Kill switch + spend guard for AI agents that spend money, across every wallet vendor at once.
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。
COUNTERSIGN_URL, COUNTERSIGN_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。

在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。
打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json
{
"mcpServers": {
"countersign": {
"command": "npx",
"args": [
"-y",
"@countersign/mcp"
],
"env": {
"COUNTERSIGN_URL": "your-value",
"COUNTERSIGN_API_KEY": "your-value"
}
}
}
}在终端中运行这条命令
claude mcp add countersign --env COUNTERSIGN_URL=your-value --env COUNTERSIGN_API_KEY=your-value -- npx -y @countersign/mcp运行前请先填写空着的值。

"env": {
"COUNTERSIGN_URL": "your-value",
"COUNTERSIGN_API_KEY": "your-value"
}
}
}
}浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

The cross-vendor kill switch + spend guard for AI agents — as MCP tools, inside any MCP client.
Countersign is a neutral control plane that holds one policy, one freeze, and one tamper-evident audit ledger across every agent-wallet backend at once. This package exposes it as Model Context Protocol tools, so an agent (or you, from chat in Claude / Cursor) can ask *"may I spend this?"* before acting — and freeze everything in under a second.
| Tool | What it does |
|---|---|
countersign_request_spend | Pre-flight guard — ask whether a spend is allowed *before* touching the wallet (allow / deny / needs_approval). |
countersign_freeze | The kill switch — freeze every agent on every backend at once. |
countersign_apply_policy | Apply one unified policy (caps, allow/deny lists, approval threshold) across all backends. |
countersign_list_agents / countersign_health | See the governed fleet + control-plane health. |
countersign_list_approvals / countersign_approve / countersign_deny | The human-approval queue. |
countersign_ledger | Read + re-verify the append-only, hash-chained audit ledger. |
countersign_unfreeze | Lift a freeze (recover). |
It governs a running Countersign Core. The hosted Core at app.countersign.network is paused since 2026-09-18 and answers 503, so point this at a Core you run yourself. Set:
COUNTERSIGN_URL — your Core, e.g. https://app.countersign.networkCOUNTERSIGN_API_KEY — required when the Core has auth enabledAdd to your MCP config (claude_desktop_config.json, or claude mcp add, or Cursor's mcp.json):
{
"mcpServers": { "countersign": { "command": "npx", "args": ["-y", "@countersign/mcp"], "env": { "COUNTERSIGN_URL": "https://app.countersign.network", "COUNTERSIGN_API_KEY": "csk_…" } } } }
That's it — your agent now has the spend guard and the kill switch.
If Countersign guards your agent, say so — it tells users (and other agents) that spending is governed, and points the next operator at the same kill switch. Drop this in your README:
