AI agent
ChatGPT + CatCaster
Plan and schedule from the browser
Turn ChatGPT into a scheduling copilot: it discovers your connected channels, writes platform-native copy, and queues posts in CatCaster while you stay in the chat.
Example chat
via CatCaster MCP · ChatGPT
How to connect ChatGPT
- On chatgpt.com (web), enable Developer mode under Settings → Security and login if you use a custom MCP connector.
- Open Settings → Connectors → Add connector, paste the CatCaster MCP URL, and save.
- When ChatGPT connects, complete CatCaster sign-in and approve workspace access in the browser.
- In a new chat, enable the CatCaster connector and ask to list channels before scheduling anything.

OAuth sign-in is recommended. Developer API keys in Settings → Developer work for clients that cannot open the browser consent flow. Keep a human in the loop before publish_post and send_inbox_reply.
What you can do with ChatGPT
Week-ahead calendar
Ask for a content plan across your channels; the agent validates each draft and schedules only after you confirm times.
Launch announcements
Ship coordinated posts to X and LinkedIn with different hooks, using get_brand_context so tone matches your workspace.
Draft-only mode
Keep everything in create_post and validate_post until you are ready—no publish_post until you say so.
Performance check-ins
Pull get_analytics and list_published_content to summarize what worked last week before planning the next.
Channels agents can reach
Example prompts
- List my connected channels and draft three Instagram captions from this bullet list. Do not schedule until I pick one.
- Review new content proposals in my workspace and summarize which ones fit our launch theme.
Agents should run validate_post and show drafts before scheduling or publishing. CatCaster MCP does not generate images or video—attach media the agent already has via upload_media or HTTPS URLs on create_post.
Frequently asked questions
- Is CatCaster preinstalled in ChatGPT or Claude?
- No. You add CatCaster as a custom MCP connector (or use OAuth from a client that supports remote MCP). Sign in with your CatCaster account when the client opens the consent flow.
- Will the agent publish without asking me?
- CatCaster expects a human in the loop. Agents should run validate_post and show drafts before schedule_post or publish_post. Inbox send_inbox_reply should only run after you explicitly approve the draft.
- Can agents generate images or video inside MCP?
- Not through CatCaster MCP today. Agents can attach media they already have via upload_media (HTTPS URL) or URLs on create_post. Image and video generation in the product UI is separate from MCP.
- What platforms can agents reach?
- Any channel already connected in your workspace—Instagram, Facebook, Threads, TikTok, LinkedIn, X, YouTube, Pinterest, and your CatCaster blog, subject to each platform’s API limits documented on our platform guides.
