What is OpenNomos
A growth capability layer for your own agent, with project memory that outlives any one session.
OpenNomos is not an agent. It is a layer your own agent (Claude Code, Cursor, Codex, or any MCP client) connects to, so that agent can do growth work without you wiring up a dozen scrapers and APIs, and without forgetting everything when the session ends.
It gives the agent two things:
- Capabilities. Tools that read public sources and return the data: conversations on the web, Reddit, X, Xiaohongshu, Zhihu and Weibo, SEO and keyword data, what ChatGPT answers about your category, app reviews and video comments, creator profiles, competitor tech stacks and ads, news and trending lists, and any page as clean markdown. Results are returned to the agent. They are never saved on their own.
- Project memory. A server-side record, per project, that the agent writes explicitly: free-form notes (decisions, rules, drafts, conclusions), plus an optional follow-up state for the people and posts worth acting on (opportunities), small experiments with a deadline, short links, and the actions you took.
Quickstart
Connect over MCP, authorize, and verify with discover_tools.
Core concepts
Project, memory, opportunity, experiment, action and briefing in one page.
The growth loop
Pull a briefing, work, write back with track and log_action.
Tools reference
All 21 tools: parameters, examples, errors and cost.
What OpenNomos deliberately does not do
- It does not post, reply or message anyone. Your agent or you act elsewhere, then record it. The tools only record.
- It does not decide. No fixed workflow, scoring of your ideas, categories or required order. The growth tools are optional and can be used one at a time.
- It does not infer. Stages are never guessed from actions, and results with no known source are counted as
unknown, not credited to a channel. - It does not save by itself. Memory is written only when the agent asks.
