## Breaking Changes
### search_files Tool Changes (February 2025)
The `search_files` tool has been updated with the following breaking changes:
- **Parameter change**: The `pattern` parameter (string) has been replaced with `patterns` parameter (string[])
- **Behavior change**: Now uses glob pattern matching exclusively instead of mixed glob/substring matching
- **Migration**: Update calls from `{"pattern": "*.js"}` to `{"patterns": ["*.js"]}` and ensure patterns use proper glob syntax
## Directory Access Control
The server uses a flexible directory access control system. Directories can be specified via command-line arguments or dynamically via [Roots](https://modelcontextprotocol.io/docs/learn/client-concepts#roots).
