It seems this is a bit like "reinventing permissions" no?

Could work - but our agents (codex/claude/openclaw) spawn subprocesses - imagine an engineer uses claude to debug an issue, it spawns psql directly, routing around MCP. Wire level interception is the only place a process tree can't escape.
Regarding reinventing permissions - scoped credentials solve this to some extent, but it's really nice to have a single place where we can define rules for all services (eg "DROP TABLE" never can occur), or you can SELECT unless it includes the env_vars.secrets column.
