Description

When running vendor/bin/sail artisan boost:install and selecting Codex, the generated .codex/config.toml contains cwd = "/var/www/html" — the path inside the Docker container, not the host filesystem.

Codex CLI runs on the host machine, so it tries to chdir to /var/www/html, which doesn't exist, and the MCP server fails to start:

⚠ MCP client for `laravel-boost` failed to start: MCP startup failed: No such file or directory (os error 2)
⚠ MCP startup incomplete (failed: laravel-boost)

Root cause: Codex::mcpServerConfig() sets cwd to config('boost.executable_paths.current_directory', base_path()). When the Artisan command runs inside Sail, base_path() returns /var/www/html, which gets written verbatim into the host-side TOML config.

The base Agent::mcpServerConfig() does not include cwd, so Claude Code's .mcp.json is unaffected — vendor/bin/sail resolves correctly from the project root.

Workaround: Remove the cwd line from .codex/config.toml after installation.

Steps To Reproduce

1. Install Laravel with Sail
2. composer require laravel/boost
3. vendor/bin/sail artisan boost:install — select Codex with MCP enabled
4. Inspect .codex/config.toml — observe cwd = "/var/www/html"
5. Run codex from the project root — MCP fails with "No such file or directory"
6. Remove the cwd line — MCP starts successfully
