From 0abed4dfd63a4551b317be05b9aae64bd2689c9d Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Wed, 28 Jan 2026 07:14:43 +0530 Subject: [PATCH] Refactor Telegram MCP tools to utilize 'big-integer' library for consistent large integer handling - Replaced instances of BigInt with the 'big-integer' library across multiple Telegram tools, ensuring uniformity in handling large integers. - Updated type casting for input entities and user IDs to improve type safety and maintainability. - Enhanced overall code clarity by standardizing import statements and ensuring consistent use of type casting practices. These changes strengthen the reliability and consistency of the Telegram MCP tools, facilitating better integration with the Telegram API. --- src/lib/mcp/telegram/tools/addContact.ts | 3 +- src/lib/mcp/telegram/tools/blockUser.ts | 2 +- src/lib/mcp/telegram/tools/createPoll.ts | 5 +- src/lib/mcp/telegram/tools/deleteContact.ts | 2 +- .../mcp/telegram/tools/deleteProfilePhoto.ts | 3 +- src/lib/mcp/telegram/tools/exportContacts.ts | 3 +- src/lib/mcp/telegram/tools/getBotInfo.ts | 2 +- src/lib/mcp/telegram/tools/getContactIds.ts | 3 +- src/lib/mcp/telegram/tools/getGifSearch.ts | 50 +++++++++++++++++-- .../mcp/telegram/tools/getPinnedMessages.ts | 3 +- .../mcp/telegram/tools/getRecentActions.ts | 5 +- src/lib/mcp/telegram/tools/getStickerSets.ts | 3 +- src/lib/mcp/telegram/tools/getUserPhotos.ts | 5 +- src/lib/mcp/telegram/tools/getUserStatus.ts | 2 +- src/lib/mcp/telegram/tools/importContacts.ts | 3 +- src/lib/mcp/telegram/tools/listContacts.ts | 3 +- src/lib/mcp/telegram/tools/unblockUser.ts | 2 +- 17 files changed, 76 insertions(+), 23 deletions(-) diff --git a/src/lib/mcp/telegram/tools/addContact.ts b/src/lib/mcp/telegram/tools/addContact.ts index 122b42bad..529ac9b62 100644 --- a/src/lib/mcp/telegram/tools/addContact.ts +++ b/src/lib/mcp/telegram/tools/addContact.ts @@ -3,6 +3,7 @@ import type { TelegramMCPContext } from '../types';
