Claude Code has an MCP security problem — and your developers are already using it
Claude Code is Anthropic’s AI coding assistant — a command-line tool that developers are adopting fast.
AI Summary
Researchers at Mitiga Labs disclosed an attack chain targeting Anthropic’s Claude Code, an AI coding assistant that uses the Model Context Protocol to connect to services like Jira, Confluence, GitHub, databases and internal APIs. When a developer links a service, Claude Code runs an OAuth flow, stores the resulting bearer token in plaintext in a local configuration file (~/.claude.json). The researchers showed that a malicious npm package can execute a post‑install hook that silently rewrites this file, giving an attacker control over MCP traffic. This vulnerability highlights a risk for teams using Claude Code in development environments.
