MCP DevBridge v0.8.6
MCP DevBridge v0.8.6 — Goal-like ChatGPT long-turn resilience
This release hardens long-running MCP work in ChatGPT without reintroducing the removed v0.9 multi-Agent runtime.
- Adds protocol-safe 12-second SSE idle keepalives at complete event boundaries only.
- Adds a bounded Streamable HTTP EventStore for retained-event replay with
Last-Event-ID. - Makes
wait_taskprogress-aware: 30-second cap without a progress token, up to 120 seconds with standard MCP progress notifications. - Compacts repeated running-task output to small UTF-8-safe tails and lengthens adaptive poll hints for long tasks.
- Strengthens model instructions so clear, actionable goals continue in the same assistant turn instead of asking the user to type “continue”.
- Preserves durable
long_run_*recovery for host-side hard disconnects such asMessage delivery timed out. - Adds cross-platform transport/replay/progress/fault-injection regressions and fixes the Linux install-script parser issue found by the stronger gate.
Validation
- Windows Python gate: 352 passed, 3 skipped; Ruff passed; Pyright 0 errors / 0 warnings.
- CodexPro TypeScript build and complete smoke suite passed.
