ContentIn, LinkedIn Ghostwriter is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
list_postsList the posts on this ContentIn profile — drafts, scheduled, published and ideas. Use this to find a post's id before scheduling, publishing, repurposing or pulling analytics for it, and to answer questions about what the user has written or has queued up. Returns a 280-characteget_post_analyticsGet LinkedIn performance for one published ContentIn post: impressions, members reached, likes, comments, shares, and a derived engagement rate. IMPORTANT: metrics are fetched on a schedule and only for posts published through a connected LinkedIn account, so a post can legitimatlist_my_commentsList the comments this user has left on OTHER people's LinkedIn posts, newest first, with the comment urn and a direct link to each one. Use it to review their commenting activity, to find a conversation they joined, or to hand the identifiers to another tool. HOW THIS DATA IS COlist_leadsList the people who engaged with THIS user's own LinkedIn posts — their name, headline, LinkedIn profile, how they engaged, what they commented, which posts pulled them in, and ContentIn's ICP fit score. Use it to answer 'who is engaging with me', to find warm contacts, or to seewrite_post_in_my_voiceTHE MAIN TOOL. Write a LinkedIn post in this user's own voice, from their own material. Use it whenever the user describes something they want to post about — a story, an opinion, a result, a lesson, a rough brief. It runs ContentIn's voice pipeline: their VoiceDNA, their real paattach_imagesAttach one or more images to a ContentIn post that is not published yet. IMAGES ONLY — JPG, PNG or WEBP, at least 200×200px, at most 8 MB each, and at most 5 per post. Video, GIFs, PDFs and document carousels are NOT supported and will be refused, so do not try to attach one. Pasrepurpose_postRewrite an existing post from a new angle, in the user's voice. Pass post_id (a ContentIn post id from list_posts) to repurpose one of their own posts — the current text is read from ContentIn, so you do not need to have seen it. Pass original_post instead to repurpose text you agenerate_ideasGenerate fresh LinkedIn post ideas for a COLD request — the user wants options but has NOT given you material of their own ('what should I post about this week?', 'ideas for [topic]'). Ideas are grounded in the user's content pillars and their substance bank, so they are theirs rcapture_substanceSave a piece of the user's first-party substance — a story, an opinion, a data point, or a framework — into their ContentIn content bank, filed under one of their content pillars.
