langfuse-mcp vs Sephera

langfuse-mcp: Langfuse MCP Server is a Model Context Protocol server for Langfuse observability. It provides 37 tools across 9 categories including traces, observations, sessions, exceptions, prompts, datasets, annotation queues, scores, and schema. It supports selective tool loading and read-only mode, and can be used with various MCP clients like Claude Code, Cursor, and Codex CLI.; Sephera: Sephera is a local-first Rust CLI that combines repository metrics and deterministic context export. It provides fast line counting, deterministic context bundles with AST compression, and a built-in MCP server for AI agent integration. It focuses on giving reliable structural signals and focused context for LLMs and humans.
