Error Messages/Logs

Steps to Reproduce

1. Install the official Telegram plugin for Claude Code
2. Configure bot token via /telegram:configure <token>
3. Pair a Telegram user via /telegram:access pair <code> and set policy to allowlist
4. Confirm the MCP server is running (ps aux | grep telegram) and polling Telegram (getUpdates returns 409 conflict)
5. Send a DM to the bot from the allowlisted Telegram account
6. Message never appears in the Claude Code session

Expected: Inbound Telegram message surfaces in the conversation via notifications/claude/channel

Actual: Nothing happens. No error, no message.

Diagnosis:

• Bot token is valid (getMe succeeds)
• Server is polling (getUpdates returns 409, confirming active long-poll)
• Messages pass the access gate (killing the server and calling getUpdates returns empty — server consumed the

updates)

• mcp.notification({ method: 'notifications/claude/channel', ... }) is called without error (confirmed by adding

.then() debug log)

• MCP stdio transport (unix sockets) is connected between server and Claude Code
• The break is on the Claude Code client side — it does not surface notifications/claude/channel from the MCP server

Environment:

• Claude Code 2.1.81
• macOS (Darwin 25.4.0)
• MCP SDK 1.27.1
• Plugin: claude-plugins-official/telegram/0.0.1
• bun runtime
