Octopost + Claude Desktop
Octopost is a social media MCP server. Add it to Claude Desktop and your agent can post to X, write native threads, schedule posts and hold them for your approval. Octopost is live on X; other networks are on the roadmap.
1. Start a plan and connect X
Sign up (7 days for $1, then $29 a month), then connect your X account on the accounts page.
2. Add Octopost to Claude Desktop and sign in
Settings > Connectors > Add custom connector (the same list as claude.ai).
https://octopost.ink/mcp- Open Settings > Connectors, choose Add custom connector, name it Octopost and paste https://octopost.ink/mcp.
- Click Connect. An Octopost page opens: sign in if asked, check the account, and click Allow.
- In a chat, click + below the message box, then Connectors, and switch Octopost on.
No key to copy: Claude Desktop signs in to Octopost (OAuth) and stays connected.
3. Try it
Ask your agent:
- “List my Octopost accounts.”
- “Queue a post to X about today's release and hold it for my approval.”
- “Turn these release notes into a 3-post X thread and schedule it for 9am tomorrow.”
If it doesn't connect
- The sign-in window didn't open, or it says the app isn't registered: remove the Octopost connector and add the URL again.
- 401 Unauthorized with a key: the key is missing, mistyped, revoked, or not sent as
Authorization: Bearer op_.... The error message names which. - “Your Octopost plan is not active”: finish the $1 trial checkout on the billing page.
- “No twitter account connected”: connect X on the accounts page.
