AI Agent Controls for Healthcare and Clinical Data

Industry Context

Healthcare organizations are deploying AI agents for clinical documentation assistance, medical coding automation, patient scheduling optimization, and research data analysis. These agents operate in environments containing protected health information (PHI), electronic health records (EHR), and clinical trial data. A single unauthorized agent action — reading a patient record, sending data to an unapproved endpoint, or modifying a clinical note — can trigger HIPAA violations with penalties up to $2.13 million per violation category per year.

Healthcare AI agents frequently have access to EHR systems (Epic, Cerner, MEDITECH), lab information systems, radiology PACS, and clinical data warehouses. Action-level gating is required to enforce the HIPAA Minimum Necessary Standard at the tool-use boundary.

Risk Profile

The highest-risk agent actions in healthcare environments include:

• File reads of PHI-containing records — access to patient demographics, diagnoses, lab results, imaging reports, or treatment plans without authorization
• Network requests to external endpoints — transmission of PHI outside the covered entity's approved data boundaries, violating HIPAA's transmission security requirements
• Database queries returning bulk patient data — agents running unbounded SELECT queries that return more PHI than necessary for the task
• File writes to clinical documentation — modification of clinical notes, discharge summaries, or medication orders without clinician review
• Shell execution of data export commands — running pg_dump, mysqldump, or ETL scripts that extract PHI into unencrypted files
• Access to authentication credentials — reading EHR API tokens, FHIR server credentials, or SSO certificates that grant access to entire patient populations

Regulatory Landscape

Healthcare AI agents must comply with the following regulatory frameworks:

HIPAA Privacy Rule (45 CFR 164.502) — Requires the Minimum Necessary Standard: covered entities must limit PHI access to the minimum necessary to accomplish the intended purpose. AI agents with broad tool access violate this standard unless action-level controls restrict access to only the PHI needed for each specific task.

HIPAA Security Rule (45 CFR 164.312) — Requires access controls (164.312(a)), audit controls (164.312(b)), integrity controls (164.312(c)), and transmission security (164.312(e)). AI agents are information systems under the Security Rule and must implement all four safeguards.

HITECH Act (2009) — Extends HIPAA enforcement to business associates and increases penalties. AI agent vendors and platforms that process PHI on behalf of covered entities are business associates requiring BAAs.

FDA Software as a Medical Device (SaMD) Guidance — AI agents that provide clinical decision support, assist in diagnosis, or influence treatment recommendations may be classified as SaMD under the FDA's Digital Health Precertification Program. These agents require documented risk controls and quality management systems.

21 CFR Part 11 — Electronic records and electronic signatures. AI agents that create, modify, or sign clinical documentation must comply with audit trail requirements (11.10(e)) and system validation requirements.

EU Medical Device Regulation (MDR 2017/745) — AI systems used in clinical settings within the EU may be classified as medical devices under Annex VIII classification rules. Requires conformity assessment, clinical evaluation, and post-market surveillance.

NIST Cybersecurity Framework (Healthcare Profile) — SP 800-66 maps HIPAA Security Rule requirements to NIST controls. AI agent access control maps to PR.AC (Access Control) and audit logging maps to DE.AE (Anomalies and Events).

Recommended Policy Template

# SafeClaw Policy — Healthcare / Clinical Data Environment
Deny-by-default. HIPAA Minimum Necessary enforced at action level.

rules:
  # DENY: Block all access to PHI directories
  - action: file_read
    target: "/patient-records/"
    decision: DENY
    reason: "PHI access blocked — HIPAA Minimum Necessary"

- action: file_read
    target: "/ehr-exports/"
    decision: DENY
    reason: "EHR export data blocked"

- action: file_write
    target: "/patient-records/"
    decision: DENY
    reason: "PHI modification blocked — requires clinician review"

# DENY: Block credential access
  - action: file_read
    target: "**/.env"
    decision: DENY
    reason: "EHR API credentials blocked"

- action: file_read
    target: "/credentials/"
    decision: DENY
    reason: "Credential store access blocked"

# DENY: Block bulk data export commands
  - action: shell_exec
    target: "pg_dump*"
    decision: DENY
    reason: "Bulk PHI export blocked — HIPAA breach risk"

- action: shell_exec
    target: "mysqldump*"
    decision: DENY
    reason: "Database dump blocked"

- action: shell_exec
    target: "rm -rf*"
    decision: DENY
    reason: "Destructive command blocked"

# DENY: Block network requests to unapproved endpoints
  - action: network
    target: "http://**"
    decision: DENY
    reason: "Unencrypted transmission blocked — HIPAA 164.312(e)"

# REQUIRE_APPROVAL: Clinical note modifications
  - action: file_write
    target: "/clinical-notes/"
    decision: REQUIRE_APPROVAL
    reason: "Clinical documentation changes require clinician sign-off"

# REQUIRE_APPROVAL: FHIR API calls
  - action: network
    target: "https://fhir..org/*"
    decision: REQUIRE_APPROVAL
    reason: "FHIR server access requires approval"

# ALLOW: Read approved de-identified datasets
  - action: file_read
    target: "/data/deidentified/**"
    decision: ALLOW

# ALLOW: Read application source code
  - action: file_read
    target: "/app/src/**"
    decision: ALLOW

# ALLOW: Run tests
  - action: shell_exec
    target: "npm test*"
    decision: ALLOW

# ALLOW: Access approved internal APIs over HTTPS
  - action: network
    target: "https://internal.hospital.org/api/**"
    decision: ALLOW

Example Scenarios

| # | Agent Action | Decision | Rationale |
|---|-------------|----------|-----------|
| 1 | Agent reads /data/deidentified/study-cohort.csv for research analysis | ALLOW | De-identified dataset in approved directory — no PHI |
| 2 | Agent attempts to read /ehr-exports/patient-12345.json | DENY | PHI file access blocked — HIPAA Minimum Necessary Standard |
| 3 | Agent writes updated clinical note to /clinical-notes/encounter-789.md | REQUIRE_APPROVAL | Clinical documentation modification requires clinician review before persistence |
| 4 | Agent runs pg_dump clinical_db > backup.sql | DENY | Bulk PHI export blocked — creates unencrypted copy of entire clinical database |
| 5 | Agent sends HTTP request to http://external-api.com/analyze | DENY | Unencrypted transmission blocked — HIPAA transmission security requires HTTPS |

Implementation Notes

SafeClaw enforces the HIPAA Minimum Necessary Standard at the action level. Every agent tool call is evaluated against the policy before execution. The deny-by-default architecture ensures that unrecognized actions — including novel attack vectors from prompt injection — are blocked without explicit rules.

The tamper-proof audit trail (SHA-256 hash chain) satisfies HIPAA Security Rule audit control requirements (45 CFR 164.312(b)). Every action attempt, decision, matched rule, agent identifier, and timestamp is recorded immutably. These logs can be exported from the browser dashboard for ingestion by healthcare SIEM platforms or provided to HHS OCR during compliance audits.

SafeClaw has zero third-party dependencies, which simplifies security review for healthcare IT teams evaluating supply chain risk. The client is 100% open source (MIT license) with 446 tests in TypeScript strict mode. The control plane receives only action metadata — never PHI, patient identifiers, or clinical data.
