Overview

Description from the maker (original English)

Sources in, feeds out: an open, ever-growing database of real-time public data, enriched.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Common questions

Is NicheDB safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: 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

ThingWhat it is
collectionA niche: games, packages, filings.
sourceOne adapter pointed at one upstream, fetched on its own cadence. Steam's new-releases list. The npm changes feed. EDGAR Form D filings.
itemOne row a source produced. Title, URL, when (with time_known and precision), tags, and the adapter's payload in data.
feedA 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:

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
