常见问题
NicheDB 安全吗？
它在 1 项适用的基础检查中通过了 1 项。我们没有阅读代码。在添加密钥或令牌之前，请先看看这个服务器要求哪些权限，并使用只具备所需权限的密钥。
它需要哪些密钥或代码？
注册中心没有列出必需的密钥，不过有些服务器会在首次使用时要求你登录。
它在我的电脑上运行还是在云端？
两种方式都可以：安装在你的电脑上，或者连接云端版本。
它还在维护吗？
GitHub 仓库最后更新于–，最新版本（0.1.0）于2个月前进入注册中心。
哪些应用可以使用它？
支持 MCP 的应用，例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接，所以接受远程 MCP 服务器的应用也可以使用，例如开启开发者模式的 ChatGPT。
有什么可以替代它？
同一分类中有：Supabase, MongoDB MCP Server, Elasticsearch MCP Server

NicheDB
Sources in, feeds out. An open platform for databases that only ever grow: game releases, package registries, government filings, and any other public data with a big seed and daily growth. One Postgres, one Redis, and every row reachable by web, RSS, JSON, API, CLI and MCP.
The first deployment is nichedb.dev. Run your own on anything that has Postgres and Redis.
The model
| Thing | What it is |
|---|---|
| collection | A niche: games, packages, filings. |
| source | One adapter pointed at one upstream, fetched on its own cadence. Steam's new-releases list. The npm changes feed. EDGAR Form D filings. |
| item | One row a source produced. Title, URL, when (with time_known and precision), tags, and the adapter's payload in data. |
| feed | A saved query over a collection. Has a page, RSS and JSON Feed renderings, an API endpoint, and followers who are told when it changes by push, email or signed webhook. |
Adapters are one file each in packages/adapters/src. One hundred and sixty-one ship today across forty-six collections:
| Collection | Adapters | Key needed |
|---|---|---|
| games | steam, steam-news, igdb, igdb-catalog (every game IGDB knows, walked by id then kept current from updated_at), wikidata-games, steam-catalog | IGDB only (Twitch client) |
| packages | npm, pypi, crates, go-modules, huggingface, github-releases (runtimes and frameworks, and NIST's own software under usnistgov as github-releases-nist) | no (GitHub token optional) |
| filings | edgar, federal-register | no |
| law | courtlistener (the newest opinions from the Atom feeds: all courts plus each court's own feed in rotation, or one court), courtlistener-oral-arguments (the podcast, with the MP3), courtlistener-api (dockets, judges and financial disclosures, one request a run inside the free tier's 125 a day), courtlistener-catalog (every court, judge with education and party, disclosure with what it reports, oral argument, opinion cluster with its reporter citations as tags, and the FJC database, from the quarterly bulk dumps; dockets opt-in) | COURTLISTENER_TOKEN for the API sources only; the feeds and the dumps are keyless and public domain |
| music | musicbrainz, musicbrainz-catalog, discogs-catalog | no |
| books | openlibrary, gutenberg-catalog, librivox-catalog, openlibrary-catalog | no |
| tabletop | scryfall-sets, scryfall-cards | no |

| outages | statuspage (any Statuspage host) | no |
| extensions | firefox-addons, vscode-extensions | no |
| health | openfda-recalls, clinical-trials | no |

| threats | openthreat (ThreatCrush first; any reporter serving /.well-known/openthreat.json), nvd (every CVE, by lastModified every 15 minutes; "This product uses the NVD API but is not endorsed or certified by the NVD"), surbl (the SURBL lists as a catalogue, and the domains you name looked up in multi.surbl.org; free DNS lookups under SURBL's usage policy, the whole list is only sold as a feed) | no (NVD_API_KEY optional, ten times the rate) |
| profiles | openprofiles (p0dcasters and OutreachGraph listings first; any app that lists the OpenProfile.md files it serves), sportarr-persons (Sportarr's 111k names, kept only when Wikidata knows the person as a human with a sport, with their socials), sportsdb-players, installmap-yc-people (YC companies that run an MCP server, as organizations with their accounts, and their founders) | no |
The way out (OpenSaaS)
nichedb serves its own OpenSaaS descriptor at /.well-known/opensaas.json: the plans as the checkout sells them (prepaid terms, none renews itself) and the actions that are real here, each as the page a person opens and the endpoint an agent calls with an OpenAccess bearer: subscribe (POST /api/v1/billing/subscribe, answers pending with the checkout page), cancel (POST /api/v1/billing/cancel, one click, today, nothing refunded), unsubscribe (a page: /settings, where the follows that send mail are turned off), export (POST /api/v1/account/export, one JSON document at once), delete (POST /api/v1/account/delete, confirmed by a link to the account email, immediate, nothing kept). The same doors as pages: /account/billing, /account/export, /account/delete. The opensaas adapter reads other services' descriptors into the saas collection, one row per plan with the service's own steps and confirm for the way in and the way out shown beside each other.
People (/c/profiles)
One entry per person, assembled from every app that serves their OpenProfile.md. The openprofiles adapter pages each app's listing (/api/openprofiles?since=…), fetches every document from the host that listed it, and merges documents that share an identity key (the Web URL, any Accounts URL, Email, DID) into one profile; a shared name alone never merges. The page is /c/profiles/ - (the id resolves, the name is cosmetic, a wrong name 301s) or /c/profiles/ once the owner took one, and …/openprofile.md next to it is the file, text/markdown, CORS open, with on the page.
A person claims their entry with This is me (proven by the email the profile lists, or a link back to the page from their site or show; admins may claim for an email) and edits it from the page, PUT /api/v1/profiles/ (JSON overlay or a whole text/markdown file), nichedb profile edit, or the update_profile MCP tool, with a session, an API key, or an OpenAccess token carrying openprofile:edit. What the owner writes is an overlay that wins over every source and survives every re-read; a section written as none is removed. The Broadcast and Guest sections (OpenBroadcast, OpenGuest) are what the podcasters and guests feeds cut on.
The page shows the three identity fields OpenProfile 0.4 makes defaults, read from the Markdown: Emoji (one grapheme or an OpenEmoji :shortcode:) beside the name, Pronouns as written beside the handle (absent is unstated, never inferred), and Web (with Website, Homepage and Site read as the s
