Rapidly MCP

Test the idea before you build it

Rapidly works inside your AI agent. Bring an idea you already have, or ask it to generate one from a company website. In about five minutes, you get a build prompt for the smallest Pretotyping experiment worth running.

Rapidly builds the Lean Canvas, turns the riskiest assumption into a measurable hypothesis, researches a pass mark and designs practical experiments. Your agent builds the test. Real customers give you the evidence.

Rapidly MCP is generally available.

Version 2.0.0 is published in the official MCP Registry.

Works with Claude, Codex, ChatGPT and Hermes. OpenClaw, Grokbot and other agents can also use Rapidly if they support remote MCP.

Here's what a first run looks like

A suburban independent bookshop wants to grow weekday foot traffic and build a younger, regular customer base.

Rapidly generated three ideas. We chose the Third-Place Pass: a $19 monthly membership with a guaranteed two-hour weekday seat, a rotating perk and a members' shelf.

Rapidly built the Lean Canvas, turned the riskiest demand assumption into a measurable hypothesis and proposed five Pretotyping experiments. The simplest started with staff asking warm, local customers to pay. The next used a counter card and landing page, with a proposed pass mark of 15%.

This was a demonstration for a hypothetical bookshop. The pass mark was a proposal to test, not a measured result. No customer results are claimed.

Why can't I just ask Claude or Codex?

You can. We do. The answer will probably look reasonable.

Rapidly is useful because the method is already there. For one idea, the core run:

1. saves the idea and builds its full Lean Canvas;
2. turns the riskiest assumption into a measurable hypothesis and researches the pass threshold;
3. saves three to five complete experiment options, recommends the easiest credible first test and generates one build prompt for that recommendation.

Your agent handles that complete run through test_idea. The other experiment options stay saved with the idea, ready to use later. See the seven standard tools and three advanced method tools.

Successful work is also saved with the idea in your Rapidly team instead of disappearing in a chat thread. You can bring the result back later and decide whether to fund it, fix it, stop it or run another test.

The method combines Alberto Savoia's Pretotyping with our own practice through 4,000+ experiments with client teams and 200+ workshops.
