Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

The knowledge graph for your codebase — explore it visually, or let your AI agent query it.

Indexes any codebase into a structural knowledge graph — every dependency, call chain, cluster, and execution flow. Explore it through an interactive web dashboard with force-directed graph visualization, or expose it through MCP tools so AI agents get full structural understanding in every tool call.

Questions

What is the Axon MCP server?

Graph-powered code intelligence engine — indexes codebases into a knowledge graph, exposed via MCP tools for AI agents and a CLI for developers.

What tools does Axon expose?

11 in total: 9 read-only, 2 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Axon safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Axon need?

No credential environment variables were found in its source, so it appears to need none.

How does Axon run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as axon-ui at 0.1.0.

How current is this page?

The grade is for one exact copy of the source (460d4952f770), read on 2026-09-27. The repository is watched and re-audited when it changes.
