Its hosted MCP server lets an assistant read the products, suppliers, sales, inventory, pricing, projects and open actions that the signed-in person can already see, so questions are answered from your Twelfth workspace rather than from a pasted spreadsheet. | | | | --- | --- | | **Endpoint** | `https://api.twelfth.ai/mcp` (Streamable HTTP) | | **Sign-in** | OAuth 2.1 with your Twelfth account. Choose the workspace and approve the tools; no key to copy | | **Access** | Reads by default. Changes are opt-in: tick **Allow changes** when connecting and the assistant can create, complete or snooze your own actions and run your own routines, as you. None raises an order or changes a price | | **Scope** | One workspace, as the person who connected: their role, remits and categories. Owners and admins see and can end every connection | | **Registry** | [`ai.twelfth/workspace`](https://registry.modelcontextprotocol.io/v0.1/servers?search=ai.twelfth/workspace&version=latest), published from the twelfth.ai domain | | **Docs** | [twelfth.ai/ai](https://twelfth.ai/ai) · [MCP guide](https://twelfth.ai/developers/mcp) | You need a Twelfth workspace to connect. [Book a demo](https://twelfth.ai/book-a-demo) if your team doesn't have one yet. ## How it connects ```mermaid flowchart LR A["AI assistant<br/>Claude · ChatGPT<br/>Copilot · Cursor"] -- "1 · adds the URL" --> S["Twelfth sign-in<br/>pick workspace<br/>approve tools"] S -- "2 · scoped token" --> A A -- "3 · tool calls" --> M["Twelfth MCP<br/>api.twelfth.ai/mcp"] M -- "4 · as the member" --> W[("Your<br/>workspace")] ADM["Owner / admin"] -.

Cursor sends you to Twelfth to sign in on first use: ```json { "mcpServers": { "twelfth": { "url": "https://api.twelfth.ai/mcp" } } } ``` ### Claude Code ```sh /plugin marketplace add twelfth-ai/twelfth-mcp /plugin install twelfth@twelfth ``` Or just the server: `claude mcp add --transport http twelfth https://api.twelfth.ai/mcp` ### VS Code and GitHub Copilot [<img alt="Install in VS Code" src="https://img.shields.io/badge/VS_Code-Install_Twelfth-0098FF?style=flat-square&logo=visualstudiocode&logoColor=white">](https://insiders.vscode.dev/redirect/mcp/install?name=twelfth&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A//api.twelfth.ai/mcp%22%7D) [<img alt="Install in VS Code Insiders" src="https://img.shields.io/badge/VS_Code_Insiders-Install_Twelfth-24bfa5?style=flat-square&logo=visualstudiocode&logoColor=white">](https://insiders.vscode.dev/redirect/mcp/install?name=twelfth&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A//api.twelfth.ai/mcp%22%7D&quality=insiders) Or add it to `.vscode/mcp.json` (or your user `mcp.json`): ```json { "servers": { "twelfth": { "type": "http", "url": "https://api.twelfth.ai/mcp" } } } ``` Start the server, sign in to Twelfth when VS Code asks, then use the tools from Copilot Chat in agent mode. ### GitHub Copilot CLI ```sh copilot plugin marketplace add twelfth-ai/twelfth-mcp copilot plugin install twelfth@twelfth ``` This adds the server and the `twelfth-workspace` skill. Copilot asks you to sign in to Twelfth the first time a tool runs. ### Gemini CLI ```sh gemini extensions install https://github.com/twelfth-ai/twelfth-mcp ``` Then run `/mcp auth twelfth` inside Gemini CLI to sign in. The extension adds the server and the `twelfth-workspace` skill. ### Claude, ChatGPT, Gemini and other clients Add a custom connector with the URL `https://api.twelfth.ai/mcp` and complete the Twelfth sign-in. Per-assistant guides: [twelfth.ai/ai](https://twelfth.ai/ai). ### Servers and scripts A workspace owner or admin can create a labelled, tool-limited key under **Settings → AI & agents → Create an API key** and send it as `Authorization: Bearer <key>`. ## Security and governance | Control | How it works | | --- | --- | | **Reads by default** | Every tool reads unless the person ticks **Allow changes** on the consent page. Write tools are offered only over OAuth, only after that opt-in, and act only on the person's own actions and routines. Workspace keys never make changes. Orders, prices and other commercial decisions are still committed by people inside Twelfth | | **Least privilege** | An OAuth connection inherits the member's role and remits and stops working when they leave the workspace. Tools are chosen at consent | | **Admin visibility** | Owners and admins see every connection, the client and version that connected, and can end any of them. An ended connection is refused on its next request | | **Keys** | Created only by owners and admins, labelled by environment, limited to selected tools, stored hashed and shown once | | **Audit** | Each call is logged with tool, outcome, time and duration. Tool results are never stored or sent to analytics; only their size is recorded | | **Compliance** | Controls, sub-processors and our SOC 2 / ISO 27001 programme: [trust.twelfth.ai](https://trust.twelfth.ai) | ## Skills The plugin ships eight [Agent Skills](https://agentskills.io). The server also serves them over the MCP Skills extension (`skills/list`), so an assistant that supports it gets them without installing anything. **Retail analysis.** These work on a spreadsheet or pasted data. No Twelfth account is needed. | Skill | Use it to | | --- | --- | | `sales-decline-diagnosis` | Find out why sales of a category, supplier or product fell: split the change into units, price, mix and returns, then test the causes cheapest first | | `category-review` | Review a category: its role, scorecard, availability, return on stock, range and promotions, and what to do next | | `range-review` | Decide which lines to keep, cut or add, using where a cut line's shoppers would go and stock you've already bought | | `supplier-offer-review` | Read a supplier's stock list or offer against your sales and cover: what to buy, how much, and what's missing | | `competitor-price-check` | Check price position on matched products: listing errors, pack sizes, member and promo prices, a weighted index, and whether to match | **Twelfth.** These need the Twelfth connection. | Skill | Use it to | | --- | --- | | `twelfth-workspace` | Get started: which workspace is connected, what the tools can see, and how changes work | | `twelfth-weekly-trading-brief` | Write Monday's brief: actions due, suppliers waiting, cover pressure, price position and three things to do first | | `twelfth-competitor-pricing` | Answer pricing questions from tracked sets, competitor comparisons and price history | Each retail-analysis skill ends with what changes when Twelfth is connected. ## What's in this repo This repository holds client configuration only; the server is hosted and operated by Twelfth AI Pty Ltd. | Path | What | | --- | --- | | `plugins/twelfth/` | The plugin: MCP config for Cursor (`mcp.json`) and Claude Code (`.mcp.json`), and the eight skills above | | `.cursor-plugin/`, `.claude-plugin/` | Marketplace manifests for Cursor and Claude Code | | `gemini-extension.json`, `skills/` | The Gemini CLI extension. `skills/` is a copy of the plugin's skills; `node scripts/validate-template.mjs` fails if they drift | ## Support - Questions and enterprise enquiries: [hello@twelfth.ai](mailto:hello@twelfth.ai) - Security reports: [security.txt](https://twelfth.ai/.well-known/security.txt) - Privacy: [twelfth.ai/legals/privacy](https://twelfth.ai/legals/privacy) <p align="center"> <a href="https://twelfth.ai"> <picture> <source media="(prefers-color-scheme: dark)" srcset="assets/wordmark-light.svg"> <img src="https://raw.githubusercontent.com/twelfth-ai/twelfth-mcp/HEAD/assets/wordmark.svg" alt="twelfth.ai" height="28"> </picture> </a> <br><sub>Twelfth AI Pty Ltd · ACN 695 769 138 · Australia</sub> </p> The contents of this repository are MIT licensed.
