Codex

Same server, no plugin wrapper: point Codex's MCP config at it directly. Add this to your Codex config (~/.codex/config.toml):

[mcp_servers.syntica]
  command = "npx"
  args = ["-y", "@syntica/mcp"]

Restart Codex to pick it up. All 59 tools are available the same way. You just ask for what you need in your own words instead of running a slash command, since Codex doesn't have the Claude Code-specific command layer.
