This extends [Activity MCP](activity-mcp-design.md). + +## Intended behavior + +The owner asks ChatGPT in a supported Work chat or dots to monitor selected +Beeper conversations. ChatGPT creates an MCP Events subscription on the existing +private `/mcp` endpoint. A resident UM790-Pro worker watches those conversations +through the existing headless Beeper Server/CLI. It persists new incoming message +identities and matching webhook deliveries before advancing its checkpoint. +ChatGPT receives the event, reads conversation context and existing activities, +and uses `publish_activities` to create or update concrete task/reply proposals. +No message sending or automatic completion is added. + +The monitored conversations are explicit subscription filters. Merely connecting +the plugin does not start monitoring all chats. Initial history supplies context, +not a backlog of new-message triggers. Beeper edits, reactions, outgoing messages, +and redelivery of the same message must not become new incoming events. + +## Responsibilities + +- Beeper CLI handles existing local authentication and fixed read-only API/watch + operations. Arbitrary commands, paths, and remote targets are not agent inputs. +- The resident worker handles WebSocket reconnects, periodic HTTP reconciliation, + durable checkpoints, message deduplication, and queued webhook delivery. +- MCP exposes chat discovery/context, event discovery/subscriptions, and the + existing activity read/publish tools. Research turn registrations stay separate. +- ChatGPT performs interpretation under the owner's monitoring instructions. + Message bodies and event excerpts are untrusted evidence, not instructions. +- SQLite remains the source of truth for activities and user decisions. + +## Delivery contract + +Event name: `beeper.message.received`. Filters select specific chat IDs. +Subscription identities are deterministic from the single workspace owner, +callback URL, event name, and normalized arguments. Subscriptions survive process +restarts, expire unless refreshed, and stop when unsubscribed. There is no +protocol cursor replay in the initial version. + +A verified HTTPS callback receives one signed event per request. Event IDs remain +stable across retries. Callback verification and delivery validate resolved +public destinations, pin the connection address, and reject redirects. Secrets +are encrypted with the app's existing credential key and never logged. +Transient failures have bounded retries; terminal failures remain inspectable +without logging conversation text. Unsubscribing removes pending deliveries. + +Authentication remains the explicitly selected single-owner private-tunnel +prototype. The application does not claim that it can distinguish individual +remote users: all callers inside that boundary represent the workspace owner. +Do not expose `/mcp` publicly or reuse this ownership model for multiple users. + +## Acceptance evidence + +- Real headless Server/CLI discovery and bounded read/watch handshake on UM790-Pro. +- Tests for baseline suppression, incoming-only selection, duplicate/edit handling, + disconnect reconciliation, and atomic checkpoint/outbox updates. +- Tests for subscription refresh/expiry/unsubscribe, callback verification, + signature validation, retries, and private-address rejection. +- Tests through the real MCP 2.0 HTTP endpoint for event discovery and lifecycle. +- A production plugin rescan discovers events and read tools. +- ChatGPT subscribes to an owner-selected conversation; an actual new incoming + message causes the configured task to run and publishes a source-backed + activity visible in Home/Messages. This last step is not proven by local tests. + +References: [OpenAI MCP Events](https://developers.openai.com/plugins/build/mcp-events), +[Beeper WebSocket](https://developers.beeper.com/desktop-api/websocket-experimental/). + +## UM790-Pro operation + +The app and `twitter-lite-events.service` use the same SQLite database and +credential key.

No GUI application or extra inbound listener is required. + +Configuration: + +- `TWITTER_LITE_DB_PATH`: absolute shared SQLite path. +- `TWITTER_LITE_CREDENTIAL_KEY_FILE`: existing private credential encryption key. +- `TWITTER_LITE_BEEPER_CLI`: absolute path to `beeper-cli`. +- `TWITTER_LITE_BEEPER_TARGET`: existing authenticated target (`um790`). + +The worker checks subscriptions every five seconds and reconciles at least once +a minute. WebSocket notifications request an earlier reconciliation. It scans +backwards using opaque `before` cursors to a saved message ID, persists progress +in batches of at most twenty pages, and resumes after restart. A first scan may +read older history but only messages timestamped at or after subscription start +are eligible for notification. A first-seen incoming message may already have +been edited; deduplication is by message identity, not edited status. + +Use these commands for operator status; logs contain counts/errors, not bodies: + +```sh +systemctl --user status twitter-lite-events.service +journalctl --user -u twitter-lite-events.service --since '10 minutes ago' +``` + +Do not run `beeper-cli status --json` into logs: it can expose stored credentials. +Use fixed read-only API commands and parse only required fields. + +## Connect a ChatGPT monitor + +1.
