What issue are you seeing?

Codex CLI 0.117.0 is detecting a local MCP server but caching it as having no tools.

Environment

• Codex version: 0.117.0
• Project: Laravel app with laravel/boost and laravel/mcp
• MCP server configured in ~/.codex/config.toml as:

[mcp_servers.laravel-boost]
command = "/opt/homebrew/bin/php"
args = ["artisan", "boost:mcp"]
cwd = "/Users/xxxx/src/webstack/cwics"

Observed behavior

• Codex UI shows laravel-boost with Tools: (none)
• Codex cache file ~/.codex/cache/codex_apps_tools/24f8a4dbd35e158afc9278429be4f359a5d156f9.json contains:

{"schema_version":1,"tools":[]}

Important evidence

• Codex startup log shows MCP is enabled:

session_init.enabled_mcp_server_count=2

• The Laravel Boost MCP server works correctly when tested directly over stdio.
• Running an initialize followed by tools/list against php artisan boost:mcp returns a populated tool list with 15 tools, including:

application-info, database-schema, search-docs, tinker, etc.

Direct repro command
cat <<'EOF' | /opt/homebrew/bin/php artisan boost:mcp
{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"debug","version":"1.0"}}}
{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}
EOF

Expected

• Codex should show the Laravel Boost tools and cache them correctly.

Actual

• Codex recognizes the MCP server exists, but caches the tool list as empty and the UI shows Tools: (none).

What steps can reproduce the bug?

Uploaded thread: 019d43c2-5940-79d3-b4e9-d83d964e519a

What is the expected behavior?

It should have been able to enumerate and cache the tools for the mcp properly, but it persists tools: [].
