agent-bridge vs Sephera

agent-bridge: AgentBridge uses a two-process architecture with a foreground MCP client (bridge.ts) and a persistent background daemon (daemon.ts). It enables bidirectional communication between Claude Code and Codex via a control WebSocket and proxy, with automatic reconnection and message loop prevention.; 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.
