ContentIn for Agents

npx add-mcp 'https://mcp.contentin.io/mcp-server'

LinkedIn for AI agents

Post to LinkedIn from Claude or ChatGPT, free. Add a plan and your AI gets your results, your voice and your past posts.

Free, no card: up to 2 posts a day and 30 a month per LinkedIn profile. Plans for your data and ContentIn's writing start at $29 a month or $276 a year. Already on Growth or Pro? It's included.

Works with the agents and automations you already run

Claude, ChatGPT and Claude Code connect with the server URL and a ContentIn sign-in. Gemini connects through Gemini CLI. OpenClaw and n8n connect with the same URL and an API key, so a workflow can run without anyone opening a browser. Also works in Cursor and VS Code.

What changes when your agent is connected

You keep the agent you like. ContentIn gives it the four things a model can't know on its own, so the posts it helps you ship sound like you, perform better and bring in people you can talk to.

Your voice and your own material

ContentIn learns your voice from the posts you've already published and keeps a bank of your stories, opinions and numbers. Before it writes, your agent reads your voice, your rules, your saved material and your best posts, so whatever model you use (Claude, ChatGPT, Gemini) can write the post itself. Or it asks ContentIn to write the draft. When you ask it to, it saves new material to the bank from any conversation or workflow.

The outcome: You keep your favourite AI and it writes like you, from your real stories and numbers instead of invented ones, and stops sounding like every other agent. Less rewriting before you post.

get_voice_context write_post_in_my_voice capture_substance

What actually worked on your account

Your drafts, scheduled and published posts, with impressions, members reached, reactions, comments and shares per post, from LinkedIn's official API.

The outcome: Your agent picks topics and formats from your own results instead of guessing, so you post more of what performs for you.

list_posts get_post_analytics

The people who engaged, scored against your ideal customer

Everyone who reacted to, commented on or shared your posts, with ContentIn's fit score against your ideal customer, lead status and the posts that pulled them in. Plus the comments you left on other people's posts and what they got.

The outcome: Your posts turn into a short list of buyers to talk to, and you can see which posts attract them.

list_leads list_my_comments

Agent Pro, or Pro if you use the web app.

A safe last mile

Posts go out through LinkedIn's official API, with up to five images. Before anything is scheduled or published, your agent has to show you the exact text and get your yes. Your agent never logs into your LinkedIn account and never touches your password or cookies.

The outcome: No account restrictions from session or browser automation, and nothing goes out that you haven't read.

schedule_post publish_post attach_images

Free on every account: up to 2 posts a day and 30 a month per LinkedIn profile. Agent plans allow up to 5 a day.

ContentIn also has its own idea and rewrite tools (generate_ideas, repurpose_post). Your agent can use them when it helps; it stays in charge.

The same agent, with and without ContentIn

Your agent on its own

• Writes in the same polished tone as every other agent.
• Fills gaps with plausible stories and numbers you never gave it.
• Doesn't know which of your posts worked, so it guesses at topics.
• Can't tell you who read your posts or whether they could buy from you.
• Posting means copy-paste, or browser automation that risks your account.

Your agent connected to ContentIn

• Reads your voice, your rules, your saved material and your best posts before it writes.
• Uses the stories, opinions and numbers you saved, and saves new ones as you talk.
• Reads the results of your own posts before suggesting the next one.
• Lists the people who engaged, scored against your ideal customer (Agent Pro).
• Schedules or publishes through LinkedIn's official API after you confirm the text.

Use it in automations

Put your LinkedIn into n8n or OpenClaw workflows

In n8n, add an MCP Client node set to HTTP Streamable, point it at the server URL and send your API key in the X-MCP-Key header. OpenClaw takes the same URL and header. Three workflows that run on the tools that are live today:

Monday LinkedIn report

1. 1.A weekly schedule trigger starts the workflow.
2. 2.It pulls last week's posts and their analytics, and the new people who engaged.
3. 3.An AI step summarises what worked and who to follow up with, and posts it to Slack or your CRM.

list_posts get_post_analytics list_leads

Why it pays off: You start the week knowing what to post more of and who to talk to, without opening LinkedIn.

The lead list needs Agent Pro or Pro.

Note or voice memo to draft

1. 1.A note, or a transcribed voice memo, lands from another app.
2. 2.The workflow saves it to your material bank, then asks ContentIn for a draft in your voice.
3. 3.The draft waits in ContentIn. You read it and confirm before it's scheduled.

capture_substance write_post_in_my_voice

Why it pays off: Ideas you'd have forgotten become drafts in your voice, built from what you actually said.

New leads into your CRM

1. 1.Once a day, the workflow asks for the people who engaged with your latest posts.
2. 2.It keeps the ones with a high fit score for your ideal customer.
3. 3.It adds them to your CRM or a sheet, with the post that brought them in.

list_leads

Why it pays off: Engagement turns into a follow-up list you can work, not a notification you scroll past.

Needs Agent Pro or Pro. Today the workflow checks on a schedule; pushing new leads the moment they appear needs Webhooks, which is not available yet.

API keys are created on the ContentIn for Agents page, under Connect your AI. On ContentIn Growth or Pro, they are under Profiles → Connections. Each key acts for one profile. The steps for n8n, OpenClaw and Gemini CLI are in the setup guide.

Thirteen tools live today, four coming in Q4 2026

Your agent picks the tool from what you ask. You never call them by name. Each connection is bound to one LinkedIn profile; agencies connect one per client profile.

Agent tools are included in Agent, Agent Pro, Growth and Pro. Agent Pro tools are included in Agent Pro and Pro. Rows marked “Coming Q4 2026” are not available yet. Details below.

How it starts

From sign-up to your agent working with your LinkedIn

The first three steps are free and need no card. Your AI is posting for you before you decide on a plan.

1. Add your LinkedIn profile

   Create your free account from this page and paste your LinkedIn profile URL. ContentIn reads your published posts and learns your voice from them in about a minute. Your voice profile shows how you write, a passage that sounds like you and the posts that did best.

2. Connect LinkedIn for publishing

   Connect your LinkedIn account on the ContentIn for Agents page. Posts go out through LinkedIn's official API, so your AI never logs into LinkedIn.

3. Connect your AI app

   Add the server URL in Claude, ChatGPT or Claude Code and approve ContentIn. For Gemini CLI, OpenClaw or n8n, create an API key on the ContentIn for Agents page. Your AI can now schedule and publish up to 2 posts a day and 30 a month, free, up to 14 days ahead, with images. It shows you each post and waits for your yes. https://mcp.contentin.io/mcp-server

4. Add a plan for your data and ContentIn's writing

   Pick Agent or Agent Pro and start the 7-day trial. A card is required; cancel before day 7 and you're not charged, and your AI keeps posting on the free allowance.

5. Your AI gets the rest of the tools

   It can now read your analytics and saved material, ask ContentIn to write in your voice and, on Agent Pro, see the people who engaged. Then ask something real: “Which of my last ten posts did best, and what should I write next?”

Per-client steps for Claude, ChatGPT and Claude Code (plus Cursor and VS Code), and API keys for Gemini CLI, OpenClaw, n8n and other agents that can't open a browser, are in the setup guide.

Not available yet

Coming in Q4 2026

Four tools we are building now. They ship once OpenAI and Anthropic have finished reviewing the current version. None of them is available today.

• Coming Q4 2026 Agent

  Search your own posts

  What it does Your AI can search everything you have posted on LinkedIn by meaning. Ask what you already said about a topic and it finds those posts, even when they use other words. Why it helps While it writes, your AI reuses your own stories and numbers, and you stop repeating posts you have already written.
• Coming Q4 2026 Agent

  Comment from your AI

  What it does Your AI posts a comment on one of your own posts, for example the first comment with your link, or on a post you paste. It goes through LinkedIn's official API, after you confirm the exact text. Why it helps The first comment with your link goes out when the post does, without you opening LinkedIn.
• Coming Q4 2026 Agent Pro

  Viral post library search

  What it does Your AI searches ContentIn's library of about 46,000 top-performing LinkedIn posts for examples on your topic. Why it helps Your AI looks at hooks and formats that worked for others on your topic before it writes your post in your voice.
• Coming Q4 2026 Agent Pro

  Engage with your leads

  What it does See recent posts from the people who engaged with you and from your target accounts. Your AI drafts a comment in your voice and posts it after you confirm. Why it helps You stay in front of the people you want to work with in a few minutes a day.

Not planned yet

What to build after that

None of this is live or scheduled. We build in the order people ask for it, so if one of these would change what your agent can do for you, press “I want this”. The post library search was on this list; it is now coming in Q4 2026.

• Not available yet

  Draft check

  What it is Send any draft and get back a voice match score, AI tells, repeats of your old posts, and claims your material doesn't back. What your agent can do Run every draft through a quality gate before it's scheduled, whoever or whatever wrote it. Why it's a better outcome Fewer posts that sound generated, repeat yourself or say something you can't stand behind. I want this
• Not available yet

  Webhooks

  What it is Events pushed to n8n, Zapier or your CRM: a new lead that fits your ideal customer, a lead engaged again, a post was published, analytics are ready. What your agent can do Your automations react the moment something happens instead of checking on a schedule. Why it's a better outcome You follow up with a buyer while your post is still fresh in their mind. I want this
• Not available yet

  Leads to your CRM

  What it is People who engaged, scored against your ideal customer, sent to your CRM with the post that brought them in. What your agent can do Keep your pipeline filled from LinkedIn engagement without a workflow you maintain yourself. Why it's a better outcome More conversations with the right people, without copying names out of LinkedIn. I want this

Frequently asked questions

Do I need the ContentIn web app?

No. ContentIn for Agents is for people who work in Claude, ChatGPT or their own automations. You sign up, paste your LinkedIn profile URL and connect your AI. Your agent does the rest through the tools; there is no web app to learn. One page, the ContentIn for Agents page, shows your setup, plan, connections and scheduled posts.

I already have Growth or Pro. Do I need to buy anything?

No. The MCP server is included in your plan. Growth has every Agent tool and Pro has every Agent Pro tool. Connect your agent with the server URL and the tools work right away.

Is there a free plan?

Yes, with no card. Without a plan your AI can schedule and publish posts through LinkedIn's official API, up to 2 posts a day and 30 a month per LinkedIn profile, up to 14 days ahead, with images, and you confirm each post first. It can also read a short summary of your voice profile (who you are, your mission, what you believe), and you see your full voice profile in your account. When your AI asks how a post did, a free account sees how many people it reached; who engaged, comparisons and what to post next are in the plans. ContentIn's writing, your analytics, your saved material, your leads and your comments need a plan: Agent at $29 a month or $276 a year, or Agent Pro at $49 a month or $468 a year, per LinkedIn profile, each with a 7-day trial.

Can I pay yearly?

Yes. Billed annually, Agent is $276 a year ($23 a month instead of $29) and Agent Pro is $468 a year ($39 a month instead of $49), per LinkedIn profile. You choose monthly or yearly when you start your trial.

What does the trial include?

Seven days of the plan you pick, Agent or Agent Pro, with every tool in it. A card is required to start the trial; cancel before day 7 and you're not charged. If you cancel, your account stays free and your AI can still schedule and publish up to 2 posts a day and 30 a month. One agent trial per account.

What does my agent get that ChatGPT or Claude alone doesn't have?

Your history. A model on its own doesn't know how you write, what you've said before, which of your posts worked or who engaged with them, so it writes like every other agent and fills gaps with invented details. Connected to ContentIn, it writes from your voice profile and your saved stories and numbers, reads your per-post results, sees the people engaging with you scored against your ideal customer (Agent Pro), and posts through LinkedIn's official API after you confirm. The result is posts that sound like you, more of what performs, and leads you can act on.

Which AI agents and automation tools does it work with?

Claude, ChatGPT and Claude Code connect with the server URL (https://mcp.contentin.io/mcp-server) and a ContentIn sign-in. Gemini connects through Gemini CLI. OpenClaw and n8n connect with the same URL and an API key in the X-MCP-Key header. It also works in Cursor and VS Code. Any other agent that speaks MCP over Streamable HTTP can use the same URL and key.

How do I use it in n8n?

Create an API key on the ContentIn for Agents page, under Connect your AI (on ContentIn Growth or Pro: Profiles → Connections). In n8n, add an MCP Client node, set the transport to HTTP Streamable, use the server URL as the endpoint and add a Header Auth credential with the name X-MCP-Key and your key as the value. The tools then show up for your workflow or AI Agent node. Each key acts for one ContentIn profile.

Does it post without asking me?

No. Every post is confirmed by you. Scheduling and publishing are two-step: the tool returns the exact text and a confirmation token, and the post only goes out once you have confirmed that text. Automations are good for gathering analytics and leads, saving material and producing drafts; the last step stays with you.

Is it LinkedIn-safe? Does it use the official API?

Yes. Posting and post analytics go through LinkedIn's official API for the LinkedIn account you connected to ContentIn. Your agent never logs into your LinkedIn account, and your LinkedIn password and cookies never reach ContentIn or your agent.

Do I need to write prompts or configure the tools?

No. Once connected, you ask in plain language and your agent picks the right tool. There's no system prompt to write. If something is missing, your agent can call get_account_status to see your setup, your plan and what each tool needs. If you build your own agent or workflow, the tool descriptions come with the server.

I run several profiles or an agency. How does that work?

Agent and Agent Pro are priced per LinkedIn profile. Each connection or API key is bound to one profile, which you pick when you connect, so each client's voice, material and queue stay separate.

What is coming next?

Four tools are coming in Q4 2026, and none of them is available today. In Agent and Agent Pro: search your own posts and comment from your AI. In Agent Pro only: viral post library search and engage with your leads. They ship once OpenAI and Anthropic have finished reviewing the current version. Draft check, webhooks and sending leads to your CRM are not planned yet; we build them in the order people ask for them, and the “I want this” buttons on this page are how we count that.

What happens to my data?

A connected agent can only reach the one ContentIn profile you approved: its posts, drafts, ideas, analytics, comments and leads. It can't see your other profiles, your billing details or your LinkedIn password. You can see and revoke every connection and API key on the ContentIn for Agents page (on ContentIn Growth or Pro: Profiles → Connections), and revoking takes effect immediately. What your agent does with data it reads is governed by that agent's own terms.

Keep your agent. Make it write like you.

Connect your agent with one URL and it schedules and publishes your LinkedIn posts, up to 2 posts a day and 30 a month, free. Add a plan for your analytics, your saved material and ContentIn's writing, from $29 a month, or $276 a year.
