Path Validation And Security Boundary Enforcement

MCP server for filesystem access

Unique: Implements multi-layer path validation (normalization, allowlist/denylist, symlink resolution) at the MCP server level before any filesystem operation executes, preventing directory traversal at the protocol boundary rather than relying on OS permissions alone

vs others: More robust than OS-level permissions alone because it validates paths at the application layer, catching traversal attempts that might bypass filesystem ACLs, and provides explicit configuration for multi-tenant or restricted-access scenarios
