常见问题

Agentguard 安全吗?

它在 1 项适用的基础检查中通过了 1 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(1.0.0)于6个月前进入注册中心。

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?

同一分类中有:Spec Driven Development, Remote Desktop Commander, HotCodePush

🛡️ AgentGuard MCP

Security, Policy & Audit Layer for AI Agent Tool Execution — 20 tools | Part of FeedOracle & ToolOracle

AgentGuard is the governance and security layer for AI agent workflows. Before any tool executes, AgentGuard evaluates policies, scores risk, detects secrets and injection attempts, logs to a tamper-evident audit trail, and explains every decision. Built for regulated environments, autonomous payments, and enterprise AI agent deployments.

How It Works — The Agent Security Loop

Agent wants to call: payment_execute({amount: 5000})

│ ▼ policy_preflight() ← Check before execution │ risk_score: 95 ← Critical matched: pol-001, pol-002 ← Payment + High-risk policies decision: require_approval ← Human gate triggered │ approval_required() ← Register pending approval │ [Human approves] │ tool executes │ audit_log_write() ← Record outcome with signature │ decision_explain() ← Exportable compliance evidence

Tools — Welle 1: Core Security (7)

ToolDescription
policy_preflightPre-flight check before any tool call. Evaluates 7 policies, computes risk score, detects threats, auto-logs. Returns allowed/denied/require_approval/flagged.
tool_risk_score0-100 risk score for tool + input. Detects secrets (API keys, passwords), prompt injection, high-value amounts. eth_gas→5, payment_execute→95+.
approval_requiredCheck if tool needs human approval. Optionally registers a pending approval request with tracking URL.
audit_log_writeWrite tool execution to persistent, cryptographically-signed audit log (SQLite WAL). Call after execution to record outcome.
audit_log_queryQuery audit trail. Filter by agent, tool, decision, time range. Paginated. Returns signed entries for tamper verification.
decision_explainHuman-readable explanation of any allow/deny decision. Pass request_id for stored entry or tool_name + tool_args for fresh analysis.
rate_limit_checkCheck agent rate limits: 200/min, 5000/hr, 50000/day. Returns per-window usage with percentage.

Tools — Welle 2: Payment Controls & Safety

ToolDescription
payment_policy_checkValidate payment against policy: amount limits (>100k warns, >1M blocks), recipient denylist, supported currencies/networks, AML thresholds (>10k fiat flagged), MiCA flags.
spend_limit_checkCheck per-call/hour/day spend limits by trust level. Default: 10k/call, 50k/hr, 200k/day. Trusted: 100k/call, 500k/hr, 2M/day.
secret_exposure_checkDeep scan for 19 secret patterns: OpenAI/GitHub/AWS/Slack keys, Bearer/Basic auth, ETH private keys, Bitcoin WIF, credit cards, SSNs, emails. Returns severity + remediation.
payload_safety_check18-pattern safety scan: prompt injection, jailbreak/DAN, role hijacking, SQL (UNION/DROP/OR 1=1), XSS, Python/JS/Shell injection, path traversal, null bytes, oversized payloads.
replay_guard_checkDetect replay attacks via SHA256 fingerprint (agent+tool+args). Configurable window (default 5 min). Returns duplicate count + first/last seen.

Tools — Welle 3: Governance & Threat Intelligence (5)

ToolDescription
cross_tool_anomaly_checkDetect anomalous patterns: risky combos (wallet-recon→transfer, AML→payment), high frequency, repeated denials (policy probing), broad reconnaissance, elevated avg risk score.
scope_checkRole-based scope control. Roles: admin, compliance_officer, trader, auditor, developer, readonly. Returns has_scope, missing scope, granting roles. Logs denials.
session_validateFull session lifecycle: create (TTL + call budget), validate (increment counter), invalidate, info. Sessions carry role, scopes, tenant, expiry.
tenant_policy_checkMulti-tenant governance. Built-in tenants: default, fintech_eu (MiCA/DORA/AMLD6), defi_protocol, enterprise_read. Per-tenant blocklists, risk limits, spend caps.
threat_intel_checkEntity threat intelligence. Auto-detects ETH addresses, IPs, domains. Checks sanctions (Tornado Cash, mixers), disposable services, behavioral analysis from audit log.

Use Cases

  • Regulated AI Workflows: MiCA/DORA compliance requires audit trails — AgentGuard provides them automatically
  • Autonomous Payments: x402 agent payments run through approval_required gate before execution
  • Multi-tenant Platforms: Rate limiting and policy scoping per agent/session
  • Security Monitoring: Real-time detection of prompt injection and secret exposure in tool arguments
  • Compliance Reporting: Export audit log with cryptographic signatures for regulatory review

Backend: SQLite WAL-Mode

Persistent, stable, no daemon required. WAL-mode supports 1000+ writes/second. Shared between feedoracle.io and tooloracle.io — one source of truth.
