Hermoso is a marketing MCP server: 850+ tools over one OAuth’d endpoint that let an agent research the ads already running in a market, generate finished image and video ads, publish them, and build the paid campaigns behind them. Claude reaches all of it through one connection. This page is about one slice of that — what Claude can actually do on Telegram, and what Telegram will not let it do.
Connect Hermoso to Claude
- Copy the connector URL.
https://app.hermoso.ai/mcp - Claude → Settings → Connectors → Add custom connector. Name it Hermoso and paste the URL.
- Connect and approve. Sign in with your Hermoso account on the consent page. There is no key to paste — the connector signs in with OAuth and mints its own.
- Ask Claude for something. “Pull my three closest competitors’ longest-running ads and remix the best hook into a 9:16 video,” or “post this render to the channel.” The agent picks the tools; you approve the spend.
Claude and ChatGPT are the two clients where nothing is pasted: the hosted connector runs a full OAuth handshake with PKCE and dynamic client registration, and the key it mints is scoped to the brand workspace you approved it against — pinned on the server, not read off the request.
Then connect Telegram itself, once, under Settings → Connectors in Hermoso by pasting a bot token from @BotFather, and add that bot to your channel as an administrator. There is no consent screen: the token is the credential, and the bot is who posts.
The Telegram tools Claude gets
post_to_telegram— sends a message as your bot to the chat you name: text up to 4,096 characters, or one photo, one video, or an album of 2 to 10 with photos and video mixed.schedule_post— queues it with itschatIdon the same calendar as every other channel.list_telegram_chats— the chats that messaged the bot in the last 24 hours. It helps find an id, and it is not a list of every chat the bot is in.edit_telegram_message / pin_telegram_message— fix a message’s text or caption without losing its views, and pin or unpin the call to action.create_telegram_invite_link— a named invite link per campaign, with an optional expiry, member cap or join approval, so you can see who joined from where.telegram_account— the chat’s subscriber or member count, title, description and invite link.list_telegram_dms— what people sent the bot in the last 24 hours, newest first, to answer withpost_to_telegram.delete_telegram_message— removes a message the bot sent, within Telegram’s 48-hour window, after a confirm step.
Telegram connects with a bot token, not a sign-in screen. Make a bot with @BotFather in Telegram, paste its token under Settings → Connectors, then add the bot to your channel as an administrator with Post Messages, or to a group as a member who can post. Hermoso posts as that bot, never as you. Two limits are Telegram’s and worth planning around: a bot gets no per-post views and no post history, so the subscriber count and named invite links are the numbers you have; and messages sent to the bot are kept for 24 hours, then gone. Publishing costs no credits.
Telegram limits worth knowing before you automate anything
| Text | A Telegram message runs to 4,096 characters, but only 1,024 once a photo or video is attached, because the text becomes a caption. It is enforced when the post is created or queued — refused while you are still there to fix it, rather than silently cut on the way out. |
|---|---|
| Visibility | Sent or not sent, with no draft, unlisted or private form. Who sees it is decided by the chat: “post to a private group or channel and only its members see it.” silent delivers without a notification sound and changes nothing about who can see the message. |
| Carousel | 2 to 10 items as an album, and photos and video may be mixed. Both bounds are Telegram’s own, from the Bot API’s sendMediaGroup (“must include 2-10 items”), and so is the mixing. The album shows one caption, on its first item. Hermoso uploads the files instead of passing links, which raises Telegram’s ceilings to 10MB per photo and 50MB per video. |
| Which account | chatId, required on every post: a public channel’s @username or the numeric id (a supergroup or channel starts with -100). The Bot API has no method that lists the chats a bot is in, so Hermoso cannot know them and never guesses. |
Try it in Claude
Ask for it in ordinary language — these are sentences, not a DSL:
“Post this render to @ourbrandchannel on Telegram with a caption under 1,024 characters, then pin it and make a named invite link for the newsletter.”
That walks render_ad → post_to_telegram → pin_telegram_message → create_telegram_invite_link. Every tool call happens inside the conversation, so you see the Page, the board or the caption before anything publishes, and you can stop it by saying so.
Claude on Telegram: the part that bites
Give Claude the chat’s @username or numeric id in the ask. There is no roster to pick from: the Bot API has no method that lists a bot’s chats, and list_telegram_chats only shows chats that messaged the bot in the last 24 hours, so a channel it posts to every day can be missing from it. The bot also has to be in the chat already, as an admin with Post Messages in a channel. If it is not, the error says to add it rather than to reconnect.
Claude Desktop uses the same Connectors flow as claude.ai — there is no separate desktop setup.
Research Telegram before you post
There is no Telegram ad library and no channel search in Hermoso, so it claims no competitor research on Telegram. Research the creative where it is public (the Meta, Google and LinkedIn ad libraries plus organic TikTok, Instagram, YouTube, Reddit and Threads) and post the finished ad here.
The paid half
There are no Telegram ads in Hermoso, and we do not imply any. Telegram here is a channel you own and run through your bot: post, pin, edit, count subscribers and track invites. The paid tools cover Meta, Google Ads, Microsoft Advertising, Reddit Ads, LinkedIn, Pinterest, X Ads, TikTok Ads, Snapchat Ads, ChatGPT Ads and Apple Search Ads.
What Claude cannot do on its own
An agent with a budget is only useful if the blast radius is bounded, so the fence is in the server rather than in a prompt. Every ad campaign, ad set, ad group and ad is created paused, and the status switches that arm real money refuse to run without an explicit confirmation flag. Every render is quoted first — hermoso_capabilities publishes each model’s exact credit cost before anything spends — and credits are reserved before the first provider call and settled at the exact cost afterwards, so a failed dispatch refunds rather than leaving you billed for nothing. Deletes are confirm-gated too, and every campaign tree is read back from the ad platform before your agent tells you what it built.
One step is deliberately yours: creating the bot with @BotFather and adding it to your channel. Everything after that is a tool call.

Frequently asked questions
Can Claude post to Telegram?
Yes, through Hermoso's MCP server. In Claude, add https://app.hermoso.ai/mcp as a custom connector and approve it with your Hermoso account — there is no key to paste. Claude then has 850+ tools, including the ones that publish to Telegram — and the ones that research the ads already running in your market and render the creative in the first place.
How do I connect Telegram to Claude?
Two steps, once each. In Claude, add https://app.hermoso.ai/mcp as a custom connector and approve it with your Hermoso account — there is no key to paste. Then make a bot with @BotFather in Telegram, paste its token under Settings → Connectors in Hermoso, and add the bot to your channel as an administrator with Post Messages. After that Claude publishes to Telegram as an ordinary tool call, naming the chat each time.
Can Claude post a carousel to Telegram?
Yes, as an album of 2 to 10 items with photos and video mixed, which is Telegram’s own rule for sendMediaGroup. The album carries one caption, on its first item. Claude calls the same publish tool either way, and a channel that cannot carry a carousel is refused with the real reason attached.
What does it cost to post to Telegram from Claude?
Posting to Telegram costs no credits; Telegram charges nothing per call. Credits are spent on generating the creative. Plans are $19, $49 and $149 a month for 1,000, 3,000 and 10,000 credits, and every feature is on every plan including Free — the only exception is enterprise SSO.
Start free — 30 credits at signup and 250+ more to earn, and every feature on every plan. Credits are spent only on AI models and Ad Spy research; posting, scheduling, ads management and analytics are free.
