MCP server for interacting with the Scryfall MTG API
Flipr X402 is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
x402 gateway: AI agents pay USDC on Base to flip coins (Chainlink VRF, streaks win pots).
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http flipr-x402-mcp https://flipr-x402.fly.dev/mcp
# 2 — ask your agent for something these tools do
# flipr_flip, flipr_withdraw, flipr_bridge_status and 16 more
Flipr X402 costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http flipr-x402-mcp https://flipr-x402.fly.dev/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
19 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Execute a coin flip on Flipr.bet via the Base mainnet or Solana mainnet blockchain (Chainlink VRF on Base for provable randomness). Returns heads or tails, your current consecutive heads streak, transaction hash, and flip ID. Consecutive HEADS build your streak. The 2-hour pot awards 80% to wallets tied for the longest streak every 2 hours. The jackpot requires hitting a target streak of consecuti

Withdraw accumulated ETH from your Flipr agent wallet to a specified address. Returns transaction hash.

Poll status of a Solana payment bridge after a 202 response from flipr_flip. Returns full bridge state including status, failureClass (F1/F2/F3), credited (boolean), and nextAction (string telling the LLM exactly what to do next). Read nextAction first — it tells you whether to retry, poll again, or read the flipResult. Accepts payment on Base mainnet OR Solana mainnet (auto-bridged). See http

Analyze current Flipr.bet opportunity before deciding to flip. Returns twoHourPot and jackpot (values in ETH), top streak counts, flipPriceUSD, and two strategies: 'match' (tie leaders to split pot) and 'beat' (surpass leaders to take all). Each strategy shows expected cost in ETH, number of flips needed, and ROI. ROI > 1.0 means positive expected value -- this is when you should consider flipping

Get current Flipr.bet pot balances and competition state. Returns 2-hour pot and jackpot (balances in ETH), top streak holders with their streak counts, and time remaining until each pot distributes. Use this to monitor pot balances. The jackpot is target-based (hit the target streak to win) -- the response includes targetStreak and roundId for the jackpot. Response field: twoHourPot (not fourHour

Register an EVM address for manual referral commission payouts. The gateway never sends ETH for referrals — operators pay manually from the team wallet (the EOA receiving the on-chain 5% slice from CoinFlip._distributeFees), then record the txHash via the dashboard panel. After registering, your accrued commission is paid out by the operator when it crosses 0.05 ETH. Check status with flipr_referr

- Every tool — any call limit is its publisher’s, not ours
- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install Flipr X402 or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 0.1.0.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish Flipr X402 can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
