What it is

This tool provides a MCP server that enables developers to perform semantic code searches with AST-aware chunking and vector embeddings, enhancing the efficiency of code retrieval and understanding.

This tool stands out by offering a self-hosted, AST-aware semantic code search solution that leverages vector embeddings to provide precise and contextually relevant results.

When it fits — and when it doesn’t

A good fit for

  • JavaScript/TypeScript developers who need precise, semantic-aware code searches within their projects

  • Teams that require a self-hosted solution for sensitive or proprietary codebases

  • Projects aiming to integrate AI-driven search capabilities into their development tools

Look elsewhere if

  • Developers looking for cloud-based solutions with managed services

  • Users who need real-time streaming capabilities (this tool is batch-oriented)

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited language support beyond JavaScript/Python

    Primary focus on JavaScript and Python, other languages not well-supported

  2. 02

    Performance issues with large codebases

    AST processing can be slow for very large repositories

What it does well

  • AST-aware chunking for precise code analysis

  • Vector embeddings for semantic search capabilities

  • Self-hosted MCP server for customizable deployment
