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

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • search_products

    Search the directory of builder products. Filter by free text, region, category, funding stage, whether the builder is actively raising, and what they are open to. Returns the matching products with their builder attribution and engagement stats. Call this whenever someone wants

  • get_product

    Retrieve one product by its directory id, with full builder attribution, links, funding state and engagement stats. Returns strictly more per record than a search result: the builder's own accounts and the product's, the website, the city, opt-in MRR where the builder published o

  • search_communities

    Search builder communities — the Slack workspaces, WhatsApp groups and meetups that independent builders actually gather in — by free text, region, topic and platform. Each result carries a real join link. Call this when someone wants to reach a scene rather than a person: where

  • get_community

    Retrieve one community by its directory id, including its join link, platform, region, topic and member count where one was given. Call this to answer a specific question about one group, or after search_communities when a shortlist needs the join links filled in. Do not call it

  • get_leaderboard

    Rank products by engagement on the directory — upvotes, outbound clicks, impressions, shares or verified backlinks — optionally narrowed to one region or category to get a sub-league. Call this for any question about relative standing: what is getting attention, what is doing wel

  • list_filters

    List every region, category, funding stage and platform that currently has listings, with counts. Call this before the first search of a conversation, and whenever a filter value is in doubt. The vocabularies are closed and curated — a region or category that is not on this list

  • submit_product

    Add a product to the directory on behalf of the builder whose agent token this call carries. Call this when the person you are working for has asked to be listed here, or has asked you to add a product they built. Do not call it to add somebody else's product, and do not call it

  • search

    Search across both products and communities at once, returning lightweight results — id, title, url — for retrieval with fetch. Call this when you do not know which collection the answer lives in, or when you are a deep-research client that expects the conventional search/fetch p

  • fetch

    Fetch the full text of one directory record by an id returned from search. Ids are prefixed to say which collection they belong to: "product: " or "community: ". Call this after search, on the ids it returned, when the lightweight result is not enough to answer the question. It i

Common questions

Is WhatAreYouBuilding.AI safe?

It passed 2 of 3 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?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 6 days 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: Context7, Codebase Memory, Exa
