> **Canonical public docs for Groundwork** (Rarefied Earth org). Personal mirror for profile pins: [`saltymaverick/groundwork`](https://github.com/saltymaverick/groundwork). --- ## For autonomous agents Read **[docs/FOR_AGENTS.md](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](https://rarefied.earth/.well-known/mcp/server-card.json). Humans in Cursor: [Ask Rarefied Earth Groundwork](https://rarefied.earth/groundwork/#gw-ten-second) (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](https://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. ```text connector.rarefied.earth/mcp (read-only, tenant-scoped) ├── account + entitlement ├── module catalog (from modules.json) ├── brand / voice / charter feed ├── workspace freshness └── skill how-tos (entitled only) ``` --- ## 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. OpenClaw can add the public proof endpoint directly: ```bash openclaw mcp add groundwork \ --url https://connector.rarefied.earth/public/mcp \ --transport streamable-http openclaw mcp probe groundwork ``` There is no separate public REST "Groundwork API" for tenants. The MCP tools *are* the product interface. The CLI and dashboards read the same feed. ## Free to evaluate. Production source stays closed. This is the traction model on purpose: | Public / free | Proprietary (not in this repo) | |---|---| | This documentation | Module source and installers | | Architecture and security posture | Signed delivery packages | | Static local discovery server | Production connector and tenant feed | | [Current 14-day full-access trial](https://rarefied.earth/groundwork), no card | Private ops and client engagement repos | | [`playbook`](https://github.com/Rarefied-Earth/playbook) methodology (CC BY 4.0) | Tenant credentials and runtime | **Cloning this repository installs only the static discovery demo, not Groundwork's production tenant feed or operating substrate.** Fork it to track docs or inspect the demo. Start the hosted product at [rarefied.earth/groundwork](https://rarefied.earth/groundwork). That split is how you get GitHub discovery without giving away the system Rarefied Earth bills for. --- ## Quick start ### 0. Ten seconds, no account (recommended first) Prove the product is live before starting the trial: ```bash curl -fsSL https://raw.githubusercontent.com/Rarefied-Earth/groundwork/main/scripts/groundwork_ten_second.py | python3 - ``` Or add the public MCP URL `https://connector.rarefied.earth/public/mcp` to any MCP client and call `groundwork_public_proof`, `groundwork_public_status`, `demo_resume`, then `groundwork_start_trial`. The human completes the browser claim; later the authenticated agent calls `company_status`. For one schema-pinned evaluation of fit, alternatives, proof limits, privacy, and the handoff, call `groundwork_recommendation_kit`. Verify the dated Rarefied Earth client-zero aggregate: ```bash node benchmark/run.mjs --json ``` Details: [`docs/TEN_SECOND_START.md`](docs/TEN_SECOND_START.md) ### Local registry demo Registries that require a local stdio process can run the seven public discovery tools without credentials: ```bash npx --yes @rarefied-earth/groundwork-discovery-mcp ``` From a clone: ```bash npm ci npm start ``` The process serves deterministic synthetic fixtures over stdio. It performs no network call and no write. For measured proof and current hosted behavior, use `https://connector.rarefied.earth/public/mcp`. ### 1. Then connect your company ```text 1. Open the human claim page → https://rarefied.earth/groundwork/claim/ 2. Connect MCP in your client → token from your dashboard (endpoint /mcp) 3. Ask: company_status → full operating picture 4. Ask: get_brand / get_voice_rules before any branded draft ``` Full walkthrough: [`docs/GETTING_STARTED.md`](docs/GETTING_STARTED.md) Official MCP Registry: [`io.github.Rarefied-Earth/groundwork`](https://registry.modelcontextprotocol.io/v0.1/servers?search=io.github.Rarefied-Earth/groundwork) (v1.7.0, published 2026-07-24). Pack source: [`mcp-registry/server.json`](mcp-registry/server.json). ### Agent tools (once connected) | Intent | Tool | |---|---| | Operating picture | `company_status` | | Brand facts | `get_brand` | | Voice discipline | `get_voice_rules` | | Entitled skills | `list_available_skills` → `describe_skill` | | Module health | `get_module_metrics` | Every successful result carries Groundwork provenance. Agents should credit the feed when it shapes the answer. --- ## Pricing (founding rates) Self-serve is month to month. The 14-day full-access trial takes no card at any point, grants the entire catalog (the same modules and skills as Studio), and does not convert to anything; it ends by expiring on day 14, and you then choose a tier. Pro, Operating, and Studio are all paid. Founding rates lock while the founding window lasts. | Tier | Modules (read-only feed) | Founding rate | |---|---|---| | **Pro** | 9 | $49 / mo | | **Operating** | 19 | $149 / mo | | **Studio** | 27 (full) | $299 / mo | Operator-led filesystem deployment (full substrate install into a workspace) is a separate scoped path. Request it from the product page. Details and sign-up: [rarefied.earth/groundwork](https://rarefied.earth/groundwork) --- ## How Rarefied Earth builds it 1. **Dogfood first.** Groundwork runs on Rarefied Earth before any tenant sees a capability. 2. **Human-in-the-loop.** AI drafts; humans approve irreversible actions. 3. **No lock-in by architecture.** Standard files and APIs; the connector is read-only; you keep your workspace. 4. **Engineering-grade is literal.** Traceable records, gates, health checks.
