My AI Agent Stole My API Keys. Yours Is Next
My AI agent stole my API keys. Not in some dystopian future scenario. In the real world last month. Over 29 million secrets leaked on GitHub in 2025 alone, and AI agents are making that number worse. If you're still pasting credentials into prompts or trusting your computer use agent to keep your secrets safe, you're not just being careless. You're gambling with everything.
The 29 Million Secrets Problem
GitGuardian's 2026 State of Secrets Sprawl report shows AI coding tools doubled the rate of leaked secrets. We're talking about 29 million exposed API keys, tokens, database credentials, and other secrets that should never see the light of day. The problem isn't that AI agents are bad. The problem is that most AI agents treat secrets like user input. They log them. They repeat them. They leak them into public repositories. OpenClaw and similar personal AI agents have already been caught leaking plaintext API keys and credentials. Researchers found 280+ leaky skills that expose sensitive data. One skill can expose your entire company's production database credentials just by being loaded into an agent environment. This isn't theoretical. It's happening every day.
Why Credential Handling Is Broken
- ●Most computer use agents log prompts and outputs for training. Your API keys are in those logs.
- ●Agents share environments between users. If one user's agent leaks credentials, everyone in that environment loses.
- ●Secrets management tools are designed for humans. They're not designed for agents that need to log in, click around, and work across multiple apps.
- ●OpenAI Operator and Anthropic Computer Use both collect user data externally. That's great for their models, terrible for your security posture.
OpenClaw has already been reported to leak plaintext API keys and credentials that threat actors can steal via prompt injection. This is exactly the kind of nightmare scenario security teams are terrified of.
The Model Context Protocol Disaster
The Model Context Protocol (MCP) was supposed to be the standard for connecting AI agents to external systems. Instead it's become a credential leak factory. More than half of MCP servers rely on hardcoded credentials or weak authentication. Security researchers found that counterfeit MCP servers can impersonate legitimate services and steal credentials from agents that trust them. MCP amplifies security risk through two primary mechanisms. First, it makes it easy for agents to connect to many different systems. Second, it lacks standardized secrets management. An agent can hit 50 different MCP servers in a workflow, and if one of them is compromised, all those credentials are at risk. This is why the Docker blog and others are warning that MCP security issues threaten AI infrastructure. The protocol is growing faster than its security model can keep up.
Why Coasty Exists (and Solves This)
Coasty is different because it treats secrets management as a first-class concern, not an afterthought. Our computer use agent doesn't just paste credentials. It uses your own BYOK secrets store, so your credentials never touch our systems. You control the encryption, you control the access, and you control who can see what. Coasty runs on real desktops, browsers, and terminals. It's not just making API calls. It's actually doing the work. That means you can audit every action, every login, every credential use. If something looks wrong, you can shut it down immediately. Coasty scored 82% on OSWorld, the leading benchmark for computer use agents. Anthropic's Computer Use scored 22%, OpenAI Operator scored 38%. Those benchmarks matter because they measure real-world performance, not marketing hype. But performance without security is just a faster way to destroy your infrastructure.
The era of pasting API keys into AI prompts is over. It was never a good idea to begin with. If you're still trusting your computer use agent with raw secrets, you're putting your entire organization at risk. Use Coasty.ai. It's the only computer use agent that gives you BYOK secrets management and real OS-level control. Stop leaking secrets. Start shipping value. Go to coasty.ai and see for yourself why 82% on OSWorld isn't just a number. It's the difference between an agent that actually works and one that's just another security liability.
