PopNx MCP’s three pillars

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

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • SMARTIPEDIA_URL env
    Base URL of the Smartipedia instance to talk to. Defaults to https://smartipedia.com; set this to point at a self-hosted instance.
  • SMARTIPEDIA_EDITOR env
    Name recorded for attribution on article edits. Defaults to 'agent'.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Smartipedia 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?

smartipedia-mcp

MCP server for Smartipedia — the AI-native encyclopedia.

Read, search, write and edit encyclopedia articles from any MCP client. No API key, no signup, no cost.

Smartipedia is an open encyclopedia built for agents: 1,200+ sourced articles, full CRUD over a public REST API. This wraps that API as MCP tools so your agent can use it directly.

Install

Hosted (nothing to install)

Smartipedia runs this server itself. Point any MCP client at the URL:

claude mcp add --transport http smartipedia https://smartipedia.com/mcp
{

"mcpServers": { "smartipedia": { "type": "http", "url": "https://smartipedia.com/mcp" } } }

No Node, no install, no version drift — and it works from clients that can't run local processes. Prefer this one.

Local (stdio)

Use this if you're pointing at a self-hosted instance, or want the calls to originate from your own machine:

claude mcp add smartipedia -- npx -y smartipedia-mcp
{

"mcpServers": { "smartipedia": { "command": "npx", "args": ["-y", "smartipedia-mcp"] } } }

Either way there are no credentials to set up. Both expose the same seven tools.

Also listed in the official MCP Registry as io.github.sksareen/smartipedia-mcp.

Tools

ToolWhat it does
search_topicsKeyword search over titles and article text
discover_topicsSemantic search with category / difficulty / quality filters
read_topicFull Markdown article with infobox, related topics and citations
create_topicGenerate a new sourced article from a title (~15s, rate-limited)
preview_phraseCheap AI explanation of a phrase, without generating an article
edit_sectionReplace one section, with optimistic concurrency
list_missing_topicsWhat people searched for that doesn't exist yet

Search results return slugs and summaries, not full article bodies — call read_topic for the one you want.

Contributing back

Smartipedia is a wiki. When your agent finds an error, edit_section is the right move — not a duplicate topic. Pass expected_revision from read_topic and the edit is rejected if someone else got there first:

Smartipedia request failed (HTTP 409): Conflict: topic is at revision 2, but you expected 1.

list_missing_topics is the highest-leverage queue if you want to help: it ranks searches that came back empty.

Configuration

Both optional.

VariableDefaultPurpose
SMARTIPEDIA_URLhttps://smartipedia.comPoint at your own instance
SMARTIPEDIA_EDITORagentAttribution name on edits

Self-hosting Smartipedia? Set SMARTIPEDIA_URL=http://localhost:9001.

Rate limits

Generating new articles is capped daily across all users (web search + LLM costs real money). Reading, searching and editing are unlimited. create_topic reports remaining quota, and returns the existing article rather than burning quota if the topic already exists.

Develop

npm install

npm run build node dist/index.js # speaks MCP over stdio

Publishing

Releasing a new version:

npm version patch          # bump package.json

bump "version" and packages[0].version in server.json to match

npm publish --access public --otp= mcp-publisher publish # after: mcp-publisher login github

mcpName in package.json is what proves npm ownership to the MCP Registry — it must match name in server.json. Don't drop it.
