Overview

AI-generated overview

Searches a crawled database of TikTok, Instagram and YouTube posts ranked by outlier score, and returns creator stats, transcripts and content ideas.

What you can do
  • Search posts and profiles by platform, keyword, handle, niche or score and view bands, and compare creators
  • Fetch a post or profile with stats, outlier scores, transcripts and visual breakdowns, and resolve public post URLs
  • Queue on-demand work: crawl a profile, request a transcript or visual analysis, download media, and poll job status
  • Research niches and trends, find related creators from a seed handle, hashtag or phrase, and remix a post into a new content idea
  • Manage monitoring: track or untrack profiles, watchlists, viral email alerts and a feed of newly discovered posts
  • Check credit balance and pricing, create a Stripe top-up link, and report issues
When to use it
Useful for social media content research: spotting overperforming posts in a niche, vetting or comparing creators, and turning proven formats into new content ideas. Also fits ongoing monitoring of chosen accounts through scheduled crawls and email alerts.
Requirements
Remote streamable HTTP endpoint; no local install. An API key is sent in the x-api-key header, created in the provider's settings. The trending tool and pricing are free and unauthenticated; most other tools spend credits.
Before you install
Most tools consume paid credits, and some (transcripts, visual analysis, crawls, scheduled refreshes) charge on queueing or per refresh; auto top-up can be configured. create_topup_link produces a Stripe payment link. Tools create, change and delete watchlists, tracking and email alerts, and send alert emails to an address you supply. Crawled public profile and post data goes to the provider.

Installation

In SourceWeft

  1. Open Viral Outliers in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.viraloutliers%2Fviral-outliers/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

search_outliers

Search Viral Outlier Posts

Search a continuously-crawled database of social media posts ranked by outlier score: how strongly a post overperforms the account's own baseline. Filter by platform, keyword, exact creator handle, content type, an outlier-score band (min/max), a view band (min/max), a follower band (min/max), an engagement-rate band (min/max) and time window; sort by outlier score, views, likes, engagement or recency. Returns post metadata, stats and thumbnails. Use this to find proven viral formats in any niche before creating content. Results may include deleted posts (deleted_at set) and posts from deactivated profiles (profile is_active=false), these are kept for their thumbnails and format ideas, with stats frozen at deletion; filter on deleted_at / is_active if you only want live content. Cost: 1 credit per 25 posts returned.

search_profiles

Search Social Media Profiles

Search tracked social media profiles by handle or name, filtered by platform. Returns profile metadata, follower counts and average performance stats. Use it to resolve a handle to a profile id before fetching stats or posts, or to discover creators in the database. Results may include deactivated profiles (is_active=false), e.g. an account that was renamed or went private, retained with frozen stats; filter on is_active if you only want live accounts. Note a creator who changed handles can appear as two rows (old deactivated + new active). Cost: 1 credit per 25 profiles returned.

ParameterspagequerypageSizeplatformscategoryId

list_categories

List Niche Categories

Returns the curated niche taxonomy (up to four levels, e.g. "Health > Exercise > Gym") with, for each category, its id, path, level, parent and how many active profiles are categorized under it including its sub-niches. Only categories with at least minProfiles profiles in their subtree are returned (default 5), so every id you get back yields a real result set. Pass a categoryId to search_outliers, search_profiles or niche_trends to scope them to the creators in that niche; the filter always covers the subtree. Free to call and cached, so call it at the start of a session and reuse the ids. Categories are assigned per creator by our categorizer (reviewed by hand for new niches), which makes this filter more precise than a keyword over captions: it catches creators whose captions are hashtag-only or not in English. Cost: free.

ParametersmaxLevelminProfiles

get_post

Get Post Details

Fetch a single post by id: views, likes, comments, engagement rate, outlier scores for seven time windows, thumbnail and the owning profile. When a transcript or visual analysis already exists it is included at no extra cost. The visual analysis is a structured scene-by-scene breakdown (per-scene timing, on-screen text, visual elements and a recreation note) plus an overall-style summary. Request new enrichment via request_transcript (speech / on-screen text) or request_visual_analysis (scene breakdown). Use after search_outliers to deep-dive a result. Cost: 1 credit per call.

ParameterspostIdrequiredincludeTranscriptincludeVisualAnalysis

get_profile

Get Profile Stats

Fetch one tracked profile by id: follower count, bio, average views/likes/engagement across time windows, and recent tracked posts. The averages are the baseline outlier scores are computed against. Use search_profiles first to resolve a handle to an id. Cost: 1 credit per call.

ParametershandleplatformprofileId

request_transcript

Transcribe a Post

Queues AI transcription of the spoken audio for a video post. Accepts a public post URL or an internal post id. Asynchronous: returns a job reference to poll with get_job_status; once complete the transcript is attached to get_post responses. Credits are charged on queueing and automatically refunded if the job fails. Image slideshows and photo posts have no audio and are rejected up front with no charge: use request_visual_analysis for their on-screen text instead. Cost: 10 credits per call.

ParametersurlpostId

request_visual_analysis

Analyze a Post Visually

Queues a structured visual analysis for a post: for a video, a scene-by-scene breakdown (per-scene timing, scene type, on-screen text, visual elements and a recreation note) plus an overall-style summary (color palette, text style, editing pace); for an image slideshow, per-slide text and visual descriptions. Accepts a public post URL or an internal post id. Asynchronous: returns a job reference to poll with get_job_status; once complete the analysis is attached to get_post responses (includeVisualAnalysis). Credits are charged on queueing and automatically refunded if the job fails. This is the visual twin of request_transcript. Cost: 10 credits per call.

ParametersurlpostId

crawl_profile

Crawl a New Profile

Submits a public profile for crawling: profile metadata plus its recent posts, stats and thumbnails, after which it stays tracked and appears in searches. Asynchronous. Returns a job reference for get_job_status. If the profile is already tracked, this returns immediately without charging a full crawl. Credits are refunded automatically when a crawl fails. Cost: 40 credits per call.

Parametershandlerequiredplatformrequired

get_job_status

Check Job Status

Returns the status of an asynchronous job started by crawl_profile or request_transcript: pending, processing, completed or failed. Free to call: polling must never cost credits. Poll every 10–30 seconds; jobs typically complete within a few minutes. Cost: free.

ParametersjobRefrequired

get_credit_balance

Check Credit Balance

Returns the current API credit balance for the authenticated account, plus the automatic top-up state of the account (autoTopup: configured, enabled, pack, monthly charge cap and count, last error) so an agent can tell whether a zero balance is a hard stop or refills itself on the next billable call. Free to call. Agents should check the balance before starting large batch jobs and surface "insufficient_credits" errors to the user with a link to top up. Cost: free.

Takes no parameters.

compare_profiles

Compare Profiles Head-to-Head

Compares 2–5 tracked profiles (by profile id or platform+handle) and returns each one's stats (follower count, average views/likes across time windows, engagement rate) plus a computed ranking flagging the top performer by followers and by engagement. Pure lookup, fast. Unresolved profiles come back in a notFound list rather than failing the call. Cost: 2 credits per call.

ParametershandlesprofileIds

resolve_post_url

Resolve a Post URL

Takes a public post URL (TikTok video/photo, Instagram post/reel, YouTube video/short) and resolves it to the tracked post: the entry point when your input is a link. found:true returns the postId for get_post, request_transcript, download_post_media and remix_post. found:false tells you whether the whole profile is untracked (call crawl_profile) or just this post. Note that remix_post accepts an untracked URL directly and ingests it itself, so for a remix you can skip this lookup. TikTok/Instagram short links (vm.tiktok.com, /share/) must be expanded to the canonical URL first. Cost: 1 credit per call.

Parametersurlrequired

download_post_media

Download Post Media

Returns direct media URLs for a tracked post, the video file, or slideshow images with positions. Accepts a public post URL or an internal post id. When media is not stored yet it queues an on-demand fetch and returns a jobRef to poll (typically ready within ~90 seconds); call again once complete. Platform CDN URLs can expire, so download promptly. YouTube currently returns the thumbnail image. You are responsible for using downloaded media in line with the platforms' terms and applicable law. Cost: 3 credits per call.

ParametersurlpostId

remix_post

Remix a Post to Your Niche

Takes a post (pass a public post URL or an internal post id) plus a target niche/brand description, and produces an adapted content idea: rewritten title and description, segment-by-segment script, a short analysis of why the original went viral, and an execution checklist, the proven format transplanted into your niche. The URL does NOT need to be tracked: an unknown post is fetched and ingested automatically as part of the job, so any public TikTok/Instagram/YouTube link works with no crawl_profile round-trip. Asynchronous (~1–3 minutes, a few minutes longer for an untracked URL): returns a jobRef; poll get_remix_result until its "remix" field is populated (it returns status + result together). For video posts the remix auto-generates the transcript and visual analysis first, so quality no longer depends on you transcribing beforehand. Credits are refunded automatically if the remix fails. Cost: 20 credits per call.

ParametersurltonepostIdtargetNicherequired

get_remix_result

Fetch a Finished Remix

Returns the finished remix for a remix_post job: adapted title, description, script segments, why-it-went-viral analysis (whyItWorks) and checklist. Free to call. Poll get_job_status until the job reports completed, then fetch here. The result is also viewable in the web app under Content Ideas. Cost: free.

ParametersjobRefrequired

report_issue

Report an Issue

Report a problem with any skill: an error you keep hitting, data that looks wrong or stale, or something you needed that the API could not do. Free: never spend credits on telling us something is broken. Include what you called, what you expected and what happened. Set wantsUpdate to true to get an email on your account address when the issue is resolved. Reports go straight to the team. Cost: free.

ParametersskillmessagerequiredwantsUpdate

track_profile

Monitor a Profile

Starts monitoring a profile so it is automatically re-crawled at a cadence you choose (daily, every_3_days or weekly), keeping its posts and stats fresh without you polling crawl_profile. Identify the profile by profileId, platform+handle, or a public profile/post URL. Managing monitoring is free; each scheduled refresh crawl costs credits (10 per refresh) and monitoring pauses itself if your balance runs out, then resumes when you top up. The profile must already be in the database; crawl_profile it first if it is not. Calling again on an already-monitored profile just updates the cadence. Pull the new posts with get_tracked_updates. Cost: free.

ParametersurlhandleplatformfrequencyprofileId

untrack_profile

Stop Monitoring a Profile

Stops monitoring a profile: no further scheduled refresh crawls are charged for it. Free to call. Pass the internal profileId (from list_tracked_profiles or search results). The profile and its already-crawled posts stay in the database and searchable; only the recurring refresh stops. Returns not_found if the profile is not currently being monitored. Cost: free.

ParametersprofileIdrequired

list_tracked_profiles

List Monitored Profiles

Returns every profile you are currently monitoring, with its handle, platform, follower count, refresh cadence, next scheduled crawl time, when it was last checked for updates, and any paused reason (e.g. paused for insufficient credits). Free to call. Use it to audit what is being refreshed and what it is costing, or to grab a profileId for untrack_profile. Cost: free.

Takes no parameters.

create_viral_alert

Email Me When a Profile Goes Viral

Creates a viral alert: we watch a TikTok, Instagram or YouTube profile and email the address you give when it publishes a post whose outlier score (views divided by the profile's own average) reaches minOutlierScore (default 3, minimum 1.5) within postAgeDays of posting (default 7, max 30). Identify the profile by profileId, platform+handle, or a public URL; it must already be in the database (crawl_profile it first if not). Setting up, listing and deleting alerts is free. Two things cost credits: the refresh crawl that keeps the profile fresh (10 credits per run, daily by default, started for you if you are not already monitoring the profile with track_profile) and each alert email actually sent (5 credits). Limits: one alert email per destination address per day, sent around sendHour in your timezone (defaults 9, UTC) and bundling every alert that fired; 3 emails per alert in total, after which the alert ends; expiresInDays (default 30, max 90) ends it regardless; 25 active alerts per account. A post can trigger an alert only once. Your account email needs no confirmation; any other address receives a confirmation link first and nothing is sent until it is clicked. Every alert email has its own stop link. Calling again for the same profile and address updates the settings instead of creating a duplicate. Cost: free.

ParametersurlemailrequiredhandleplatformsendHourtimezonefrequencyprofileIdpostAgeDaysscoreWindowexpiresInDaysminOutlierScore

list_viral_alerts

List Viral Alerts

Returns your viral alerts (active first, then recently ended, up to 100) with the watched profile, destination email and whether it is confirmed, threshold and score window, post age window, preferred send hour and timezone, emails sent out of the cap, paused or ended reason, expiry and the last email time. Free to call. Use it to audit what is being watched, to check whether a third-party address has confirmed, or to grab an alertId for delete_viral_alert. Cost: free.

Takes no parameters.

delete_viral_alert

Delete a Viral Alert

Ends a viral alert by alertId (from list_viral_alerts or create_viral_alert). Free. If this alert is what started the profile's tracking and no other active alert of yours needs it, the paid refresh crawls stop as well; tracking you started yourself with track_profile is left untouched. Returns not_found when the alert does not exist or already ended. Cost: free.

ParametersalertIdrequired

create_watchlist

Create a Watchlist

Creates an empty watchlist (a named set of creators) and returns its watchlistId. Fill it with add_watchlist_profiles, then pass the id to search_outliers as watchlistId to scope any search to exactly those accounts. Watchlists created here appear in the owner's web app too. Free to call. Watchlists count against a workspace allowance that comes from a subscription or is earned from API spend (every API key holder starts with 1); an over-limit call explains what unlocks more. Cost: free.

Parametersnamerequirednotes

list_watchlists

List Your Watchlists

Returns every watchlist on the account (both agent-created and web-app-created) with its watchlistId, name, notes, profile count and last-updated time. Free to call. Use it to recall an id for search_outliers, add_watchlist_profiles or get_watchlist. Cost: free.

Takes no parameters.

get_watchlist

Get a Watchlist

Returns a single watchlist by watchlistId with every member profile: profileId, handle, platform and follower count. Free to call. Use it to review or explain a list before searching it, or to pick profileIds for remove_watchlist_profiles. Cost: free.

ParameterswatchlistIdrequired

add_watchlist_profiles

Add Creators to a Watchlist

Adds creators to one of your watchlists. Pass profileIds (from search_profiles or any search result) and/or handles as {platform, handle} pairs; up to 25 per call. Creators must already be tracked (crawl_profile first if not; unresolved ones come back in notFound). Already-present creators are reported, not duplicated. Free to call. Each added creator counts against your followed-profiles allowance, which comes from a subscription or is earned from API spend; an over-limit call explains what unlocks more. Cost: free.

ParametershandlesprofileIdswatchlistIdrequired

remove_watchlist_profiles

Remove Creators from a Watchlist

Removes the given profileIds from a watchlist and returns how many were removed plus the new profile count. Free to call. Use get_watchlist to find the profileIds. Cost: free.

ParametersprofileIdsrequiredwatchlistIdrequired

delete_watchlist

Delete a Watchlist

Deletes one of your watchlists including its memberships, and frees the watchlist slot and followed-profile slots it used. Free to call. Works for lists created through the API or in the web app; only the owner can delete a list. Cost: free.

ParameterswatchlistIdrequired

get_tracked_updates

Get New Posts From Monitored Profiles

Returns the posts newly discovered (first stored by our crawler) since your last check, across all the profiles you are monitoring. Free to call. Each call advances a per-profile cursor, so a subsequent call only returns posts crawled after it (a feed, not a re-scan). New posts arrive when a profile's scheduled refresh crawl runs, on the cadence set by track_profile. Results are the same flattened post shape as search_outliers (stats, thumbnail, handle). Total posts are capped (limit 1–100, default 50). Cost: free.

Parameterslimit

get_pricing

Get API Pricing

Returns the current price list as structured JSON: the USD value of one credit, every skill with its credit cost and REST route, the one-time credit packs, and every subscription plan with its monthly and yearly price, included API credits per month, and watchlist limits. Free and unauthenticated, so an integrator can render live costs to their own users, or an agent can compare subscribing against buying packs, without hardcoding prices or holding an API key. Billable calls also return X-Credits-Charged and X-Credits-Balance response headers, so a reseller can attribute spend per call. Cost: free.

Takes no parameters.
