Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00225 |
| Opus 5 | $0.00000 | $0.00112 |
| Sonnet 5 | $0.00000 | $0.00045 |
| Haiku 4.5 | $0.00000 | $0.00022 |
Grade A, and why
mcpguard-gov scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MCPGuard-Gov
用途
基于类型化身份与任务上下文、RBAC/ABAC、签名能力票据、数据标签传播、事务化审批和安全的 MCP 模拟服务，对智能体工具请求进行授权。高风险请求必须阻断或暂停并进入人工复核。
公共接口
from mcp.gateway import (
check_tool_call,
guarded_tool_call,
issue_tool_capability,
resume_approved_tool_call,
)
check_tool_call 只执行策略裁决。除非请求已暂停等待审批，否则通过 guarded_tool_call 执行时必须提供与任务绑定的能力票据。审批通过的任务使用 resume_approved_tool_call 恢复，并且只能消费一次。
安全边界
原型中的 Shell、删除、外部 API、数据库写入、浏览器和邮件操作不得执行真实危险动作。任何外部副作用都必须继续经过能力票据、策略检查、必要审批和审计记录。
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mcpguard-gov is a skill published in the GitHub repository YouYou-lj/GovSafeAgent (2 stars, last pushed 2d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 225 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
