FirstData vs gomcp
FirstData: FirstData is the world's most comprehensive, authoritative, and structured open data source repository, designed with an Agent-First approach. It covers 1000+ authoritative data sources from governments, international organizations, and research institutions, providing structured metadata including access URLs, API endpoints, and authority levels. The project aims to build a trusted foundation for AI by ensuring every conclusion can be traced back to primary sources.; gomcp: GoMCP is a Go framework for building Model Context Protocol servers — described as "Gin for MCP." It provides struct-tag-based automatic JSON schema generation, a full middleware chain (logging, auth, rate limiting, OpenTelemetry), tool groups, and one-line imports for Gin routes, OpenAPI/Swagger specs, and gRPC services. Built-in Bearer/API Key/Basic auth with RBAC and an inspector UI included.
