osaurus vs grafbase
osaurus: Osaurus is an AI edge runtime for macOS, leveraging Apple Silicon for optimized local inference and connecting to various cloud models. It provides a native foundation for AI applications, exposing tools via the Model Context Protocol (MCP) and supporting custom assistants and automated workflows.; grafbase: Grafbase is a self-hosted, Rust-powered GraphQL Federation Gateway for high-scale, mission-critical applications. It unifies diverse data sources and microservices into a single, performant GraphQL API, offering enterprise-grade security and flexible deployment options.

When to choose:
- You want a high-performance Rust Apollo Federation v2 GraphQL gateway that can expose your federated graph directly as an MCP server.
- You want to unify GraphQL subgraphs, REST, gRPC, Postgres, and Kafka using WebAssembly extensions in a self-hosted gateway.
When to skip:
- You do not use GraphQL and just want a proxy/gateway in front of existing MCP servers; use MCP Gateways like AgentGateway or MetaMCP.
- You want to write custom MCP tools in Python; use FastMCP or the MCP Python SDK.
