From setup to publishing in minutes

Three simple steps to enable AI agents to publish files to your storage buckets.

Connect

Deploy Herald on Vercel and connect your Neon database. Configure your storage bucket in the admin panel.

Authorize

Grant users access to specific buckets with fine-grained permissions: read, write, or delete.

3

Publish

AI agents can now publish files directly using MCP tools. Every upload is logged for audit.

Enterprise-grade security

Security built in, not bolted on

Your data is protected by multiple layers of security. OAuth 2.1 with PKCE, JWT tokens, and complete tenant isolation.

OAuth 2.1 + PKCE

Industry-standard authentication with mandatory PKCE for enhanced security.

JWT Access Tokens

Short-lived JWT tokens with HS256 signing. Refresh token rotation for long sessions.

Per-User Access

Fine-grained permissions per user with optional prefix restrictions.

Multi-Tenant

Complete tenant isolation. Each organization has its own users, buckets, and data.

Audit Logging

Every upload logged with user, timestamp, file details, and metadata.

File Validation

Content type detection, size limits, and path traversal protection.
