starnikovoleg/tgatlas-mcp

MCP server for public Telegram channels. Gives an agent a channel's real
profile — subscribers, description, creation date, verification and scam
flags, how often it posts — and the channels Telegram itself considers
similar to it.
No phone number, no session file, no MTProto client to keep alive. An API
key and a Node runtime.

Tools
telegram_channel
A channel's profile: title, description, exact subscriber count, creation
date, Telegram's own verification and scam flags, and posting cadence.
The cadence is the part most directories leave out, and it is usually the
answer to the question being asked. A channel with 200,000 subscribers and
nothing published in fourteen months looks identical to a live one in every
listing that reports only follower counts.
telegram_similar_channels
The channels Telegram recommends alongside a given one — its own topical
judgement rather than a keyword match, so it returns channels that share an
audience without sharing vocabulary.
This is how you find channels whose names you do not already know: start
from one you do and walk outward. Two rounds of expansion from a few dozen
seeds reaches several thousand channels.
Set enrich: true to fetch exact subscriber counts for each result.
telegram_search_channels
Telegram's global search over public channels and groups. Use it to find a
starting point; use telegram_similar_channels to expand it.
Output
Markdown by default — what a model reads without a parsing step. Pass
format: "json" for the raw API response when you are piping into code.
Scope
Public channel metadata only. Message contents, member lists, and private
groups are outside what this reads and outside what it will return.
Cost
Tools call the REST endpoints directly rather than proxying a remote MCP
endpoint. RapidAPI bills per request, so this arrangement means initialize
and tools/list are free: you pay for lookups, not handshakes.
telegram_channel costs three calls with cadence on, two with
cadence: false. telegram_similar_channels costs two, plus one per result
when enrich: true (capped at 12).
