Frequently asked questions
What is the Bluesky MCP server?
It's the HubPost MCP server used with your Bluesky account. Connect it to Claude, ChatGPT, Cursor or any MCP client and your agent can draft, schedule and publish Bluesky posts through HubPost. It's built by HubPost, not by Bluesky.
Can Claude post to Bluesky?
Yes. Add HubPost to Claude from the Claude directory, or with one command in Claude Code, then sign in and ask Claude to schedule or publish your next post on Bluesky.
Can ChatGPT post to Bluesky?
Yes. Add the HubPost app in ChatGPT, sign in, and mention @HubPost when you ask it to draft, schedule or publish posts on Bluesky.
What can my agent post on Bluesky?
Bluesky posts, photos, and videos, with text up to 300 characters.
Can my agent see my Bluesky analytics?
Yes. For each published Bluesky post your agent can read the numbers Bluesky reports, such as views, comments and shares, including posts you published in the Bluesky app. Ask which posts did best and plan the next ones around them.
What do I need to connect Bluesky?
You need a HubPost account and a Bluesky account and an app password. Connect it in HubPost, then add the MCP server to your agent and sign in.
Can my agent change Bluesky posts that are already live?
No. Your agent can edit, reschedule or delete drafts and scheduled posts, but once a post is published on Bluesky it can't be changed or removed from HubPost.
Will my agent post without asking me?
Most AI clients ask you to approve each tool call before it runs. You can also ask for drafts instead of scheduled posts: a draft never goes out until you schedule it.
Is the Bluesky MCP free?
Yes. The MCP server is included in every HubPost plan, including the free plan. Plan limits, such as how many accounts you can connect, apply the same way as in the app.
