ChatGPT can't post to LinkedIn by itself, and LinkedIn's own app in ChatGPT looks people up rather than posting. On ChatGPT Business, Enterprise or Edu, you can add Postel as a custom MCP server: ChatGPT then drafts LinkedIn posts in your voice and schedules them to your personal LinkedIn profile after you confirm.

Draft a LinkedIn post about what we shipped this week: CSV export and faster search. Three customers asked for them on calls.

We shipped two small things this week, and both came from customer calls.
CSV export now works from any view. Search answers before you finish typing.
Three customers told us on calls where they lost time each week, so we fixed that first. If something feels slow to you, reply and tell me.

Not without help. What exists today (checked October 30, 2026):
LinkedIn's app in ChatGPT is for lookups.OpenAI's listing describes it as a way to "look up any professional on LinkedIn without leaving ChatGPT". It lists no way to write, schedule or publish posts.
A custom MCP server can post. ChatGPT can connect to tools built on the Model Context Protocol (MCP). Postel's server gives it tools to draft, schedule and publish LinkedIn posts.
Your ChatGPT plan decides whether you can add one. Custom servers that make changes, like posting, work on Business, Enterprise and Edu.
ChatGPT plan
Can it add Postel?
Business
Yes. Admins and owners add it for the workspace
Enterprise and Edu
Yes. Admins add it, or members with the "Create plugins with MCPs" permission
Pro
No. Pro can only connect custom servers that read, so ChatGPT can't save or schedule a post
Plus, Go and Free
No. OpenAI doesn't list custom MCP servers for these plans
Step 1: Create a Postel account and connect LinkedIn
Sign up for Postel and connect your LinkedIn profile under Settings > Channels. LinkedIn asks you to approve the connection on its own consent screen.
Step 2: Add Postel in ChatGPT
In ChatGPT on the web, open Plugins, click + and choose Add custom MCP server. Name it Postel and paste this under Connection:
Server URL
https://www.postel.app/api/mcp
Choose OAuth for sign-in, read the risk warning, tick I understand and want to continue and click Create as a plugin. You don't need to turn on developer mode.
Step 3: Sign in to Postel
A Postel window opens. Sign in and approve access. ChatGPT never sees your LinkedIn password; Postel holds the LinkedIn connection.
Step 4: Ask for a LinkedIn post
Start a chat and ask: "Use Postel to draft a LinkedIn post about what we shipped this week." Postel writes the post in your voice and saves it as a draft. Ask for changes, then say when to schedule it.
ChatGPT can ask you to confirm before Postel schedules or publishes. Whether it does depends on the plugin's permission setting; set Postel to Always ask to confirm every action (OpenAI on permissions).
What to ask ChatGPT
"Draft a LinkedIn post about the client project we finished this week. Keep it under 1,200 characters."
"Turn these notes into a LinkedIn post: [paste]. Put the link in the first comment."
"Make the first two lines stronger."
"Schedule it for Tuesday at 8:30am New York time."
"What do I have scheduled on LinkedIn next week?"
"Write Monday, Wednesday and Friday's posts from this transcript and schedule them at 9am."

On ChatGPT Plus or Pro?
You can't add a server that posts on those plans, but you still have two good options:
Write in ChatGPT, schedule in Postel. Paste the draft into Postel's editor, or let Postel write it from your idea in the voice it learned from your LinkedIn posts. See how to write LinkedIn posts with ChatGPT.
Use Claude for this one job. Claude's free plan can add one custom connector, and Postel is in Claude's connector directory. See how to connect Claude to LinkedIn.
ChatGPT's agent can also operate a website in a browser on paid plans, but it stops for you to sign in and some sites block automated browsers, so it's a slow way to post every week.
Draft and schedule LinkedIn posts from ChatGPT, in your own voice
Postel learns how you write, drafts posts in your voice and publishes them to X, LinkedIn, Bluesky and Mastodon on schedule. Use it on its own or from Claude, ChatGPT or Cursor.

Frequently asked questions
Updated Oct 30, 2026.
Can ChatGPT post on LinkedIn for me?
Yes, with a custom MCP server such as Postel on ChatGPT Business, Enterprise or Edu. ChatGPT drafts the post, you confirm, and Postel schedules or publishes it to your personal LinkedIn profile.
Does LinkedIn have an official ChatGPT app?
Yes, but it's for looking up people: their title, company, location and follower count. As of October 30, 2026, OpenAI's listing describes nothing for writing or posting.
Can ChatGPT Plus connect to LinkedIn?
Not with a server that posts. OpenAI lists custom MCP servers for Business, Enterprise and Edu, and read-only servers for Pro. On Plus, write in ChatGPT and schedule in Postel, or use Claude's free plan with Postel's connector.
Does it work in the ChatGPT phone app?
You add the server on ChatGPT on the web. OpenAI says custom MCP servers can't be connected from mobile.
Is it safe to connect ChatGPT to my LinkedIn?
ChatGPT never gets your LinkedIn password. Postel publishes through LinkedIn's official API with the permission you grant on LinkedIn's consent screen, and you can remove that access in your LinkedIn settings at any time.
Can ChatGPT read my LinkedIn messages?
Not through Postel. It covers drafting, scheduling and publishing your own posts.
$1 for 7 days, then from $29 a month. Cancel anytime. The MCP server is included in every Postel plan. Scheduling and publishing need a paid plan or the trial. Postel writing a post uses 1 AI credit; saving text ChatGPT wrote uses none.
