When the MCP stdio transport closes, the bot kept polling Telegram as
a zombie process — holding the token and causing 409 Conflict for the
next session.
- Listen for stdin end/close and SIGTERM/SIGINT -> bot.stop() + exit
- Force-exit after 2s if bot.stop() stalls on the long-poll timeout
- unref the approval-check interval so it doesn't keep us alive
Fixes#793, partial #788 (issue 3)
The bot would silently stop delivering messages after the first error:
grammy's default handler calls bot.stop() on any middleware throw, and
void bot.start() / void mcp.notification() swallow rejections with no log.
- bot.catch(): log and keep polling on handler errors
- bot.start().catch(): log when polling dies (bad token, 409, network)
- mcp.notification().catch(): log when inbound delivery to Claude fails
- process-level unhandledRejection/uncaughtException as a safety net
Fixes#756#759#761#777#809, partial #788
The bot token is a credential. Tighten perms on load so hand-written
or pre-existing .env files get locked down, and update the configure
skill to chmod after writing. No-op on Windows.
Remove the three chat bridge plugins from external_plugins/ and their
corresponding entries in marketplace.json.

Telegram messaging bridge for Claude Code. Runs a local MCP server that
connects to the Telegram Bot API via a user-created bot token.
Built-in access control: inbound messages are gated by an allowlist
(default: pairing mode), outbound sends are scoped to the same allowlist.
The /telegram:access skill manages pairing, allowlists, and policy.
Ships full source — server.ts runs locally via bun, started by the
.mcp.json command. First external_plugins entry to bundle source rather
than point at a hosted MCP endpoint.
