MCP server and CLI for detecting, redacting, and auditing PHI before medical text is sent to AI
agents.

`phi-guard-mcp` is healthcare AI safety infrastructure, not a clinical product. It is a local,
rule-based guardrail that helps developers identify PHI-like identifiers in plain text, redact them
with stable placeholders, and produce audit-friendly JSON before content reaches an AI agent or MCP
workflow.

Proof points for maintainers:

- Synthetic benchmark with exact-match PHI finding evaluation.
- Safe Harbor mapping audit fields for review workflows.
- CI privacy gate that blocks PHI-like identifiers in maintained source and docs.
- CLI, Python API, and MCP stdio tools sharing one stable JSON result model.

Important scope limits:

- Not for diagnosis, treatment, triage, medical advice, or medication recommendations.
- Not a HIPAA compliance guarantee and not a substitute for legal, privacy, or security review.
- Not an FDA-regulated clinical decision support or device software function.
- Do not test with real patient records. The examples in this repo are synthetic.

The project aligns its documentation vocabulary with HHS HIPAA de-identification concepts such as
Safe Harbor and Expert Determination, while intentionally avoiding clinical decision support scope.
