reach-mcp

A controllable multi-source search MCP server for AI agents. Search Reddit, X, YouTube, Hacker News, GitHub, arXiv, Polymarket, 微博, 知乎, 豆瓣, 头条, 雪球, V2EX, B站, 小宇宙 and more -- you pick the sources, the window, and whether to synthesize. 33 sources across Chinese & English platforms, with adjustable time window, source/category scoping, trending hot lists (微博/知乎/头条热搜...), and optional LLM synthesis.

Why

last30days (mvanhorn/last30days-skill) wraps the search in a fixed pipeline: the agent passes a query and gets back a finished brief. It can't choose which sources to hit, can't widen or narrow the time window (hardcoded to 30 days), can't see the raw scored rows, and can't reuse them. Every call re-searches everything.

reach-mcp keeps the same core machinery -- parallel multi-source fetch, engagement-based scoring, cross-source dedup/clustering, an optional LLM-synthesized cited brief -- and exposes it as a plain MCP server whose knobs the agent controls per call:

• 🔌 Pick your sources. sources=["reddit","arxiv","xueqiu"] or omit for all configured ones.

• 📅 Pick your window. days=7 for this week, days=180 for the half-year -- no longer fixed at 30.

• 🪓 Decide what matters. synthesize=false returns raw scored rows for the agent to reason over itself; synthesize=true (default) also runs an LLM rerank + brief. max_chars_per_item sets each row's text-snippet length (default 500) -- raise it for fuller CN posts, lower it to save tokens.

• 🌐 Chinese & English sources in one call -- 微博, 知乎, 豆瓣, 头条, 雪球, V2EX, B站, 小宇宙, 小红书 alongside Reddit, X, YouTube, HN, GitHub, arXiv and the rest.

• 🛡️ Polite by default -- per-host pacing, honors Retry-After, bounded timeouts. Never hammers a site.

Sources (33)

💰 Apify gives $5 free credits EVERY MONTH (recurring, not one-time) on the Free plan -- enough for hundreds of search runs. Set APIFY_API_TOKEN to enable quora + boost tiktok/threads/instagram/pinterest/linkedin. tiktok and threads have FREE playwright backends (in-page fetch / SSR scrape) that need no credential at all when playwright+chromium is installed.

⚠️ ScrapeCreators is 100 credits one-time, not free recurring. It's now the lowest-priority fallback for tiktok/instagram/pinterest -- prefer Apify (monthly free) or OpenCLI (desktop, free). LinkedIn uses Apify for public posts (same APIFY_API_TOKEN, no LinkedIn login).

Query syntax by source

Each source has its own search-query rules. Multi-word/long queries may return fewer results on some backends — the agent should tune the query per source.

General guidance: prefer short, specific keywords (2-4 words). Very long queries or phrases that only a specific site would phrase identically will often return [] — the backend isn't broken, the query is too specific.

MCP tools

search -- the primary tool

Description:

Search up to 33 social & web sources in parallel, score by engagement, optionally synthesize a cited brief. YOU control scope.

Best scoping: category -- social: x, reddit, instagram, threads, tiktok, xiaohongshu, bilibili, youtube, pinterest, bluesky, linkedin, web, weibo, zhihu, douban, toutiao; it: github, hackernews, v2ex, rss, arxiv, dripstack, stackoverflow, lobsters; tech: arxiv, techmeme, digg, dripstack, hackernews; polec (politics & economics): truthsocial, xueqiu, stocktwits, polymarket; podcast: xiaoyuzhou. Categories overlap (e.g. arxiv is both it and tech) -- multiple categories union. sources picks individual names; both together = union; both omitted = all available sources EXCEPT podcast (xiaoyuzhou is opt-in: episode transcription is slow, request it explicitly when you need podcasts). Search returns metadata + a snippet per item -- xiaoyuzhou/youtube/bilibili are NOT transcribed/captioned here. With synthesize=true the top rich-media items are auto-backfilled with full content before the brief; with synthesize=false call fetch_content on any item you want in full. max_chars_per_item caps snippet length (raise for fuller CN posts, lower to save tokens).

Returns {brief, items, sources_used, source_summary, available_sources}. Each item: {source, title, url, author, date, score, engagement, text}. source_summary is one compact line per outcome -- 'x:3; reddit:5 | EMPTY: rss, v2ex | QUOTA: tiktok(monthly limit) | ERRORS: digg(429) | NOTICE: zhihu(ZHIHU_COOKIE search failed — showing 热榜 instead; refresh the cookie)'; 'gated_off' means its credential env isn't set; NOTICE marks a degraded-but-working source (stale cookie fell back to a limited path) — usable data, but surface the caveat. Match query language to platform -- Chinese keywords work best for the CN sources. WeChat 公众号 queries on web auto-scope to mp.weixin.qq.com. Call list_sources if unsure what's configured.

list_sources

Inventory of all registered sources. Call before search when unsure what's active. Returns [{name, description, needs_auth, available, required_env, default_days, default_limit}]: available=false = gated (credential in required_env not set). No arguments.

synthesize

LLM-synthesize a cited brief from items returned by a prior search(synthesize=false), WITHOUT re-searching. Args: query (the original), items (the prior items list). Returns {brief}.

fetch_content

Fetch the full content of ONE item found via search. Two-stage retrieval: search returns metadata + a snippet for every source; call this when an item is worth reading/hearing in full. Rich-media sources have dedicated backends -- xiaoyuzhou (pass the item's audio_url → Whisper transcript), youtube (watch URL or video id → captions), bilibili (video URL → CC subtitles if any); every other source falls back to Jina Reader on the item's url. Args: source, id_or_url. Returns {source, url, content, ok}.

read_url

Fetch any URL as clean markdown via Jina Reader. Use for the full text of a page found via search -- a thread, article, or repo -- when the item's text snippet isn't enough. Returns {url, content, ok}; content is '' on failure. Keyless.

For agents -- quick usage guide

1. list_sources()                         # see what's configured; pick targets
2. search("Peter Steinberger",
          sources=["reddit","x","github","youtube"],
          days=14, synthesize=false)      # get raw scored rows, reason yourself
   -- or --
   search("OpenAI vs Anthropic",
          category=["tech","it"],
          days=30, synthesize=true)          # scope by topic group
   -- or --
   search("OpenAI vs Anthropic",
          days=30, synthesize=true)          # one call → cited brief + rows
   -- or --
   search("", trending=true,
          sources=["weibo"])              # hot lists, not keyword search
3. (optional) synthesize(query, items)     # re-brief the rows you already have

• Default (sources=None, category=None, synthesize=true): searches every configured source EXCEPT podcast (opt-in), auto-backfills full content for the top rich-media items, and returns a cited brief + all rows. Simplest.

• By type (category=["tech"]): one keyword scopes to a topic group (social / it / tech / polec / podcast) -- the easiest way to match the sources to the kind of query. Categories overlap; several union together.

• Targeted (sources=[...]): only hit what you need -- faster, cheaper, less noise. Combines with category (union).

• Trending (trending=true): query-free hot lists -- weibo 实时热搜 (heat values, no login), zhihu 热榜, hackernews front page, lobste.rs hottest, bilibili 综合热门, x/X trends (trends24 mirror, no login), github newly-hot repos (created this week, sorted by stars). query is ignored; sources scopes. Use for "what's hot on weibo right now" / "今日热搜". Non-trending sources you name come back as skipped.

• Raw (synthesize=false): metadata + snippets only, no backfill -- fast. Read the rows, then fetch_content(source, id_or_url) on the ones worth full text, and synthesize(query, items) to re-brief.

• Podcast (category=["podcast"] or sources=["xiaoyuzhou"]): opt-in because transcription is slow (minutes per episode) -- enable only when you actually need podcasts.

• Rich-media sources (xiaoyuzhou/youtube/bilibili) are metadata-only at search time; their transcripts/captions come from fetch_content (or the synthesize=true auto-backfill).

• A gated source you name returns gated_off in sources_used -- set its credential env and retry, or drop it.

• One broken source never breaks a search; check sources_used for what failed.

Install

Option A -- uvx in your MCP host (recommended for OpenWebUI / mcpo)

// mcpo config.json
"reach": {
  "command": "uvx",
  "args": ["reach-mcp", "--transport", "stdio"]
}

Or streamable-HTTP: uvx reach-mcp --transport http --host 0.0.0.0 --port 8765.

Option B -- Docker

docker pull ghcr.io/xyonium/reach-mcp:latest
docker run -p 8765:8765 --env-file .env ghcr.io/xyonium/reach-mcp:latest

See docker-compose.yml for a full example with all available env vars (including optional xiaohongshu-mcp companion service).

Option C -- mcpo (multi-server host, recommended for OpenWebUI)

mcpo launches many MCP servers via uvx and exposes each as an OpenAPI endpoint. If you're already running the last30days server through mcpo, reach-mcp drops into the same slot -- just swap the config.json entry.

1. config.json -- list reach-mcp (see deploy/mcpo-config.example.json for the full env set):

{
  "reach": {
    "command": "uvx",
    "args": ["reach-mcp", "--transport", "stdio"],
    "env": { "SEARXNG_URL": "http://searxng:8080", "OPENAI_API_KEY": "sk-..." }
  }
}

2. entrypoint.sh -- deploy/entrypoint.sh installs reach-mcp's runtime deps on first start (cached under the mounted volume): yt-dlp (youtube), bili-cli (bilibili - handles B站 wbi/412), gh (github), Go + digg/arxiv/techmeme pp-cli. Copy it into your mcpo config dir.

⚠️ mcp SDK 2.x pin: mcpo 0.0.20 (and several uvx-launched MCP servers) import 1.x mcp SDK symbols that mcp 2.0 renamed, and crash with ImportError: cannot import name 'streamablehttp_client'... / McpError. The entrypoint sets UV_CONSTRAINT=/config/uv-constraints.txt (mcp<2), which mcpo inherits into every child uvx process. Ship deploy/uv-constraints.txt next to your entrypoint.sh to customize; if absent, the entrypoint writes the same default.

3. compose -- deploy/docker-compose.mcpo.yml mirrors a production setup with UV_CACHE_DIR/UV_TOOL_DIR/npm_config_cache persistence, plus optional Searxng and xiaohongshu-mcp companion services:

mcp:
  image: ghcr.io/open-webui/mcpo:latest
  volumes:
    - ./mcpo-config:/config        # entrypoint.sh + config.json
  environment:
    UV_CACHE_DIR: /config/uv-cache
    UV_TOOL_DIR: /config/uv-tools
    UV_TOOL_BIN_DIR: /config/uv-bin
    PATH: /config/uv-bin:/config/bin:/config/go/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
    npm_config_cache: /config/npm-cache
  entrypoint: ["/bin/bash", "/config/entrypoint.sh"]
  command: ["--host", "0.0.0.0", "--port", "8000", "--config", "/config/config.json"]

OpenWebUI then connects to http://mcp:8000/reach (OpenAPI) or http://mcp:8000/reach/mcp (native MCP).

OpenWebUI tool description (copy-paste): OpenWebUI lets you override a tool's human-facing description. The one below matches reach-mcp's actual categories and defaults — paste it into the tool's description field so users see what the server can do:

一次查询横跨 33 中英文信息源 —— 社媒通用（全网搜索、小红书、微博、知乎、豆瓣、头条、linux.do、B站、X/Twitter、Reddit、Instagram、Threads、TikTok、YouTube、Pinterest、Bluesky、LinkedIn、quora）、IT 技术（GitHub、Hacker News、V2EX、RSS、arXiv、Dripstack、Stack Overflow、Lobste.rs）、科技（arXiv、Techmeme、Digg、Dripstack、Hacker News）、政经（雪球、Truth Social、Stocktwits、Polymarket）、播客（小宇宙——转录较慢，按需启用）。热搜热榜模式：微博实时热搜、知乎热榜、头条热榜、linux.do 每日热门、B站热门、X trends、GitHub 周热榜、HN front page、Lobste.rs 热门。

Upgrading deps: touch /config/UPGRADE in the config dir, then restart the container -- the entrypoint clears its binary caches and reinstalls fresh (yt-dlp, bili-cli, pp-cli, etc.).

OpenCLI note: the OpenCLI desktop boost (tiktok/instagram/pinterest/xueqiu) is intentionally NOT installed in this headless container -- those sources use their server-side backends (Apify / public APIs / Searxng), which is the intended default. OpenCLI only applies if you run mcpo on a desktop machine with Chrome.

Configuration

All config is environment variables (a Settings dataclass). Everything is optional -- the server degrades to free-source-only mode if you set nothing.

Credential guide

按顺序获取每个 key 的完整步骤、入口 URL、以及推荐 RSS feed 清单,见 docs/CREDENTIALS.md。本节省略版;下面列出每个 key 的用途和快速要点。

X / Twitter (AUTH_TOKEN, CT0)

1. Log into x.com in any browser

2. Open DevTools (F12) → Application → Cookies → x.com

3. Copy the values of auth_token and ct0

4. Set AUTH_TOKEN=<auth_token value> and CT0=<ct0 value>

⚠️ Use a dedicated account; API-like usage may trigger platform anti-bot detection.

Bluesky (BSKY_HANDLE, BSKY_APP_PASSWORD)

1. Log into bsky.app → Settings → App Passwords

2. Create a new app password; copy the generated value

3. Set BSKY_HANDLE=yourhandle.bsky.social and BSKY_APP_PASSWORD=<generated password>

GitHub (GH_TOKEN)

1. GitHub → Settings → Developer settings → Personal access tokens → Fine-grained tokens

2. Create a token with Public Repositories (read-only) access

3. Set GH_TOKEN=github_pat_...

Without GH_TOKEN, GitHub search still works but hits unauthenticated rate limits (60 req/hr vs 5000 req/hr).

Truth Social (TRUTHSOCIAL_TOKEN)

1. Log into truthsocial.com in a browser

2. Open DevTools → Network tab → find any API request to truthsocial.com

3. Copy the Authorization: Bearer ... header value

4. Set TRUTHSOCIAL_TOKEN=<the bearer token>

ScrapeCreators (SCRAPECREATORS_API_KEY)

⚠️ 100 credits one-time, then paid from $10/mo. Signup gives 100 free credits (no credit card, no monthly reset). A single comprehensive search can consume 50--150+ credits. Only enable SC-backed sources (tiktok, instagram, pinterest) if you're OK with the cost.

1. Sign up at scrapecreators.com (free, no credit card)

2. Copy your API key from the dashboard

3. Set SCRAPECREATORS_API_KEY=sc_...

One key enables three SC-only sources (and an optional LinkedIn boost):

• tiktok -- TikTok search (no free alternative exists)

• instagram -- Instagram search (Meta API requires app review)

• pinterest -- Pinterest search (no free alternative exists)

• linkedin -- Optional boost (Apify is the primary)

LinkedIn

LinkedIn searches public posts via Apify (apimaestro/linkedin-posts-search-scraper-no-cookies) -- keyword search, no LinkedIn cookies/login needed:

1. Set APIFY_API_TOKEN (same key as tiktok/instagram/pinterest; $5 free credits/month recurring)

2. That's it -- linkedin is enabled alongside the other Apify sources

Without an Apify token it falls back to a site:linkedin.com query through your configured Searxng (free but sporadic -- LinkedIn blocks most crawlers). Jina's s.jina.ai was removed 2026-08: it doesn't index LinkedIn (every query returned 0) and burns one-time tokens. r.jina.ai stays for read_url (page reader, no search tokens).

Optionally, setting SCRAPECREATORS_API_KEY adds ScrapeCreators results in parallel for a richer result set.

DripStack (financial newsletters)

Free and keyless -- always available, no setup. Search over premium financial newsletters (Substack/analyst write-ups). Best for ticker/company research. Complements stocktwits (retail sentiment) and polymarket (real-money odds).

RSS feeds (RSS_FEEDS)

Generic RSS/Atom source, free (uses feedparser, already a dependency). Set RSS_FEEDS to a comma-separated list of feed URLs; entries are filtered to the query within the recency window.

RSS_FEEDS="https://hnrss.org/frontpage,https://www.federalreserve.gov/feeds/press_all.xml"

Xiaohongshu / 小红书 (XHS_MCP_URL)

Uses the community-vetted xiaohongshu-mcp Go server (15K+ stars) as backend.

Docker (recommended): Add to your compose file (see docker-compose.yml). The ./data volume is required — it stores the login cookies (they are lost on recreate without it); ./images is only needed if you publish notes:

xiaohongshu-mcp:
  image: ghcr.io/xpzouying/xiaohongshu-mcp:latest
  ports: ["18060:18060"]
  restart: unless-stopped
  init: true
  tty: true
  volumes:
    - ./data:/app/data
    - ./images:/app/images
  environment:
    - COOKIES_PATH=/app/data/cookies.json
    - HOME=/app/data/home
    - XDG_CONFIG_HOME=/app/data/config

Then set XHS_MCP_URL=http://xiaohongshu-mcp:18060/mcp and log in (below).

Login (QR scan, once): the image runs only the MCP server — there is no separate login binary. Start it, then scan the QR via any MCP client:

npx @modelcontextprotocol/inspector      # MCP Inspector
# connect to http://localhost:18060/mcp
# call `get_login_qrcode` → QR code appears → scan with the 小红书 App
#    (older images called it `login`; v2.0.0 renamed it)
# call `check_login_status` to confirm (older images: `check_login`)

⚠️ Accounts registered with a non-mainland (境外) phone get routed to rednote (the international Xiaohongshu), and scanning with the mainland app keeps showing "not logged in". Use the mainland 小红书 app + a mainland-registered account. Notes: open the App before scanning (the QR expires quickly); don't log the same account in elsewhere on the web — 小红书 single-logs-in, a web login kicks the MCP account out. Cookies persist in the ./data volume.

Without Docker: Download the binary from releases. Login is the same QR flow via the MCP login tool (or go run cmd/login/main.go from source), then start the server and set XHS_MCP_URL=http://localhost:18060/mcp.

Weibo / 微博 (no credentials)

Free, zero-config. Two-step pure-HTTP flow against the mobile realm (curl-verified 2026-08): visitor.passport.weibo.cn/visitor/genvisitor2 mints SUB/SUBP visitor cookies in one call, then m.weibo.cn/api/container/getIndex returns real search results (text/author/interactions). Cookies are cached module-level and auto-regenerated on auth failure (ok:-100). The desktop site (s.weibo.com) needs JS fingerprinting and is NOT used.

Zhihu / 知乎 (ZHIHU_COOKIE optional)

Two tiers, both curl-verified 2026-08:

• With ZHIHU_COOKIE — real search via search_v3. Paste the browser Cookie: request header from a logged-in zhihu.com session (must contain z_c0 and d_c0; F12 → Network → click any request → copy the Cookie header value). Works WITHOUT the x-zse-96 signature as long as the cookie rides along. Returns answers/articles with upvote/comment counts.

• Without it — 热榜 hot-list browse via the unauthenticated mobile API (api.zhihu.com/topstory/hot-lists/total): top-30 filtered by query keywords, degrading to the raw list when nothing matches.

Expired/invalid cookies degrade to the hot list automatically (warning logged), never error the search.

⚠️ The cookie is a login credential — treat ZHIHU_COOKIE like a password. z_c0 rotates if you log out; re-copy after re-login.

Douban / 豆瓣 (no credentials)

Free, keyless (live-verified 2026-08): keyword search across movies, TV, books, and music via the mobile m.douban.com/rexxar/api/v2/search API with an iOS User-Agent + Referer: https://m.douban.com/ header (both required — the API rejects bare requests). Returns titles with rating value/vote count; canonical per-type URLs (movie.douban.com/subject/..., book.douban.com/subject/...). Ad/smart-box cards are filtered. No trending endpoint (Douban has no public hot-list API). Use Chinese keywords for best results.

WeChat articles / 微信公众号 (via the web source, auto-scoped)

WeChat MP articles are searchable through the existing web source: Searxng indexes them (verified 2026-08, 17 real results for 人工智能). Queries containing 公众号 / 微信文章 / weixin are auto-scoped with site:mp.weixin.qq.com on Searxng — no manual site: needed. There is no dedicated wechat source (WeChat has no public search API; the scraped-token approaches all require desktop mitmproxy).

Web search (SEARXNG_URL)

Required for the web source. Point to your self-hosted Searxng instance (default http://searxng:8080). If you don't have one, Searxng runs easily in Docker.

YouTube (YTDLP_PROXY / YTDLP_COOKIES)

Optional. From a datacenter IP (e.g. the mcpo container), YouTube bot-walls yt-dlp ("Sign in to confirm you're not a bot") and search returns 0 — this is an egress restriction, not a code issue. Two workarounds:

• YTDLP_PROXY — set to a residential proxy URL (e.g. socks5://...). A normal datacenter proxy won't help; only non-datacenter egress bypasses the wall.

• YTDLP_COOKIES — path to a cookies.txt (Netscape format) exported from a logged-in browser, or a browser name (chrome/firefox). See docs/CREDENTIALS.md §9.5 for the export steps.

If neither is set, youtube still works when reach runs from a residential/host IP (e.g. the dev machine).

Digg (digg-pp-cli)

Digg is auto-enabled when the digg-pp-cli binary is on PATH. Built from the last30days project's build steps. Without the CLI, digg stays gated off.

Apify (APIFY_API_TOKEN) -- quora, tiktok, threads, instagram, pinterest, linkedin

Apify's Free plan gives $5 in credits every month (recurring, not one-time) -- enough for hundreds of search runs. One token enables:

• quora -- via the apify/quora-search-scraper Actor (primary path)

• threads -- fallback when the free playwright SSR backend isn't installed

• tiktok / instagram / pinterest -- Apify is the preferred backend

1. Sign up at apify.com (Free plan, no card)

2. Copy your API token from Settings --> Integrations

3. Set APIFY_API_TOKEN=apify_api_...

OpenCLI (optional desktop free) -- tiktok, instagram, pinterest

OpenCLI (Apache--2.0, free) reuses your logged-in Chrome session via a browser bridge. If the opencli binary is on PATH, tiktok/instagram/pinterest use it automatically as a free desktop backend (no API key needed). Desktop-only -- not for headless/Docker deployments.

bilibili (bili CLI)

Prefers the community-vetted bili-cli (uv tool install bilibili-cli) when on PATH -- it handles B站's wbi signing and anti-scraping (HTTP 412) that raw API calls hit. Falls back to the public search API if bili is absent. No login needed for search.

Xiaoyuzhou / 小宇宙

Podcast search + Whisper transcription. Search requires a 小宇宙 account token (phone-SMS login):

1. Login flow: the app sends a code to your phone, which returns accessToken/refreshToken (see xiaoyuzhou-api for the exact flow)

2. Set XIAOYUZHOU_ACCESS_TOKEN=...

3. Transcription uses an OpenAI-compatible Whisper endpoint (WHISPER_BASE_URL, default http://gpu.savorcare.com:8080/v1, model whisper-large). Point it at any self-hosted LocalAI or Groq's api.groq.com/openai/v1 — the API key may be empty if your server doesn't check it.

Audio constraint (Whisper): files ≤ 25 MB, formats mp3/mp4/mpeg/mpga/m4a/wav/webm; no explicit duration cap at the API layer.

read_url tool (Jina Reader)

The read_url(url) tool fetches any URL's content as clean text via r.jina.ai (Jina Reader). Use it to read a page you found in search results -- a Reddit thread, news article, blog post, or GitHub readme -- when you need the full text beyond the snippet. Keyless at 20 RPM; set JINA_API_KEY for 500 RPM (free monthly quota). Returns {url, content, ok}.

Migration from last30days

If you're coming from the last30days MCP server (mvanhorn/last30days-skill), here's what changes:

Env var mapping

Sources: gained and lost

Behavioral differences

• days is per-call, not hardcoded to 30

• sources is per-call, not global INCLUDE_SOURCES

• synthesize=false returns raw scored rows (last30days always synthesizes)

• list_sources shows exactly what's configured and what each source needs

• No INCLUDE_SOURCES global filter -- just pass sources=[...] per search

• No --hiring-signals, --discover, --watchlist -- these were last30days CLI features; reach-mcp is server-only

TikTok + Threads free backends (playwright, optional)

The tiktok and threads sources gain a free, unlimited primary backend when playwright + chromium are installed (live-verified 2026-08):

• tiktok — a headless chromium opens tiktok.com/explore, runs the search as a same-origin in-page fetch (out-of-page HTTP and the TikTokApi library are bot-detected from datacenter IPs; the in-page fetch is not), parses the JSON.

• threads — a headless chromium renders threads.net/search (anonymous sessions get full SSR posts; plain curl gets a login shell) and parses the embedded Relay JSON blob.

Both close the browser before returning — one launch per search, memory fully released between calls (measured: ~0.9GB RSS peak during the search, 0 after).

Enable it in the image (~530MB extra disk, no runtime cost until a search runs):

RUN pip install --no-cache-dir playwright && playwright install --with-deps chromium

Without it the source silently falls back to Apify → OpenCLI → ScrapeCreators as before; the backend order is playwright (free) → Apify → OpenCLI → ScrapeCreators (paid/one-time).
