このMCPでできること

Aggregates scheduled public-data sources into searchable collections, enriched items, profiles, feeds, and future-event listings.

add_source
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.
入力スキーマ
{'type': 'object', 'required': ['adapter'], 'properties': {'name': {'type': 'string', 'description': 'Display name'}, 'config': {'type': 'object', 'description': 'Adapter config fields'}, 'adapter': {'type': 'string', 'description': 'Adapter name, e.g. github-releases'}, 'collection': {'type': 'string', 'description': "Collection slug; defaults to the adapter's"}, 'cadence_minutes': {'type': 'integer', 'description': '5 to 1440'}}}
check_domain
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.
入力スキーマ
{'type': 'object', 'required': ['name'], 'properties': {'name': {'type': 'string', 'description': 'foo.watches, or foo, or a.com,b.dev'}, 'tlds': {'type': 'string', 'description': 'Endings to try a bare word under, comma separated (optional)'}}}
claim_profile
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.
入力スキーマ
{'type': 'object', 'required': ['ref'], 'properties': {'ref': {'type': 'string', 'description': 'Profile id, slug-id or handle'}, 'email': {'type': 'string', 'description': 'Admins only: claim it for this email'}}}
create_feed
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.
入力スキーマ
{'type': 'object', 'required': ['collection', 'name'], 'properties': {'q': {'type': 'string', 'description': 'Text match'}, 'lat': {'type': 'number', 'maximum': 90, 'minimum': -90, 'description': 'Query center latitude; requires long'}, 'bbox': {'type': 'string', 'description': 'west,south,east,north; west > east crosses the antimeridian'}, 'long': {'type': 'number', 'maximum': 180, 'minimum': -180, 'description': 'Query center longitude; requires lat'}, 'name': {'type': 'string', 'description': 'Feed name'}, 'sort': {'enum': ['id', 'published', 'updated', 'distance'], 'type': 'string'}, 'tags': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Tags, any match'}, 'unit': {'enum': ['km', 'mi'], 'type': 'string', 'description': 'Default km'}, 'kinds': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Item kinds'}, 'public': {'type': 'boolean', 'description': 'Default true'}, 'radius': {'type': 'number', 'description': 'Default 10; maximum 1000 km', 'exclusiveMinimum': 0}, 'sources': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Source slugs'}, 'upcoming': {'type': 'boolean'}, 'enrichers': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Enrichers to show; omit for the collection defaults'}, 'collection': {'type': 'string', 'description': 'Collection slug'}, 'description': {'type': 'string', 'description': 'Optional'}}}

What a feed selects, newest first. Page with before_id.

入力スキーマ
{'type': 'object', 'required': ['id'], 'properties': {'id': {'type': 'integer', 'description': 'Item id'}}}
get_profile
One person by id, `<slug>-<id>` or handle: the parsed view and the OpenProfile.md as served.
入力スキーマ
{'type': 'object', 'required': ['ref'], 'properties': {'ref': {'type': 'string', 'description': 'Profile id, slug-id or handle'}}}
get_tld
One top-level domain: type, registry, RDAP server, when it entered or left the root, every registrar price (register, renew, transfer, restore, promotions, privacy, restrictions) and its change history.
入力スキーマ
{'type': 'object', 'required': ['tld'], 'properties': {'tld': {'type': 'string', 'description': 'The label, with or without the dot; Unicode or xn-- both work'}}}

{'type': 'object', 'properties': {}}
list_collections
The collections (niches) with their source, feed and item counts.
入力スキーマ
{'type': 'object', 'properties': {}}
list_enrichers
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`.
入力スキーマ

list_feeds
Public feeds, most followed first. Optionally one collection.
入力スキーマ
{'type': 'object', 'properties': {'collection': {'type': 'string', 'description': 'Collection slug'}}}

入力スキーマ
{'type': 'object', 'properties': {'collection': {'type': 'string', 'description': 'Collection slug, e.g. games'}}}
match_items
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.

population
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.

Newest items, optionally narrowed to a collection, source or kind.

run_source
Fetch a source now instead of waiting for its schedule (needs a key; owner or admin).
入力スキーマ
{'type': 'object', 'required': ['source'], 'properties': {'source': {'type': 'string', 'description': 'Source slug'}}}
search_items
Full-text search over titles, summaries and tags. Use this first when you know a name.

search_profiles
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 and the Guest section.
入力スキーマ

search_tlds
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.

stats
What this deployment holds: collections, sources, items, items added today, feeds.
入力スキーマ
{'type': 'object', 'properties': {}}
submit_feed
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_changes
Top-level domains added to or removed from IANA's root, newest first, with the IANA list version each happened in. Nobody else publishes this diff.
入力スキーマ

upcoming
Items dated in the future (releases, launches, deadlines), soonest first.

update_profile
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`, `identity` (key: value, null removes), `sections` (name: body, `none` removes), `handle`, `public`. What you write wins over every source and survives every re-read.
