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.

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.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save

Common questions

Is MarkIt 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?

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 (0.1.0) reached the registry 4 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?

MarkIt MCP - connect your AI to your library

Bring your own AI. MarkIt is the memory.

[!TIP]

The lazy path (recommended): paste this repo's URL into your AI and say "connect me to MarkIt". It reads llms.txt and handles everything below for you.

MarkIt saves the links, posts, and notes you'd otherwise lose, and makes them searchable in plain language. This repo is the official guide for connecting your own AI - Claude, ChatGPT, Cursor, and friends - to your MarkIt library over the open Model Context Protocol.

Once connected, your AI can search your library, read what it finds, save new things into it, and set reminders. In your words, not keywords.

Server URL:  https://mark-it.co/api/mcp

Transport: Streamable HTTP Auth: OAuth 2.1 (sign in) or a personal API key (mkt_...)


Pick your path

Option 1 - Sign in (OAuth). No key to handle. Works with Claude, ChatGPT web and Claude Code only: MarkIt refuses sign-in from any other app, so a look-alike app cannot trick you into signing in.

Option 2 - API key. Generate a key in Settings > Integrations (shown once, keep it secret). For every other app: Cursor, VS Code, Codex CLI, Windsurf, Cline, Zed, scripts, and the ChatGPT desktop app.


Option 1 - sign in from your app

AppSteps
Claude (claude.ai + Claude Desktop)Settings > Connectors (under Customize) > Add custom connector > paste https://mark-it.co/api/mcp > Connect > sign in to MarkIt > Allow. Available on all plans (Free allows one custom connector).
ChatGPT (web)chatgpt.com/plugins > + > Add custom MCP server. Icon: upload the MarkIt icon (optional, keeps the MarkIt logo in your plugin list instead of a puzzle piece). Name: MarkIt. Server URL: https://mark-it.co/api/mcp. Authentication: OAuth. Tick I understand and want to continue > Create as a plugin > sign in to MarkIt > Allow.
Claude Codeclaude mcp add --transport http markit https://mark-it.co/api/mcp then run /mcp in a session and pick Authenticate. Add --scope user to use it in every project.

Any other app: use Option 2.

Option 2 - use your API key

  1. In MarkIt Settings > Integrations, open Connect Your AI and generate your key. It starts with mkt_ and is shown once.
  2. Grab your app's config from clients/ and replace mkt_your_key_here:
AppConfig
Claude Codeclients/claude-code.md
Cursorclients/cursor.json
VS Codeclients/vscode.json
Codex CLI + ChatGPT desktop appclients/codex.toml (they share ~/.codex/config.toml)
Windsurfclients/windsurf.json
Clineclients/cline.json
Zedclients/zed.json
Anything stdio-onlyclients/mcp-remote.json

Rules of the key: one per account, treat it like a password, never paste it into a chat, revoke or regenerate anytime in Settings.


What your AI gets

ToolWhat it does
searchPlain-language search over your library, with optional filters (category, platform, type, author, tags, dates).
fetchFull stored content of one item by id.
list_categoriesYour categories with item counts.
save_itemSave a URL or a text note into your library. MarkIt scrapes, categorizes, and indexes it. Each save spends one monthly capture; re-saving a URL you already have is a free no-op.
create_reminderSet or reschedule a reminder on an item (email for everyone; WhatsApp/Telegram on Pro).
list_remindersYour pending reminders.
cancel_reminderCancel one reminder by id. Never touches the item itself; Google-Calendar-synced reminders stay managed on-site.
send_feedbackSend a short note straight to MarkIt's founder - only when you ask it to. A real person reads every one. Max 3 a day.

What it can NOT do, by design: delete items, edit your account, touch anyone else's data. Saved page content is treated as data, never as instructions.

Privacy, in one breath

Your AI talks to MarkIt with your identity and only ever sees your items. Whatever AI you connect (Claude, ChatGPT, ...) is your own tool under its own terms - MarkIt does not send your library anywhere on its own. OAuth grants are revocable from your AI app; the API key is revocable in Settings. Full details: Privacy Policy.

Troubleshooting

  • 401 right after connecting with a key: the header must be exactly Authorization: Bearer mkt_... - check for a lost space or a truncated key (regenerating in Settings invalidates old keys).
  • Windsurf: the remote-server field is serverUrl, not url.
  • Cline: set "type": "streamableHttp" explicitly.
  • VS Code says it cannot start the server: an entry with a url also needs "type": "http".
  • Claude says "Authorization with MarkIt failed" right after you approve: retry once. If it fails again, use Claude Code (Option 1) or any app with an API key (Option 2). An older Anthropic-side bug caused this; claude.ai sign-in worked again in our test on 2026-10-21.
  • "This app is not supported. Use an API key instead.": sign-in is limited to Claude, ChatGPT web and Claude Code. Use an API key (Option 2).
  • Sign-in window never comes back: finish the login in the browser tab it opened, then retry from the app; some apps need a retry after the first authorize.
  • `mcp-remote` shim: keep it current (mcp-remote@latest; versions before 0.1.16 have a known critical vulnerability). No space around the colon in Authorization:${AUTH_HEADER} on Windows.
  • Still stuck? support@mark-it.co.

For your AI

Point your assistant at llms.txt - a plain-text playbook that teaches it to connect you and to use the tools well. Same file, branded URL: mark-it.co/mcp/llms.txt.

Claude Code users can go one step further: copy the skill/ folder into .claude/skills/markit/ and Claude picks up the full MarkIt usage playbook (when to search vs save, note etiquette, reminder handling) automatically.
