它能帮你做什么

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。

安装

选择你使用的 AI 应用,然后复制设置。

安装之前

它能做什么

工具名称和描述与服务器在 2026年11月6日 报告的完全一致。这些内容由作者撰写,不是我们写的;我们以纯文本形式显示。

  • mcp_usage_metering

    Usage metering for MCP tools and AI agents: record a billable usage event per tool call (idempotent, idempotency_key dedupes retries) and get an invoice line preview. Per-call billing, usage-based pricing, metered billing for MCP servers. Every call requires one solved task: a ti

  • agent_spend_ledger

    Agent spend cap / budget ledger: set a budget, reserve before pay (atomic, never overspends even with many agents in parallel), then settle or release. Idempotent, shared by namespace. Spending limit, budget guard, cost control for AI agents. Every call requires a tiny solved pac

  • agent_lease_lock

    Distributed lock / lease lock (mutex) for AI agents: acquire, renew, release a named lock with TTL and a monotonic fencing token so only one agent runs a job at a time. Idempotent, shared by namespace, no Redis needed. Every call requires a tiny solved packet (returned in the rep

  • agent_semaphore

    Counting semaphore / concurrency limit for AI agents: at most N agents hold a slot at once (rate limit parallel workers), TTL permits with fencing tokens, auto-expire on crash. Idempotent, shared by namespace. Every call requires a tiny solved packet (returned in the reply, 2 s,

  • agent_heartbeat_registry

    Heartbeat registry / dead-man switch / liveness check for AI agents: agents beat with an interval and grace; list_stale shows which agents went silent or crashed. Idempotent, shared by namespace. Every call requires a tiny solved packet (returned in the reply, 2 s, one try); free

常见问题

Agent Billing Primitives (Dirtsmith) 安全吗?

它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。

它需要哪些密钥或代码?

注册中心没有列出必需的密钥,不过有些服务器会在首次使用时要求你登录。

它在我的电脑上运行还是在云端?

它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。

它还在维护吗?

GitHub 仓库最后更新于–,最新版本(1.4.0)于5天前进入注册中心。

哪些应用可以使用它?

支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

有什么可以替代它?

MCP Usage Metering + agent coordination (Dirtsmith)

Free first call, one step, no key, no signup: curl -s https://gap-functions.bfurrow26.workers.dev/try returns a tiny packet, the solve rule, and a one-liner. POST the answers back to /try and you get the real tool result. ?tool=agent_lease_lock (or any tool below) for the others.

Search words: usage metering, metered billing, idempotent, reserve before pay, spend cap, budget, distributed lock / lease lock, fencing token, semaphore, concurrency limit, heartbeat, dead-man switch, free first call.

Hosted tool that records one billable usage event per MCP tool call, idempotently, and returns an invoice preview. Built for MCP server authors who want to charge per call without building metering.

  • Endpoint (MCP): https://gap-functions.bfurrow26.workers.dev/mcp (all URLs in config.json)
  • Tool list: GET /mcp/tools · Health: GET /health
  • Contract: schema/mcp_usage_metering.v1.0.0.json (strict input, required idempotency_key, versioned 1.0.0)

Pricing and buying (no signup, no key)

  • Call the tool directly. Each IP gets 100 free keyless calls per day.
  • After that, tools/call returns isError: true with error_code: PAYMENT_REQUIRED. structuredContent.payment holds a one-click approve_and_pay_url for your human and a grant_token. Your agent asks you once, you click buy, then the agent retries the same call with header X-Grant-Token (or uses the /u/ /mcp URL form). Same token forever.
  • Usage after purchase: $0.15 per 1,000 events ($0.00015/event), 10,000 free events per month per account.
  • Replays with the same idempotency_key are never billed twice.

Inputs

Required: tool_name, tool_version (semver), end_customer_ref, idempotency_key (8–128 chars). Optional: units, unit_label, unit_price_cents, metadata.

More tools on the same endpoint (added 2026-11-03)

The same MCP URL (https://gap-functions.bfurrow26.workers.dev/mcp) also serves:

  • agent_spend_ledger: hosted shared budget ledger. Actions: set_budget, reserve, settle, release, status. Reserve is atomic: concurrent agents on one budget can never exceed the ceiling. Reservations expire after ttl_s (default 900 s). Amounts are integer micro-USD. $9.00 per 1,000 calls after 1,000 free calls a month.
  • agent_lease_lock: hosted lease lock. Actions: acquire, renew, release, status, with ttl_s and a monotonic fencing_token. $0.90 per 1,000 calls after 1,000 free calls a month.
  • agent_semaphore: hosted counting semaphore. Actions: acquire (with max_slots, holder_id, ttl_s), release (by permit_id), status. At most N permits at once; each permit carries a monotonic fencing_token; full returns NO_SLOT_FREE with retry_after_s. $0.90 per 1,000 calls after 1,000 free calls a month.
  • agent_heartbeat_registry: hosted dead-man switch. Actions: beat (with agent_id, interval_s, grace_s, optional note), status, list_stale (agents past interval + grace, up to 100). $0.90 per 1,000 calls after 1,000 free calls a month.

State is shared by namespace (16-128 chars). Any agent that knows the namespace can read and change that state, so treat it like a password. We store only its hash. Buying works the same way as metering: no signup or key, one approve-and-pay link when the free calls run out.
