Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
作者提供的说明(英文原文)
Verifiable entropy, provably-fair games, and receipt verification for AI agents (FairSeal API).
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。
FAIRSEAL_API_KEY, FAIRSEAL_API_URL, FAIRSEAL_NOTARY_API_KEY, FAIRSEAL_ANCHOR_API_KEY标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。

打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json
{
"mcpServers": {
"fairseal": {
"command": "npx",

"-y",
"@fairseal/mcp-server"

"FAIRSEAL_API_KEY": "your-value",
"FAIRSEAL_API_URL": "your-value",
"FAIRSEAL_NOTARY_API_KEY": "your-value",
"FAIRSEAL_ANCHOR_API_KEY": "your-value"
}
}
}
}在终端中运行这条命令
claude mcp add fairseal --env FAIRSEAL_API_KEY=your-value --env FAIRSEAL_API_URL=your-value --env FAIRSEAL_NOTARY_API_KEY=your-value --env FAIRSEAL_ANCHOR_API_KEY=your-value -- npx -y @fairseal/mcp-server运行前请先填写空着的值。

Provably fair selections for games, loot boxes, and any randomized allocation.
Fairseal creates verifiable receipts (CSRs) proving that a selection was committed before the outcome was knowable. Every loot drop, gacha pull, and randomized selection — independently verifiable, trustlessly.
npx @fairseal/commit
One command. A verifiable gacha pull in your terminal. No setup.
npm install @fairseal/commit
import { createCommitment, resolveCommitment, createReceipt, verifyReceipt } from '@fairseal/commit';
// 1. Lock your loot table BEFORE the outcome is knowable const commitment = createCommitment({ rule: JSON.stringify(LOOT_TABLE), inputs: [playerId, pullNumber.toString()], revealAfter: 10, });
// 2. Resolve with verifiable entropy from drand const resolution = await resolveCommitment(commitment);
// 3. Your algorithm + verifiable entropy = provably fair drop const drop = yourWeightedPull(LOOT_TABLE, resolution.beaconRandomness);
// 4. Package as a receipt anyone can verify const receipt = createReceipt(commitment, resolution); const proof = await verifyReceipt(receipt); // ✅ PARTIAL
| Operation | Time |
|---|---|
| Commitment creation | 0.006ms (170,000+/sec) |
| Beacon fetch | ~200ms |
| drand beacon verification (BLS12-381) | ~150ms |
| Receipt size | 0.9 KB |
Client-side. No server. No account. No fees for PARTIAL verification.
| Package | Description |
|---|---|
@fairseal/game | Game API for RGS studios. Slots, gacha, loot boxes. (v0.1 ALPHA) |
@fairseal/commit | Committed selection receipts. Core library. |
@fairseal/core | Cryptographic primitives, signing, Merkle trees. |
@fairseal/verify | Independent receipt verification. |
@fairseal/mcp-server | MCP server for AI agents. Verifiable entropy, provably-fair games, cryptographic receipt verification via Model Context Protocol. |
| Scenario | How |
|---|---|
| Gacha / loot box | Every pull has a receipt. Players verify drops match published rates. |
| Boss loot drops | Drop table committed per encounter. No ninja-nerfing. |
| Matchmaking | Pairing algorithm committed. Players verify no favoritism. |
| Tournament brackets | Seeding provably random, not rigged. |
| NFT mint order | Queue provably fair — no insider front-running. |
| Slot machines | Seed Commitment Model — verifiable spins, no nonce chain. |
Most "agent receipts" today are activity receipts: the platform logs what an agent did, and you trust whoever wrote the log. Fairseal receipts are result notarization — a different trust model:
| Activity receipts (platform logs) | Fairseal result notarization | |
|---|---|---|
| Who do you trust? | The operator writing the log | No one — receipts verify offline |
| What is proven? | That an action was recorded | That a result was committed before the outcome was knowable |
| Time proof | Server timestamp (operator-controlled) | External anchor on Base (independently checkable) |
| Tamper evidence | Depends on log integrity | Hash-anchored; any modification breaks verification |
Related standards: payment-authorization protocols like Google/Mastercard AP2 (mandates), Visa TAP, and OpenAI/Stripe ACP prove that an agent *may* act and *who* it is. Fairseal proves *what happened* — that a result was committed and hasn't been altered since. Fairseal settles micropayments over Coinbase's x402 and does not implement AP2/TAP/ACP; the layers are complementary.
