Native Fastapi Dependency Injection And Middleware Preservation

Expose your FastAPI endpoints as Model Context Protocol (MCP) tools, with Auth!

Unique: Reconstructs the full FastAPI request context including dependency injection and middleware execution by using ASGI transport, enabling MCP-invoked endpoints to behave identically to HTTP-invoked endpoints. Most MCP-to-REST bridges bypass middleware and dependencies.

vs others: Preserves FastAPI's full execution context including dependencies and middleware, whereas HTTP-based MCP servers cannot access or execute FastAPI-specific features.

Create web-based user interfaces with Python. The nice way.

Unique: Directly exposes FastAPI's middleware and dependency injection system, allowing developers to reuse existing FastAPI authentication patterns without learning a new abstraction. User context is automatically available in NiceGUI event handlers.

vs others: More flexible than Streamlit's built-in auth; comparable to Dash's authentication but with FastAPI's mature ecosystem; simpler than building custom middleware.
