## ⚡ What is Bartholomew Guard?

Bartholomew Guard is an in-process safety seam for AI developer agents (Cursor Composer, Windsurf, Claude Code, AutoGen, CrewAI, LangGraph). It intercepts tool invocations in memory before commands touch the filesystem, database, or network:

- **Catastrophic Execution Blocking**: Blocks `rm -rf`, `DROP TABLE`, and credential dumping in `<35 microseconds`.
- **Dynamic Spend & Retry Caps**: Enforces strict session spend caps and prevents infinite agent loops.
- **Model Context Protocol (MCP) Gateway**: Seamlessly bridges your local IDE agents to compliant execution boundaries.
- **SOC 2 Type II Merkle Receipts**: Cryptographically signs every decision with Ed25519 signatures.

## 🚀 Quickstart

1. Install this extension in **Cursor** or **VS Code**.
2. Press `Ctrl+Shift+P` (or `Cmd+Shift+P` on macOS) and run:
   ```text
   Bartholomew: Auto-Configure MCP Gateway in Cursor / VS Code
   ```
3. Your local Cursor agent will automatically be guarded against destructive tool calls!
