title: Barndoor Platform Agents Connections API
version: 1.0.0
description: 'REST API for the Barndoor Platform - manage MCP servers, OAuth connections, and proxy MCP requests.
## Authentication
All endpoints require a JWT Bearer token obtained through Auth0 OAuth 2.0 flow with PKCE.
The SDK handles the OAuth flow automatically using interactive login.
## MCP Integration
The `/mcp/{mcp_server_name}` endpoints provide streaming proxy access to third-party MCP servers
(Salesforce, Notion, Slack, etc.) with automatic authentication and session management.
