HealthClawGuardrails vs helio

HealthClawGuardrails: HealthClaw Guardrails is an open-source, vendor-neutral security layer designed to sit between any AI agent and any FHIR server, providing critical safeguards for clinical data interaction. It enforces PHI redaction, maintains an immutable audit trail, implements step-up authorization, and enables human-in-the-loop validation for sensitive operations.; helio: Helio is an open-source MCP proxy that provides governance for AI agents by enforcing policies on tool calls, managing spend, and routing approvals. It operates between agents and their tools, ensuring useful autonomy without unlimited authority across various platforms and frameworks.

Features

HealthClawGuardrails logoHealthClawGuardrails
01PHI Redaction: Automatically truncates names, masks identifiers, strips addresses, and truncates birth dates to year for privacy.
02Immutable Audit Trail: Logs every read and write operation with tenant, agent, and timestamp for compliance and accountability.
03Step-up Authorization: Requires HMAC-SHA256 tokens for write operations, enhancing data integrity.
04Human-in-the-loop: Blocks clinical writes until a human confirms the action, preventing unintended consequences.
05Tenant Isolation: Scopes every query to the specific tenant and blocks cross-tenant data access.
helio logohelio
01Declarative Policy Engine: Define YAML rules for tool names, inputs, and state, with hot-reloading and dry-run mode.
02Cross-Tool Spend Budgets: Aggregate and cap spending across multiple tools and MCP servers with break-glass approvals.
03Approval Workflows: Route sensitive tool calls to Slack, webhooks, or the dashboard for human review and approval.
04Comprehensive Audit Trail: Record all tool calls, policy decisions, and responses for full traceability and searchability.
05Evidence Grounding: Require fresh, application-provided evidence to validate actions, preventing accidental skips.
