LinkedIn

Skill for publishing to LinkedIn through the LinkedIn integration exposed by the Hyper MCP.

Out of scope — defer to other skills

Requirements

• Hyper MCP installed and connected. https://app.hyperfx.ai/mcp
• LinkedIn integration connected at https://app.hyperfx.ai/apps.
• For company-page posts, the connected member account must have permission to post for that organization.

If search("linkedin_text_posts_create") does not find linkedin_text_posts_create, stop and tell the user to enable Hyper MCP and connect LinkedIn.

How to run the tools in this skill

Every tool in this skill is named by its canonical tool name. Run it with the call your surface gives you:

If a tool is not found, its integration is not connected or not enabled for the workspace: stop and tell the user which integration to connect.

Posting Rules

1. Use linkedin_text_posts_create for standard member or organization posts.
2. Use linkedin_organization_posts_create when the user explicitly wants to post as a company page and you already know the organization_id.
3. Use linkedin_document_posts_create for PDF / document uploads. LinkedIn renders PDF pages as a swipeable document post.
4. Use linkedin_carousels_create_from_text when the user wants a text-to-carousel workflow driven by AI-generated slides.

Article / Link Posts

Do not rely on LinkedIn to scrape Open Graph metadata for API-created posts.

For reliable article posts:

• Provide article_url.
• Prefer explicit article_title, article_description, and thumbnail_url.
• If those fields are omitted, the backend may derive them from the shared page metadata, but explicit values are still more reliable.

Use this shape when editing or preparing a LinkedIn article post:

linkedin_text_posts_create(
    text="Caption text",
    article_url="https://example.com/article",
    article_title="Explicit preview title",
    article_description="Explicit preview description",
    thumbnail_url="https://example.com/thumbnail.jpg",
    organization_id="123456789",  # optional
)

Document and Carousel Posts

LinkedIn carousels are implemented as document posts backed by a PDF.

Native PDF flow

Use linkedin_document_posts_create when you already have a PDF URL or stored file ID:

linkedin_document_posts_create(
    text="Caption text",
    title="Deck title",
    document_url="https://example.com/deck.pdf",
    organization_id="123456789",  # optional
)

Text-to-carousel flow

Use linkedin_carousels_create_from_text when the user wants the system to build the carousel from a block of source text:

linkedin_carousels_create_from_text(
    text_content="Source content for the slides",
    title="Carousel title",
    caption="LinkedIn caption",
    num_slides=4,
    style="professional",
    color_scheme="blue",
    organization_id="123456789",  # optional
)

The current implementation:

• Parses the source text into slide content.
• Generates a single grid image with an image model.
• Splits the grid into individual slide images.
• Assembles a PDF.
• Publishes the PDF as a LinkedIn document post.
• Returns the live post URL — present this to the user to confirm the carousel is live.

Supported slide counts are 4, 6, and 9.

Manual Slide Editing

The current LinkedIn carousel pipeline is PDF-based. It does not provide a first-class live canvas editing loop before publish.

If a user wants manual refinement:

1. Generate the carousel assets first.
2. Review or edit the generated slide images / PDF externally.
3. Post the final PDF with linkedin_document_posts_create.

Do not promise an in-product editable canvas workflow unless the tool is actually available in the current environment.

Organization Posting

When posting to a company page:

• If you don't know the organization_id, call linkedin_managed_pages_list() first — it returns all company pages the connected account can post to, with their IDs.
• Use linkedin_organizations_posts_list_detailed(organization_id=...) to preview recent posts before publishing — avoids accidental duplicates.
• Pass organization_id to whichever posting tool you're using.
• Expect LinkedIn org posting permissions to matter.
• If a post fails with a permissions error, verify that the authenticated account can post to that organization.

Failure Modes & Recovery

• Article preview is empty / wrong. LinkedIn ignored the scraped metadata. Re-call linkedin_text_posts_create with explicit article_title, article_description, and thumbnail_url.
• Permission error on organization post. Confirm with the user that their LinkedIn account has page-posting permission for the target organization_id.
• `linkedin_carousels_create_from_text` returned an unexpected slide count. Only num_slides of 4, 6, or 9 are supported.
• Document post fails with an invalid URL. The document_url must be a directly-fetchable PDF (no auth, no HTML redirect page).
