Plugs Into Modern AI Workflows

One environment variable. Every AI provider.

Purfect Shield works with every major AI provider and any OpenAI-compatible API. No SDK to install. No imports to add. No code changes per tool. Just point your base URL at localhost:6767 and Shield handles the rest.

How PurfectShield works
Provider Matrix

One proxy. Every provider your team uses.

Shield is provider-agnostic. It speaks the OpenAI API protocol and works with any compatible endpoint — cloud, local, or self-hosted.

Provider
Products
Setup
Anthropic
Claude, Claude Code
ANTHROPIC_BASE_URL → localhost:6767
OpenAI
GPT-4o, GPT-4, Codex
OPENAI_BASE_URL → localhost:6767
DeepSeek
DeepSeek-V3, DeepSeek-R1
DEEPSEEK_BASE_URL → localhost:6767
Local Models
Ollama, LM Studio, llama.cpp
OPENAI_BASE_URL → localhost:6767
Any OpenAI-compatible
Groq, Together, Fireworks, Mistral, etc.
OPENAI_BASE_URL → localhost:6767

BASE_URL → localhost:6767 · That's the entire integration

Claude MCP & Extensibility

Shield plugs into your existing AI workflow.

If you use Claude Code with MCP servers, Shield sits transparently in the egress path — no MCP config changes, no tool modifications. Every tool call, every file read, every API request flows through Shield's redaction engine automatically.

No MCP config changes

Shield sits transparently in the egress path between Claude Code and the API. Your MCP servers, tools, and configurations remain untouched.

All tools protected

Whether Claude Code calls filesystem tools, web fetch, or your custom MCP servers — every request transits through Shield's redaction engine.

Works with any MCP host

Claude Desktop, Claude Code, Cursor, Windsurf — if it speaks the Anthropic API, Shield protects it without per-tool configuration.

How it works with Claude Code

Claude Code reads tools from your MCP config and calls the Anthropic API. Set ANTHROPIC_BASE_URL=http://localhost:6767 and every request — whether it's a prompt, a tool result, or file content — passes through Shield before reaching Anthropic's servers. Secrets are tokenized. PII is redacted. Responses are rehydrated. Claude Code never knows Shield is there.

Zero-Code Integration

One environment variable. No SDK. No import.

Every other AI security tool requires you to install a library, import it in your code, and wrap every LLM call. Shield requires none of that. It sits on the wire — your code doesn't even know it's there.

No SDK

No pip install, no npm package, no library dependency. Shield is a standalone Go binary that runs on your infrastructure.

No Import

No import statements. No middleware registration. No client wrapping. Your application code stays exactly as it is.

No Per-Tool Config

Claude Code, Cursor, Windsurf, custom scripts — all protected with one BASE_URL change. No per-tool configuration needed.

Infrastructure-Level

Deploy Shield once on your network. Every AI call from every developer and every tool is protected — automatically.

One variable. Ten minutes. Protected.

We'll deploy Shield on your infrastructure and integrate it with your existing AI providers — Claude, OpenAI, DeepSeek, local models — in a single session. Your team keeps using the tools they know. Shield handles the security transparently.
