modbender mirage-proxy for OpenClaw
Transparent secrets/PII filter between OpenClaw and LLM providers. Replaces sensitive data with plausible fakes — the LLM never knows.
GitHub: https://github.com/chandika/mirage-proxy
Quick Setup
Run the bundled setup script:
bash ~/.openclaw/workspace/skills/mirage-proxy/setup.sh
This downloads the binary, creates an auto-restart wrapper, starts the proxy, and verifies it's running.
To uninstall: bash ~/.openclaw/workspace/skills/mirage-proxy/setup.sh --uninstall
Configure OpenClaw Providers
After setup.sh succeeds, patch the OpenClaw config. Keep original providers AND add mirage versions for instant fallback:
{
"models": {
"mode": "merge",
"providers": {
"mirage-anthropic": {
"baseUrl": "http://127.0.0.1:8686/anthropic",
"api": "anthropic-messages",
"apiKey": "${ANTHROPIC_API_KEY}",
"models": [
{ "id": "claude-opus-4-6", "name": "Claude Opus 4.6 (mirage)", "api": "anthropic-messages", "reasoning": true, "input": ["text", "image"], "cost": {"input":0,"output":0,"cacheRead":0,"cacheWrite":0}, "contextWindow": 200000, "maxTokens": 32000 },
{ "id": "claude-sonnet-4-6", "name": "Claude Sonnet 4.6 (mirage)", "api": "anthropic-messages", "reasoning": true, "input": ["text", "image"], "cost": {"input":0,"output":0,"cacheRead":0,"cacheWrite":0}, "contextWindow": 200000, "maxTokens": 16000 },
{ "id": "claude-haiku-3-6", "name": "Claude Haiku 3.6 (mirage)", "api": "anthropic-messages", "reasoning": false, "input": ["text", "image"], "cost": {"input":0,"output":0,"cacheRead":0,"cacheWrite":0}, "contextWindow": 200000, "maxTokens": 8192 }
]
}
}
},
"agents": {
"defaults": {
"models": {
"anthropic/claude-opus-4-6": { "alias": "anthropic-opus" },
"anthropic/claude-sonnet-4-6": { "alias": "anthropic-sonnet" },
"anthropic/claude-haiku-3-6": { "alias": "anthropic-haiku" },
"mirage-anthropic/claude-opus-4-6": { "alias": "mirage-opus" },
"mirage-anthropic/claude-sonnet-4-6": { "alias": "mirage-sonnet" },
"mirage-anthropic/claude-haiku-3-6": { "alias": "mirage-haiku" }
}
}
}
}
OpenAI / Codex (OAuth)
For OAuth-based providers (no API key env var), override the built-in provider baseUrl instead of creating a custom provider:
{
"models": {
"mode": "merge",
"providers": {
"openai-codex": {
"baseUrl": "http://127.0.0.1:8686"
}
}
}
}
⚠️ Do NOT add "apiKey": "${OPENAI_API_KEY}" to custom providers unless the env var exists in your container — it will crash OpenClaw on startup.
Model Aliases
After config, switch with /model:
| Alias | Route |
|---|---|
anthropic-opus |
Direct to Anthropic |
mirage-opus |
Via mirage-proxy → Anthropic |
anthropic-sonnet |
Direct |
mirage-sonnet |
Via mirage |
codex |
Direct to OpenAI (or miraged if baseUrl overridden) |
Persistence
mirage-proxy dies on OpenClaw restarts. Two solutions:
Docker entrypoint (recommended):
# docker-compose.yml
command: sh -c "nohup /home/node/.openclaw/workspace/start-mirage.sh > /dev/null 2>&1 & exec openclaw start"
Heartbeat check (fallback): Add to HEARTBEAT.md:
curl -s -o /dev/null -w "%{http_code}" http://127.0.0.1:8686/
If 000 or connection refused → restart via start-mirage.sh.
Verify
# Proxy running?
curl -s -o /dev/null -w "%{http_code}" http://127.0.0.1:8686/
# Expect 502 (up, no path matched)
# Check redaction stats
tail -20 ~/.openclaw/workspace/mirage-proxy.log
# Look for: 🛡️ SECRET (AWS Access Key) [40 chars] → AKIA••••
