MCP Examples

Learn how to build secure MCP servers with Descope through these step-by-step examples:

Calendar MCP Server

Calendar Management MCP Server (w/ SSO)

Build a secure calendar MCP server that:

• Restricts access to only registered MCP clients (Claude Desktop and ChatGPT)
• Requires SSO authentication via Okta or Azure AD for multiple tenants
• Grants write access only to users with specific permissions
• Allows read-only access to all other authenticated users

Multi-Tenant MCP Server

Multi-Tenant MCP Server

Run one MCP server for users across different tenants:

• One MCP URL and consent flow — users pick their tenant at sign-in via the tenant selector
• One scope per tool; access policies decide which tools each tenant's users get at consent
• The server stays tenant-agnostic — no tenant-to-tools map in code, and onboarding a new organization is a policy change, not a redeploy
• Tools read the active tenant from the token's dct claim; switching organizations means re-authenticating for a new token
