MCP server for interacting with the Scryfall MTG API
Nothing to run from here
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.

Installation
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.
Claude Codedeclared by this listing
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.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
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.

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.

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.

No rule-by-rule report on file for this release
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.

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.
