Search for a specific chat by name, username, or ID.
AI agents call telegram_find_chat to retrieve information from Telegram MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about existing chats without creating, modifying, deleting, or executing any actions. Searching and querying are canonical Read operations. The severity is low because discovering chat metadata poses minimal risk—the harm from misuse is limited to information disclosure of chat identities, which is typically non-sensitive metadata.
From the tool's definition Tool performs a search operation to locate a chat by name, username, or ID. The description explicitly states it 'Search[es] for a specific chat' with no indication of modification, deletion, or execution capabilities. It retrieves chat metadata only.
