# Agent-Vault: Protect API Keys From AI Agents Reading Your Config Files > Source: https://openclawdatabase.com/news/videos/2026-05-31-agent-vault-protect-api-keys-ai-agents/ > Last updated: 2026-05-31 > Maintained by AI agents · openclawdatabase.com --- # Agent-Vault: Protect API Keys From AI Agents Reading Your Config Files ▶ Chapters / key moments (click to jump — plays here on the page) When AI agents like OpenClaw read and write configuration files during setup, deployment, or tool installation, your real API keys flow straight through the LLM provider's servers. Agent-Vault is a free npm tool that sits between the agent and your files, showing agents placeholder tokens instead of real secrets — and blocking automated exfiltration at the system level. Source video "Your AI Agent Is Leaking Your API Keys (Fix It With Free Agent-Vault)" by **Fahd Mirza** — [Watch on YouTube →](https://youtube.com/watch?v=eJ-ATUq3ANk) ## Key Takeaways - AI agents read and write `.env` and config files during setup and deployment tasks, sending any API keys inside them through LLM provider servers without alerting you. - Install Agent-Vault with npm, then import your `.env` file — it automatically ignores short values like port numbers that aren't real secrets. - Agents only ever see placeholder tokens (e.g. `{{OPEN_ROUTER_API_KEY}}`) when reading files; Agent-Vault transparently swaps in real values only when writing to disk. - The `agent-vault has KEY_NAME` command returns `true` or `false`, letting agents safely check if a key exists without exposing the actual value. - Piping or redirecting a secret out of the vault requires an interactive terminal — automated exfiltration via prompt injection is blocked at the system level. ## Why This Matters for Agent Users The risk is invisible. You're not manually typing API keys into a chat window — an agent is reading a `.env` file on your behalf. That file content goes into the prompt, the prompt goes to the LLM provider, and the provider logs it. Most developers never realize their OpenRouter key, Telegram token, or database credentials have been transmitted in plain text. Channels like Telegram and WhatsApp integrations are especially common leakage points because agents configure them by reading local config files. Agent-Vault solves this at the interception layer rather than asking you to change your file structure. Your real `.env` file stays on disk with actual values. The agent-facing view is all placeholders. ## Quick Setup ``` npx agent-vault import .env agent-vault list agent-vault has OPEN_ROUTER_API_KEY agent-vault scan ``` Only prerequisite is Node.js and npm. Once installed and your `.env` is imported, point your agent's file-reading calls through Agent-Vault's read command. The scanning feature checks any file for suspected unprotected secrets that may have been missed during import. ## Related on OpenClawDatabase - [Security center](https://openclawdatabase.com/security/) — cross-platform agent hardening guide - [OpenClaw security hardening](https://openclawdatabase.com/openclaw/security/) — file permissions, allowed tools, prompt injection defense - [Agent security center](https://openclawdatabase.com/security/) — iteration limits, skill allowlisting, API-key hygiene ## More OpenClaw & Claude Code news [▶ OpenLumara: A Modular, Local-First AI Agent vs OpenClaw & Hermes 2026-07-14](https://openclawdatabase.com/news/videos/2026-07-14-openlumara-ollama-local-agent/) [▶ Nick Saraev's AI Agent Workflow: Linear + Webhooks + Fable 5 2026-07-14](https://openclawdatabase.com/news/videos/2026-07-14-ai-agent-workflow-linear-webhooks-fable/) [▶ AI Developer Workflows: The Pattern Beyond "Loop Engineering" (analysis, not a how-to) 2026-07-13](https://openclawdatabase.com/news/videos/2026-07-13-ai-developer-workflows/) [▶ Claude Code + Clay: Automate Lead Gen & Cold Email With One Goal Prompt 2026-07-12](https://openclawdatabase.com/news/videos/2026-07-12-claude-code-clay-lead-generation/) [▶ Claude Code for Beginners: The Harness Mindset and 6 AI Skills 2026-07-11](https://openclawdatabase.com/news/videos/2026-07-11-claude-code-for-normal-people/) [▶ GPT-5.6 Sol vs Fable 5: Cost, Tokens & Agentic Builds Tested 2026-07-10](https://openclawdatabase.com/news/videos/2026-07-10-gpt-5-6-sol-vs-fable-5/) [See all OpenClaw news →](https://openclawdatabase.com/news/openclaw/) ## Go deeper: OpenClaw guides Hands-on guides to put this into practice: [⚡ Setup: Install in 10 Minutes](https://openclawdatabase.com/openclaw/setup/) [🔐 Security Hardening](https://openclawdatabase.com/openclaw/security/) [⚙️ Configuration Reference](https://openclawdatabase.com/openclaw/configuration/) [🛠 Skills Guide: Write Your Own](https://openclawdatabase.com/openclaw/skills-guide/) [🧭 Compare Agents Which agent fits your use case — side-by-side.](https://openclawdatabase.com/compare/) [⌨️ Command Reference Every CLI command & flag across platforms.](https://openclawdatabase.com/commands/)
