Users who run MCP tools through a CLI wrapper (e.g. philschmid/mcp-cli)
instead of registering servers natively don't produce Codex
mcp_tool_call_end events; Codex logs a plain exec_command. So their MCP
usage showed only as a shell command and was absent from the MCP
breakdown, even after #513 fixed the native path.
- Recognize `mcp-cli [options] call <server> <tool>` in the exec command
and also attribute it as mcp__<server>__<tool>. The exec still counts as
Bash since it genuinely is a shell exec. Flag-tolerant, quote/path/bash-lc
tolerant, and scoped to the mcp-cli binary (not foo-mcp-cli); only the
`call` subcommand (a real execution) matches, not info/grep/listing.
- Register `codex` in PROVIDER_PARSE_VERSIONS. session-cache.json serves
unchanged session files without invoking the provider parser, so the
codex-cache version bump alone would never re-attribute already-cached
sessions. This also retroactively repairs #513's native-MCP fix for
users whose files were cached before it shipped.
- Bump CODEX_CACHE_VERSION 4->5 for the provider-internal layer.
Tested: parse cases (bash -lc wrapper, flags-before-call, argv array,
plus info/grep/foo-mcp-cli negatives), and a mutation-verified cache
regression test that fails without the PROVIDER_PARSE_VERSIONS entry.
ReDoS-checked. Reviewed with a Fable 5 adversarial pass (Codex is down);
its two must-fixes (the cache gap and the flags-before-call miss that
would have missed the reporter's own sessions) are folded in.
Fixes#478
