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