Bluesky MCP server

Post to Bluesky from Claude

Claude cannot reach Bluesky by itself. Connect Blotato's MCP server once and it can publish posts, threads, image posts to Bluesky from a plain prompt. One hosted endpoint, no developer app, no copy-paste.

This one publishes. Search "Bluesky MCP server" and you get two different kinds of tool: scrapers that read public Bluesky data, and publishers that put a post live on your own account. Blotato is the second kind, on Bluesky's official API, not browser automation.

How to post to Bluesky with Claude

Connect your Bluesky account. Sign in to Blotato and connect Bluesky through the normal login flow. Blotato holds the tokens and refreshes them, so this is the last time you think about auth.
Add the MCP server to Claude. In Claude, open Settings, then Connectors, then add a custom connector pointing at https://mcp.blotato.com/mcp. Claude Code and Cowork take the same URL.
Ask Claude to post. Write it the way you would say it out loud: "Cross-post my last X thread to Bluesky." Claude calls the publish tool and Blotato puts the post live.

On Bluesky, Blotato covers publishing and scheduling and analytics. It does not yet cover comments and direct messages on this platform, so if that is what you need, this is the wrong tool and it is better you know now.

What it looks like in practice

Screenshots from the full Bluesky walkthrough, showing the connection and a real published post.

The Blotato MCP server connected in Claude Code — The same hosted endpoint reaches Bluesky.

Claude publishing a post to Bluesky through Blotato — No AT Protocol facets to build by hand.

The published post live on Bluesky — Live on Bluesky from a plain-language prompt.

Why not just build it against the Bluesky API?

Bluesky runs on AT Protocol rather than a conventional REST API, so rich text, links, and image embeds have to be constructed as facets instead of just being included in the text.

You can absolutely build it yourself, and if Bluesky is the only network you will ever post to, that is a reasonable call. The trade shows up at the second platform: every network has its own auth model, its own upload flow, and its own review process, and they change on their own schedules. Blotato is one endpoint across nine of them, at a flat price that does not move when you post more.

If you would rather own that layer yourself, we wrote up the honest tradeoff between open-source and managed posting APIs, and our roundup of social media MCP servers covers the alternatives, including the ones that only draft rather than publish.

Who is already running this

These are Blotato customers describing their own agent and API setups, in their own words.

I'm building an AI startup focussing on educational content in social media (eventually) and experimenting with a lot of things right now. Blotato as a platform is incredibly easy to use, has a great API for our needs and great pricing. The best part is the openness of the platform: all other platforms we tested continuously limit you and try to pry more money out of you for little value. Blotato is the opposite: open and offering incredible power.

What I like about Blotato is that it's a tool that removes creative bottlenecks, particularly its API features. Blotato turns you into a content machine, like, content creation on a steroids. I'm very happy that I came across this tool on YouTube. Now, I don't have to worry about publishing anymore. If you're looking for an affordable API solution or mass content production and publishing, Blotato is worth a try.

FAQ

Bluesky MCP server FAQs

01 Can Claude post to Bluesky?

Yes. Claude cannot reach Bluesky on its own, but connecting an MCP server gives it the tools to publish. Add Blotato's server at https://mcp.blotato.com/mcp, connect your Bluesky account once, then ask Claude to post in plain language.

02 What is a Bluesky MCP server?

It is a Model Context Protocol server that exposes Bluesky actions as tools an AI assistant can call. Instead of you describing the Bluesky API to Claude, the server hands Claude a publish action it can invoke directly.

03 Do I need Bluesky API access or a developer app?

No. Blotato holds the platform integration and the OAuth tokens, so you connect your account through a normal login flow instead of registering a developer app. Bluesky runs on AT Protocol rather than a conventional REST API, so rich text, links, and image embeds have to be constructed as facets instead of just being included in the text.

04 Can Claude schedule Bluesky posts for later?

Yes. Ask for a time and Blotato queues the post and publishes it then. You do not need Claude open at the scheduled moment.

05 What else can Blotato's MCP server do on Bluesky?

06 Does this Bluesky MCP server publish, or only read Bluesky data?

It publishes. This matters because "Bluesky MCP server" returns two different kinds of tool: scrapers that read public Bluesky data for analysis, and publishers that put a post live on your own account. Blotato is the second kind, built on Bluesky's official API rather than scraping, so your agent finishes the job instead of handing you a draft.

07 Does this work with Claude Code and Cowork too?

Yes. It is one hosted endpoint, so anything that speaks MCP can use it: Claude Desktop, Claude Code, Cowork, and other MCP clients. The same server also covers the other eight platforms, so one connection handles your whole posting surface.

08 How much does it cost?

Blotato starts at $29/mo flat for 20 connected accounts, and the price does not move with your posting volume. Note that API and MCP access is not part of the 7-day trial: generating a key starts the paid Starter plan, so plan on subscribing rather than trialing it.

The same connection covers eight more platforms

Bluesky is one target on the same endpoint. Once Claude is connected, it can publish to the rest without any further setup.
