CocoIndex Code MCP Server

MCP server integrating CocoIndex for semantic code search and indexing. CocoIndex provides real-time incremental indexing of codebases with semantic search capabilities. Enables AI agents to perform semantic code search, find relevant functions/classes, and query code understanding across large repositories.

Best When

A development team using CocoIndex for codebase indexing wants AI agents to perform semantic code search and navigate large codebases using natural language queries.

Avoid When

You don't have CocoIndex set up. CocoIndex requires embedding and indexing infrastructure. For simple pattern search, use standard tools.

Use Cases

• Semantic code search across a codebase from AI coding assistance agents
• Finding relevant functions and code patterns using natural language queries
• Indexing codebases for AI agents to understand code structure and relationships
• Codebase navigation and exploration using semantic similarity search

Not For

• Teams not using CocoIndex for code indexing (requires CocoIndex setup)
• Simple grep-style code search (use standard grep/ripgrep tools instead)
• Non-code content indexing
