LinkedIn Pilot

ChatGPT App / MCP server by SDK Enterprises for publishing to personal LinkedIn accounts.

MCP tools

• linkedin_auth_status
• linkedin_publish_post
• linkedin_publish_image_post
• linkedin_schedule_post
• linkedin_schedule_image_post
• linkedin_list_scheduled_posts
• linkedin_cancel_scheduled_post

Publish tools return the LinkedIn post ID and a usable post URL.

LinkedIn access

The app uses LinkedIn OAuth with openid, profile, email, and w_member_social. Never commit the LinkedIn client secret or user tokens.

Scheduling

Scheduled posts are stored in the encrypted service store and dispatched through QStash at the requested time. Required production variables:

• PUBLIC_BASE_URL=https://linkedin.sdk.enterprises
• QSTASH_TOKEN
• SCHEDULER_DISPATCH_SECRET

The QStash free tier supports delays up to 7 days; longer delays require a paid QStash plan.

Public routes

• / — product landing page
• /privacy — privacy page
• /terms — terms page
• /health — health check
• /mcp — authenticated MCP endpoint

Local run

pnpm install
cp .env.example .env
pnpm dev

Architecture

ChatGPT authenticates to this MCP server through OAuth 2.1 + PKCE. The server delegates account authorization to LinkedIn and isolates sessions by the authenticated LinkedIn member. Scheduled delivery uses a private authenticated callback and idempotent schedule records.
