Pin ideas from your
AI agents.

GeckoPin is a visual board that works with Claude, ChatGPT, Codex, and anything that speaks MCP. AI agents pin notes, links, and more to your board — your data never leaves your browser.

Claude just pinned 3 things

while you were away

Works with any
MCP client.

Pair your editor to a browser-owned board. Your data stays local, and remote MCP access works only while that GeckoPin tab is connected.

Open GeckoPin in your browser

Use Board menu -> Pair editor to copy the stable MCP config for the current board. If you need the current relay session headers instead, use Board menu -> Copy AI attach config.

Add the paired config

Paste the stable GeckoPin MCP server config into Claude, ChatGPT, Codex, or any MCP-compatible client.

{
"mcpServers": {
  "geckopin": {
   "type": "http",
   "url": "http://127.0.0.1:3845/mcp",
   "headers": {
    "Authorization": "Bearer <paired-installation-token>"
   }
  }}
}}

The paired-editor config stays stable across relay restarts and normal relay-session renewal for the same board.

Keep the board tab connected

GeckoPin resolves the live app session for that board on the server side, so you do not need to refresh MCP headers during normal use. If you choose Board menu -> Unpair editor, the installation token is revoked and the editor must be paired again.

Need AI attach headers?

Copy AI attach config includes the current bearer token plus relay session header. MCP clients using that flow must send both headers.

Good questions.

Here are a few we get a lot.

What is MCP?

MCP (Model Context Protocol) is an open standard that lets AI assistants connect to external tools. GeckoPin provides a hosted MCP relay so agents like Claude can read and write pins on your board in real-time.

Does the server store my board data?

No. Your board lives entirely in your browser. The hosted relay routes requests between your AI agent and your browser tab but stores zero board content at rest — only session metadata and auth tokens.

How does agent access work?

Use Board menu -> Pair editor to create a stable installation token for the current board. GeckoPin resolves the live app session for that board on the server side, so your MCP client can keep using the same config across relay restarts and normal session renewal. If you unpair the editor or close the owning GeckoPin tab, remote MCP access stops until you pair again or reconnect the board.

Which AI assistants are supported?

GeckoPin works with Claude, ChatGPT, Codex, and any MCP-compatible client. If your AI speaks MCP, it can pin to your board.

Can I use GeckoPin without an AI?

Absolutely. GeckoPin is a fully functional visual board on its own. Add, move, and organize pins manually — then optionally connect an AI agent when you're ready.

What happens if I lose connectivity?

You keep editing normally — everything is local. The app silently reconnects to the relay in the background when connectivity returns, and agent access resumes automatically.

Can I move the data to another device?

Yes. Your board data is stored locally in your browser. You can export your board and import it on another device to continue working seamlessly.

Is GeckoPin free?

Yes, completely free. No plans, no subscriptions, no paywalls. Just open it and go.
