CIE indexes your codebase and provides semantic search, call graph analysis, and AI-powered code understanding through the Model Context Protocol (MCP).
Prerequisites: Docker and Docker Compose
Find code by meaning, not keywords:
Example output:
Trace how execution reaches any function:
Example output:
List all API endpoints automatically:
Example output:
Supports Go, Python, JavaScript, TypeScript, and more through Tree-sitter parsers.
Homebrew (macOS/Linux):
Script:
Manual download:
Download from GitHub Releases
Example output:
"Connection refused" - Ensure infrastructure is running: cie start
"CIE_BASE_URL not set" - The CLI should detect it if cie init was run correctly, but you can export it manually: export CIE_BASE_URL=http://localhost:9090
CIE can run as an MCP server for integration with Claude Code:
Configure in your Claude Code settings:
CIE uses a YAML configuration file (.cie/project.yaml):
Note: The llm section is optional. Without it, cie_analyze returns raw analysis data. With it configured, you get synthesized narrative summaries.
When running as an MCP server, CIE provides 20+ tools organized by category:
For detailed documentation of each tool with examples, see Tools Reference
CIE stores indexed data locally in ~/.cie/data/<project_id>/ using CozoDB with RocksDB backend. This ensures:
CIE supports multiple embedding providers:
CIE uses a client-server architecture where the heavy lifting runs in Docker:
Key Components:
Code Structure:
For in-depth architecture details, see Architecture Guide.
CIE uses a two-tier testing approach:
Unit Tests (default) - Fast in-memory tests, no CozoDB installation required:
Integration Tests - Use Docker containers with CozoDB:
The testcontainer infrastructure automatically handles:
For detailed testing documentation, see docs/testing.md.
Use the CIE testing helpers for easy test setup:
