Why _disabled by default
MCP servers come from third parties. Their stability, scope, and security posture can change between releases. Shipping them disabled means installing the pack does not surprise you with extra processes, network calls, or write access. Move the entries you actually want from _disabled into mcpServers in your project's .mcp.json.
Filesystem MCP
We do not recommend a filesystem MCP server. Claude Code already ships first-class file tools (Read, Edit, Write, Glob, Grep) with permissions integration; a filesystem MCP server is redundant and adds attack surface.
Pair with safety-pack
When safety-pack is installed, the mcp-tool-allowlist hook will block any MCP tool that is not in CLAUDE_HARNESSES_MCP_ALLOW. Each server doc lists a starter allowlist string.
