Growth systems, the craft of writing, and how the Twitter and LinkedIn algorithms actually rank you. No virality hacks.
We were going to write that connecting one assistant to both Twitter and LinkedIn was rare. It is not. More than twenty connectors do it and several are free, so channel coverage is table stakes and every roundup ranking them by it is measuring the wrong thing. Here is what actually differs between them, and the one thing we read enumerated tool lists for six of them to confirm nobody does at all.
X publishes three official MCP servers, and the one everybody installs cannot create a post. You can prove that from its OAuth scopes, which do not include write access to posts at all. Meanwhile every guide prices this as fifteen thousandths of a dollar per post, which is the sticker price and not the bill. A realistic assistant session costs two to eighteen times that, and the difference is mostly links.
Every guide on this question says no, and every one of them is now out of date. Some time between 11 July and 5 August 2026, LinkedIn put a Develop with MCP link on its developer homepage, badged it New, and made it the first thing you see. It has documented that precisely nowhere. Here is what is verifiably there, what is still missing, and the install trap that catches people looking for an official server in the meantime.
There are dozens of free Claude skills for writing, and almost all of them do the same thing: strip out phrases that read as machine-written. That is subtraction, and it leaves you sounding like nobody in particular rather than like yourself. The handful that actually learn a voice from your own writing have a fraction of the users. Here is the difference, why a skill cannot post anything no matter what it says, and where the file actually goes on every surface.
Claude can publish to LinkedIn through a connector, using a permission LinkedIn hands out self-serve. The final item in LinkedIn's API Terms of Use is a flat ban on using the APIs to automate posting. Every guide we read cites the wrong document, and several sell scheduling while calling themselves the compliant option. Here is the clause, what Claude can and cannot actually publish, and why the connector most people recommend cannot work on claude.ai at all.
Every comparison of LinkedIn MCP servers sorts them by stars, tools and terms risk. None of them mentions that the ones using LinkedIn's sanctioned login die after 60 days and cannot renew themselves. We went through the field server by server. Only a handful use that route at all, most of those are abandoned, and the ones that never expire avoid the problem by holding a credential that lasts a year and cannot be revoked individually.
The rate card is published, and it is the least useful part of the answer. What decides your bill is that billable events are not API calls, that one attached image doubles a post's cost, that the same post costs five times more to read through one endpoint than another, and that the monthly read cap changed three times this year with no announcement. Plus the failure nobody has written down: what the API actually returns when the money runs out, which we measured because it happened to us.
The settled wisdom is that LinkedIn gives you no way to read your own post performance programmatically. That stopped being true on 8 July 2025, when LinkedIn shipped a member post analytics endpoint with eleven metrics. We read seventeen pages that rank for this question and only three name it. Here is what exists, who can actually get it, the metrics LinkedIn will not give a personal profile at all, and the storage question LinkedIn has never answered.
Every answer to this question is confident and none of them cite anything. This one quotes the clauses. LinkedIn's user agreement names browser plugins specifically, the three routes an MCP server can use to reach your account land in very different places against it, and the enforcement cases everyone repeats are about companies rather than members. Including the part most vendors leave out: our own Chrome extension sits inside the clause we are quoting, and we would rather tell you that than claim otherwise.
Hootsuite starts at $99 per user a month, not $19. Here is what the realistic alternatives cost, read off each vendor's own pricing page in both billing positions, plus the clause in Hootsuite's terms that its pricing page does not mention.
A Twitter search ban is the one part of a "shadowban" that can actually be verified: your posts stop appearing in search. This is what Twitter's own documentation says about it, how to test it by hand in under a minute, the six behaviours Twitter names as causes, and why nobody can tell you how long it lasts. Plus the distinction almost every guide misses, between enforcement that Twitter applies to you and ranking that simply does not favour you.
Four LinkedIn tools people move to from Taplio, priced from each vendor's own pricing page rather than from each other. Includes the arithmetic on Taplio's Pro tier, which does not add up, and one name still on every recommendation list that has quietly shut down.
Why VoiceMoat
VoiceMoat is a social media marketing platform for Twitter and LinkedIn. It trains on what you have already published, drafts against that, and scores every draft so you can see what does not sound like you before it goes out.
A voice profile built from everything you have published, held separately for each platform.
Every draft comes back rated against that profile, with the lines that miss named individually.
Post to Twitter and LinkedIn, or queue a week, without leaving the draft you are working on.
Your real impressions and engagement, read in rate rather than in raw count.
