Full governance engine, 22 security rules, real-time Kill Feed — running on your own infrastructure in one click.
Fully managed. We'll handle infrastructure, updates, and scaling. Join the waitlist to get early access.
What to Expect
Here's exactly what happens after you click "Fork." No surprises, no hidden setup.
One click on Replit and your own Snapwire instance spins up. Full source code, your infrastructure, running in seconds.
Set your admin email, choose your first security rules, and configure budget limits. Guided walkthrough — no docs required.
Copy-paste a curl command, hit enter, and watch your first Snap-Card appear in the review queue. Instant proof it works.
curl -X POST /api/intercept -d '{"tool_name":"send_email"}'
Your dashboard lights up with real-time monitoring. All deterministic features — loop detection, spend tracking, kill switch — are active immediately.
How It Works
One line of code. Total visibility. Any agent framework.
Add our proxy URL to your agent's config. One environment variable and you're connected. Works with any LLM provider. Compatible with LangChain, CrewAI, OpenAI Assistants, and any MCP-compatible agent.
OPENAI_BASE_URL=https://your-snapwire/v1
Every tool call is intercepted and scored for risk. Snapwire checks for hallucination loops, spend overruns, data exfiltration, schema violations, and goal drift — all before the action executes.
High-risk actions are held for human review as Snap-Cards. One-click approve, deny, or edit-and-release. Automatic NIST IR 8596 compliance reports. Fix prompts generated for your agent. Every decision logged for audit.
Core Features
No configuration required. These work out of the box, with any LLM, on any framework.
Know exactly what your agent is spending, right now. Set daily and per-session limits. Get alerts before a runaway loop drains your credits — not after.
Agent repeats the same call 3 times in 30 seconds? Circuit broken, instantly. No more waking up to a $200 bill because your agent got stuck in a "thinking" loop overnight.
Your agent never touches a raw API key. Snapwire proxies credentials through revocable tokens. Revoke one tool, or hit the kill-switch to revoke everything in one click.
Runtime violations show up as cards with full context: what the agent tried, why it was stopped, and what rule triggered. Approve, deny, or trust the pattern for 24 hours.
Lock your agent's network boundary to trusted domains only. Block outbound HTTP and webhook calls to unapproved URLs before they happen.
Monitors extended thinking usage (Claude 3.7+). If your model burns 50k+ thinking tokens without a tool call, Snapwire fires a “Potential Logic Loop” warning before costs spiral.
Native JSON-RPC 2.0 support. Send standard MCP tools/call requests directly — Snapwire auto-detects the format. Works with Cursor, Replit, Claude, and any MCP-compliant agent.
NISTIR 8596-aligned compliance reports, Safety PDFs, and Impact Assessments — generated automatically from your audit data. Tag high-stakes tools for Colorado SB24-205. Manage governance via API with Governance-as-Code.
Point your agent's traffic at Snapwire's Sentinel Proxy. No SDK. No code changes. Just swap your API base URL. 60 seconds to full governance.
Supports OpenAI, Anthropic, MCP, A2A, and any JSON-RPC protocol. Three modes: Observe (silent audit), Audit (trace + log), Enforce (block + fail-closed).
Why Not Just a Sandbox?
AI agent security has two layers. Most teams only have one.
What sandboxes do
Keeps agents from touching your OS filesystem, host processes, or other containers. Essential for containment — but the agent still has full access to everything inside the sandbox.
Snapwire runs inside any container, any cloud, any sandbox. The two layers are complementary — not competing.

Snapwire provides the evidence-generation tools required for a "Reasonable Care" defense. The final configuration remains the sole responsibility of the Deployer.
Snapwire is a technical monitoring utility. All blocks, alerts, and signals generated are heuristic and advisory in nature. The final Duty of Care for all agent actions and budgetary releases remains solely with the human operator.
Reasonable Care Disclosure: Snapwire's Sentinel Sidecar is a Deterministic Security Gateway designed to provide continuous monitoring and algorithmic guardrails for autonomous agents. By utilizing Snapwire, the Deployer implements a "Reasonable Care" framework to prevent foreseeable algorithmic harm. Snapwire serves as a technical control-plane for compliance with NIST AI Agent Standards.
Infrastructure Intermediary: Snapwire operates as a Passive Security Intermediary (Reverse Proxy). It does not generate, modify, or assume responsibility for the underlying intent or output of the AI Model. Snapwire's liability is limited to the integrity of the gateway's execution of user-defined rules. Forensic logs serve as the Immutable Forensic Record of intent and delegation.
