Convert MCPManager's dangling single-slot setOnNotification callback into
a multi-listener API and expose server-initiated MCP notifications as an
extension event so extensions can bridge push-capable MCP servers (e.g.
peer messaging, ticket nudges) into session behavior.
API changes:
- Removed: MCPManager.setOnNotification(handler) — single-slot, zero callers
- Added: MCPManager.addNotificationListener(listener): () => void
Multi-listener with per-listener error isolation, returns unsub.
- Added: 'mcp_notification' extension event
Payload: { server: string; method: string; params: unknown }
Wired in sdk.ts: one listener bridges to extensionRunner.emitMcpNotification,
captured under postmortem for teardown.
Tests: 3 new (multi-listener fanout, error isolation, unsubscribe),
fixture pattern matches neighboring mcp tests. bun check passes (biome +
tsgo).
Docs: extensions.md (new MCP notifications subsection with bridging
example), mcp-runtime-lifecycle.md (Server-initiated notifications
section), CHANGELOG.

Memory backends
The agent supports three mutually-exclusive memory backends, selected via the memory.backend setting (Settings → Memory tab, or ~/.omp/config.yml):
off(default) — no memory subsystem runs.local— existing rollout-summarisation pipeline; writesmemory_summary.mdand consolidated artifacts under the agent dir.hindsight— talks to a Hindsight server (Cloud or self-hosted Docker), retains transcripts every Nth user turn, recalls memories on the first turn of a session, and exposesretain,recall, andreflect.
Hindsight quickstart
- Run a Hindsight server (Cloud or
docker run -p 8888:8888 ghcr.io/vectorize-io/hindsight:latest). - Set
memory.backend = "hindsight"andhindsight.apiUrl = "http://localhost:8888"(or your Cloud URL). - Optional environment overrides (env wins over settings):
HINDSIGHT_API_URL,HINDSIGHT_API_TOKEN— connectionHINDSIGHT_BANK_ID,HINDSIGHT_DYNAMIC_BANK_ID,HINDSIGHT_AGENT_NAME— bank addressingHINDSIGHT_AUTO_RECALL,HINDSIGHT_AUTO_RETAIN,HINDSIGHT_RETAIN_MODE— lifecycleHINDSIGHT_RECALL_BUDGET,HINDSIGHT_RECALL_MAX_TOKENS— recall sizingHINDSIGHT_BANK_MISSION,HINDSIGHT_DEBUG
Switching backends mid-session immediately replaces the live backend, memory tools, listeners, and system-prompt context. Existing users with memories.enabled = true|false are migrated to memory.backend = "local"|"off" exactly once on first launch; afterward, memory.backend is the sole runtime selector.
