The Best Social Media Tools for AI Agents in 2026 (MCP, API, Claude)
An agent needs two things to run a social account: a way to know what to post, and a way to post it. The tools in this group all solve the second: an API or an MCP server an agent calls from Claude, ChatGPT, Cursor, n8n or Make to publish and schedule. Where they differ is what happens before and after the call: whether the agent has anything to find content with, and whether a person gets to say yes before the post goes out.

Sí, y no caduca
Cada precio se leyó en la página del propio fabricante. No mostramos notas de G2 ni de Capterra porque no estamos listados ahí, y una nota inventada echaría abajo lo único que estas páginas tienen: que todo se puede comprobar.
Blotato
from $29/mo (7-day trial)
AI agent publishing (API + MCP)
Blotato calls itself "agent infrastructure for social media marketing": one API and one MCP server that publish to 9 platforms, with official n8n and Make nodes and MCP access from Claude Code, Cursor, Codex and ChatGPT. It is built for people who automate posting from an agent or a workflow. Plans: Starter $29, Creator $97, Agency $499 a month, each with a 7-day trial. It does not find content: the agent brings the post, Blotato publishes it.
Ventajas
Official n8n and Make nodes, MCP server for Claude Code, Cursor and ChatGPT
9 platforms through one API
Built for agents from the start
Limitaciones
Nothing to find content with: no trends, no radar, no corpus
No drafts, review or approval before an agent's post goes out
from $29/mo for 5 channels (7-day trial); self-hosting free
Open-source agentic scheduler
Postiz is an open-source "agentic social media scheduler": cloud plans from $29 a month (Standard, 5 channels) to $99 (Ultimate, 100 channels), or self-hosted on your own server at no licence cost. Every plan includes the hosted MCP server, the Postiz CLI, the public API and webhooks, so Claude, ChatGPT, Codex, Cursor or Gemini can schedule through it. It publishes to X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Threads, Pinterest, Reddit, Discord, Bluesky, Mastodon and more. Like Blotato, it is the last mile only: it does not find the content.
Ventajas
Open source and self-hostable
MCP server, CLI, API and webhooks on every plan
Wide network list including Reddit, Discord, Bluesky and Mastodon
Limitaciones
No trend or viral discovery
No drafts, review or approval gate for what an agent sends
ViralHunt is the one built for the whole loop: a Claude skill, an MCP server and a REST API through which the agent finds what is rising on 12 sources, drafts the post, fills a branded template, and leaves it in Review, where an owner, an admin or a trusted reviewer gives the OK that schedules it. Blotato and Postiz publish what the agent sends; ViralHunt also tells it what to send, and checks it against each network's rules before it can go out. Free plan with an API key, no card.
The dashboard, one section per network. This is the screen the tools above do not have, because none of them watches other people's posts.
Every price above was read off the vendor's own page and dated. ViralHunt has a free plan that does not expire, so you can check ours the same way.
La mayoría de las comparativas se escriben leyendo páginas de marketing. Esta no.
El precio de each of these tools se leyó en su propia página de precios, no en un resumen de terceros.
Cada función marcada como parcial dice "parcial". No convertimos un "casi" en un tick.
Donde each of these tools hace algo que nosotros no hacemos, la tabla lo dice.
Qué NO comprobamos, y por qué
No usamos each of these tools a diario durante semanas. Verificamos precios, condiciones de asientos y funciones documentadas; no publicamos una opinión sobre su interfaz que no nos hayamos ganado.
Los planes enterprise con presupuesto a medida quedan fuera: no hay cifra pública que verificar.
Y una que nos costó: durante meses esta tabla decía que Ahrefs empieza en $129/mes. Empieza en $29, y además tienen un plan gratuito. Inflábamos el precio de un competidor 4.4 veces, en la dirección que nos convenía. Lo encontramos al verificar y lo corregimos. Si ves otro error, es un error, no una táctica.
Frequently asked questions
How were these tools chosen?
They are the tools we are most often compared against in this category. Every figure comes from the vendor's own pricing page, read on the date shown on each comparison page, not from a third-party roundup.
Is this list ranked?
No. Ranking tools that answer different questions produces a number rather than an answer. Each entry says what it is the better buy for, and the section at the end says which to pick for which situation.
