+# MCP Tools Bug Fix - newline parameter
+
+## Issue
+The MCP edit_file tool in `src/mcp_client.py` was using `newline=""` in `read_text()` and `write_text()` calls. This parameter is NOT supported by Python's `pathlib.Path` methods before Python 3.10.
+
+## Fix Applied
+Removed all `newline=""` parameters from:
+- `p.read_text(encoding="utf-8", newline="")` → `p.read_text(encoding="utf-8")`
+- `p.write_text(content, encoding="utf-8", newline="")` → `p.write_text(content, encoding="utf-8")`
+
+## Prevention
+When editing Python files via MCP tools, always use the standard `encoding="utf-8"` without the `newline` parameter, as Python's pathlib doesn't support it until 3.10+.
