relay

The primary security consideration is that Relay's core functionality involves allowing users to define and execute arbitrary commands and arguments for the MCP servers it manages. While essential for its purpose, this grants a high degree of control over the user's system, meaning users must exercise extreme caution when adding or configuring servers, as malicious or improperly configured commands could lead to unintended system access or data manipulation. Additionally, the current implementation (based on `src-tauri/src/models/server.rs` and `src-tauri/src/commands/servers.rs`) stores environment variables (`env`) as plain JSON strings within the local SQLite database. If these `env` strings contain sensitive credentials (e.g., API keys, tokens), they would be stored unencrypted, posing a risk if the local database file is compromised. Although `docs/03-API-SPECIFICATION.md` mentions `env_credentials` and a `KeychainService` for more secure storage, these are not fully implemented in the provided Rust backend code for server CRUD operations, indicating a potential vulnerability for sensitive data.
