 ## MCP Servers
 
-Treat the project-local `.codex/config.toml` as the default Codex baseline for ECC. The current ECC baseline enables GitHub, Context7, Exa, Memory, Playwright, and Sequential Thinking; add heavier extras in `~/.codex/config.toml` only when a task actually needs them.
+Configure in `~/.codex/config.toml` under `[mcp_servers]`. See `.codex/config.toml` for reference configuration with GitHub, Context7, Memory, and Sequential Thinking servers.
