Rapidly MCP¶
Test the idea before you build it. Rapidly works inside your AI agent: in about five minutes it takes an idea through a Lean Canvas, turns the riskiest assumption into a measurable hypothesis with a researched pass mark, and returns a build prompt for the smallest Pretotyping experiment worth running. The agent builds the test; real customers provide the evidence. Work is saved to your Rapidly team instead of disappearing in a chat thread.

Why This Matters for Operators¶
Asking a general model for a business plan produces something that looks reasonable and proves nothing. Rapidly encodes the method instead: Alberto Savoia's Pretotyping combined with the vendor's practice across 4,000+ client experiments and 200+ workshops. The core run builds a full Lean Canvas, converts the riskiest demand assumption into a market-engagement hypothesis with a researched pass threshold, then designs three to five named experiments and recommends the smallest useful one with a build prompt. The output includes GO/NO-GO rules, cited sources, and a test asset your agent can build immediately.

validate_idea |
Produces a quick Canvas, hypotheses, and a suggested first experiment without public-source grounding |
Installation¶
Open rapidly.co/rapidly-mcp, enter a name, email, and team name. Rapidly creates the account and team, then shows the personal token once (no plan or password needed). The page provides copy-ready setup for Codex CLI and Claude Code.
Configuration¶
- New teams: keep the bearer token in the RAPIDLY_MCP_TOKEN environment variable and register the endpoint https://www.rapidly.co/mcp with that header.
- Existing teams: connect with OAuth, choose the team, and approve access.
- Works with Claude, Codex, ChatGPT, and Hermes; any agent that supports remote MCP can connect.
- Rapidly checks team and access scoping on every request.
Business Relevance¶
- Pre-build validation: a build prompt for the smallest experiment instead of a full product commitment.
- Evidence-based decisions: GO/NO-GO rules and pass thresholds reviewed by real customers.
- Portfolio discipline:
score_portfolioranks ideas by value and effort for funding conversations. - Institutional memory: experiments, outcomes, and lessons stay in the team workspace.
Integration with CorpusIQ¶
Rapidly's experiment evidence pairs with CorpusIQ connectors for the measurement side: validate demand with GA4 landing-page traffic, Shopify trial orders, or Stripe revenue during a Fake Door test, and log hypotheses and pass marks in Notion or Airtable so the validation record lives next to the operating data.
Limitations¶
- Free trial caps at five new ideas; team plans require contacting the vendor.
- Generated facts, cited sources, and proposed targets need human review before use.
- Bearer token is shown once at creation - store it securely.
- Young repo (created Aug 24, 2026, 1 star); anonymous endpoint probes return 401 (liveness verified).
