TinyScale

Small SaaS building blocks your coding agent can set up, verify, and hand to you.

Ask your agent to "add a launch waitlist" or "add a feedback widget and a changelog". It creates a TinyScale project with no account and no card, wires the embed into your app, proves it works with a real result, then opens a claim page so you keep it on the Free plan.

Use it from a coding agent (MCP)

Add the local MCP server to your agent. It runs in your project directory and keeps credentials in .tinyscale/ (git-ignored, never returned to the model).

Claude Code

claude mcp add tinyscale -- npx -y tinyscale mcp

Or install the plugin, which adds the MCP server plus a skill that teaches Claude the setup flow:

/plugin marketplace add sanv725/tinyscale-agent
/plugin install tinyscale@tinyscale

Cursor, Windsurf, VS Code, Codex and other MCP clients

{
  "mcpServers": {
    "tinyscale": { "command": "npx", "args": ["-y", "tinyscale", "mcp"] }
  }
}

Then ask: "Use TinyScale to add a launch waitlist to this app and verify it works."

Use it from the command line

Requires Node.js 20 or later.

npx tinyscale workspace discover                      # products and preview limits
npx tinyscale workspace create --name "My app" --products tinywaitlist,tinychangelog
npx tinyscale waitlist create --configuration-json '{...}'
npx tinyscale workspace claim                          # human claims the project, no payment
npx tinyscale --help

Each product has an exact agent guide: agent.md · waitlist · changelog · activate · import · demo · cite

How it works

1. Preview — the agent creates a project that lasts 72 hours. No sign-up, no card. Limits are small and hard-stop; nothing is charged.

2. Verify — the agent proves the integration with a real result: a feedback submission ID, a synthetic waitlist signup, a passing browser check with a receipt.

3. Claim — you open the claim page, sign in, and the same project, IDs and embeds continue on Free. Public-facing actions (accepting real emails, publishing release notes) need your approval.

Security

• Credentials live only in .tinyscale/agent-state.json (mode 0600, git-ignored). Tool results never include them or the claim link.

• The CLI only talks to https://api.tinyscale.io (plain HTTP only for localhost development).

• Widgets only run on exact HTTPS origins you configure; browser checks require proof you own the origin.
