effect - openWorldHint: tool interacts with external entities (Telegram API) Improves tool discoverability and helps AI agents make better decisions about tool usage.

Fixes chigwell#37 The mcp package was locked at version 1.6.0 which does not include the ToolAnnotations type. This caused the server to fail on startup with: ImportError: cannot import name 'ToolAnnotations' from 'mcp.types' Updated mcp from 1.6.0 to 1.22.0 which includes ToolAnnotations and is compatible with the code added in PR chigwell#34. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
