🛠️ Tool
===================
Opening: Wardgate is a security gateway designed to sit between AI agents and external services. Its stated purpose is to prevent AI agents from directly receiving API keys, OAuth tokens, or other credentials while enabling controlled programmatic access to user resources.
Key Features:
• Credential isolation: Agents interact with Wardgate rather than external APIs, ensuring credentials remain within the gateway boundary.
• Access control: Policy-driven permissions per agent (examples: read-only calendar access, deny email deletion, require consent before sending messages).
• Sensitive-data filtering: Automatic blocking or redaction of one-time passwords (OTPs), verification links, and API keys in outgoing responses.
• Protocol adapters: Built-in passthrough for HTTP/REST and REST wrappers for IMAP and SMTP to support email workflows without exposing raw credentials.
• Audit logging: Metadata-only request logs to record agent actions without storing full content payloads.
• Approval workflows & anomaly detection: Human approval gates for sensitive operations and alerts on unusual agent behavior (e.g., bulk fetching mail).
Technical Implementation:
Wardgate is implemented as a proxy service with protocol adapter layers. The architecture divides responsibilities: an adapter layer translates agent HTTP requests into service-specific API calls (IMAP/SMTP wrappers for email), a policy engine enforces per-agent permissions, a filtering module inspects and redacts sensitive tokens from responses, and an audit subsystem records metadata-level events. The project is authored in Go and references Go 1.22 compatibility and an AGPL-3.0 license.
Use Cases:
• Integrating third-party AI agent frameworks such as AutoGPT or OpenClaw without sharing credentials.
• Delegating calendar and email automation while requiring human approval for destructive actions.
• Enterprise scenarios where auditability and least-privilege access must be enforced on agent behaviors.
Limitations:
Wardgate provides a security boundary but does not eliminate all risk. Policies must be carefully defined to avoid overprivileging agents. Filtering and logging choices reflect a trade-off between observability and privacy; the current logging design emphasizes metadata-only records, which may limit forensic detail for some incidents.
