grep

Grep Tool

Search file contents with regex. Uses ripgrep.

REQUIRED: pattern (regex pattern) OPTIONAL: path (directory/file), glob (file glob filter like "*.py"), ignoreCase (bool), literal (bool — treat pattern as literal text), context (lines of context before/after), limit (max matches, default 100)

RULES:

• Supports full regex syntax (unless literal: true)
• Use glob to filter by file type (e.g. ".py", ".js")
• Use limit to cap results; default 100
• Returns matching lines with file path and line number
• Good for finding function definitions, imports, references

EXAMPLE:

{"name": "Grep", "input": {"pattern": "def main", "glob": "*.py"}}

EXAMPLE with path:

{"name": "Grep", "input": {"pattern": "TODO|FIXME", "path": "/path/to/project/"}}

Workflow

1. Simple search: Pass a regex pattern to search all files
2. Filter by type: Use glob to limit to specific file extensions (e.g., "*.py")
3. Scope search: Use path to limit to a directory or specific file
4. Add context: Use context to see lines before/after matches
5. Cap results: Use limit to control output size (default 100)
