Common questions

Is ThinkSpace safe?

It passed 0 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 (0.2.1) reached the registry 8 days 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?

thinkspace-mcp

An MCP server that sends notes from your AI conversations to the ThinkSpace inbox — so what you reach with AI doesn't scroll away in a chat log, and ends up as cards you arrange with your own hands.

ThinkSpace's philosophy: AI helps gather and diverge; you build the map, because only what you build yourself stays in your head. Accordingly, this server never creates cards directly — it only delivers material to the inbox. Turning material into cards is yours.

Remote server (recommended): https://mcp.thinkspace-app.com/mcp — works from claude.ai, ChatGPT, Claude Code, and any MCP client that supports OAuth. Notes arrive on every device where you're signed in to ThinkSpace.
Local server (legacy): a stdio bridge for Claude Code on the same Mac as the app.

Remote server

Connect

Client	How
claude.ai (web / desktop / mobile)	Settings → Connectors → Add custom connector → URL `https://mcp.thinkspace-app.com/mcp`
ChatGPT	Settings → Connectors (developer mode) → Create → MCP server URL `https://mcp.thinkspace-app.com/mcp`, auth OAuth
Claude Code	`claude mcp add --transport http thinkspace https://mcp.thinkspace-app.com/mcp` then `/mcp` to sign in

The client opens ThinkSpace's connection page. Sign in with your ThinkSpace email and password, or — if you use Sign in with Apple — with a 6-digit code from the app: Inbox → link icon (top right) → “Get a connection code” (valid for 10 minutes).

You can see and revoke connections in the same screen in the app. A revoked connection gets a 401 on its next call and the client asks you to connect again.

Use

「いまの結論、受信箱に送って」

"Send this to my ThinkSpace inbox."

The client calls send_to_inbox with the full text of the message and a rough label. Open the inbox in ThinkSpace (iPhone / iPad / Mac) and decide what becomes a card.

Tool

`send_to_inbox`

input	description
`text` (required)	Note body — the verbatim full text of one chat message
`title` (optional)	Label draft, ideally ≤20 characters (you'll rewrite it by hand)
`source` (optional)	Origin identifier, defaults to `mcp`

Annotations: readOnlyHint: false, destructiveHint: false, idempotentHint: false. The server only writes to the inbox; it cannot read your inbox or canvases.

Limits: 60 notes per minute per user; bodies over 30,000 characters are cut at that point and flagged as truncated.

How it works

One Cloudflare Worker serves both the OAuth 2.1 authorization server and the MCP endpoint (Streamable HTTP, stateless). Discovery via RFC 9728 / RFC 8414, dynamic client registration (RFC 7591) and client ID metadata documents, PKCE S256, refresh-token rotation.
The authorization page is ThinkSpace's own. Passwords are verified against ThinkSpace's auth service and never stored or logged. App codes are one-time and expire in 10 minutes.
Each connection is recorded and can be revoked from the app. Tokens carry only the user id and connection id.
Notes are written to the ThinkSpace backend (Supabase) as inbox items and delivered to the app by its normal sync.

Develop

cd remote

npm install cp .dev.vars.example .dev.vars # SUPABASE_URL / SUPABASE_ANON_KEY / SUPABASE_SERVICE_ROLE_KEY npx wrangler dev # http://localhost:8787/mcp ./node_modules/.bin/tsc --noEmit npx wrangler deploy

Secrets in production are set with wrangler secret put (see remote/wrangler.jsonc). The service role key lives only in Worker secrets and .dev.vars (gitignored).

Local server (legacy, macOS only)

A stdio server that hands notes to the ThinkSpace app on the same Mac via the thinkspace:// URL scheme; the app's own sync then delivers them to your iPad / iPhone. No account or token is needed, but it only works with Claude Code on that Mac.

claude mcp add thinkspace -- npx -y thinkspace-mcp

or from a local checkout

git clone https://github.com/naoyax628X/thinkspace-mcp.git cd thinkspace-mcp && npm install claude mcp add thinkspace -- node /path/to/thinkspace-mcp/index.js

The npm package is thinkspace-mcp, published by the same author as this repository; it contains only index.js (the local bridge).

Requires Node.js 18+ and the ThinkSpace Mac app. The tool is the same send_to_inbox; source defaults to claude-code, and bodies beyond URL-scheme limits are delivered via the clipboard channel (source becomes clipboard). Note that the clipboard channel overwrites whatever is on your clipboard at that moment.
