Best for
  • Users with large note libraries where substring search is insufficient.
  • Users switching between multiple MCP clients (Claude Desktop, Claude Code, Cursor, Codex, Gemini, etc.).
  • Users who want to query notes without opening Bear.
  • Users needing library-wide tag management.
  • Users concerned about supply-chain hygiene and privacy.
  • Developers who want to integrate Telegram into MCP clients like Claude
  • Automation scenarios that need to manage multiple Telegram accounts
  • Building custom Telegram bots or workflows
  • Scenarios that require secure file operation path restrictions
Not for
  • Users with small libraries who just want quick note integration.
  • Users unwilling to grant MCP server access to local database.
  • Users needing Windows or Linux support (macOS only).
  • Users requiring official support or guarantees (unofficial project).
  • Use cases requiring official Bot API features (this server uses a user client)
  • Non-technical users who want a fully managed solution
  • Multiple processes using the same session without lock management
Required permissions
  • Read access to Bear Notes SQLite database.
  • Write access via Bear's X-callback-URL API when Edit Mode is enabled.
  • Optional attachment of local files (max 25 MB).
  • Optional communication with AI provider when using an AI assistant (data sent to your provider).
  • Requires Telegram API ID and API Hash
  • Requires the user's Telegram session string (equivalent to account access)
  • Can send messages, media, contacts, and settings to any allowed chat
  • Can create or modify groups, channels, and chat settings
  • Can access and operate on the user's media files and contacts
Risks and side effects
  • Extension installation shows a red warning about granting access to everything on your computer, but actually only accesses Bear's database.
  • Write operations require Edit Mode and may overwrite data if revision tokens are stale.
  • Unofficial project; there may be bugs, but the codebase is small and reviewable.
  • macOS only.
  • Session string leakage could lead to account compromise
  • Sending messages may raise privacy or security concerns
  • Prompt injection: Telegram content may be maliciously crafted, so precautions are needed
  • Risk of using unofficial PyPI package name; avoid pip install telegram-mcp
  • Concurrent clients using the same session may cause AuthKeyDuplicatedError
