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. Paste the server URL where your app asks for a custom connector or MCP server, and sign in to MarkIt when the browser opens. Best for Claude, ChatGPT web, Cursor, VS Code.

Option 2 - API key. Generate a key in Settings > Integrations (shown once, keep it secret). Best for CLIs, scripts, and the ChatGPT desktop app.

Option 1 - sign in from your app

One-click installs

Everyone else

App	Steps
Claude (claude.ai + Claude Desktop)	Settings > Connectors (under Customize) > Add custom connector > paste `https://mark-it.co/api/mcp` > authorize. Available on all plans (Free allows one custom connector). Known issue: an open Anthropic-side bug can fail the authorization right after you approve - if that happens, use Claude Code (below) until Anthropic ships the fix.
ChatGPT (web)	Settings > Security and login > turn on Developer mode, then Settings > Plugins (or chatgpt.com/plugins) > + > paste the server URL > connect with OAuth.
Claude Code	`claude 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.
Codex CLI	Add the server (see clients/codex.toml, skip the token line) then `codex mcp login markit`.
Zed	Add a `context_servers` entry with just the `url` (see clients/zed.json); Zed prompts you through OAuth when there is no Authorization header.

Option 2 - use your API key

In MarkIt Settings > Integrations, open Connect Your AI and generate your key. It starts with mkt_ and is shown once.
Grab your app's config from clients/ and replace mkt_your_key_here:

App	Config
Claude Code	clients/claude-code.md
Cursor	clients/cursor.json
VS Code	clients/vscode.json
Codex CLI + ChatGPT desktop app	clients/codex.toml (they share `~/.codex/config.toml`)
Windsurf	clients/windsurf.json
Cline	clients/cline.json
Zed	clients/zed.json
Anything stdio-only	clients/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

Tool	What it does
`search`	Plain-language search over your library, with optional filters (category, platform, type, author, tags, dates).
`fetch`	Full stored content of one item by id.
`list_categories`	Your categories with item counts.
`save_item`	Save 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_reminder`	Set or reschedule a reminder on an item (email for everyone; WhatsApp/Telegram on Pro).
`list_reminders`	Your pending reminders.
`cancel_reminder`	Cancel one reminder by id. Never touches the item itself; Google-Calendar-synced reminders stay managed on-site.
`send_feedback`	Send 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: known Anthropic-side bug in claude.ai custom connectors (our server completes the whole OAuth flow; Claude drops it after the token). Use Claude Code or Cursor until it's fixed.
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? [email protected].

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.
