Call a tool from your agent

JSON
{
  "tool": "social_api_list_post_comments",
  "arguments": { "account_id": "acc_...", "inbox_post_id": "17895695668004550", "limit": 20 }
}

{
  "tool": "social_api_send_dm",
  "arguments": { "account_id": "acc_...", "conversation_id": "7f1c4e2b-...", "text": "Thanks for reaching out!" }
}

{
  "tool": "social_api_reply_to_review",
  "arguments": { "account_id": "acc_...", "review_id": "sapi_rev_...", "text": "We appreciate the feedback." }
}

// Each tool returns the same normalized JSON for every platform.

Your agent calls SocialAPI.ai tools by name with typed arguments. The same MCP server exposes reading, messaging, and publishing across every connected network.

Why: AI agents need tools, not OAuth boilerplate.

Calling each network's native API means a developer app and an app review per platform, an OAuth flow per platform, its own rate limits, and a different payload for every network, all before the agent can answer a single comment. A unified social media API does that work once: the agent gets one typed toolset and one JSON shape for every network, so you spend your time on the agent's behavior instead of platform plumbing.

Where it lands: One call, every network

The same request lands on each platform as that platform draws it.

In depth: Social Media API for AI Agents, in depth

How an AI agent publishes and replies

Add the hosted server at https://api.social-api.ai/mcp to your agent's MCP host and sign in once over OAuth 2.1, or pass an API key. The agent calls social_api_list_accounts to see the connected brands, then social_api_create_post to publish, social_api_list_post_comments and social_api_reply_to_comment to work the comments, and social_api_send_dm to answer messages. Every tool returns the same JSON shape on every network, so one prompt works for Instagram, TikTok, and LinkedIn alike.

Typed tools for every capability

Publishing, comments, DMs, mentions, reviews, analytics, webhooks, media upload, and exports are each exposed as a typed tool, 75+ in total, with clear arguments and annotation hints. The agent sees exactly what each tool does and what it returns, which keeps tool selection accurate and reduces malformed calls.

Works with Claude, ChatGPT, Cursor, and Codex

The server runs in any Model Context Protocol host: Claude and Claude Code, ChatGPT, Cursor, Codex, and open-source agent runtimes. Connect it once per host and every social capability becomes available to that agent. Setup steps for each host are in the integrations guide at https://docs.social-api.ai.

Validation before anything goes live

An agent can check a draft with social_api_validate_post before publishing it. The tool reports each platform's limits the draft breaks, such as caption length or media format, so the agent fixes the post instead of finding out from a failed publish.

Analytics the agent can learn from

social_api_get_post_analytics and social_api_get_account_analytics return post and account metrics on the platforms that report them. An agent can read last week's results before drafting this week's posts, so the content loop closes inside the agent instead of in a spreadsheet.

Listed on MCP marketplaces

SocialAPI.ai is published on the major MCP marketplaces, including Smithery, Composio, MCP.so, and PulseMCP, so developers and agents can discover and install it through the catalogs they already use.

Compare: Compared to other social media MCP servers

Most social media MCP servers publish and schedule. Fewer can read and reply to comments, DMs, reviews, and mentions, and only a few connect over OAuth 2.1 without a pasted key. See how SocialAPI.ai ranks against Zernio, Upload-Post, Ayrshare, Buffer, and the rest.

Frequently asked questions

What developers ask before they ship.

What is a social media API for AI agents?

A social media API for AI agents is an API that exposes social actions, such as publishing posts, reading comments, and sending DMs, as tools an AI agent can call directly, usually through a Model Context Protocol (MCP) server. The agent connects once and gets the same tools on every network, instead of a separate integration per platform.

What is the best social media API for AI agents in 2026?

For agents that have to answer people, SocialAPI.ai: its MCP server covers publishing plus comments, DMs, mentions, and Google Business Profile reviews on 13 platforms, connects over OAuth 2.1, and bills a flat price per brand. Zernio has more tools and networks but bills per connected account, Upload-Post is cheaper but has no mention tools, and Ayrshare's MCP server accepts API keys only.

How does an AI agent post and reply through SocialAPI.ai?

Connect the MCP server at https://api.social-api.ai/mcp in your agent's host, then the agent calls tools by name: social_api_create_post to publish, social_api_list_post_comments and social_api_reply_to_comment for comments, social_api_send_dm for messages, and social_api_reply_to_review for Google reviews. Each call takes typed arguments and returns the same JSON on every platform.

Can I use it in Claude Code, Cursor, or ChatGPT?

Yes. The SocialAPI.ai MCP server works with any Model Context Protocol host, including Claude, Claude Code, ChatGPT, Cursor, and Codex. It is also listed on Smithery, Composio, MCP.so, and PulseMCP, so you can install it through the catalog you already use.

Do I need my own Meta, TikTok, or Google developer app?

No. Instagram, Facebook, Threads, TikTok, YouTube, LinkedIn, and Google Business Profile accounts connect through SocialAPI.ai's approved apps, so there is no app review on your side. X is the exception: you bring your own X developer app, which takes about ten minutes and gives you your own rate limits.

Can an agent post and reply on my behalf?

Yes. Once you connect your accounts, the agent can publish posts, reply to comments, send direct messages, and respond to reviews through typed tools. It can run social_api_validate_post first to catch anything a platform would reject before the post goes out.

Is there a free plan for AI agents?

Yes. The free plan includes the MCP server and every platform, with no credit card. Paid plans remove the monthly post and interaction limits.
