mcp 0.5.0 - can tools call other tools or is execution isolated per-call
deploying next week and need to know if tool A can invoke tool B within the same agent session, or if each tool call is completely isolated. documentation doesn't cover this at all and we need to know for our filesystem + database tool architecture. can a filesystem read tool trigger a postgres write tool in the same execution context?

need to know this too. tested in staging yesterday, couldn't tell if tool A can invoke tool B or if execution is isolated per-call

tools can call other tools in 0.5.0 but there's zero cycle detection.... we built a filesystem tool that calls a validation tool and it just loops forever if you're not careful. honestly the execution model is completely undocumented
