linkedin_posting

Create LinkedIn post (not shipped)

deprecated

NOT SHIPPED YET: publish a LinkedIn post (text plus optional media) from one of the team’s accounts. The browser-plugin create-post verb is not built, so every valid call returns not_implemented (context.reason=blocked_on_plugin). Do not retry. The request contract is final and validated in full BEFORE the 501 (text ≤ 3000, media ≤ 9 items each content_base64 XOR url, visibility in the enum), so integrations can be built and tested against it today. Once live it is identity-bound and non-creditable: linkedin_account_sid REQUIRED, spends the posting bucket (5/day, 1200 s delay, the tightest write limit), saturation returns 429 with no pool fallback. Nothing is stored here; the response carries the published activity URN plus the activity-log row.

Not shipped yet. The registry marks this route availability=stub_501: the backend validates the whole request and then answers 501 not_implemented. The request contract is final, so integrations can be written and tested against it today. Marked deprecated so generated clients flag it at compile time; this is a NOT-YET flag, not a sunset.

Contract:

MCP tool create_linkedin_post, registry package mcp.linkedin/linkedin_posting, mount linkedin.content.
Operation action, response envelope action.
Flags: dangerous: the MCP layer gates it behind a preview/commit token, and the effect cannot be undone through this API.
