Nobrainner missed 3 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Available tools 38

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

deck

create_deck_draft

Call get_student_overview and get_usage_limits first. The schema accepts up to 200 cards so Pro can create large drafts. Free: up to 50 cards per draft, 3 drafts/day and 30/month. Pro: up to 200 cards per draft, 10 drafts/day and 150/month. Never send more than the current plan allows; split oversized drafts only when remaining draft quota allows it. Drafts are inactive until save_deck_draft is explicitly confirmed. Ask before adding audio: Free users receive standard Neural2; Pro users can choose the more natural-sounding premium-female or premium-male Chirp3-HD voice. Ask Pro users which voice they prefer. Saving consumes one cloud deck job plus requested TTS/audio quotas.

get_deck_detail

Returns one deck and a paginated page of its current cards. Card IDs are stable identifiers for search, edits, and deletion.

get_deck_folders

Returns the student dashboard style plus every folder and deck aesthetic setting and the supported values for safe personalization.

get_deck_list

Returns the authenticated student deck list with status, card counts, source, settings, and sync metadata.

get_deck_settings

Returns study settings for a deck.

search_deck_cards

Searches the signed-in student’s current deck card text using a case-insensitive substring match across front and back. Results are paginated and include stable card IDs; the scan covers all deck shards but returns only the requested page.

update_deck_settings

Updates settings after explicit user confirmation.

folder

create_folder

Creates a deck organization folder.

delete_folder

Deletes a folder and moves its decks to the root.

update_folder

Renames or updates an existing folder.

shared

get_shared_catalog

Browses the public NoBrainner community deck catalog.

get_shared_deck_management

Returns owned decks, catalog visibility, classification, publication state, and share links.

update_shared_deck_management

Changes an owned deck catalog classification or public/private visibility. Publishing or unpublishing requires explicit confirmation and never changes imported shared decks.

accessibility

get_accessibility_settings

Returns UI scale, reduced-animation, and review audio-speed visibility settings.

update_accessibility_settings

Updates account-wide UI scale, reduced animations, or review audio-speed visibility after the student requests it.

card

delete_card

Removes the card content for one exact card ID after explicit confirmation; historical review logs and aggregate study totals remain. In an imported community deck, deletion affects only the student’s personal copy. At least one card must remain. Supports NoBrainner-created decks and imported community decks; multi-shard Anki imports are read-only in ChatGPT.

update_card

Updates the front and/or back text for one card ID after explicit confirmation. Keeps its stable card ID and FSRS progress; updates to an imported community deck affect only the student’s personal copy. Supports NoBrainner-created decks and imported community decks; multi-shard Anki imports are read-only in ChatGPT. If deck audio is enabled, editing text can regenerate audio and consume quota.

flashcard

get_flashcard_appearance

Returns the current flashcard theme and supported color options from Edit Profile.

update_flashcard_appearance

Changes the authenticated student flashcard theme or color. Only call when the student requests this change; imported Anki templates are not restyled.

profile

get_profile_settings

Returns profile basics and accessibility settings from Edit Profile.

update_profile_basics

Updates the student display name, flag, or built-in avatar. Custom photo uploads remain in Edit Profile.

app

get_app_capabilities

Explains NoBrainner features, Chrome extension, Video Practice, ranking, and documentation links.

bulk

bulk_update_cards

Updates 1–20 card IDs in one deck after explicit confirmation. Each edit preserves that card’s ID and FSRS progress. This is not atomic: if a later edit fails, the result reports cards already updated and the failed card. Check usage limits and tell the user first if deck audio may regenerate and consume quota.

cards

add_cards_to_deck

Adds 1–50 structured front/back cards after explicit confirmation. In an imported community deck, additions belong only to the student’s personal copy. Supports NoBrainner-created decks and imported community decks; multi-shard Anki imports are read-only in ChatGPT. Check usage limits and tell the user first if the deck’s audio policy may generate speech and consume audio quota.

customize

customize_deck

Customizes a deck title, emoji, color, border, font, font weight, or order. Use get_deck_folders first for the supported values.

dashboard

update_dashboard_appearance

Sets the authenticated student dashboard to Playful or Subtle. Only call when the student requests this change.

friends

get_friends_leaderboard

Returns the authenticated student’s Friends league, weekly XP ranks, and current position.

import

import_shared_deck

Imports a public community deck into the student account.

leaderboards

get_leaderboards

Returns weekly NoBrainner global leaderboard rankings, streak leaders, and the authenticated user position.

move

move_deck_to_folder

Moves a deck into a folder or back to the root.

preview

preview_deck_draft

Previews a pending deck draft before it is saved.

review

get_review_timeline

Returns daily NoBrainner study activity for the last N days.

save

save_deck_draft

Call get_usage_limits first. Saves a confirmed draft as a ready deck and consumes one cloud deck job plus requested TTS/audio quotas. Pro drafts can use premium-female or premium-male Chirp3-HD; Free drafts are enforced as standard Neural2. Only call after explicit confirmation.

streak

get_streak_details

Returns read-only streak, freeze, recovery, and recent daily activity history without changing study progress.

student

get_student_overview

Returns the authenticated student overview: profile basics, current Free/Pro plan, available voice options, progress, decks, recent grades, and weak-deck signals. Free includes standard Neural2 audio; Pro includes more natural-sounding Chirp3-HD female and male voices. Call get_usage_limits before any deck creation or other metered operation.

usage

get_usage_limits

Returns the authenticated student plan, daily/monthly usage, remaining allowances, deck limits, and audio allowances. Always call this before creating or saving a deck. Free includes standard Neural2 audio; Pro can choose more natural-sounding Chirp3-HD female or male voices. The create tool schema accepts up to 200 cards, but backend policy is Free 50 cards and Pro 200 cards per draft.

user

get_user_stats

Returns detailed NoBrainner student learning statistics: accuracy rate, grade distribution, active/total deck counts, streaks, total reviews, estimated study hours, and 30-day accuracy history.

weak

get_weak_cards

Returns cards with the strongest recent Again/Hard signal.

Nobrainner — questions

Answers built from our own checks of this server.

What can Nobrainner do?

It exposes 38 tools, read directly from the server on our last check. Among them: add_cards_to_deck, bulk_update_cards, create_deck_draft, create_folder, customize_deck, delete_card and 32 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Nobrainner mostly used for?

Its tools cluster around deck, folder and shared. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Nobrainner working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 609 ms. The bar chart above shows every period we have measured.

Is Nobrainner still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Nobrainner?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to Nobrainner?

No API key is involved. Nobrainner answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is Nobrainner?

It answers our handshake in 609 ms on average, which is faster than 19% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
