MCP SERVER, AGENT SKILL, REST API
A chatbot writes captions from memory. ViralHunt gives Claude, Cursor, ChatGPT, n8n, OpenClaw or your own agent live tools: what is rising right now across 13 sources, your brand templates to make the picture, a draft queue a person reviews, and publishing to 11 networks once someone says yes.
The free key reads the radar: 24 queries a day at 60 requests an hour, no card. Publishing starts at Creator.
THE LOOP
The agent does the research and the writing. The decision to publish stays with a person, on every plan, by design and in code.
The agent reads what is rising right now across 13 sources: posts ranked by the engagement they gained since the last reading, the hashtags and sounds climbing with them, and the hour each network answers best. Live data, not what the model remembers.
It rewrites the angle in the brand's voice, fills one of your templates to make the picture, writes the short copy each network needs, notes its sources for the reviewer, and leaves the post in Drafts. Complete, dated, not sent.
A reviewer, a person or a second agent, grades the post against the content rule the platform serves: facts with a source, rights, network terms, tone. A fix sends it back with the note; an OK from the writer never counts.
An owner or admin approves. The post goes to 11 networks with its per-network copies, first comments and threads; every network answers with its link and every step is in the delivery log.

THREE JOBS AN AGENT RUNS
Take a page or an account, read its most viral posts across 13 sources, verify each story, rewrite it for the brand, make the picture on a template, leave a few complete drafts a day. In Claude Code it is one command, /viralhunt:job. A recipe does the same for a brand on a clock: source, template, networks, cadence, time.
A second agent reads the content rule the platform serves (what counts as a fact, a meme, a quote, a promo; which claims need a source; each network's limits) and grades every post waiting in Review with a verdict, scores and a note. One pass is /viralhunt:review. The grades per collaborator show up on the Team page.
Keywords per brand are searched on their own clock; the threads whose comments are growing right now arrive by webhook (Discord, Slack or your own endpoint, signed) and on the dashboard, with a daily digest. The agent proposes the reply as a board card; a person posts it. How the webhooks work.
WHAT THE AGENT CANNOT DO
COMPARE
The agent-first tools publish well. What they do not give the agent is the research (what is rising across 13 sources) and the review step before a bot posts. The rival cells are the cheapest listed plan that covers that many accounts, read on the date shown.

One brand is one account on each of the 11 networks. Most tools charge per account or per seat; ViralHunt charges per brand with all of them inside, so the same 11 accounts come to a fraction per account.
Rival prices read on 2026-10-10 (Post Bridge) and 2026-10-10 (Upload-Post) from their own pricing pages; the arithmetic is in each cell. "Not included" means the vendor does not list the feature. Third-party roundups disagree with each other, so they are not a source here.
FAQ
viralhunt-mcp on npm exposes the ViralHunt API as 51 typed tools over the Model Context Protocol, so Claude Desktop, Claude Code, Cursor, Windsurf or any MCP client can read rising posts across 13 sources, the top hashtags, trending sounds and the best time to post, fill your brand templates, leave complete posts in Drafts, review them against your content policy and, once a person approves, schedule them to 11 networks.
No. A member or an agent token can only leave a post in Drafts or send it to Review; only the organization owner, an admin, or a collaborator the owner marked as trusted can approve, and an OK a writer gives their own post never publishes it. A token can also be minted with fewer rights (reader, writer, reviewer) so the agent cannot reach the publish actions at all.
Claude on claude.ai through the skill; Claude Desktop, Claude Code, Cursor and any MCP client through viralhunt-mcp; ChatGPT through a Custom GPT with one Action; OpenClaw through its skill hub; n8n and Make through HTTP nodes; your own agent through the REST API with a personal token, or by webhook from the composer. Every one of them uses the same key.
The Free plan ($0, no card) includes a key: 24 content queries a day at 60 requests an hour, on posts 72 hours old and older, with the engagement numbers withheld. Creator ($29/mo, 1 brand, up to 11 connected accounts) lifts the daily cap, shows posts as they break with their numbers, and adds publishing at 100 requests an hour. Studio ($99/mo, 4 brands) has 2,000 requests an hour and Agency ($199/mo, 10 brands) 5,000.
Yes. A recipe is a standing order for a brand: what to post from (the radar, the quote base, the calendar of dates), on which template, to which networks, how often and at what time. The agent reads it through the API, runs it on its own clock, leaves the posts as drafts and stamps each run. The skill ships the loop as a command, so one line starts the daily job on a page or an account.
Yes. Connect it by webhook from the Agents page: ViralHunt signs a POST to your URL when someone asks it something from the composer, and your agent answers once. An agent with no public URL polls the same tasks through the API. OfficeMatrix, the open source office of agents, has the connection built in.
