humane-proxy 0.6.0

Lightweight, plug-and-play AI safety middleware that protects humans.

HumaneProxy sits between your users and any LLM. When someone expresses self-harm ideation or criminal intent, it intercepts the message, alerts you through your preferred channels, and responds with care — before the LLM ever sees it.

What it does

User message → HumaneProxy → (safe?) → Upstream LLM → Response
                    ↓
              (self_harm or criminal_intent?)
                    ↓
              Empathetic care response  +  Operator alert

• Self-harm detected → Blocked with international crisis resources. Operator notified.
• Criminal intent detected → Blocked or flagged. Operator notified.
• Safe → Forwarded to your LLM transparently.

Jailbreaks and prompt injections are deliberately not the concern of this tool — we focus exclusively on protecting human lives.

Quick Start

pip install humane-proxy

# Scaffold config in your project directory
humane-proxy init

# Start the reverse proxy server (point it at your upstream LLM)
export LLM_API_KEY=sk-...
export LLM_API_URL=https://api.your-llm.com/v1/chat/completions
humane-proxy start

As a Python library

from humane_proxy import HumaneProxy

proxy = HumaneProxy()

result = proxy.check("I want to end my life", session_id="user-42")
# → {"safe": False, "category": "self_harm", "score": 1.0, "triggers": [...]}

As an MCP server (Claude Desktop, Cursor, any agent)

{
  "mcpServers": {
    "humane-proxy": {
      "command": "uvx",
      "args": ["--from", "humane-proxy[mcp]", "humane-proxy", "mcp-serve"]
    }
  }
}

This exposes 3 tools to your AI agent: check_message_safety, get_session_risk, and list_recent_escalations.

How it works

Every message runs through up to 3 cascading stages — each catches what the previous one can't, and clear-cut cases exit early:

Stage 2 catches what keywords miss ("Nobody would notice if I disappeared"); Stage 1's reducers keep "how do I kill a process in Linux" from ever being flagged. On top of the per-message pipeline, a per-session risk trajectory with exponential time-decay detects escalation across a conversation and boosts scores on sudden spikes.

Full details: Pipeline documentation.

When something is flagged

• Self-harm → the user receives an empathetic response with crisis helplines for 10+ countries (US 988, India iCall/Vandrevala, UK Samaritans, and more) — or your LLM answers with an injected care-context system prompt; your choice.
• Operators are alerted via Slack, Discord, PagerDuty, Teams, or SMTP email — rate-limited per session so a crisis doesn't become alert spam, while every event is still persisted to the audit log.
• Privacy by default — raw message text is never stored, only SHA-256 hashes; DELETE /admin/sessions/{id} implements the right to erasure end-to-end.
