Hypotize for Hermes Agent
Turn Hermes into a disciplined growth hacker. This plugin connects Hermes Agent to Hypotize, the agent-native Growth OS for growth, product and marketing teams.
With Hypotize connected, Hermes reads what the team already tested before proposing anything new. It writes hypothesis-first ideas, scores them with ICE, PIE, RICE or your own framework, moves experiments through an enforced lifecycle (Idea, Approved, Ready, Running, Analyzing, then a measured outcome) and records the result and the learning. The next conversation starts from what you already know.
Hypotize does not run A/B tests or assign traffic. Keep your analytics and experimentation tools: Hypotize keeps the record before and after an experiment runs.
What is inside
- MCP server: the hosted Hypotize server at
https://api.hypotize.ai/mcp, OAuth 2.1. You sign in to Hypotize in the browser when Hermes connects. - Skills:
hypotize-growth-experiments: the method. Read before proposing, vote with evidence, follow the lifecycle, close with a measured result.hypotize-weekly-review: a read-only pipeline review that ends with what needs a decision.hypotize-backlog-import: move a spreadsheet or Notion backlog into Hypotize, in atomic batches of 50.
Install in Hermes Agent
hermes plugins install hypotize
Requires Node.js 20.18.1 or newer with npm, because sign-in runs through mcp-remote. When Hermes calls a Hypotize tool and you are not signed in yet, a browser window opens: sign in with Google or email and approve access. If Hermes stops waiting before you finish signing in, run /reload-mcp and complete the sign-in in the new browser window. Then ask Hermes, for example: "Read my Hypotize backlog and tell me which idea to test next."
You need a Hypotize account. The free plan works: sign up.
What the plugin does on your machine
- Network calls: every tool call goes to Hypotize's hosted server (
api.hypotize.ai) and acts on your Hypotize account with your role in each project. The tool set is served by that server at runtime and is not part of the pinned commit. - Sign-in: Hermes starts the pinned
mcp-remote@0.1.49throughnpx. Until you sign in, it opens a browser and a local callback port, then stores OAuth tokens under~/.mcp-auth. Run it once in an interactive session: an unattended run (cron, the messaging gateway) cannot complete the browser sign-in. - Approvals: the package marks the server
untrusted, so Hermes asks before every tool the server does not mark read-only and refuses them in unattended runs. Delete access is off unless you grant it when you sign in. - No telemetry in the plugin. Hypotize stores the experiments, votes, comments and learnings you or Hermes write, under the privacy policy.
