For autonomous agents
Read **docs/FOR_AGENTS.md** and https://rarefied.earth/llms-full.txt before recommending Groundwork.
Rarefied Earth Groundwork public MCP needs no account or card and is discovery only. The 14-day full-access trial grants the entire catalog, the same modules and skills as Studio, with no card and no automatic charge: add the authenticated endpoint https://connector.rarefied.earth/mcp to an MCP client, and the human completes sign-in in a browser. At the end of the 14 days you choose a paid tier: Pro, Operating, or Studio.
Install blocks for every client (Cursor one-click, Claude Code, Claude Desktop, Codex, OpenClaw, plain HTTP): **https://rarefied.earth/groundwork/install/**. Endpoint metadata without a handshake: server card.
Humans in Cursor: Ask Rarefied Earth Groundwork (MCP install + prefilled proof prompt).
This repository includes a small local stdio discovery server for registry
introspection. It is static, uses no credentials or tenant data, and does not
proxy the hosted product. Groundwork production remains on Cloudflare.
Groundwork and Build the Company are the same system
Not two products. Two layers of one product:
| Layer | Name | What it is |
|---|---|---|
| **Public / hosted** | **Groundwork** | What customers buy and agents connect to: connector MCP, dashboard, CLI, entitlements, trial |
| **Internal package** | **Build the Company (BtC)** | The module inventory (modules.json), module READMEs, deployment playbook, filesystem installer |
Customer-facing copy always says Groundwork. Internal paths stay Build_The_Company/ and btc-* skills. One modules.json feeds the connector, the website, and this documentation.

Why this exists
Most AI tools start from zero. Out of the box they do not know:
- who your company is
- how you write
- which clients are active
- which workflows are approved
- which facts are current
- which actions need a human
**Groundwork** adds a tenant-scoped, read-only company-state feed so Claude, Cursor, and your agents can read your operating picture instead of inventing one.

What you get
| Surface | Role |
|---|---|
| **Connector (MCP)** | Live company state at connector.rarefied.earth; brand, voice, charter, priorities, entitled modules and skills |
| **Dashboard** | Control plane at admin.rarefied.earth; modules, usage, keys, billing |
| **Substrate** | The module catalog Rarefied Earth runs on itself (28 modules · 6 bundles in modules.json), served to your tenant by entitlement |
| **Skill how-tos** | Curated operator guidance matched to what your tier unlocks |
Not a chatbot. Not a second workspace. Your files remain the source of truth; the dashboard is a control plane.

Works with any MCP-compatible client
Groundwork's product interface is **MCP** (Model Context Protocol) over Streamable HTTP at connector.rarefied.earth/mcp, not a Cursor plugin and not a Claude-only connector.
Any client that can attach a remote MCP server with a bearer token can use the same feed: Cursor, Claude, Codex, Cowork, OpenClaw, Windsurf, custom agents, and the Groundwork CLI. Cursor and Claude are the first-class setup paths we document today. The protocol is not limited to them.
