Model Context Protocol (MCP) is an open standard introduced by Anthropic in 2024 for connecting AI assistants to external tools and data sources. A host (Claude, ChatGPT, Gemini, Cursor) speaks MCP to a server (HippoKit), and the host's assistant can then call the server's tools as part of its conversation. It's like a USB port for AI assistants.

Which hosts can connect to HippoKit?

HippoKit's MCP server is officially documented for four hosts today: Claude Desktop, ChatGPT, Gemini, and Cursor. Because MCP is an open standard, any other host that supports remote MCP servers (e.g. Continue, Zed, Aider) can also connect — the connect URL is mcp.hippokit.ai and authentication is a bearer-token PAT.

Does using MCP cost me anything extra?

No. MCP usage counts against the same daily generation quota as the HippoKit web app. Free is 3 generations / day, Plus is 25, Premium is 100. There is no separate "API" or "MCP" tier — connecting via MCP is included in every plan.

What tools does HippoKit expose over MCP?

Nine tools: generate_kit (the headline action), list_my_kits, get_kit, search_public_kits, claim_preview_kit, get_due_cards, review_card, start_quiz, and answer_quiz_question. Together they cover content generation, library access, and review sessions over flashcards and quizzes.

How do I revoke MCP access for one host without affecting the others?

Each PAT is independent. Issue one PAT per host (or per device), name them descriptively in the PAT manager at https://hippokit.ai/settings/mcp, and revoke individually any time. Revocation is immediate.

Is HippoKit's MCP server open source?

The MCP protocol implementation is open standard. The HippoKit server itself runs the same content-generation backend as the web app, so it's not separately open-sourceable. The wire format and tool list are documented; any compliant MCP client can connect.

Connect HippoKit to Claude, ChatGPT, Gemini, or Cursor (MCP)

HippoKit ships a remote Model Context Protocol (MCP) server at mcp.hippokit.ai. Connect it to Claude Desktop, ChatGPT, Gemini, or Cursor and your AI assistant can generate flashcards, quizzes, ebooks, audience-themed slide decks, and AI-narrated audio without leaving the conversation.

What is MCP?

Model Context Protocol is an open standard for letting an AI assistant call external tools. The assistant lives in a host — Claude Desktop, ChatGPT, Gemini, Cursor — and the tools live in a server somewhere else. The host opens a tunnel to the server, sees the tools it exposes, and calls them mid-conversation when the user asks for something the host can't do on its own. Think USB for AI assistants: one shared port, lots of devices.

HippoKit's MCP server lives at https://mcp.hippokit.ai/mcp and exposes tools to generate flashcards, quizzes, ebooks, slide decks, and AI-narrated audio lessons from any topic or PDF — flashcards in about a minute, themed slide decks in about five.Once you've connected, your AI assistant can take a topic out of your conversation, call HippoKit, and hand you back a shareable kit — all without you opening a browser tab.

Why connect HippoKit to your assistant?

Stay in the conversation. No tab-switching to hippokit.ai every time you want a study artifact. Ask in-chat, get a kit back, keep talking.
Use your assistant's context. The host has already seen your codebase (Cursor), your sources (NotebookLM-style uploads in ChatGPT / Claude), or your calendar (Gemini). Let it feed the relevant context into HippoKit's prompt instead of you re-typing it.
One quota, every surface. Generations via MCP count against the same monthly credit pool as the web app. Your library is identical whether the kit was made by you on hippokit.ai or by your assistant via MCP.

3-step quickstart

Works for every host. Picks up the host-specific settings path from the host cards below.

Generate a personal access token (PAT)
Open https://hippokit.ai/settings/mcp while signed in to HippoKit, click "Create token", and copy the value. The PAT inherits your plan's daily quota.
Add the MCP server to your host
Use the URL https://mcp.hippokit.ai/mcp and paste the PAT as the bearer token. Each host has a slightly different settings page — pick yours from the host cards below for the exact path.
Approve the connection and test it
Approve HippoKit's tool list in the host's permissions dialog, then ask: "Generate flashcards on photosynthesis using HippoKit". You should see a shareable kit URL in the response.

Pick your host

Each guide is a 2-minute walkthrough with the exact settings path, the connect-screen UX you'll see, and the troubleshooting tips that come up most often.

Claude Desktop

Generate kits inside your Claude Desktop conversation, then keep talking about them.

ChatGPT

Bring HippoKit into ChatGPT via OpenAI's new Connectors surface.

Gemini

Add HippoKit to Gemini via Google's Extensions surface and call kits from any Gemini conversation.

Cursor

Wire HippoKit into Cursor so your coding agent can also generate study kits on what it just built.

What HippoKit exposes over MCP

The MCP server exposes nine structured tools. Hosts call them with typed arguments; no free-form chat sneaks across the wire.

Tool	What it does
generate_kit	Generate a multi-format study kit on a topic. Honors plan quotas and format gating.
list_my_kits	List the kits in your library, optionally filtered by topic or audience.
get_kit	Fetch the full payload of one kit you own (flashcards + quiz + ebook + slide deck + audio).
search_public_kits	Search the public gallery of shared kits.
claim_preview_kit	Claim an anonymous preview kit into your account.
get_due_cards	Surface flashcards due for review today (FSRS-6 spaced repetition).
review_card	Record your recall rating on a flashcard and advance its review schedule.
start_quiz	Begin a quiz session over any of your kits.
answer_quiz_question	Submit an answer to the current quiz question and get scoring + explanation.
