Key features
- Instant symbol search — Find any function, class or type with exact file and line location in milliseconds.
- Impact analysis — Get full dependency chains and blast-radius of a change instantly.
- Dead code detection — Identify exports that are never imported for safe removal.
- Team-wide knowledge graph — All AI assistants query the same graph, ensuring consistent context.
- MCP server integration — Standard Model Context Protocol lets any compatible AI agent query the graph.
- CI/CD sync — Keep the code graph up-to-date automatically through CI/CD pipelines.
- Privacy-by-design — Only structural metadata is uploaded; source code never leaves the machine.
- Code graph visualization — Visual view of call graphs and dependencies for human inspection.
Use cases
- Rename a class and automatically update all references across the codebase.
- Assess what modules break before committing a refactor.
- Locate the definition of a symbol without grepping through files.
- Detect and remove dead or unused code safely.
- Provide consistent code context to multiple AI pair-programming agents.

- Constellation vs Cursor: Cursor is an AI-powered editor; Constellation provides a separate code graph service for any agent.
- Constellation vs Tabnine: Tabnine offers AI suggestions but lacks a shared structural graph for impact analysis.
- Constellation vs Cline: Cline is an open-source autonomous coding agent; Constellation supplies the underlying code intelligence it can consume.
Constellation FAQ
What is Constellation?+
Constellation is a code-intelligence platform that builds a structural map of your codebase for AI agents to query via MCP.
Does Constellation see my source code?+
No. It only processes structural metadata such as symbols and relationships; the actual source never leaves your machine.
How does Constellation work?+
The CLI parses code locally, uploads only metadata, then AI agents query the resulting knowledge graph through MCP.
Which AI coding agents work with Constellation?+
Any agent that supports MCP, including Claude Code, Copilot, Gemini, Codex, Tabnine, Cursor, VSCode and others.
What languages are supported?+
TypeScript, JavaScript, Python, Go and C# are currently indexed.
What can AI assistants do with Constellation?+
Perform impact analysis, locate symbols, trace dependencies, detect dead code, find circular dependencies and get architecture overviews instantly.
