find_similar_code
Identify similar code snippets within a project by analyzing syntax and structure. Specify a code snippet, language, and similarity threshold to retrieve matching code locations for efficient code comparison and review.
Instructions
Find similar code to a snippet.
Args:
project: Project name
snippet: Code snippet to find
language: Language of the snippet
threshold: Similarity threshold (0.0-1.0)
max_results: Maximum number of results
Returns:
List of similar code locations

Implementation Reference
- Handler and registration for the find_similar_code MCP tool. Defines the tool function with @mcp_server.tool() decorator and implements logic using text search on project files filtered by language extension.
