Common questions

Is Agentguard safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

🛡️ 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)

Tool	Description
`policy_preflight`	Pre-flight check before any tool call. Evaluates 7 policies, computes risk score, detects threats, auto-logs. Returns `allowed`/`denied`/`require_approval`/`flagged`.
`tool_risk_score`	0-100 risk score for tool + input. Detects secrets (API keys, passwords), prompt injection, high-value amounts. `eth_gas`→5, `payment_execute`→95+.
`approval_required`	Check if tool needs human approval. Optionally registers a pending approval request with tracking URL.
`audit_log_write`	Write tool execution to persistent, cryptographically-signed audit log (SQLite WAL). Call after execution to record outcome.
`audit_log_query`	Query audit trail. Filter by agent, tool, decision, time range. Paginated. Returns signed entries for tamper verification.
`decision_explain`	Human-readable explanation of any allow/deny decision. Pass `request_id` for stored entry or `tool_name` + `tool_args` for fresh analysis.
`rate_limit_check`	Check agent rate limits: 200/min, 5000/hr, 50000/day. Returns per-window usage with percentage.

Tools — Welle 2: Payment Controls & Safety

Tool	Description
`payment_policy_check`	Validate payment against policy: amount limits (>100k warns, >1M blocks), recipient denylist, supported currencies/networks, AML thresholds (>10k fiat flagged), MiCA flags.
`spend_limit_check`	Check 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_check`	Deep 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_check`	18-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_check`	Detect 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)

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

Built-in Tenants

Tenant	Max Risk	Spend/Day	Frameworks
`default`	70	100,000	—
`fintech_eu`	60	500,000	MiCA, DORA, AMLD6
`defi_protocol`	80	10,000,000	MiCA
`enterprise_read`	30	0	—

Built-in Roles & Scopes

Role	Scopes
`admin`	All scopes

Built-in Policies (7 Default)

Policy	Condition	Action
pol-001	Payment/transfer tools	`require_approval`
pol-002	Risk score ≥ 80	`require_approval`
pol-003	Secret/key in payload	`deny`
pol-004	Rate limit exceeded	`flag`
pol-005	Risk score ≤ 20	`allow` freely
pol-006	Prompt injection detected	`deny`
pol-007	Same tool > 50 calls/60s	`flag`

Risk Score Guide

Score	Level	Action
0-14	Minimal	Proceed freely
15-39	Low	Proceed, log for audit
40-69	Medium	Flag and proceed with caution
70-89	High	Require human approval
90-100	Critical	Block execution

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.
