Add MCP Server

Manage and configure your MCP servers in one centralized location. See Build Your Own MCP Server to build your own MCP server from scratch.

• Centralize your MCP server list to avoid re-entering server details for each workflow.
• Authenticate using OAuth mode with the authorization-code flow and a consistent callback URL.
• Use Auth Request mode to authenticate with a username and password against a token endpoint, storing the resulting access token.

Note: Tokens refresh automatically after OAuth or Auth Request authentication.
