0Pirate

The Zero-Knowledge AI Proxy for Enterprise Code

🏴‍☠️ Developers love AI. InfoSec hates it.

Copilot and Cursor send your proprietary code, PII, and API keys directly to third-party servers. For many enterprises, this is an unacceptable security risk.

"Why not just use a local LLM like Ollama?" Because local 8B models cannot compete with the coding intelligence of Claude 3.5 Sonnet or GPT-4o. If you use a local model, you sacrifice intelligence for privacy.

0Pirate is the solution.

0Pirate is an open-source, local-first redaction proxy. It sits between your codebase and frontier LLMs. Before a single line of code leaves your machine, 0Pirate abstracts proprietary logic and redacts secrets. The AI only sees generic placeholder variables. Once the AI returns a generated solution, 0Pirate reverses the abstraction locally.

You get the intelligence of Claude 3.5 Sonnet with the privacy of a local LLM.

✨ Features

• 🛡️ Client-Side Redaction: Secrets (AWS keys, passwords) and PII (emails, phone numbers) never leave your machine.
• 🧩 Abstracted Logic: Proprietary function names (calculate_black_scholes_margin()) are mapped to generic tokens (func_A()) before hitting the LLM.
• ⚡ Multi-Model Support: Plug in OpenAI, Anthropic, Google Gemini, DeepSeek.
• 🤖 Agentic Integration (Cursor / Claude Code): Expose 0Pirate as an MCP Server directly inside your favorite IDE.
• 📦 GitHub Action & Pre-Commit Hooks: Automatically review Pull Requests and local commits with Zero-Knowledge security.
• 🔒 COVE Hardening (Optional): Run generated code in an isolated Docker sandbox before accepting it.

🤖 The Agentic Era: Use with Cursor & Claude

Don't want to use our CLI? You don't have to. 0Pirate natively integrates with agentic IDEs like Cursor and Claude Code via the Model Context Protocol (MCP).

By adding 0Pirate as an MCP Server, you force your AI Agent to operate inside a zero-knowledge sandbox. When Cursor tries to read your code, 0Pirate intercepts the read, redacts it, and hands Cursor the safe version.

Setting up the MCP Server

# Add to your cursor/claude config:
{
  "mcpServers": {
    "0pirate-secure-proxy": {
      "command": "python3",
      "args": ["/path/to/0pirate/cli/mcp_server.py"]
    }
  }
}

Now, whenever you tell Cursor to refactor a file, it will use 0Pirate's read_secure_file tool automatically!

🚀 Quickstart (The 1-Minute Rule)
