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
--content	New content for file (use with --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 "."

vs ast-grep

Tool	Best For
morph/warpgrep	Fast text/regex search (20x faster)
ast-grep	Structural code search (understands syntax)

MCP Server Required
