How to Connect Claude to Social Media

Claude.ai connects to social media through a custom connector. Add Blotato at mcp.blotato.com/mcp under Customize then Connectors, approve the OAuth prompt, and Claude can publish and schedule to nine platforms from the same chat window you already draft in. There is no API key to paste on this surface: Claude.ai authenticates over OAuth.

How to connect Claude.ai to social media

Connect your social accounts once in Blotato, so the agent never touches a platform credential.
In Claude.ai, open Customize, then Connectors, then the plus button, then Add custom connector.
Name it Blotato and set the URL to https://mcp.blotato.com/mcp.
Press Connect and approve access. You must be logged into Blotato in the same browser for the OAuth handshake to complete.

Connector URL (no JSON, no key)

https://mcp.blotato.com/mcp

Blotato added as a custom connector at mcp.blotato.com/mcp, with its social media tools listed — Blotato as a custom connector, with its tool permissions listed. This is the screen Claude.ai shows once the OAuth approval completes.

How do I know it worked?

Ask Claude.ai to list your connected accounts. It calls blotato_list_accounts and returns your platforms, which confirms both the connection and the authentication in one step. If you see your accounts, setup is done.

First prompt to run

What social media accounts do I have connected?

An AI agent answering "what social accounts do i have connected?" by calling Blotato and listing 10 connected social media accounts across Twitter, Bluesky, Instagram, Threads, LinkedIn, Facebook, YouTube, Pinterest, and TikTok — The reply you are looking for: the agent calls Blotato and lists every connected account. Here it returns 10 accounts across all nine platforms.

Worth knowing before you rely on it: analytics prompts return data for every platform except LinkedIn, which publishes normally but reports no metrics yet.

What to ask Claude.ai once it is connected

Take the post we just wrote and put it on LinkedIn and X.: Claude calls blotato_list_accounts to find the two accounts, then blotato_create_post once per platform with the text already in the conversation. Nothing gets retyped or pasted between windows.
Schedule that for Tuesday at 9am instead.: The same blotato_create_post call carries a scheduledTime, so the post sits in Blotato's queue. Closing the browser tab does not affect it.
Which of my posts did best last month?: blotato_list_top_posts returns ranked posts for every platform except LinkedIn, which publishes normally but returns no metrics yet. Ask about a LinkedIn post's numbers and Claude has nothing to read.
Someone in my Instagram DMs is asking whether we ship to Canada. Pull up that thread and answer it.: blotato_list_conversations finds the thread, blotato_get_conversation and blotato_list_messages read that exchange rather than the whole inbox, and blotato_send_message sends your reply. Meta closes the reply window 24 hours after their last message, so an old thread can be readable and no longer answerable.

What breaks, and how to fix it

The failure specific to Claude.ai is a connector that shows Connected while every tool call returns an OAuth error. That is not a bad key, it means the Blotato subscription is not active: API access requires a paid plan, so generate a key in Settings then API to activate it. On a Claude Team or Enterprise plan there is a second trap, since only a workspace admin can add custom connectors at all.

What is different about Claude.ai

Claude.ai is the only surface here where you cannot fall back to an API key header. Anthropic does document request-header auth for custom connectors, but it is in beta behind early access and the allowed header names are a reviewed allowlist of authorization, x-api-key, and x-auth-token. The header Blotato authenticates with is not on that list, so OAuth is the only path that works today.

Vendor documentation: Claude.ai MCP setup. The handshake it uses is the MCP authorization spec, which Blotato implements in full, including dynamic client registration and PKCE.

FAQ

Claude.ai social media FAQs

01 Can Claude.ai post to social media?

Yes. Claude.ai cannot reach a social account on its own, because it has no platform credentials. Connecting it to Blotato's hosted MCP server at https://mcp.blotato.com/mcp gives it tools to publish and schedule across nine platforms: X, LinkedIn, Facebook, Instagram, TikTok, YouTube, Threads, Bluesky, and Pinterest. Claude.ai authenticates with oauth.

02 How do I connect Claude.ai to social media?

03 How do I set up Claude.ai for social media?

Setting up Claude.ai for social media takes one connection. Connect your social accounts in Blotato, then give Claude.ai the hosted MCP endpoint https://mcp.blotato.com/mcp and authenticate with oauth. For Claude.ai specifically that means: connector url (no json, no key). Once it loads, Claude.ai can publish and schedule to X, LinkedIn, Facebook, Instagram, TikTok, YouTube, Threads, Bluesky, and Pinterest from a plain-language prompt.

04 What is the best way to manage social media with Claude.ai?

Let Claude.ai do the drafting and decision making, and let a publishing layer hold the accounts and the schedule. The thing that makes this work on Claude.ai in particular: Claude.ai is the only surface here where you cannot fall back to an API key header. Anthropic does document request-header auth for custom connectors, but it is in beta behind early access and the allowed header names are a reviewed allowlist of authorization, x-api-key, and x-auth-token. The header Blotato authenticates with is not on that list, so OAuth is the only path that works today.

05 What goes wrong when connecting Claude.ai?

06 Does Claude.ai need to be running for a scheduled post to go out?

No. Scheduling runs on Blotato rather than inside Claude.ai. Once the agent queues a post, it publishes at the scheduled time whether or not Claude.ai, your terminal, or your laptop is on. This is the practical difference between an agent that drafts and a system that runs unattended.

07 What can I ask Claude.ai to do once it is connected?

"Take the post we just wrote and put it on LinkedIn and X." Claude calls blotato_list_accounts to find the two accounts, then blotato_create_post once per platform with the text already in the conversation. Nothing gets retyped or pasted between windows. "Schedule that for Tuesday at 9am instead." The same blotato_create_post call carries a scheduledTime, so the post sits in Blotato's queue. Closing the browser tab does not affect it. "Which of my posts did best last month?" blotato_list_top_posts returns ranked posts for every platform except LinkedIn, which publishes normally but returns no metrics yet. Ask about a LinkedIn post's numbers and Claude has nothing to read. "Someone in my Instagram DMs is asking whether we ship to Canada. Pull up that thread and answer it." blotato_list_conversations finds the thread, blotato_get_conversation and blotato_list_messages read that exchange rather than the whole inbox, and blotato_send_message sends your reply. Meta closes the reply window 24 hours after their last message, so an old thread can be readable and no longer answerable.

08 How much does it cost to connect Claude.ai?

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

Connecting a different agent?

Same endpoint, same accounts, one setup per client. The AI agents for social media hub covers what all of them share, including every tool your agent can call.
