Claude Code: ask. ### `add_source` - The name "add_source" says "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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_standing` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_domain` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_profile` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_feed` - The name "create_feed" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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_items` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text What a feed selects, newest first. Page with before_id. ``` ### `follow_feed` - Nothing in its name or description says what it does, so it is counted as a write.

Channels: webpush, email, webhook. ``` ### `match_items` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_items` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Newest items, optionally narrowed to a collection, source or kind. ``` ### `run_source` - The name "run_source" says "run": a word for a change. Description, as the server wrote it: ```untrusted-server-text Fetch a source now instead of waiting for its schedule (needs a key; owner or admin). ``` ### `stats` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text What this deployment holds: collections, sources, items, items added today, feeds. ``` ### `submit_feed` - The name "submit_feed" says "submit": a word for a change. Description, as the server wrote it: ```untrusted-server-text Suggest an RSS or Atom feed for the index. No key needed.

Description, as the server wrote it: ```untrusted-server-text Top-level domains added to or removed from IANA's root, newest first, with the IANA list version each happened in.

Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Only reads (14) Looks things up and changes nothing. Claude Code: allow. ### `find_profile_by_linkedin` - The name "find_profile_by_linkedin" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text The public profile a LinkedIn profile or company URL belongs to (linkedin.com/in/… or /company/…), or null.

Optionally one collection. ``` ### `list_sources` - The name "list_sources" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Sources with status, last run and item counts. Optionally one collection. ``` ### `reputation_lookup` - The name "reputation_lookup" says "lookup": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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_items` - The name "search_items" says "search": a word for reading.

Description, as the server wrote it: ```untrusted-server-text 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_list` - The name "traffic_list" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `nichedb`: ```json { "permissions": { "allow": [ "mcp__nichedb__list_collections", "mcp__nichedb__list_adapters", "mcp__nichedb__list_enrichers", "mcp__nichedb__list_sources", "mcp__nichedb__list_feeds", "mcp__nichedb__search_items", "mcp__nichedb__get_item", "mcp__nichedb__search_profiles", "mcp__nichedb__find_profile_by_linkedin", "mcp__nichedb__get_profile", "mcp__nichedb__search_tlds", "mcp__nichedb__get_tld", "mcp__nichedb__reputation_lookup", "mcp__nichedb__traffic_list" ], "ask": [ "mcp__nichedb__stats", "mcp__nichedb__feed_items", "mcp__nichedb__recent_items", "mcp__nichedb__upcoming", "mcp__nichedb__match_items", "mcp__nichedb__population", "mcp__nichedb__create_feed", "mcp__nichedb__follow_feed", "mcp__nichedb__submit_feed", "mcp__nichedb__claim_profile", "mcp__nichedb__update_profile", "mcp__nichedb__add_source", "mcp__nichedb__run_source", "mcp__nichedb__tld_changes", "mcp__nichedb__check_domain", "mcp__nichedb__business_standing" ], "deny": [] } } ```
