via “connection and authentication management with oauth and api key support”

AI Agents & MCPs & AI Workflow Automation • (~400 MCP servers for AI agents) • AI Automation / AI Agent with MCPs • AI Workflows & AI Agents • MCPs for AI Agents

Unique: Implements a piece-driven authentication model where each piece declares its auth requirements via a standardized interface, and the connection service automatically injects credentials at execution time. This decouples authentication logic from piece implementation and allows pieces to be reused across different authentication schemes. OAuth token refresh is handled asynchronously by the worker pool, preventing flow execution from blocking on token refresh.

vs others: More secure than Zapier for self-hosted deployments (credentials never leave the server) and simpler than n8n (centralized connection management vs per-node credential configuration)

via “three-tier role-based access control with session and api key authentication”
