  • search_postsFull-text search over recent posts from catalogued channels (1k+ view posts).Reads text others writeNo findings

    Why it is in this group

    • The name "search_posts" says "search": a word for reading.

    What it can reach

    • untrusted-inputThe name "search_posts" says "search" and "post": it reads posts, which other people can write.
    • untrusted-inputThe description's first sentence says "post": it reads posts, which other people can write.
    Description, as the server wrote it
    Full-text search over recent posts from catalogued channels (1k+ view posts). Returns text snippets, channel and view counts.
  • search_telegramFull-text search over the tgden catalog (1.7M+ channels, 422k+ group chats, 228k+ bots) with subscriber/member counts, categories and trust scores.Reads private dataReads text others writeNo findings

    Why it is in this group

    • The name "search_telegram" says "search": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "chat": it reads messages.
    • untrusted-inputThe description's first sentence says "chat": it reads messages, which other people can write.
    Description, as the server wrote it
    Full-text search over the tgden catalog (1.7M+ channels, 422k+ group chats, 228k+ bots) with subscriber/member counts, categories and trust scores. Needs no Telegram account — this is the public catalog, so it finds communities the user has NOT joined. Use type to restrict to one entity kind.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged outbound.

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write2
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

  • WarnThe whole server

    The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://tgden.com/api/mcp: tools/list returned 6 tools to an anonymous client, including channel_stats (write), market_listings (write), market_stats (write), best_channels_by_category (write)

    What this check looks for

Install

Pinned to version 1.1.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http telegram-catalog https://tgden.com/api/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__telegram-catalog__search_telegram",
      "mcp__telegram-catalog__search_posts"
    ],
    "ask": [
      "mcp__telegram-catalog__channel_stats",
      "mcp__telegram-catalog__market_listings",
      "mcp__telegram-catalog__market_stats",
      "mcp__telegram-catalog__best_channels_by_category"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as telegram-catalog. Review it before you use it.
