Request Filtering And Validation With Custom Middleware And Decorators

☁️ Build multimodal AI applications with cloud-native stack

Unique: Provides composable request filtering via decorators and middleware with built-in patterns for authentication and rate limiting, enabling declarative input validation without custom executor code — unlike frameworks that require manual validation in handler functions

vs others: More integrated than FastAPI middleware (Jina-aware validation) and simpler than API gateway solutions (no separate infrastructure), while providing automatic filtering that manual validation requires explicit code for

via “request and response filtering with middleware pattern”

[Go MCP SDK](https://github.com/modelcontextprotocol/go-sdk)

Unique: Implements a composable filter chain at the protocol level, allowing cross-cutting concerns like logging and validation to be added without modifying handler code. Supports both synchronous and asynchronous filters with early termination.

vs others: More flexible than handler-level validation, with filters applying uniformly across all capabilities without code duplication.
