Sample Multi Tenant Saas

This repository contains a multi-tenant remote MCP server implementation using the Streamable HTTP transport written with the TypeScript SDK.

MCP Server

A remote MCP server implementation for B2B travel booking with multi-tenant authentication and authorization via Amazon Cognito and OAuth 2.1.

• Node.js with Express and MCP SDK for tools, resources and prompts
• AWS services: ECS, DynamoDB, S3, Cognito
• Protected Metadata Resource handling (RFC 9728)
• Multi-tenant architecture with data isolation
• Dynamic client registration (RFC 7591)
• OpenID Configuration endpoint to advertise the registration endpoint (RFC 8414)

For a detailed architecture overview, see the MCP Server README.

Deploy

cd mcp_server/infra
npm install
./deploy.sh

Note the output URL (https://mc-xxx.ecs.<region>.on.aws). Create a user with the manage-users script:

cd mcp_server/scripts
npm install
node manage-users.js create myuser [email protected]

The +tenantname suffix becomes the tenant ID (see User Management).

Try it

Two ways to connect to the deployed server.

1. MCP Inspector

For protocol-level inspection — see tools/resources/prompts, invoke them manually, no LLM in the loop.

npx @modelcontextprotocol/inspector

Open the URL it prints, paste https://mc-xxx.ecs.<region>.on.aws/mcp, complete the OAuth flow, exercise tools.

2. Amazon Quick Suite

For end-to-end chat with the MCP tools. The Quick Suite MCP client handles OAuth 2.1 + PKCE + Dynamic Client Registration automatically.

1. Open Amazon Quick Suite → Connections → Integrations → Actions.
2. Choose Model Context Protocol → +.
3. MCP server endpoint: https://mc-xxx.ecs.<region>.on.aws/mcp
4. Authentication: User authentication (OAuth). Leave credentials blank — DCR will register Quick automatically.
5. Approve in the Cognito hosted UI when prompted.
6. Quick discovers all tools (whoami, find_flights, book_flight, list_hotels, book_hotel, list_bookings, loyalty_info).
