axiom-graph 1.0.3

Project knowledge indexer for AI agents — scans code, tracks documentation staleness, and serves a knowledge graph to AI agents via MCP

Cortex

A project knowledge indexer that scans your codebase, builds a structured graph of modules, functions, classes, and documentation, and tracks when docs drift from the code they describe. Designed for AI-assisted development -- cortex gives agents structured access to your project through the Model Context Protocol (MCP).

Quick Start

pip install axiom-graph[viz]

cortex init /path/to/your/project    # scan and build the index
cortex check /path/to/your/project   # see what's stale
cortex viz /path/to/your/project     # launch the dashboard

Features

• Knowledge graph -- indexes Python (and JS/TS via tree-sitter) into nodes and edges: functions, modules, classes, docs, tests, and their relationships
• Staleness detection -- two-dimensional tracking (own content changes + linked dependency changes) with transitive propagation through doc chains
• MCP server -- 29 tools for AI agents to search, read, navigate, and modify the index over the Model Context Protocol
• Viz dashboard -- interactive browser UI with graph view, list view, doc manager, workflow explorer, and detail panels
• DocJSON -- structured documentation format that links sections to code nodes, enabling automated drift detection
• dFlow integration -- optional workflow/task decorators with step markers, indexed alongside code
• CI gate -- cortex check --fail-on any in GitHub Actions prevents stale docs from merging

MCP Server Setup

The MCP server is how AI agents interact with cortex. It uses stdio transport.

Claude Code

Create .mcp.json in your project root:

{
  "mcpServers": {
    "cortex": {
      "type": "stdio",
      "command": "/path/to/your/venv/bin/python",
      "args": ["-m", "cortex.mcp_server"],
      "env": {
        "CORTEX_LOG_LEVEL": "INFO"
      }
    }
  }
}

VS Code (Copilot / Continue)

Add to .vscode/settings.json:

{
  "mcp.servers": {
    "cortex": {
      "command": "/path/to/your/venv/bin/python",
      "args": ["-m", "cortex.mcp_server"],
      "env": {
        "CORTEX_LOG_LEVEL": "INFO"
      }
    }
  }
}

Any MCP client

The entry point is cortex-mcp (installed as a console script) or python -m cortex.mcp_server. Both use stdio transport -- JSON-RPC on stdin/stdout, logs on stderr.

Logging

Variable	Default	Description
CORTEX_LOG_LEVEL	INFO	DEBUG, INFO, WARNING, ERROR
CORTEX_LOG_FILE	(none)	Path to a rotating log file (5 MB max, 2 backups)

Set CORTEX_LOG_LEVEL=DEBUG to see tool entry/exit timing, SQL queries, and build details. Logs always go to stderr; CORTEX_LOG_FILE adds a file copy.

Documentation

Full documentation is available as a consumer docs site:

pip install axiom-graph[viz]              # includes mkdocs-material
cortex render-site /path/to/project  # generates site/ directory
cortex render-site /path/to/project --serve  # live preview at localhost:8000
