Pull Request Overview
This PR introduces tool-specific configuration support via a new --tools flag, enabling users to specify individual tools instead of (or in addition to) toolsets. Users can now compose their MCP server configuration using --tools, --toolsets, --read-only, and --dynamic-toolsets flags in any combination.
Key changes:
- Added
--toolsflag for specifying individual tools by name - Implemented additive composition logic where tools and toolsets can be combined
- Maintained read-only mode enforcement (write tools are skipped even if explicitly requested)
