The Bluesky MCP from Hermoso is a hosted MCP server: connect Bluesky once and Claude, ChatGPT, Cursor or any other assistant you use can work in your Bluesky account for you. It is the same connection the Hermoso app uses, so you sign in once, and Bluesky sits next to the rest of the marketing Hermoso runs on autopilot for you.

Works wherever you already chat
It is one account, not one per app. Schedule something from Cursor and it shows up in your Hermoso calendar; draft a reply in Claude and it goes out from the same profile.

Frequently asked questions
Can an AI agent post to Bluesky through Hermoso?
Yes. The Bluesky surface is exposed over one OAuth'd MCP endpoint, so Claude, ChatGPT, Cursor, Codex, Cline and the CLI can all drive it once the account is connected.
Do I need a separate Bluesky connection for the app and for MCP?
No. One authorisation covers the web app, the MCP server and the CLI. It is the same stored connection.
What is the Bluesky MCP server URL?
https://app.hermoso.ai/mcp. It is one hosted server for every channel Hermoso connects to, so there is no separate Bluesky server to install. Add it to your assistant as a custom connector and sign in with OAuth; no key to paste.
