HealthClaw Guardrails (healthclaw.io) — FHIR agent guardrails for clinical data access via MCP. Supports FHIR R4 US Core v9 (stable) and FHIR R6 ballot3 (experimental). Use when: (1) Reading patient data through MCP tools with automatic PHI redaction, (2) Writing clinical resources with two-phase propose/commit and step-up authorization, (3) Querying observation statistics or recent lab results, (4) Evaluating R6 Permission resources for access control decisions, (5) Auditing agent access to…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# HealthClaw Guardrails A [healthclaw.io](https://healthclaw.io) open source project. Reference implementation of security and compliance patterns for AI agent access to FHIR data via MCP. Supports **FHIR R4 US Core v9** (stable) and **FHIR R6 v6.0.0-ballot3** (experimental). **This is a runtime guardrail layer, not a knowledge skill.** It sits between any AI agent and FHIR data (local or upstream), enforcing PHI redaction, audit trails, step-up authorization, and tenant isolation on every request. ## When to Use This Skill - You need to read, search, or write FHIR clinical resources through MCP - You need PHI to be automatically redacted before the agent sees it - You need an immutable audit trail of all agent access - You need step-up authorization gates on write operations - You need to evaluate R6 Permission resources for access control ## MCP Tools Available (12) ### Read Tools (no step-up required) | Tool | Purpose | |------|---------| | `context.get` | Retrieve a pre-built context envelope with patient-centric resources | | `fhir.read` | Read a single FHIR resource by type and ID (auto-redacted) | …

How to install
mdr add aks129/healthclawguardrails/fhir-r6-guardrails@sha256:777ffa66ddb6a46aThe line at the top of this page pins the label git:20260924.b9d26a3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
