Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
karellen-lsp-mcp
LSP-backed code intelligence for Claude Code via MCP and native LSP. Navigate definitions, references, call hierarchies, type hierarchies, hover documentation, symbols, and diagnostics across C/C++ (clangd), Java/Kotlin (jdtls), and any language with a custom LSP server. Two interfaces, one shared daemon: - **Native LSP proxy** (`karellen-lsp`): Transparent code intelligence — no permission prompts, no manual registration. Auto-detects languages and routes to backend LSP servers. - **MCP interface** (`karellen-lsp-mcp`): Explicit tool calls with structured responses for fine-grained control. Multiple Claude sessions share a single daemon and single LSP server per project, avoiding duplicate indexing. Supports autodetection of CMake, Meson, Gradle, Maven, and other build systems.
