grafbase vs mcp-fusion
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.; mcp-fusion: `mcp-fusion` is an advanced TypeScript framework designed to consolidate numerous Model Context Protocol (MCP) operations into a single, intelligent LLM tool. It addresses context exhaustion and routing confusion by utilizing build-time multiplexing and context gating for scalable, precise API interactions.
01
TL;DR
Choose grafbase if…Unifying disparate microservices, legacy systems, and third-party APIs into a single federated GraphQL API.
Choose mcp-fusion if…Consolidating numerous individual Model Context Protocol (MCP) tools into a single, unified LLM interface.

Features
grafbase01Native support for Apollo Federation v2 specification.
02Rust-powered gateway delivering ultra-low latency and memory efficiency.
03Extensible via WebAssembly for custom authentication, authorization, and data sources.
04Enterprise-grade security with advanced schema governance and fine-grained authorization.
05Universal data integration supporting GraphQL subgraphs, REST APIs, gRPC, and databases.
mcp-fusion01Build-Time Multiplexing & Context Gating: Consolidates related operations under a single tool, reducing LLM context pressure and routing hallucinations.
024-Tier Per-Field Annotation Intelligence: Automatically generates precise field requirement annotations (e.g., 'Always Required', 'Required-For') for the LLM.
03Zod Parameter Stripping & Type Safety: Merges and strips unknown parameters using Zod, ensuring security and type-safe handlers at runtime.
04Tag-Based Selective Tool Exposure: Controls which tools the LLM sees per session, optimizing token usage for 5,000+ endpoints.
05Pre-Compiled Middleware Chains: Executes global or group-scoped middleware at runtime with zero chain assembly or closure allocation per request.
