About

Mysti is a beta VS Code extension that lets you send the same question to Claude Code and Codex for separate answers, or tag a specific agent for a task and hand completed work to another agent for review. It connects CLI agents, local model servers and the DeepMyst coordinator through 16 provider adapters, and keeps responses, context and permissions in one conversation. Apps and MCP servers can be connected through the Composio and Smithery catalogs that DeepMyst provides.

Use cases: coding, code-review, agent-orchestration
