What is a social media MCP server?

A social media MCP server gives an AI client tools to read social platforms during a conversation. PostToData's server at https://posttodata.com/mcp exposes read-only tools for public posts, comments, profiles and available captions. Supported clients sign in through OAuth; API keys remain available for code. Both use the same prepaid balance.

Real API calls require verification for one trial, or a signed-in account with prepaid credit.

From code

curl

curl "https://posttodata.com/v1/bluesky/user?username=bsky.app&limit=5" -H "Authorization: Bearer YOUR_API_KEY"

Python

import requests

r = requests.get(
    "https://posttodata.com/v1/bluesky/user",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    params={"username": "bsky.app", "limit": 5},
)
for item in r.json()["data"]["items"]:
    print(item["url"], item.get("text") or item.get("title"))

From your AI

Claude and ChatGPT clients that support OAuth can sign in without pasting a key. Follow the client setup guide. The command below is the API-key option for Claude Code.

Add the MCP server once

claude mcp add --transport http posttodata https://posttodata.com/mcp --header "Authorization: Bearer YOUR_API_KEY"

Then ask

“Look up the bsky.app account on Bluesky and tell me how many followers it has and what it posted most recently.”

The model calls get_user with platform bluesky.

Good to know

It uses the Streamable HTTP transport, so there is nothing to install or run locally.
All tools are read-only.
Call list_platforms to see which platforms are live and what each call costs.
