Morph Search

Morph Codebase Search

Fast, AI-powered codebase search using WarpGrep. 20x faster than traditional grep.

When to Use

• Search codebase for patterns, function names, variables
• Find code across large codebases quickly
• Edit files programmatically

Usage

Search for code patterns

uv run python -m runtime.harness scripts/mcp/morph_search.py \
    --search "authentication" --path "."

Search with regex

uv run python -m runtime.harness scripts/mcp/morph_search.py \
    --search "def.*login" --path "./src"

Edit a file

uv run python -m runtime.harness scripts/mcp/morph_search.py \
    --edit "/path/to/file.py" --content "new content"

Parameters

| Parameter | Description |

|-----------|-------------|

| --search | Search query/pattern |

| --path | Directory to search (default: .) |

| --edit | File path to edit |

Examples

# Find all async functions
uv run python -m runtime.harness scripts/mcp/morph_search.py \
    --search "async def" --path "./src"

# Search for imports
uv run python -m runtime.harness scripts/mcp/morph_search.py \
    --search "from fastapi import" --path "."
