ViralHunt

ViralHunt MCP Server

An MCP server for ViralHunt.io — the all-in-one platform to discover what's trending, curate it with your team, and publish everywhere. A BuzzSumo alternative with a built-in cross-network scheduler and an API that AI agents can drive end to end.

Get a free token: https://viralhunt.io/claude → create the free account (free forever, no card, 24 content queries a day), then Account → API Access → Create access. Every token has a permission group (reader, writer, reviewer, publisher, full): a tool outside the group answers 403 insufficient_scope naming what it lacks, and viralhunt_account shows the token its own group. Give an agent that writes a writer token and the one that reviews a reviewer token. Full API docs: https://viralhunt.io/api.

What an agent can do through this MCP server

These are the tools this server exposes (they drive the full discover → time it → publish → verify → correct loop). Every number comes with its sample size and time window, so an agent can say how much to trust it:

Tool	What it does
viralhunt_account	Who is this key — plan, daily quota left, credits, per-endpoint rules (call first)
viralhunt_trending	Find topics — what's going viral on TikTok, Instagram, X, Facebook, Pinterest, Bluesky, Douyin, Reddit, Mastodon, Tumblr, Hacker News and news RSS, ranked by viral score, each post with growth_24h (how much it moved between our two most distant readings); author narrows to one page or account
viralhunt_search	One keyword, every network — merged and ranked, with per-network totals
viralhunt_best_time	When to post — best weekday + hour per network from the posts that went viral there (365-day sample, hit rate, sample size, your time zone, optional niche keyword)
viralhunt_top_hashtags	Which hashtags — top tags per network or across all, by engagement, posts or per-post; one tag's breakdown by network
viralhunt_trending_sounds	Which sound — trending audio on TikTok, Instagram Reels and Douyin, cross-network sounds first, with the posts that used it
viralhunt_best_communities	Where to post — best subreddits (peak per 1,000 members, timing, top posts, similar) and Bluesky custom feeds for a topic
viralhunt_targets	List your brands/projects and the connected accounts you can post to, with needs_reconnect, per-network media_limits and the projects linked in another language
viralhunt_schedule	Publish now, schedule, or leave a draft (text + media, per-network copy, a first comment, or a design on a template the app renders when a person approves). The answer carries url, drafts_url, project_name: a post for a person goes to Drafts complete and is handed over in one five-line message (id and project, url, angle, verification, the decision needed), the rest in author_notes
viralhunt_drafts	The drafts waiting for a review and an approval, with their reviews
viralhunt_review_draft	Review a draft — verdict, score, per-network warnings, a note (an agent as the team's checker)
viralhunt_policy	The content rule a reviewer applies before any OK: block and fix lists with codes, six scores and thresholds, per-network notes (read it first, every pass)
viralhunt_review_queue	What needs a review: posts in Review with no verdict on their current content
viralhunt_calendar	The days worth a post: international days and science/tech/space/health anniversaries with why, by window and category
viralhunt_news_categories	The news categories with counts; pass one as category to viralhunt_trending (rss)
viralhunt_review_stats	Flags per collaborator by week, fortnight or month: reviews, ok / fix / block, rule codes, average risk10
viralhunt_approve_draft	Send a draft (owner/admin token, with the user's yes), optionally with its translations
viralhunt_translate_post	The same post in another language — the app adapts the copy and the template's texts for a linked project
viralhunt_edit_log	Learn from the edits — what people changed in drafts after the agent left them
viralhunt_get_post	Check a post's status + per-network results, permalinks and each network's own reason when it refused
viralhunt_sync_post	Refresh statuses from the networks
viralhunt_update_post	Edit a draft (anything, incl. the rendered png) or a still-scheduled post (body / media / networks / time)
viralhunt_cancel_post	Cancel the not-yet-published targets of a scheduled post, or drop a draft
viralhunt_stats	What performed — engagement of the published posts by network, by brand, top posts
viralhunt_quotes / viralhunt_mark_quote_used	The quotes base for daily-quote series (public domain by default, author context, portraits)
viralhunt_recipes / viralhunt_recipe_ran	Standing orders a person saved in the app: source, template, cadence; stamp a run
viralhunt_list_templates	Browse the content template library (on-brand layouts you fill; favourites first)
viralhunt_get_template	Get one template's full spec (html + css + variable manifest, what is static and what is dynamic, what it suits, the owner's instructions) to render
viralhunt_upsert_template	Author or edit a template — editing a curated one clones it into your copy (owner/admin)
viralhunt_assign_template	Assign a template to a project so its agents can use it (owner/admin)
viralhunt_board_context	The team's Editorial Board in one call: members (with ids), columns, categories
viralhunt_create_card	Hand a post to a teammate — create a kanban card (URL metadata auto-filled, assignee, priority, due date, category)
viralhunt_move_card	Move a card to another column (the is_done column completes it)
viralhunt_my_cards	The cards assigned to you (when the token belongs to an agent member of the team)
viralhunt_card_comments	Read or add comments on a card (notifies the assignee, mirrors to team chat)

Guardrails baked in: it won't post to the wrong brand, only schedules in the future, drafts by default unless the user asked to publish now, never uses another page's text or branded picture, checks each network's media ceilings, and is told not to repost fake news / copyrighted media / spam.

Changelog

• 1.1.29 (2026-10-24) — allow_duplicate on viralhunt_schedule and viralhunt_approve_draft: the duplicate firewall refuses an account another post of the last 72 hours already carries the same text for (duplicate_of; 409 duplicate_post when every account is one). A send whose every network was cut answers status: processing with checking: true: never create it again.
• 1.1.28 (2026-10-23) — all and limit on viralhunt_brand_hot (the most commented threads too, rising first: the app's dashboard list); the answer carries machine (the always-on Chrome's heartbeat), so an empty list is read against whether anybody is searching.
• 1.1.27 (2026-10-22) — carousel on viralhunt_create_post / viralhunt_update_post: several pictures are allowed only when the user asked for a carousel (else 422 multiple_pictures); png replaces the post's picture instead of being added next to it; a post made on a template always has ONE picture, its render.
• 1.1.26 (2026-10-20) — the brand's voice on every project of viralhunt_targets (the owner's playbook: read first, follow over the general rules, offer to draft one when empty); complete means every network's copy (X, Bluesky, Threads) in overrides in the same create, never a cut.
• 1.1.25 (2026-10-19) — every picture on one of the organization's templates (create the template when none fits; pass the PNG and the design, a PNG alone is a flat file nobody can edit); the working agreement in viralhunt_schedule: a post for a person goes to Drafts complete, never to Review unless asked, handed over in one five-line message with the url the answer gives; url, drafts_url, project_id, project_name on create, drafts rows and get.
• 1.1.24 (2026-10-19) — viralhunt_list_posts (the queue and the history per target), viralhunt_delete_post (take a published target down), account_id on viralhunt_cancel_post; retry on a timed-out create needs force.
• 1.1.23 (2026-10-18) — cards: assigned_to by id, name or email on viralhunt_create_card; viralhunt_assign_card, viralhunt_get_card, viralhunt_list_cards, viralhunt_archive_card. Drafts rows carry publishes[] (the text each account really sends).
• 1.1.22 (2026-10-15) — viralhunt_brand_keywords takes run: true ("search now"); viralhunt_brand_status carries machine (is the always-on machine alive).
• 1.1.21 (2026-10-15) — Brand watch: viralhunt_brand_status, viralhunt_brand_keywords, viralhunt_brand_hot (the discussions heating up right now, with links), viralhunt_brand_alerts, viralhunt_brand_webhook (signed deliveries to the brand's own agent).
• 1.1.20 (2026-10-15) — viralhunt_translate_post describes what comes back (shortened, overrides, no em dashes) and the one-brand-two-languages pattern.
• 1.1.19 (2026-10-14) — viralhunt_schedule takes stage and assigned_to; viralhunt_update_post takes assigned_to and answers the stage after the edit; viralhunt_drafts filters by assigned_to; viralhunt_get_post carries the full drafts shape (overrides, design, render…); viralhunt_get_template with preview shows a template before any post; a too-long text answers text_too_long instead of a 500.
• 1.1.18 (2026-10-14) — design is always sent for a template-made picture (and viralhunt_update_draft repairs a PNG-only post with it): the app can then edit the image.
• 1.1.17 (2026-10-14) — viralhunt_trending takes sort: most_commented on every network that counts comments (tiktok new; facebook and pinterest map it to most_comments, x, bluesky and mastodon to most_replied).
• 1.1.16 (2026-10-13) — viralhunt_upsert_template takes action: archive; update works whether the action comes in the body or the URL; viralhunt_list_templates takes scope, per_page, page and lists the organization's own templates first.
• 1.1.15 (2026-10-13) — every draft is an Editorial Board card (card_id on create) that moves with the post; design_fields on update fixes the texts inside a designed image (a trusted reviewer too); template authors without admin ("Creates templates" on Team); templates never carry code (removed in the answer).
• 1.1.11 (2026-10-08) — approve by a member token on its own graded post (when ticked on Team); review_stats carries avg_score, self_published, published_over_fix.
• 1.1.10 (2026-10-07) — the reviewer's edit boundary (overrides and kind only, when trusted); text_limit per account.
• 1.1.9 (2026-10-07) — kind on create and update (fact | meme | quote | opinion | promo): the reviewer applies only that kind's rules.
• 1.1.8 (2026-10-07) — overrides[account] takes first_comment and thread per account; Bluesky/Mastodon threads as a reply chain.
• 1.1.7 (2026-10-07) — author_notes on create and update: the source link for the reviewer, never published.
• 1.1.6 (2026-10-07) — the safety catch on a trusted reviewer's OK (risk_threshold), project_lang on drafts, review_stats for trusted reviewers.
• 1.1.5 (2026-10-07) — viralhunt_calendar: the calendar base (international days and anniversaries, with why), mark_used.
• 1.1.4 (2026-10-07) — viralhunt_news_categories and category on viralhunt_trending (rss); unknown parameters are a 422 on the API.
• 1.1.3 (2026-10-07) — the policy describes the kinds (fact, meme, quote, opinion, promo): a meme or a quote never gets a source or DOI demand.
• 1.1.2 (2026-10-06) — content_hash on viralhunt_review_draft (409 content_changed when the post moved under the reviewer); self review is by user, not token.
• 1.1.1 (2026-10-06) — the reviewer's four extra checks (picture against text, spelling, AI-written, facts with the DOI rule), risk10 1 to 10 on every review, viralhunt_review_stats (flags per collaborator).
• 1.1.0 (2026-10-05) — the reviewer job: viralhunt_policy, viralhunt_review_queue, needs_review on drafts; the server recalculates the verdict and names in sent.skipped the rule that kept an OK from sending.
• 0.3.0 (2026-09-28) — drafts and review (viralhunt_drafts, viralhunt_review_draft, viralhunt_approve_draft, viralhunt_edit_log), translation into a linked project's language (viralhunt_translate_post), design on a post and png on update, viralhunt_search, viralhunt_account, viralhunt_stats, viralhunt_quotes, viralhunt_recipes, viralhunt_sync_post; author and free-form time_range on trending; media_limits, needs_reconnect and language links on targets; templates say what is static, dynamic and what they suit; honest post statuses with each network's reason.
• 0.2.x (2026-09-08) — best time to post, top hashtags, trending sounds, best communities, the editorial board; Reddit, Mastodon, Tumblr and Hacker News on trending; growth_24h documented.
• 0.1.x (2026-08) — trending, targets, publish/schedule, get, update, cancel, content templates.

What ViralHunt the platform does (beyond this MCP)

ViralHunt is a full product; the tools above are the agent-drivable slice. The rest lives in the app (and some via the REST API):

• Trending Radar — a live cross-network feed of viral content by niche and time window.
• Cross-network publishing & scheduling — schedule/publish to up to 11 networks (Instagram, Facebook, TikTok, X, LinkedIn, YouTube, Pinterest, Threads, Bluesky, Telegram, Google Business), per brand.
• Editorial Board (team) — a kanban to curate before publishing: columns, categories, assignments, comments and team chat, so a team manages what goes out. (Cards/columns/comments are in the REST API.)
• Auto-DM (comment → DM automation) — when someone comments your keyword on Instagram, ViralHunt auto-replies and sends them a DM — like ManyChat, but flat pricing, unlimited contacts, and a monthly cap that resets. Configured in the app (runs via webhooks); Facebook next.
• Reports — what each brand/network actually did: posts, reach, DMs sent, replies, top content.

Note: Auto-DM and Reports are product features, not tools this MCP exposes today. The editorial board is exposed (context, cards, moves, comments) so an agent can hand content to a team instead of publishing it directly.
