# Bluesky MCP Server: Post to Bluesky from Claude or ChatGPT **Source:** https://posteverywhere.ai/mcp/bluesky --- AT Protocol # Bluesky MCP Server **PostEverywhere runs a hosted MCP server at `https://mcp.posteverywhere.ai`, and Bluesky is one of the 11 platforms it publishes to.** A Bluesky MCP server lets an AI assistant publish to Bluesky over the AT Protocol, so you can schedule posts from Claude, ChatGPT or any MCP client. Connect the account once and describe what you want posted. Bluesky is the most developer-friendly platform we support, because the AT Protocol is open and its API is genuinely public rather than gated behind an application process. That makes it the easiest of the eleven to automate, and a sensible first platform if you are testing what an AI assistant can actually do with a social account. It is included on every plan from [$29/mo](https://posteverywhere.ai/pricing), alongside the [REST API](https://posteverywhere.ai/social-media-api). If you would rather schedule Bluesky from a dashboard, that is our [Bluesky scheduler](https://posteverywhere.ai/bluesky-scheduler). ## Connect it to your assistant One URL, no separate Bluesky credentials to manage. Connect the server once and every platform you have authorised, including Bluesky, becomes available to the assistant.

One instruction covers both, with copy tuned per platform. ### No approval process Unlike TikTok or Instagram, there is no application to be granted before scheduling works. Connect the account and it publishes. ### Draft for approval Hold the post for a human to read before it goes out, the same as every other platform on the server. ## What you actually type No commands or syntax. You describe the outcome and the assistant calls the tools: “Write a Bluesky post about our MCP server for people who want their AI assistant to schedule social posts, keep it short and plain, and schedule it for 10am tomorrow. Post the same idea to X in a tighter form.” ## Bluesky specifics worth knowing ### The most open API of the eleven The AT Protocol is public and open, so there is no application or approval gate. If you want to see what agent-driven posting feels like before committing, Bluesky is the least friction. ### Keep it short Bluesky posts are short-form like X, so ask for a compact variant rather than reusing LinkedIn copy. ### Cross-post, do not duplicate The Bluesky and X audiences overlap heavily. Posting identical text to both reads as automation, so ask for a different phrasing on each. ## Bluesky MCP server FAQs ### What is a Bluesky MCP server?
