Contextcore vs gomcp
Contextcore: ContextCore is a local-first MCP server that indexes your local files (text, code, images, audio, video) and provides hybrid search (BM25 + embeddings) via a single MCP server. It reduces token usage by 57% compared to pasting entire files. It works with Claude Desktop, Claude Code, Cursor, Cline, and any MCP-compatible tool.; 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.
