Common questions

Is Flipzi MCP safe?

It passed 1 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?

You need to fill in: FLIPZI_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 23 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Flipzi MCP server

Ask Claude, Cursor or any MCP client about trading card prices: search cards, get current prices, sold comps, price history, market movers, games and sets. It is a thin local wrapper over the Flipzi Data API. You bring your own Flipzi API key; the free plan needs no card.

Runs on your machine over stdio (npx). Nothing is hosted, and the only network traffic is your requests to data.flipzi.io.

Source: https://github.com/flipzitcg/flipzi-mcp. Public mirror; please report problems as GitHub issues rather than pull requests.

1. Get a key (free)

Create an account: https://flipzi.io/account/register?product=data&utm_source=npm&utm_medium=directory&utm_campaign=202610_mcp
Verify your email. A free key allowance (500 units/month, 5 requests/minute) is created for you.
Create a key at https://flipzi.io/account/keys (it starts with fz_live_ and is shown once).

2. Add it to your AI tool

Requires Node.js 18+. Replace fz_live_... with your key.

Claude Code

claude mcp add --env FLIPZI_API_KEY=fz_live_... --transport stdio flipzi -- npx -y @flipzitcg/mcp

Check with claude mcp list or /mcp. Add --scope user to use it in every project.

Claude Desktop (one click) — once the release publishes it, download flipzi-mcp.mcpb from the GitHub releases and open it; Claude Desktop asks for your key in a masked field.

Claude Desktop (config file) — Settings → Developer → Edit Config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows), then fully quit and reopen the app:

"mcpServers": { "flipzi": { "command": "npx", "args": ["-y", "@flipzitcg/mcp"], "env": { "FLIPZI_API_KEY": "fz_live_..." } } } }

Cursor — add the same block to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project). Do not commit a file containing your key.

Then ask: *"What's an Umbreon VMAX worth right now?"* or call flipzi_account to see your plan.

Tools

Tool	Needs	Units	What it does
`flipzi_account`	any key	0	Your plan, allowance used, which tools your plan unlocks
`flipzi_list_games`	Free	1	Supported games
`flipzi_list_sets`	Free	1	Sets of a game
`flipzi_list_set_cards`	Free	1	Cards in a set (gets card ids)
`flipzi_search_cards`	Free	1	Search by name
`flipzi_get_card`	Free	1	Card details
`flipzi_get_price`	Free	1	Current price, market and confidence (graded needs Pro)
`flipzi_get_history`	Basic	1	Daily history (30 days on Basic, longer on Pro+)
`flipzi_get_sold_comps`	Pro	1	What buyers actually paid on eBay
`flipzi_get_movers`	Ultra	5	Biggest gainers/losers for a game
`flipzi_get_box_value`	Pro	1	Sealed booster-box price vs the estimated value of the cards inside (English Pokémon boxes that pass checks; a range, not a promise)
`flipzi_get_cardmarket_conditions`	Ultra	1	Cardmarket asking prices per language, finish and Cardmarket grade (Mint to Poor): cheapest and median, with the date read

Requirements are read from the API's own contract (openapi.yaml, version in src/plans.generated.ts), not guessed. Plans and prices: https://flipzi.io/api/pricing/?utm_source=npm&utm_medium=directory&utm_campaign=202610_mcp. Every tool is always listed. When your plan does not include one, the tool says so, names the plan that does, links the upgrade, and the refusal costs 0 units.

Allowance and limits

One unit per call (movers 5). The API counts per account per UTC month; flipzi_account shows what is left.
The free plan allows 5 requests per minute. A short wait (≤10 s) is retried once automatically; longer waits are reported.
Session budget: this server stops itself after FLIPZI_MCP_MAX_UNITS units per run (default 150) so an agent loop cannot burn your month. Set 0 for unlimited. Restart the server to reset it.
Output is capped at about 20 KB per call; search returns 10 cards by default.

Settings (environment variables)

Variable	Default
`FLIPZI_API_KEY`	required	Your key. Never printed or logged.
`FLIPZI_MCP_MAX_UNITS`	`150`	Per-run unit budget, `0` = unlimited
`FLIPZI_MCP_NO_CLIENT_TAG`	unset	`1` stops sending the client header below
`FLIPZI_API_BASE`	`https://data.flipzi.io`	For testing only

What is sent, and what Flipzi learns (no hidden telemetry)

Your requests go to data.flipzi.io with your key, exactly as any API client would. There is no other network call, no analytics service, no update check, and no remote control.
Each request carries User-Agent: flipzi-mcp/ and X-Flipzi-Client: mcp/ . Flipzi records only that the call came from the MCP server (the value mcp), so it can count MCP usage and see which plan-locked tools people try. Opt out with FLIPZI_MCP_NO_CLIENT_TAG=1; everything works the same.
Links this server prints (signup, keys, upgrade) include utm_source=mcp so Flipzi can tell that an account started from here. They are plain query parameters you can delete.
Prompts, conversations and card queries are not sent anywhere except as the API parameters of the call you asked for.

Troubleshooting

*"FLIPZI_API_KEY is not set"* — the key is missing from the env of your client config; restart the client after editing.
*Tools don't appear in Claude Desktop* — fully quit and reopen; check ~/Library/Logs/Claude/mcp-server-flipzi.log (macOS) or %APPDATA%\Claude\logs (Windows). On Windows, if npx fails, install npm globally (npm install -g npm).
*"Not on your plan"* — expected; see the table. Run flipzi_account.
Quote the request_id in any error when contacting support. See SUPPORT.md.

The free plan carries no commercial-use grant. Data is for informational use; see the API terms. MIT licensed.
