Your AI agents run untrusted code.
You already installed them. Your AI agents load MCP servers, ML models, and RAG corpora - every one is untrusted code or data. Oxvault finds the malicious ones and blocks the rest at runtime. Install in seconds. Zero telemetry. No account.
Aligned with
Scans and protects the tools your agents already use
One gate. Nothing untrusted gets through.
Every artifact your agent loads passes the gateway first. Safe calls forward. Attacks stop here — inspected in real time, before execution.
2 reached your agent · 1 stopped at the gate — inspected in real time, before execution.
What We Scan
Three artifacts. One engine.
Your agents don't just talk to LLMs - they load tools, weights, and documents. Each is an attack surface. We cover all three with the same deterministic scanner.
MCP Servers
Static + runtime security for MCP server code, tool descriptions, and JSON-RPC traffic.
- ✓12 published MCP CVEs reproduced
- ✓Tool description poisoning
- ✓Install hook detection
- ✓Supply chain audit
ML Models
Pickle is a remote shell. 23% of top HF models have been compromised. We disassemble opcodes without executing - and verify provenance.
- ✓Pickle opcode disassembly (no exec, CWE-502)
- ✓ONNX protobuf integrity + custom-op allowlist
- ✓Safetensors header overflow detection
- ✓Sigstore + OpenSSF Model Signing verification
- ✓Model card prompt injection (same engine as MCP)
- ✓Hugging Face resolver (oxvault scan hf:org/model)
RAG Pipelines
Inspect documents and embeddings for indirect prompt injection and retrieval-time attacks.
- ✓Embedding poisoning detection
- ✓Indirect prompt injection
- ✓Vector store integrity
- ✓Retrieval anomaly alerts
How Oxvault Works
Two products. One model.
The Scanner inspects artifacts before they load - source code, model weights, retrieval corpora. The Gateway proxies every tool call your agent makes at runtime. Every event is audit-logged.
Scanner - static analysis
150+ rules across MCP servers, ML models, and RAG documents. Pickle disassembly, ONNX validation, Sigstore verification, source SAST, credential detection.
Gateway - runtime proxy
Wraps your MCP clients. Every JSON-RPC call inspected. Shell injection, SSRF, credential theft, and rug-pulls blocked before execution.
Audit - full trail
Every tool call, every argument, every response logged with timestamps. Know exactly what your agents touched and when.

Security tools shouldn't phone home.
Cloud-based AI security platforms see everything you scan. We see nothing. Your code, your weights, your traffic stay on your machine.
No cloud, no telemetry
Runs entirely on your machine. Your code, your models, your traffic - none of it leaves your network.
No account required
Install with one curl command and scan. No signup, no email gate, no usage limits. Apache 2.0 licensed.
Standards-aligned
OpenSSF Model Signing, Sigstore, CycloneDX AIBOM, EU AI Act, NSA AI Supply Chain guidance. Conformant by design.
OSS core, paid runtime
Scanner is free forever. Pro adds runtime gateway, priority rules, and audit logging - for individuals and teams.
MCP Detections - Shipping Today
We found these in code you probably run
The examples below are real CRITICAL classes the scanner detects in production MCP servers. Model detections (pickle, ONNX, signatures) run on the same engine.
Command Injection
Blocks shell metacharacters, execSync with user input, os.system() calls. Found in Cloudflare, AWS, Microsoft, Desktop Commander.
Credential Theft
Detects hardcoded AWS keys, API tokens, private keys, Bearer tokens. Blocks policy violations targeting .ssh, .aws, .env files.
Tool Description Poisoning
Catches hidden instruction tags, unicode steganography, BiDi overrides, secrecy instructions, and cross-tool exfiltration patterns.
SSRF & Path Traversal
Blocks metadata IP access (169.254.169.254), RFC 1918 ranges, and ../ path sequences.
Rug Pull Detection
Tool descriptions are SHA-256 hashed at startup. Any mid-session change is flagged immediately. No other scanner does this.
Response Leakage
Scans server responses for AWS keys, GitHub PATs, private keys, JWTs, database connection strings.
Scan. Protect. Monitor.
One command, zero setup. Scan every installed MCP server and model in 30 seconds.
One command scans every MCP server and ML model already on your machine - and any target before you install it. 150+ rules check source code, tool descriptions, model weights, and credentials.
One command wraps all your MCP clients. Every tool call and every response inspected in real time. Injections blocked, credentials caught, exfiltration stopped.
Full audit trail of everything your AI agents do. See what was forwarded, what was blocked, and what triggered alerts - complete visibility.
How Oxvault compares
Capabilities, not benchmarks. The differences that decide where each tool fits.
| Cloud AI-security platforms | OSS point tools | Oxvault | |
|---|---|---|---|
| Runs on your machine · zero telemetry | – | ||
| No account, no signup to scan | – | ||
| MCP servers + ML models, one engine | Partial | Single artifact | |
| Runtime gateway — inspects live tool calls | Cloud proxy | – | |
| Wraps local MCP clients (stdio proxy) | – | – | |
| Rug-pull detection (hash-pinned tool descriptions) | – | – | |
| Entry price | $50K+ /yr | Free | $0 → $29/dev |
The catch most miss
Cloud platforms firewall LLM input/output. Point tools scan one artifact type, description-only. Oxvault covers the supply chain your agents actually load — locally first, then blocks what is left at runtime.
