Quick Start

Install

pip install humanbound                       # CLI + SDK, core deps
pip install humanbound[engine]               # + OpenAI / Anthropic / Gemini providers
pip install humanbound[firewall]             # + humanbound-firewall runtime
pip install humanbound[engine,firewall]      # everything

CLI usage

# Configure your LLM provider
export HB_PROVIDER=openai
export HB_API_KEY=sk-...

# Run a security test
hb test --endpoint ./bot-config.json --repo . --wait

# View results
hb posture                         # security score (0-100, A-F)
hb logs                            # conversation logs
hb report -o report.html           # HTML report
hb guardrails -o rules.yaml        # firewall rules

Full air-gap with Ollama — zero external API calls:

export HB_PROVIDER=ollama
export HB_MODEL=llama3.1:8b
hb test --endpoint ./bot-config.json --scope ./scope.yaml --wait

Python SDK

# Compose your own test pipeline
bot = Bot(endpoint="https://my-agent/chat", api_key="...")

class Callbacks(EngineCallbacks):
    def on_finding(self, insight): ...
    def on_progress(self, pct): ...

runner = LocalRunner()
# See docs.humanbound.ai for the full example

What's shipping in 2.0

• Clean name: humanbound is the new PyPI install. The old humanbound-cli is a transitional stub that will be yanked after 2026-06-20.
• Public SDK namespace alongside the CLI — use the CLI or drive the engine from Python. Both share the same implementation, so they can't drift.
• Firewall integration: pip install humanbound[firewall] pulls the renamed humanbound-firewall (formerly hb-firewall) alongside the CLI.

See CHANGELOG.md for the full 2.0.0 release notes.
