Question 2

How does Indexer integrate with Large Language Models (LLMs)?

Accepted Answer

Indexer integrates seamlessly with any Model Context Protocol (MCP)-compatible LLM client (such as Claude Code). It exposes a rich set of tools for code search, repository management, and cross-repo analysis directly to the LLM, enabling advanced AI-driven code interactions.

Question 3

Does Indexer keep its code index updated automatically?

Accepted Answer

Yes, Indexer supports incremental updates. It tracks git commits and can reindex only the parts of repositories that have changed, ensuring your code index is always current without unnecessary full reindexing. It can also install Git hooks for automatic updates on pull.

Accepted Answer

Indexer (also known as MCP Indexer) is a software tool designed to index code repositories using semantic embeddings. Its primary purpose is to provide intelligent search and analysis capabilities, making code more accessible and understandable for LLM clients and AI coding agents.

Question 5

How does Indexer improve the productivity of AI coding agents?

Accepted Answer

Indexer significantly boosts AI agent productivity by enabling natural language queries to find relevant code by meaning, not just keywords. It also provides tools for finding symbol definitions, references, related code, and performs cross-repository analysis to detect dependencies and suggest missing repos.
