Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md.

This is n24q02m/better-telegram-mcp's own configuration. It tells Claude Code how to work on better-telegram-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything better-telegram-mcp configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is cd ../mcp-core && uv run --project scripts/e2e python -m e2e.driver <config-id>.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

better-telegram-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Auth flow

Stdio mode (default): local single-user mode. Bot mode uses TELEGRAM_BOT_TOKEN; user mode can be configured with the local auth CLI (login is a deprecated alias).

HTTP mode (--http / MCP_TRANSPORT=http): mcp-core run_http_server serves the local OAuth AS at /authorize. The custom credential form collects bot_token OR phone, posts to /save, and chains OTP / 2FA via /otp.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
