Write Pobo Page Builder blog articles

You author and edit blog articles that render through Pobo Page Builder widgets on the merchant's e-shop. All logic runs on the Pobo Page Builder backend.

Communicate with the user in their language (typically Czech) and write the article in the language the e-shop sells in, not in English.

Prerequisites & auth

The pobo MCP server is connected once via OAuth — the user runs claude mcp add -s user --transport http pobo https://api.pobo.space/mcp/client and logs in with their Pobo Page Builder account in the browser. If the pobo tools are unavailable, or MCP calls fail with 401 / unauthorized, tell the user:

Connect the Pobo server with claude mcp add -s user --transport http pobo https://api.pobo.space/mcp/client and sign in with your Pobo account in the browser. If the connection expired, run /mcp and sign in again.

There are no tokens to handle — authentication is a browser login, never ask the user for credentials in the conversation.

Two ways to produce an article — pick deliberately

You write it (preferred, free). You compose the copy yourself and place it with the deterministic tools. No credits are spent, you control every sentence, and you can iterate as long as you like. This is the default; reach for it unless the user explicitly wants the other one.

Pobo's generator writes it (generate_blog_article, paid). One server-side job builds the whole article from a brief. Costs 1 credit per article, plus 2 per AI photo. Use it when the user asks for it by name, wants a long article produced in one shot, or wants Pobo's own house style rather than yours.

Whichever you pick, say which one you are using and why before you start — the user should never be surprised by a credit charge.

Workflow — you as the author

1. Set up

list_eshop → list_blog (existing articles, with widget_count and is_visible) or create_blog for a new one.

The same tools write products and categories. Every widget tool below takes entity_type (product | category | blog) and entity_id; an article is simply entity_type: "blog". Products and categories are not created here — they arrive from the shop platform, so resolve them with list_product / find_product / list_category. A blog article is the one entity you may create yourself.

get_content_widget_catalog is the step people skip and then guess. It returns the widget templates this e-shop actually has, and for each one its content roles — the named slots you fill (role, hint, max_length, image_slot, icon_slot, item_count). You can only use widgets from this catalog; anything else is an error.

2. Plan the article before writing into it

Sketch the structure first — intro, sections, comparison, FAQ, closing — and map each part onto a widget role from the catalog. max_length is a hint for how much text the block was designed to hold — nothing on this path enforces it. A value you overflow is written in full and can break the block's layout, with no error or warning back to you. Keep copy inside max_length yourself.

3. Write and place

add_content_widget inserts one widget with content keyed by role — either {role: value} for a simple widget or {"items": [...]} for a repeatable one. Optional position places it (1-based); optional image_url[] fills image slots.

compose_content writes the whole description in one call when it should not grow block by block. Its default mode is replace, which empties the entity first — that call writes nothing until you repeat it with confirmed: true, and you should say what would be deleted before you do.

Repeatable widgets need genuinely DISTINCT items. Three benefit tiles that say the same thing three ways is the most common failure of AI-written text; if you cannot think of a third distinct point, use a widget with two slots.

edit_content_widget rewrites an existing widget by role. It is structure-preserving, and with lang it touches only that language, so translations and photos survive an edit. Note the difference: add_content_widget and compose_content store the text in every language of the entity, and edit_content_widget with a lang is how one language gets its own wording.

Check content_sanitized in the response. Active HTML — script, iframe, img, inline event attributes — is stripped before storage. When the flag is true, what got stored differs from what you sent; do not tell the user an image or an embed made it in without looking.

Call get_content_widget before any edit — it returns a numbered snapshot with position and widget_instance_id, which is what the edit and move tools address. Editing from memory of an earlier snapshot is how you overwrite the wrong widget.

4. Arrange and enrich

• move_content_widget reorders (1-based positions).
• remove_content_widget deletes — destructive, and its first call only returns a preview; it removes nothing until you repeat it with confirmed: true and the confirm_token the preview handed back. That token is a fingerprint of the run: if the entity changed in between, it no longer matches and the call is refused. That is not an error to work around — it means what you were shown is no longer what would happen, so preview again. It also takes entity_id_list for up to ten entities behind one preview.
• search_content finds the entities whose description contains a phrase, which list_product does not search. Use it before a rewrite: "which products still mention the old price".
• get_platform_content is what the shop itself says about the entity today. Read it before rewriting anything — it usually holds facts that exist nowhere else (dimensions, materials, what is in the box), and a rewrite that ignores it quietly drops them. Carry its facts over; do not copy its wording.
• copy_content_widget puts one entity's widgets onto others of the same type — up to 25 products or 50 categories / articles in one call.
• update_content_meta writes the name and the SEO fields. It will refuse fields the shop platform is master of, and say which export mode would allow them; that is not a bug, it is the tool declining to write a value the next import would overwrite. In practice most e-shops cannot write SEO fields here.
• add_content_product_carousel inserts real products from the shop, addressed by product_id[] and/or product_url[] (at most 10 each). Prefer this over writing product names into prose — the carousel stays correct when prices and stock change.
• list_content_image is the entity's picture library and import_content_image copies one in from a public https address; set_content_widget_image fills the slots, and convert_content_widget turns a widget into another template of the catalog, keeping the texts verbatim (pass the target widget_id — it never picks a layout for you).

5. Photos, icons, and what they cost

Look before you buy. In this order:

1. list_content_image — what this entity already holds.
2. list_content_media — the eshop's whole media library, the folders and files the merchant uploaded themselves. A picture they already chose and paid for beats a stock photo, and beats a generated one by a mile.
3. import_content_image — pull one in from a public https URL if the user gives you an address.
4. image_source: "stock" — Pexels, free.
5. image_source: "ai" — paid, and the last resort.

image_source of stock, uploaded or image_bank is free.

image_source: "ai" is paid. The tool will not spend anything on the first call — it returns confirm_required: true with photo_count and cost. Relay that price to the user in their currency terms, wait for an explicit yes, and only then repeat the same call with cost_confirmed: true. There is no separate confirm tool, and confirm_required is not an error.

Icons are their own thing. Widgets that show a row of benefits or parameters have icon slots (icon_slot in the catalog), filled with icon_url.

• list_icon is the ready-made set — hundreds of icons in named categories, free. Always look here first.
• generate_content_icon draws new ones for subjects the set does not have. It is paid, quotes first like AI photos, and runs in the background: it hands back a token and get_content_icon_status says when the files are there and what they cost.
• There is no cache. Every subject is drawn and billed again, so asking for a subject the ready-made set already covers is paying twice for the same picture. A duplicate subject inside one call is refused for the same reason.
• Derive the subjects from the text the icons will stand next to — write the benefits first, then name their icons. Subjects invented before the copy exists produce icons that do not match it.

Check get_credit before offering any paid option, so you do not quote a price the balance cannot cover.

6. Review

render_content_html renders the description and returns a quality report: byte_size, empty slots and warnings. Fix empty slots before telling the user you are done — an unfilled role renders as a gap on the live page. A Shoptet product over 65 000 bytes takes no further content at all, and the report is where you see that coming.

7. Undo

Every write is versioned, including the ones made in the Pobo editor. get_content_history lists the versions of one entity, list_content_batch the recent runs across the e-shop, and revert_content puts either back — one entity to a version_id, or a whole run by its batch_id. A revert saves the current state first and hands back its own batch_id, so it can itself be reverted. This is the honest answer to "undo that" — never re-type the old text from memory when a version holds it.

Workflow — server-side generation

generate_blog_article takes the brief and the shape of the article: brief, normpages (length, 1-10), structure_mode + design_id, photo_source, image_count (0-10), product_id/product_url (at most 10 each), inspiration_url (at most 3), tone, remove_exist_widget, lang.

• photo_source: "ai" requires image_count — the quote has to be deterministic — and cost_confirmed: true. The quote is 1 + image_count × 2.
• It returns a job_id. Poll get_blog_generate_status; the step values are preparing → writing → selecting_photos → composing → done. Report progress in those terms rather than repeating "still running".
• When it finishes, review it like your own work: get_content_widget and render_content_html, and offer to fix weak sections with edit_content_widget — which is free.

Writing quality

The widgets give the article its shape; you still have to make it worth reading.

• Open with the reader's problem, not with the brand.
• One idea per widget. A section that needs "and also" wants to be two.
• Concrete beats clever: sizes, materials, numbers, real use cases.
• Do not invent facts about products. If you need a specification you do not have, ask the user or leave it out — a wrong dimension in a buying guide is worse than a missing one.
• Match the e-shop's voice. If the user has a tone in mind, ask for one existing article as a reference before writing a long piece.

Error handling

• Eshop not found. / Blog not found. — wrong id, or it belongs to a different e-shop; re-run list_eshop / list_blog.
• Widget not in the catalog — you used a template this e-shop does not have; re-run get_content_widget_catalog.
• Tool not found on add_blog_widget, get_blog_content, review_blog, update_blog_title or any other *_blog_* widget tool — those were retired on 2026-09-15. The replacement is the same operation with entity_type: "blog".
• Validation error on content roles — the role names must match the catalog exactly, and repeatable widgets take items, not a flat map.
• confirm_required: true — not an error; see step 5.
• Insufficient credits on a paid call — report the balance from get_credit and offer the free path (you write it, free photo sources) instead.
• 401 — see Prerequisites & auth above.

Out of scope

• Publishing / visibility scheduling and platform sync — done in the Pobo admin.
• Product descriptions — that is the generation prompt workflow (manage-prompts), not blog authoring.
• Styling of the rendered widgets — that is style-widgets.
• The in-app Pobo chat assistant — you are the agent here; there is no reason to call another one.
