Reference

Variable	Required	Default	Description
`ANTHROPIC_API_KEY`	At least one API key	—	API key for Anthropic (Claude) models. Get one at console.anthropic.com.
`OPENAI_API_KEY`	At least one API key	—	API key for OpenAI (GPT-4o) models. Get one at platform.openai.com.
`GHIDRA_INSTALL_DIR`	No	Auto-detected	Path to your Ghidra installation directory. Only needed if auto-detection fails.
`JAVA_HOME`	No	Auto-detected	Path to your JDK installation. Only needed if auto-detection fails.
`KONG_CONFIG_DIR`	No	`~/.config/kong`	Override the directory where Kong stores its configuration database.

API keys

You need at least one API key — either Anthropic or OpenAI. If you’re using a custom endpoint, no API key is required (or you can set one during kong setup if your endpoint requires authentication).

# Set your API key(s)
export ANTHROPIC_API_KEY="sk-ant-api03-..."
export OPENAI_API_KEY="sk-..."

Add these to your shell profile (~/.zshrc, ~/.bashrc) so they persist across sessions.

Ghidra and JDK auto-detection

Kong searches common installation paths for Ghidra and JDK. You only need to set GHIDRA_INSTALL_DIR and JAVA_HOME if:

You installed Ghidra in a non-standard location
Auto-detection picks the wrong version
You’re running in a container or CI environment

export GHIDRA_INSTALL_DIR="/opt/ghidra_11.3"
export JAVA_HOME="/usr/lib/jvm/java-21-openjdk"

Config directory

Kong stores its configuration (enabled providers, default provider, custom endpoint settings) in an SQLite database at ~/.config/kong/config.db. Override the location:

export KONG_CONFIG_DIR="/path/to/custom/config"
