Replit Agent Social Media MCP Setup

Replit Agent connects to a social media MCP server by adding it as a custom integration by URL, rather than by pasting a JSON config file. Add https://mcp.blotato.com/mcp as a custom MCP server in Replit Integrations, and Agent fetches the tool list automatically and makes it available across all your projects.

How to connect Replit Agent to social media

  1. Connect your social accounts in Blotato and copy your API key from Settings then API.
  2. In Replit, open Integrations and choose to add a custom MCP server, since Blotato is not in the pre-listed catalog.
  3. Set the base URL to https://mcp.blotato.com/mcp and supply your API key.
  4. Mention the server in an Agent chat. Agent fetches the tool list and picks the right tool for the request.

How do I know it worked?

Ask Replit Agent 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 only return data for X, Instagram, Facebook, Threads, and Bluesky. The other four platforms publish normally but report no metrics yet.

What breaks, and how to fix it

The thing to know on Replit is that Agent asks for confirmation before running a tool that needs it, so a publish can sit waiting on a prompt rather than failing outright. If a post has not appeared, check for a pending confirmation in the chat before re-checking the connection. Blotato is also not in the pre-listed catalog, so use the custom-server path rather than looking for it by name.

What is different about Replit Agent

Replit connects MCP servers at the account level rather than per project, so a server added once is available across every project you build, and Agent fetches the tool list itself instead of you declaring tools. It is also the only client here with a shareable install link, which encodes the server name and base URL into a one-click Add to Replit badge.

FAQ

Replit Agent social media FAQs

01 Can Replit Agent post to social media?
Yes. Replit Agent 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. Replit Agent authenticates with api key header.
02 How do I connect Replit Agent to social media?
Replit Agent connects to a social media MCP server by adding it as a custom integration by URL, rather than by pasting a JSON config file. Add https://mcp.blotato.com/mcp as a custom MCP server in Replit Integrations, and Agent fetches the tool list automatically and makes it available across all your projects.
03 How do I set up Replit Agent for social media?
Setting up Replit Agent for social media takes one connection. Connect your social accounts in Blotato, then give Replit Agent the hosted MCP endpoint https://mcp.blotato.com/mcp and authenticate with api key header. For Replit Agent specifically that means: custom mcp server, added by url in integrations. Once it loads, Replit Agent 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 Replit Agent?
Let Replit Agent do the drafting and decision making, and let a publishing layer hold the accounts and the schedule. The thing that makes this work on Replit Agent in particular: Replit connects MCP servers at the account level rather than per project, so a server added once is available across every project you build, and Agent fetches the tool list itself instead of you declaring tools. It is also the only client here with a shareable install link, which encodes the server name and base URL into a one-click Add to Replit badge.
05 What goes wrong when connecting Replit Agent?
The thing to know on Replit is that Agent asks for confirmation before running a tool that needs it, so a publish can sit waiting on a prompt rather than failing outright. If a post has not appeared, check for a pending confirmation in the chat before re-checking the connection. Blotato is also not in the pre-listed catalog, so use the custom-server path rather than looking for it by name.
06 Does Replit Agent need to be running for a scheduled post to go out?
No. Scheduling runs on Blotato rather than inside Replit Agent. Once the agent queues a post, it publishes at the scheduled time whether or not Replit Agent, your terminal, or your laptop is on. This is the practical difference between an agent that drafts and a system that runs unattended.
07 Do I need a developer app or platform API keys to use Replit Agent this way?
No. Blotato holds the platform integrations and manages the OAuth tokens, including refreshes. You connect each social account through a normal login flow instead of registering your own app on every network and waiting for review. Replit Agent never handles a platform credential.
08 What can Replit Agent not do on social media?
Publishing and scheduling cover all nine platforms, but the rest is uneven and worth knowing before you build against it. Analytics covers X, Instagram, Facebook, Threads, and Bluesky. Comments and direct messages cover Instagram and Facebook. Keyword-triggered DM automation is not available at all. None of that varies by agent: it is the same surface whichever client you connect.
09 How much does it cost to connect Replit Agent?
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.
