mcpguard Secures AI Agent API Keys

mcpguard addresses a critical security vulnerability in AI agent deployments: the storage of API keys in plaintext. The tool tackles the problem that over half of MCP servers expose API keys in config files, leading to potential breaches. By scanning MCP configurations, mcpguard migrates plaintext credentials to an encrypted OS keychain, replacing them with secure references. This prevents keys from being committed to git repositories, shared across machines, or exposed in data breaches. The tool operates locally, ensuring no cloud synchronization or network calls, and its open-source nature promotes transparency and community-driven security. mcpguard supports various MCP configurations, including Claude Desktop and Cursor, and offers features for auditing, migrating, adding, and listing credentials. While mcpguard significantly enhances API key security, developers must still practice good security hygiene, such as rotating exposed keys and reviewing git history for accidental commits.
