kai · Summary

Kai is a semantic analysis engine for code changes that provides MCP tools for call graphs, dependencies, and impact analysis.

filesystem · Summary

kai · Use cases

Selective CI - only run tests impacted by code changes
AI code context - provide semantic understanding to AI assistants
Code reviews - show what changed functionally rather than just line diffs

filesystem · Use cases

Enable AI models to read and write project files during development
Allow Claude or other MCP clients to browse and analyze codebases
Provide secure sandboxed access to specific directories for content generation

kai · Install

# curl
curl -sSL https://get.kaicontext.com | sh

# Homebrew
brew install kaicontext/kai/kai

For Claude Code:

claude mcp add kai -- kai mcp serve
