Provider Based Resource And Tool Composition With Aggregation

via “provider-based resource and tool composition with aggregation”

🚀 The fast, Pythonic way to build MCP servers and clients.

Unique: Implements a composable provider system where each provider (filesystem, OpenAPI, FastMCP) is a self-contained capability source that can be mounted into a server independently. The AggregateProvider merges multiple providers into a single namespace, enabling modular architecture where tools and resources are organized by concern rather than monolithic server definitions.

vs others: More modular than monolithic server definitions because providers are independently testable and reusable; more flexible than hardcoded tool lists because providers can be dynamically selected at configuration time.
