Install and sign in

In /plugin, install merv from rapidreview. Then select Connect for Merv in Customize. Team marketplaces can enable Auto Refresh.
Ask the agent to call project(action="list"), then workflow.status_and_next(project_id). Follow along in the web UI at rapidreview.io/merv.
Sign-in is UI-only: Customize → Connect. There is no CLI sign-in command. Cursor has no non-interactive plugin install and no documented auto-update guarantee for an individual custom marketplace. Teams/Enterprise: import as a team marketplace and enable Auto Refresh.

​
Skills and reviewers

Skills follow the Agent Skills standard and are auto-discovered; reviewer agents too. Delegate a review with /experiment-design-review or in natural language — subagents get a clean context window. See Reviewer handoff.

​
Long runs

Cursor 3.0+: a background shell with notify-on-output armed on the sentinel regex ^MERV_RUNS_WAIT . Shell exit or a matched line resumes the agent. If a long-idle reattach fails, re-run the watcher or use a stop-hook loop. See Long runs.

​
Caveats

  • Cursor caps around 40 tools across all active MCP servers. Merv exposes 41 by default, so Merv alone can hit the cap; turning Storage off for the project drops six, and disabling other servers helps.
  • Cursor may show a naming warning for dotted tools such as workflow.status_and_next; calls still work.
  • Local dev bundles must be copied, not symlinked — Cursor rejects symlinks whose target is outside ~/.cursor/plugins/local. From the repo root: python3 merv/scripts/build_client_bundle.py --out ~/.cursor/plugins/local/merv.
