Usage — step by step
breachwatch is a personal breach aggregator that triages and risk-scores exposures from local sources (HIBP / DeHashed / stealer logs).
- Install:
pip install -e . - Triage from a JSON config describing identities + sources:
breachwatch triage config.json - Filter by severity and read JSON output:
breachwatch triage config.json --min-severity medium --format json - Use the exit code —
--fail-onreturns exit code 2 when any exposure meets/exceeds the given severity:breachwatch triage config.json --fail-on high - Automate in cron/CI:
breachwatch triage config.json --format json --fail-on high > exposures.json

Why breachwatch?
Personal breach aggregator — HIBP + DeHashed + stealer-log triage — without standing up heavyweight infrastructure.
breachwatch is single-purpose, scriptable, and self-hostable: point it at a target, get prioritized results in the format your workflow already speaks (table · JSON · SARIF), gate CI on it, and let agents drive it over MCP.
Features

Quick start
pip install cognis-breachwatch
breachwatch --version
breachwatch scan . # scan current project
breachwatch scan . --format json # machine-readable
breachwatch scan . --fail-on high # CI gate (non-zero exit)
Example
$ breachwatch scan .
[HIGH ] BRE-001 example finding (./src/app.py)
[MEDIUM ] BRE-002 another signal (./config.yaml)

Use it from any AI stack
breachwatch is interoperable with every popular way of using AI:
- MCP server —
breachwatch mcp(Claude Desktop, Cursor, Cognis.Studio, uncensored-fleet) - OpenAI-compatible / JSON — pipe
breachwatch scan . --format jsoninto any agent or LLM - LangChain · CrewAI · AutoGen · LlamaIndex — wrap the CLI/JSON as a tool in one line
- CI / scripts — exit codes + SARIF for non-AI pipelines
How it compares
| Cognis breachwatch | typical tools | |
|---|---|---|
| Self-hostable, no account | ✅ | varies |
| Single command, zero config | ✅ | ⚠️ |
| JSON + SARIF for CI | ✅ | varies |
| MCP-native (AI agents) | ✅ | ❌ |
| Polyglot ports (JS/Go/Rust) | ✅ | ❌ |
| Open license | ✅ COCL | varies |
Integrations
Pipes into your stack: SARIF for code-scanning, JSON for anything, an MCP server (breachwatch mcp) for AI agents, and a webhook forwarder for SIEM/Slack/Jira. See docs/INTEGRATIONS.md.
