Ship with your collection data.
A REST API and an MCP server for Pokémon card search and your own binders. Everything you need to connect lives in the docs at /app/docs.
Open /app/docs
Start at /app/docs. Humans and AI tools alike.
The docs cover authentication, endpoints, scopes and MCP setup. AI coding assistants and agents can start there too: point your tool at /app/docs and it has what it needs to connect to Holo Folder.
What you can build.
Import pipelines.
Write entries into a named binder from your own scripts. Match exact printings by set, number, language and finish, and review conflicts before writes land.

What it saves you
Clean card data
Distinct IDs for printings, physical copies, slots and collections. Pokémon catalog results identify their game.
Straightforward imports
Write into named binders and review conflicts before they land.
Honest values
Unknown prices come back as unknown, never as a guess.
Connect in three steps.
01
Read /app/docs
Authentication, scopes, endpoints and MCP setup are documented in one place. AI tools can read it to get started too.
02
Pick your transport
Use a personal API key for REST, or connect a compatible MCP client and approve it through OAuth.
03
Start read-only, then write
Keys and connections are read-only by default. Enable write permissions only when your integration needs them.
Good to know
Where do I find connection details?
At /app/docs. It covers REST authentication, available endpoints and how to add Holo Folder to an MCP client.
Can my AI tool set itself up?
Yes. Point an AI assistant or agent at /app/docs and it can follow the setup steps. You still approve its access through OAuth.
What access do I need?
Premium or lifetime access. Private collection data always requires your authorization, and you can revoke keys any time.
Is there a guide for a first integration?
Yes. Read Getting started with the Holo Folder API on the blog, then use /app/docs as the full reference.
Can I import from a spreadsheet?
Yes. Map rows to exact printings and import into a named binder with a write-enabled key. The blog has a step-by-step guide.
