Launch Week 1 — five features, five days

Jun 17, 2026 · Kenji Sakuramoto

Correction, 2026-09-21. The five features below shipped. The public posts this article promised (Show HN, Product Hunt, Reddit, a Friday retro) never went out, and the GitHub OAuth provider stayed switched off in production until September. The post is kept as written; the current launch plan and its gate are on the launch page, and the numbers are in 9 signups in 5 months. Correction, 2026-10-29: the Friday item named mushimushi.dev, a domain this project never owned. mushi login opens the console at kensaur.us/mushi-mushi/admin and you approve a code there; no key paste.

Mushi Mushi has been shipping quietly for a year. This week we stop doing that.

Five real features, five days, all announced publicly. The model is Supabase’s Launch Week — not a PR stunt, just a concentrated shipping cadence with enough momentum for the GitHub Trending algorithm to notice.

The five

Monday — open-source relicense. The server goes from BSL “source-available” to true OSI open source under AGPLv3. Read the post →

Tuesday — One-click MCP install. mushi setup writes .cursor/mcp.json (or .claude/, .continue/, or Zed’s settings.json) in one command. No UUID paste.


mushi setup               # wires Cursor by default
mushi setup --ide claude  # wires Claude Code
mushi setup --ide zed     # wires Zed

Wednesday — Zero-config SDK init. <MushiProvider> needs no props if NEXT_PUBLIC_MUSHI_* (or VITE_MUSHI_*, EXPO_PUBLIC_MUSHI_*, etc.) are in your .env. The snippet in the wizard now reads exactly what was written to the file.


// Before: <MushiProvider config={{ projectId: '...', apiKey: '...' }}>
// After:  <MushiProvider>  ← reads from env automatically

Thursday — GitHub OAuth + onboarding. Signup with one GitHub click. New users land on /onboarding instead of an empty dashboard. Self-hosters get MUSHI_INIT_* env vars for headless bootstrapping.

Friday — mushi login. The CLI now opens the console in your browser, waits for you to approve the sign-in there, and verifies it. No more copying Project UUIDs from the dashboard.


mushi login   # opens browser → approve → verified

Why now

The install path had two activation-blocking bugs:

The “Add to Cursor” button on /connect was 404ing against a non-existent endpoint.
The CLI wizard’s printed snippet used hardcoded literal keys instead of process.env.* — paste it and it broke.

Both are fixed. Launch Week is the announcement.

Numbers on Friday

Friday’s retro post will include: GitHub stars gained during the week, new signups, reports captured, and one honest “this didn’t go as planned” item. No rounding. No “we’re thrilled with the response.”
