Anysite mcp

Anysite MCP — usage guide

The anysite MCP exposes hundreds of data sources through six universal meta-tools (plus the crm_* family, see Working with CRM). This skill is the map: how to call them, which sources cover which GTM need, and how to not waste credits.

The six meta-tools

Tool	Purpose	Credits
discover(source, category)	List endpoints + exact params for a source/category	free
execute(source, category, endpoint, params)	Run an endpoint; returns first 10 items + cache_key	paid
get_page(cache_key, offset, limit)	Page through a cached result	free
query_cache(cache_key, conditions, sort_by, sort_order, aggregate, group_by, limit, offset)	Filter/sort/aggregate cached data with SQL-like ops	free
export_data(cache_key, output_format, list_unpack)	Export cached data — output_format json (default) / csv / jsonl; list_unpack = how many nested-array elements to expand into CSV columns (default 1)	free
search_requests(source, category, endpoint, query, since, until, limit, offset)	Find past execute() calls and their cache_keys — 7-day history, works across sessions	free

Rules that prevent 90% of failures

1. Always discover before execute. Endpoint names and params are not guessable, and a wrong source name returns the full source list — a wrong guess self-corrects for free. execute takes the endpoint NAME exactly as discover returns it (products_reviews), never a REST path segment (reviews) — resolution is an exact-match lookup.
2. Never guess identifiers. LinkedIn aliases, URNs, Crunchbase aliases, Greenhouse board tokens are unpredictable. Resolve them through the search endpoint of the same source first.
3. Re-use the cache — it outlives the session. execute returns a cache_key; further filtering, sorting, counting and paging of that result is free, and the cache lives for 7 days across sessions. Before any paid execute, check search_requests (free) for a recent identical call — same endpoint, matching params — and reuse its cache_key via query_cache/get_page instead of refetching (verified live: a two-day-old cache_key from another session served in full). Freshness rule: reuse when the data's age is fine for the task (enrichment firmographics — usually yes; "what's new today" — no).
4. Cheap-first cascade. When several endpoints can answer, call the cached/DB one first (*/db/*, *sql* endpoints, ~1 credit) and the live one only for the remainder.
5. Estimate volume before bulk runs — plan-aware. First know the user's plan (the CRM profile stores it after setup; if unknown, ask once: MCP Unlimited or credit-based?).
   • Credit-based plan: before anything above ~100 calls, state the estimate (N targets × credits-per-call) and get a nod. Prefer cheap DB endpoints, batch hard.
   • MCP Unlimited: credit warnings off, but keep batch sizes sane anyway — the real limits are latency and upstream rate limits, so cap sweeps the same way and say "this will take ~N minutes" instead of a price.
6. Live LinkedIn search fails as an empty list, not an error. search_users and search_companies return {"results":[]} on queries that just don't hit ("stripe", "databar" both came back empty live, while "microsoft" worked) — it is not a broken key. On empty, switch to the search_sql_* DB endpoints; do NOT retry with broader keywords. (This is why reverse-lookup via live search_users is best-effort, not "usually one match".)
7. gdelt is slow by design, not broken — 10–50s per call is normal (upstream per-IP throttling), and worst cases exceed the MCP client's silent-call timeout, which looks like a hang. Endpoints: gdelt/articles/articles_search and articles_context (timespan like 3d/1w or start_datetime YYYYMMDDHHMMSS; count ≤250). Keep it OUT of per-account sweep loops (use techmeme / google news — seconds); fine for a one-off deep media dive with a "takes a minute" warning.

GTM source map

Company discovery (bulk):

• linkedin/search/search_sql_companies — the workhorse. Up to 1000 companies per call with DSL filters (keywords, industry_name, employee_count_min/max, country_hq, founded_on_min/max, has_website) and a sort param (relevance — default for filtered queries — or last_modified for freshness/monitoring). Also batch lookup by urn and search by website. Query craft (naive keywords return wrong-country token soup — measured 1/5 relevant vs 5/5 structured): the anysite-company-sourcing skill. ⚠️ website search is SUBSTRING match, ordered by last_modified. Verification is MANDATORY on every resolve — position in the results means nothing. Verified live: {website: "stripe.com", count: 1} → Soundstripe; {website: "stlabs.com", count: 5} → five *labs.com companies, none of them stlabs.com (common tokens flood the result even in a single-domain call). The domain-resolve rules:
  1. Verify exact website match (normalize both sides: lowercase, strip protocol/www./path) on EVERY resolve, single or batched. No exact match = unresolved — never write anything to the CRM for it; wrong-company data lands in blank fields where nobody will catch it.
  2. Never count: 1 on a website resolve — the substring flood means the one row you get is very likely the wrong company. Default one domain per call at a small count (5+). OR-DSL batching ({website: "a.com|b.io", count: 10× domains}) is an optimization with a verification tax: a domain with a common token can be flooded out of the batch entirely — every domain that didn't come back exact-matched must be re-queried individually.
  3. query_cache filters over the WHOLE cached set (verified) but returns at most limit rows (default 10) — pass an explicit limit when you expect more matches back. Sanity rule: aggregate {op: "count"} should equal the total from execute; if not, page with get_page before concluding anything.
  4. A whole class of domains never appears in its own substring results (common-token domains like stlabs.com) — so the website's own page is the STANDARD second step, not an emergency: webparser/parse {url: "https://<domain>", extract_minimal: true} → top-level title says who they are, links[] usually carries their own linkedin.com/company/... URL → linkedin/company for the exact URN (verified, ~1cr). Live shape on stlabs.com: title: "STLabs — Intelligent Service Management" at the TOP level, while metadata came back {} and cleaned_html empty — read title, and treat metadata as a fallback only, not the primary location. Secondary fallback: crunchbase/search by name → contacts.linkedin_url. Name search alone is never a source of truth. Bonus from a successful resolve: the search_sql_companies row already carries crunchbase_link (free crunchbase alias — skip the live 20cr search) and organizational_urn (company:<id> — the numeric id goes straight into search_jobs). ⚠️ For company SIZE use employee_count, never employee_count_range — the two fields can contradict each other in the same record (verified: Clay returns employee_count: 1465 alongside employee_count_range: "201-500"). The range field looks like the natural key for size segmentation and would misfile that company by ~3x, silently. Fall back to the range only when the exact count is empty, and say that you did.
• crunchbase/db/db_search — filters by funding stage, last funding date, investors, employee range; count ≤100, dates as Unix timestamps. employee_count_min/max are ENUM bands, not free integers (min ∈ {1,11,51,101,251,501,1001,5001,10001}, max ∈ {10,50,100,250,500,1000,5000,10000,10001}) — passing 20 errors out. 1 credit/result. Response includes funding_rounds[], leadership_hires[], layoffs[], news[], technologies[], employees[].
• crunchbase/search (live, 20cr/50) — adds hiring, event, spotlight, shares_investors_with, it_spend_*, revenue_*, valuation_* filters. Check discover for its date format — it differs from db_search.
• Early-stage supplements: yc/search/search_companies (keyword search, works) and betalist/startups/startups_search {keyword, count}. NOT tracxn/companies/companies_search — it has no name/keyword input, only an explore param (a URL/id of a ready-made Tracxn list) and returns guests only a truncated slice; usable solely if you already hold such a list URL.

Company detail: crunchbase/company — get its alias for free from the crunchbase_link that search_sql_companies already returned (live crunchbase/search is the fallback, not the first step). ⚠️ The alias is CASE-SENSITIVE ('Google' ≠ 'google') — take it verbatim from the URL slug. Also linkedin/company. One crunchbase/company call carries free extras: bombora_surges[] (B2B intent topics — but they show what THAT company's staff researches, i.e. what they BUY; treat as a signal only when a topic matches what the user sells), related.competitors[], predictions.funding_score, awards[]. Coverage caveat: leadership_hires[] is often EMPTY for smaller companies — absence of the field is not absence of hires. Normalize contacts.email (trailing dots observed: "[email protected]."). A third resolve path when crunchbase is already fetched: contacts.linkedin_url → linkedin/company → exact URN (verified; bypasses both fuzzy searches). Note: owler endpoints need an owler alias and its search has no name/keyword parameter — not usable for looking up a named account.

Engagement graph (who interacted with content): linkedin/post/post_comments, post_reactions, post_reposts and linkedin/company/company_posts (~1cr/10) — answers "who paid attention to this content", incl. people outside your title filters. Identifiers: comments/reposts carry a vanity alias; reactions give only an obfuscated /in/ACoAA... URL plus internal_id — user_email accepts the internal_id, never the obfuscated URL. Honest scaling: volume follows the SEED's audience, not the target's importance (large brand post → dozens of engagers; 80-person company → 0–2 per post), and on a small account those few are mostly the company's OWN staff plus engagement farmers (verified: 3 of 4 commenters were employees) — filter by the author's company first and expect nothing left. Use this on seeds with a real audience (a competitor's page), not on SMB target lists. For small accounts the reliable nugget is company_posts → mentioned[]: hiring announcements name new people with their vanity aliases. linkedin/company/company_employee_stats (1cr) gives function/skill/location breakdown — cross-check totals against employee_count from linkedin/company before trusting absolutes, and never sum the locations array: its buckets are nested (US ⊃ California ⊃ SF Bay Area), so summing double-counts badly. Its llm_hint promises seniority and growth trends that the response does not contain.

Tech stack & adoption signals: stackshare/companies (a company's declared stack by slug — the forward direction wappalyzer can't do); producthunt/products/products_customers (reverse stack: who uses a product, with a testimonial quote — a budget/intent tell). There is NO ad-transparency source in the catalog (verified: not among the 591 sources, and linkedin has no ads category) — do not reach for ad-library data, it isn't here.

People:

• linkedin/search/search_sql_users — the 856M-profile DB, the bulk workhorse: derived seniority/function filters, company domain/id (incl. past employers = alumni), career-shape (months_in_role, tenure, promotions), lookalike graph (similar_to), deterministic buckets for >1000. Craft guide: the anysite-people-sourcing skill. Key semantics: over-count result is an unbiased SAMPLE (repeat = same people; walk bucket_total/bucket_index instead), and has_* flags make coverage narrowing explicit — set them when filtering by fields not every profile states.
• linkedin/search/search_users (live) — one-off lookups and namesake disambiguation (job_title + current_company/company_keywords; never bare keywords alone).
• linkedin/user (full profile, needs alias/URL/URN — never guess the alias), linkedin/user/user_posts, user_experience, user_comments.

Email finding (cascade, cheap → expensive):

1. linkedin/user/user_email — batch up to 10 profiles, cheap, low yield. Truths from live testing: it returns a MIX of personal and work addresses (roughly half and half), one row per EMAIL — not per profile — and a single person can come back with several rows, including emails at PAST employers (measured: one alias → 4 rows spanning current and former company domains). Its found field is always true (useless as a check). So: group by alias/internal_id, then match the domain against the person's CURRENT company; if more than one work address survives, treat it as unverified and pass to step 2. Personal addresses are not outreach-ready.
2. linkedin/user/user_find_email_by_url {url} — high yield but expensive (50cr), run only on the remainder after step 1. Takes a VANITY profile URL (/in/satyanadella/); URN-style URLs (/in/ACoA...) are rejected — get the vanity URL from linkedin/user first. Response includes email_status and valid_email — check them and pass only valid work emails onward; an address with a bad status is a bounce, not a find.
3. No work email found → keep the lead anyway; CRM contact upserts match by linkedin_url too (but note: creating a NEW contact requires an email — no email means update-only).

Reverse lookup (email → person), reliability order:

1. linkedin/email/email_sql_user (cached DB) → email_user (live) — cheap, but verified to return empty even for people who are definitely on LinkedIn. Try, don't rely.
2. The cascade that works when you know the name (a CRM does): email domain → resolve the company (verified, see above) → organizational_urn → search_users {first_name, last_name, current_company: [{"type": "company", "value": "<id>"}]} → usually exactly one match, delivered WITH the fsd_profile URN needed for user_posts. The company filter is mandatory — a bare name returns namesakes.

Hiring signals:

• linkedin/search/search_jobs — by company; works for any company. The company param takes [{"type": "company", "value": "<numeric id>"}]. linkedin/search/search_companies returns urn ALREADY in that object form — pass it through as-is. Only search_sql_companies returns string URNs (fsd_company:<id>) — there, extract the numeric id yourself. And verify the company before using its URN: the first search hit is often a namesake (verified: "Notion" → NOTION Media Production first, the real notionhq second) — check name + industry + alias.
• greenhouse/jobs/jobs_search {board_token, count} — full descriptions via content=true; ashby/jobs/jobs_search {board_name, count} — descriptions always included. Both need the company slug; 412 = wrong token, fall back to linkedin jobs.
• glassdoor (resolve employer id via companies_search first), builtin, adzuna — supplements; blind/layoffs/layoffs_search for layoffs.

Tech stack: wappalyzer/technologies — technology slug → who uses it (top_websites sample), category alternatives (alternatives[]), country/language breakdown. Note: it is a sample, not an exhaustive site list.

Software reviews: g2/products/products_search (search only), capterra/products/products_reviews (includes switched_from[] and switching_reason — direct competitor-switch evidence), trustradius and getapp products_reviews, gartner/products — competitor review mining. Employer sentiment: glassdoor/companies/companies_ratings (employer id via companies_search), kununu (DACH only — country ∈ de/at/ch), comparably, blind/companies/companies_reviews (+ companies_salaries comp percentiles, companies_posts anonymous chatter).

News & mentions: techmeme/stories/stories_search {keyword, count} (archive) and stories_front_page; google/news/news_articles_search; linkedin/search/search_posts (keyword or mentioned company URN; date_posted accepts only past-24h / past-week / past-month); reddit, hackernews, twitter, bluesky for community chatter; substack/medium for content signals.

Launches & products: producthunt/launches/launches_search, producthunt/products/products_alternatives, products_reviews; indiehackers, kickstarter/indiegogo for niche ICPs.

Web fallback: webparser/parse (static pages) → webparser/render (JS-rendered). Covers any URL when no named source fits. Web search: duckduckgo/search, brave/search.

Combining into signal chains

The standard pattern for account signals (used by the crm-signals skill):

company domain
  → search_sql_companies {website} + exact verify        (firmographics
     ↳ crunchbase_link → alias FREE   ↳ organizational_urn)
  → crunchbase/company {alias} → funding_rounds, leadership_hires, news, layoffs, bombora
  → search_jobs {company: [{type, value from organizational_urn}]} → what they hire for
  → search_posts (company name, past-month) → mentions

Four paid calls per account instead of five — the live crunchbase/search drops out (the alias comes free from crunchbase_link); five if the domain doesn't resolve and webparser is needed.

Stack signals: one signal is a guess, 2–3 signals within ~30 days is a pattern worth acting on.

Working with CRM

CRM read/write goes through the crm_* tools, NOT through execute. Before any CRM write, consult the anysite-crm-profile skill (field mapping law) and the Writing rules in anysite-crm-setup. The server enforces fill-blank policy, protected fields and write logging regardless of what you pass.
