axon
Graph-powered code intelligence engine — indexes codebases into a knowledge graph, exposed via MCP tools for AI agents and a CLI for developers.
Axon is an MCP server that transforms codebases into queryable knowledge graphs for AI agents and developers. It analyzes code structure, dependencies, call chains, and execution flows, then exposes this intelligence through MCP tools that agents can use to understand impact, find dead code, trace dependencies, and navigate architectural relationships. The server runs entirely locally with no cloud dependencies, indexing repositories in seconds and providing both an interactive web dashboard for human exploration and structured MCP tools for AI-driven code understanding.
Key Features
Use Cases
- 01AI agents analyzing blast radius before refactoring to understand which symbols will break with depth-grouped impact reports
- 02Code review assistants identifying dead code candidates and framework-aware exemptions across large codebases
- 03Agents discovering hidden dependencies through git change coupling that static analysis misses
- 04Exploring codebase architecture visually through interactive graphs with community overlays and flow animations
- 05Comparing branches at the symbol level to see added, modified, and removed functions and classes
- 06Semantic code search by concept rather than exact names, with results grouped by execution flow context

axon — FAQ
What is the Axon MCP server?+
Axon is an MCP server that indexes codebases into knowledge graphs and exposes structural intelligence through tools AI agents can query. It provides impact analysis, dead code detection, dependency tracing, and semantic search without sending data to the cloud.
How do I install and configure Axon for Claude Code?+
Install with 'pip install axoniq', navigate to your project directory, run 'axon analyze .' to index, then add the Axon MCP server configuration to your .mcp.json file in the project root. The server will automatically connect when Claude Code starts.
Which AI clients work with Axon?+
Axon works with any MCP-compatible client including Claude Code and Cursor. You configure it by adding the server command and args to your client's MCP settings file.
Does Axon require API keys or send data to the cloud?+
No, Axon runs entirely locally with zero cloud dependencies. All parsing, graph storage, embeddings, and search happen on your machine, and no API keys are required.
What languages does Axon support?+
Axon currently supports Python (.py), TypeScript (.ts, .tsx), and JavaScript (.js, .jsx, .mjs, .cjs) using tree-sitter parsers for accurate AST extraction.
