What is AgentShield and how does it secure AI coding agents?

AgentShield is a runtime defense and OS-level kernel sandbox (Bubblewrap on Linux, Landlock, Seatbelt on macOS, AppContainer on Windows) designed for autonomous AI agents like Claude Code, Cursor, and Windsurf. It intercepts process execution, redacts environment credentials (.env, AWS keys, GitHub tokens) before they reach the model, and replaces sensitive tokens with synthetic decoy honeytokens.

How does DevShelf help developers find tools and MCP servers?

DevShelf is an open-access catalog indexing 567+ verified developer tools, free APIs, and Model Context Protocol (MCP) servers with no login or paywalls. It offers 1-click Docker Compose configs, package install snippets, a terminal CLI, and an official MCP server for AI coding assistants.

How does DBShield protect production databases from AI agent queries?

DBShield acts as an air-gapped PostgreSQL wire proxy (protocol 3.0) and SQLite guardrail that intercepts destructive operations (DROP, TRUNCATE, UPDATE without WHERE), quarantines unindexed table scans, and triggers interactive two-man rule Slack/Teams approvals.

1. Zero-Leak Stream Gate

Sub-millisecond sliding window scrubs credentials across arbitrary chunk splits, fragmented byte packets, and multiline RSA/OpenSSH PEM keys.

2. Kernel-Level Isolation

Leverages Landlock and Bubblewrap (Linux) and Seatbelt (macOS) to deny process environment inspections, /proc pseudo-file dumps, and network leaks.

3. Tamper-Proof Audit Ledger

Every blocked attempt and sanitized egress stream is cryptographically hashed with SHA-256 HMAC chains for verifiable SOC 2 Type II audit proof.
