 ## MCP setup notes
 
+The core bootstrap is client-neutral by default. It **does not write** `~/.claude/mcp.json` or `~/.codex/config.toml` unless an MCP host is explicitly selected. For MCP capabilities, use one of:
+
+```bash
+--mcp-host=claude
+--mcp-host=codex
+--mcp-host=both
+```
+
+Without an explicit host, the bootstrap may prepare the runtime but reports the MCP capability as `registration-required`. Override the explicit adapter paths with `CLAUDE_MCP_CONFIG` or `CODEX_CONFIG_PATH` when needed.

 - GUI app paths vary by edition and version. Do not hard-code IDA or Burp paths unless you verified them locally.
 - Some security tools are Linux-first. Prefer Homebrew formulae first, then GitHub releases, then source builds.
