+Telegram MCP Server
+
+The server uses FastMCP to expose Telegram functionality in a standardized way,
+with each tool implemented as a decorated function. This allows Claude to:
+1. Search contacts and chats
+2. Retrieve message history with optional context
+3. Send messages to individuals or groups
+
+The server connects to the local SQLite database maintained by the Telegram Bridge,
+and also communicates with the Bridge's HTTP API for sending messages.

+This module implements data models and functions for retrieving and sending
+Telegram messages, managing chats, and working with contacts. 
+
+The module connects to a SQLite database that stores all Telegram messages and chat data,
+which is maintained by the Telegram Bridge. It also provides an HTTP client for sending
+messages via the Bridge's API endpoint.
+
+Main features:
+- Data models for messages, chats, contacts, and message context
+- Database access functions for retrieving messages, chats, and contacts
+- HTTP client for sending messages through the Telegram Bridge
+- Helper functions for displaying formatted messages and chats
+
+All database operations use parameterized queries to prevent SQL injection.
