Changes things 16Creates or changes something that can be changed back.Claude Code: ask

add_sourceAdd a source: an adapter with a config, fetched on a schedule (needs a key; admins and Pro).No findings
Why it is in this group
- The name "add_source" says "add": a word for a change.
Description, as the server wrote it
Add a source: an adapter with a config, fetched on a schedule (needs a key; admins and Pro). Call list_adapters first for the fields.
business_standingIs a business on anybody's list?No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Is a business on anybody's list? Give its `name`, and any of `domain`, `state` (two letters), `number` (state entity number) and `ein`. Answers with `standing` (flagged, incomplete or clear; clear only when every list was checked and found nothing), the `findings` behind it, and each section: US Treasury OFAC sanctions (SDN and consolidated, aliases included), GLEIF LEI records, SEC EDGAR filers, state registry status (OpenCorporates) and SAM.gov exclusions when keyed, and the domain over RDAP plus Spamhaus/URIBL/SURBL/Safe Browsing when the operator enabled them. A name match is not an identity: confirm against address and identifiers.
check_domainIs a domain name registered?No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Is a domain name registered? Asks each registry over RDAP. Give `name` as a full name (foo.watches), or a bare word with `tlds` (foo + com,dev,io), or several names comma separated. Each answer is registered (with registrar and expiry), not_registered, or unknown. not_registered means the registry holds no registration; the name may still be reserved or premium, so it is not a promise that it is for sale. unknown (no RDAP server, a timeout, a 429) is never a yes. Each answer carries the cheapest known USD price for its ending.
claim_profileClaim a profile as the key owner (needs a key).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Claim a profile as the key owner (needs a key). Proven when the key owner’s email is one the profile lists, or when the person’s site or show page links back to the profile’s nichedb page. An admin may claim on behalf of an email.
create_feedSave a query as a feed (needs a key).No findings
Why it is in this group
- The name "create_feed" says "create": a word for a change.
Description, as the server wrote it
Save a query as a feed (needs a key). Sources, kinds and tags narrow; q is a text match; upcoming keeps only future-dated items.
feed_itemsWhat a feed selects, newest first.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
What a feed selects, newest first. Page with before_id.
follow_feedFollow a feed as the key owner (needs a key).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Follow a feed as the key owner (needs a key). Channels: webpush, email, webhook.
match_itemsWhich title, channel or fixture is this name?No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Which title, channel or fixture is this name? Give a file name, a release name or a playlist entry ("Top.Gun.Maverick.2022.1080p.mkv", "US: ESPN2 HD"); it is cleaned (year, season and episode, quality tags, playlist decorations) and matched by similarity. A matchup ("NFL: Chiefs vs Bills", "Lakers @ Celtics", "Rangers at Celtic 19:45") is answered by the fixture whose two teams those are, kicking off between 36 hours ago and 7 days ahead unless date narrows it. Each result carries a score in 0..1. Use screen for films and TV, channels for television channels, sports for fixtures.
populationPopulation and demography, drilled down from the world to the ZIP code.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Population and demography, drilled down from the world to the ZIP code. Give a `key` (us, us-ca, us-ca-los-angeles, gb, gb-england-london), a US `zip`, or a place name in `q`; no argument is the world. Answers with the area (population, year, measures: age, income, home value, rent, poverty, education, unemployment, race and Hispanic origin for the US; growth, age structure, births, deaths, fertility, life expectancy, migration, GDP per head and Gini for countries), how many areas of each level it contains, and the largest of its children at `level` (country, state, city or zip). Sources: World Bank, US Census ACS 5-year, GeoNames.
recent_itemsNewest items, optionally narrowed to a collection, source or kind.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it

Why it is in this group
- The name "submit_feed" says "submit": a word for a change.
Description, as the server wrote it
Suggest an RSS or Atom feed for the index. No key needed. An admin reviews every suggestion before anything is fetched; approved podcast feeds are handed to rssamplifier, everything else becomes a source here.
tld_changesTop-level domains added to or removed from IANA's root, newest first, with the IANA list version each happened in.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.

Edit a profile you own (needs a key). Send `markdown`, a whole OpenProfile.md that replaces what you wrote before, or any of `name`, `headline`, `emoji`, `pronouns`, `web`, `identity` (key: value, null removes), `sections` (name: body, `none` removes), `handle`, `public`. What you write wins over every source and survives every re-read.

- The name "get_tld" says "get": a word for reading.
Description, as the server wrote it

list_adaptersEvery adapter this deployment can run, with the config fields each takes.No findings
Why it is in this group
- The name "list_adapters" says "list": a word for reading.
Description, as the server wrote it
Every adapter this deployment can run, with the config fields each takes. Use before add_source.
list_collectionsThe collections (niches) with their source, feed and item counts.No findings
Why it is in this group
- The name "list_collections" says "list": a word for reading.
Description, as the server wrote it
The collections (niches) with their source, feed and item counts.
list_enrichersEvery enricher (YouTube videos, Wikipedia, repo stats, downloads, company profiles, TL;DRs) and which collections turn it on by default.No findings
Why it is in this group
- The name "list_enrichers" says "list": a word for reading.
Description, as the server wrote it
Every enricher (YouTube videos, Wikipedia, repo stats, downloads, company profiles, TL;DRs) and which collections turn it on by default. Items carry their results under `enrichment`.
list_feedsPublic feeds, most followed first.No findings
Why it is in this group
- The name "list_feeds" says "list": a word for reading.
Description, as the server wrote it

reputation_lookupIs an IP address or a domain on a blocklist?No findings
Why it is in this group
- The name "reputation_lookup" says "lookup": a word for reading.
Description, as the server wrote it
Is an IP address or a domain on a blocklist? Give `indicator` (an IPv4/IPv6 address or a domain; a URL is reduced to its host). Answers `listed`, a rough 0-100 `score` with the `reasons` behind it, the nichedb /traffic record (addresses our own servers banned and a person approved), the abuse.ch indicators (ThreatFox, URLhaus, Feodo Tracker; a domain is checked with its parent domains), the SURBL standing of a watched domain, and live DNS blocklists in `dnsbl` (an address: Spamhaus ZEN with SBL/CSS/XBL/PBL decoded, SpamCop, PSBL, Mailspike; a domain and its parents: Spamhaus DBL, URIBL, SURBL). A domain is also resolved and each A/AAAA address is checked the same way, in `addresses` (each with `ip`, `listed`, `traffic`, `indicators`, `dnsbl`). A list whose own test entry failed is named in `unknown`, not treated as a miss. Not listed is not the same as clean.
search_itemsFull-text search over titles, summaries and tags.No findings
Why it is in this group
- The name "search_items" says "search": a word for reading.
Description, as the server wrote it
Full-text search over titles, summaries and tags. Use this first when you know a name.
search_profilesPeople: one entry per person assembled from every app that serves their OpenProfile.md (podcasters from p0dcasters, public profiles from OutreachGraph).No findings
Why it is in this group
- The name "search_profiles" says "search": a word for reading.
Description, as the server wrote it
People: one entry per person assembled from every app that serves their OpenProfile.md (podcasters from p0dcasters, public profiles from OutreachGraph). Search by name, headline or anything in the document; newest change first. Each answer carries the page, the openprofile.md URL, accounts, topics, Broadcast shows, the Guest section, and the job title, company and seniority the person published (filter on them with title, company, seniority or tags).
search_tldsTop-level domains: every label in IANA's root, with type, registry, RDAP server and each registrar's one-year register/renew/transfer price (Porkbun, Dynadot, Cloudflare, OVHcloud)…No findings
Why it is in this group
- The name "search_tlds" says "search": a word for reading.
Description, as the server wrote it
Top-level domains: every label in IANA's root, with type, registry, RDAP server and each registrar's one-year register/renew/transfer price (Porkbun, Dynadot, Cloudflare, OVHcloud). Sorted by renewal by default, because the first year is a promotion. `best` is the cheapest USD price across registrars; with `registrar` it is that registrar's own price in its currency. Answers carry facet counts. `trap: true` keeps only labels that renew at 2x the first year or more.
traffic_listThe nichedb /traffic blocklist: IP addresses our own servers banned for exploit attempts, scanning, brute force or spam, each published only after a reviewer (a person, or riotcode…No findings
Why it is in this group
- The name "traffic_list" says "list": a word for reading.
Description, as the server wrote it
The nichedb /traffic blocklist: IP addresses our own servers banned for exploit attempts, scanning, brute force or spam, each published only after a reviewer (a person, or riotcoder applying published rules) read the evidence and approved it. Newest approvals first. Optional `days` keeps addresses seen in the last N days, `category` one of exploit, brute-force, scanner, spam, other. Without an API key the newest 100 are returned; with one, `limit` (up to 1000) and `offset` page the whole list.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

16 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
