mcp-webmvc-server

A Spring Boot sample MCP server that exposes weather-related tools (forecast by lat/long and alerts by US state) via the Spring AI MCP Server WebMVC transport. It can run over HTTP SSE (default) or over STDIO for MCP clients.

Secret Handling

README does not describe authentication/authorization or rate limiting for the MCP server. TLS requirements are not discussed; if deployed behind HTTPS, TLS would be handled by the hosting layer. The project likely makes outbound calls to weather.gov (per description), but handling of API keys/secrets and safe logging is not evidenced in the provided content.

Best When

You want a working reference implementation for an MCP server using Spring AI with either SSE or STDIO transport to expose typed tool callbacks.

Avoid When

You need explicit authentication, fine-grained authorization, and documented rate limits out of the box, or you require an API spec such as OpenAPI for direct REST consumption.

Use Cases

• Providing MCP tools for weather retrieval in an agent workflow
• Demonstrating Spring AI MCP Server Boot Starter integration with WebMVC transport
• Testing MCP client integrations using SSE or STDIO transports
• Building a template for exposing domain APIs as MCP tools

Not For

• Production deployments without further hardening (auth, rate limiting, error modeling, input validation, observability)
• Use as a complete/finished weather data service (it is described as a sample and weather implementation details are not provided here)
• Use cases requiring strong contractual REST-style APIs beyond the MCP protocol

Known Gotchas

⚠ Server runs in two modes (SSE default vs STDIO via JVM properties); clients must match the transport configuration.
⚠ The README indicates a configurable SSE message endpoint (/mcp/message), so routing/endpoint assumptions may differ by configuration.
⚠ No explicit guidance is given for tool-level validation errors or how structured MCP errors are returned.

Alternatives

Use a different MCP server implementation framework (e.g., another MCP SDK/library) with documented auth and operational controls Build a REST API + separate tool adapter (bridge) rather than exposing MCP directly Use Spring AI client/server boot starters and expand from a template with production-grade configuration
