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.

  1. 1
    Start with an idea

    Test your own, or ask Rapidly to generate one or more ideas for a company using its website.

  2. 2
    Work through the method

    Rapidly builds the Lean Canvas, turns the riskiest assumption into a measurable hypothesis, researches a pass mark and designs practical experiments.

  3. 3
    Build only the test

    Rapidly gives your agent a build prompt for the smallest useful experiment. Your agent builds it. Real customers give you the evidence.

Works with Claude, Codex, ChatGPT and Hermes. OpenClaw, Grokbot and other agents can also use Rapidly if they support remote MCP. Your work is saved to your Rapidly team.

Start the connection before creating your token. That way the terminal is ready when the token appears.

Using Codex CLI or Claude Code? Copy the setup, paste it into a fresh terminal and press Enter. Leave the terminal waiting for your token.

Show the setup commands

Codex CLI

printf 'Paste your Rapidly token, then press Enter: '; IFS= read -rs RAPIDLY_MCP_TOKEN </dev/tty; printf '\n'; export RAPIDLY_MCP_TOKEN; codex mcp add rapidly --url https://www.rapidly.co/mcp/ --bearer-token-env-var RAPIDLY_MCP_TOKEN && codex

Claude Code

printf 'Paste your Rapidly token, then press Enter: '; IFS= read -rs RAPIDLY_MCP_TOKEN </dev/tty; printf '\n'; export RAPIDLY_MCP_TOKEN; claude mcp add --transport http --scope user rapidly https://www.rapidly.co/mcp/ --header 'Authorization: Bearer ${RAPIDLY_MCP_TOKEN}' && claude

These copy-ready setups work in Bash or Zsh on macOS and Linux. On Windows, set an environment variable named RAPIDLY_MCP_TOKEN, then add this page’s MCP server address as a bearer-authenticated HTTP server.

Using another agent? Add Rapidly as a remote MCP server https://www.rapidly.co/mcp/

Keep this page open. Create your token only after the terminal or agent is ready for it.

2. Create your token

Enter your name, email and team name. We’ll create your account and team, then show the token once. No plan or password needed.
