概览

AI 生成的概览

远程 MCP 端点，为 Hive A2A 网络按代理计量配额，每消耗一个配额单位以 Base 上的 USDC 结算。

可以做什么
  • 按代理 DID 查询并消耗配额单位，通过 x402 支付信封按单位付费
  • 读取某个 DID 的剩余配额余额
  • 估算指定单位数的报价与可接受的最低金额（USDC）
  • 通过 REST 端点提供同样的操作，包括 UTC 当日账本快照与健康检查
适用场景
适用于在 Hive A2A 网络上构建或运营代理、需要按代理做限流或配额核算并以 Base 上的 USDC 结算的场景。多数助手和通用用途并不需要它。
运行要求
远程 streamable-HTTP 端点，无需本地安装。消耗单位的调用需要一个有余额的 Base L2 钱包，能向公布的收款地址发送 USDC 并回传 X-Payment 证明头。服务器自身通过 RPC 地址读取 Base 主网。
安装前请注意
quota_check 会真实花钱：每个单位以 Base 主网 USDC 支付给运营方钱包地址，支付证明会在链上核验。公布的收款地址与价格属第三方声明，付款前请自行确认。该服务会在自己的数据库中保存按 DID 的使用记录。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Hive Agent Quota，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

hive-mcp-agent-quota

[srotzin/hive-mcp-agent-quota MCP server]

Per-agent quota meter for the A2A network. Each call to quota_check consumes one or more units against an agent's DID and is settled at $0.001 USDC per unit on Base L2 via the x402 envelope. Inbound only. ENABLE=true by default.

Brand color: #C08D23 (Pantone 1245 C, Hive Civilization gold).

Pricing and the barter floor

Pricing inherits the hivemorph barter pattern. Every 402 envelope advertises both amount_usd (asking) and accept_min_usd (floor). A client may submit a proof whose on-chain paid amount is anywhere in [floor, asking] and the shim accepts it.

Defaults, all overridable by environment variable:

VariableDefaultNotes
QUOTA_CHECK_PRICE_USDC0.001Per-unit asking price.
HIVE_X402_FLOOR_PCT_DEFAULT0.70Floor as fraction of asking.
HIVE_X402_FLOOR_MIN_PCT0.30Hard lower clamp.
HIVE_X402_FLOOR_MAX_PCT0.95Hard upper clamp.

So a 1-unit check at the defaults advertises asking $0.0010 and accept-min $0.0007. A 100-unit check advertises asking $0.1000 and accept-min $0.0700. The floor never falls below MIN_PCT of asking and never exceeds MAX_PCT.

Signature (optional)ethers.verifyMessage(message, signature) recovers payer; rejected if it disagrees with the on-chain from.

No mocks. The on-chain check is a real RPC read against Base mainnet.

Storage

SQLite at QUOTA_DB_PATH (default /tmp/quota.db), three tables:

  • quotas (did, units_purchased, units_consumed, first_seen, last_seen)
  • checks (id, did, unit_count, granted, remaining, tx_hash, paid_usdc, ts)
  • topups (id, did, units, paid_usdc, tx_hash UNIQUE, payer, ts)

tx_hash is UNIQUE on topups to make replay a 409.

x402 envelope

A quota_check call with no prepaid balance and no proof returns:

json
{  "error": "payment_required",  "x402_version": 1,  "payment": {    "nonce": "…",    "amount_usd": 0.001,    "accept_min_usd": 0.0007,    "accepts": [{      "chain": "base",      "asset": "USDC",      "contract": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",      "decimals": 6,      "recipient": "0x15184bf50b3d3f52b60434f8942b7d52f2eb436e",      "scheme": "exact"    }],    "expires_at": 1761600000,    "tier": 1,    "product": "agent_quota_check",    "unit_count": 1,    "price_per_unit_usd": 0.001,    "floor_pct": 0.70  }}

The client sends USDC to the recipient on Base, then resubmits the same request with an X-Payment header containing the proof:

X-Payment: {"nonce":"…","chain":"base","tx_hash":"0x…","payer":"0x…","signature":"0x…","message":"hive-quota:<nonce>"}

signature and message are optional. If supplied, the recovered address must match payer and the on-chain from.

Then:

Hard rules

  • Inbound only. The shim never originates an outbound payment.
  • No private key in the repo. Verification is read-only.
  • No custody. The recipient address belongs to the operator, not the shim.
  • Returns are advisory until the on-chain receipt is confirmed by BASE_RPC_URL.

Council provenance

Tier A position 3. 2026-04-27. Inbound metering surface, symmetric to hive-mcp-barter (outbound counter-offer) and hive-mcp-auction (inbound reverse-Dutch).
