Gemini + CatCaster
Google Gemini with remote MCP
Gemini can plan and write; CatCaster executes publishing on the channels you already connected—same MCP URL as every other client.
Example chat
via CatCaster MCP · Gemini
How to connect Gemini
- In a Gemini product that supports MCP connectors, add the CatCaster MCP URL as a custom server.
- Complete CatCaster OAuth when the client prompts for authorization.
- Confirm tools/list returns CatCaster tool names before relying on the connection.
- If MCP is unavailable in your Gemini edition, use Claude or Cursor with the same server URL instead.

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.

Channels agents can reach
Example prompts
- List knowledge items about our pricing and draft an X post that cites only approved facts.
- Show connected channels and which ones support video placements.
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.
