# Cursor

> Install TierZero from the Cursor MCP marketplace and authenticate via OAuth.

Cursor publishes TierZero in its MCP marketplace. Install once and Cursor agents can call the [TierZero MCP tools](/references/mcp/overview) directly. Authentication is OAuth — no tokens to copy.

## Install

1. Open the [TierZero listing on the Cursor marketplace](https://cursor.com/marketplace/tierzero).
2. Click **Install** — Cursor adds the `tierzero` server to your MCP config.
3. Use a TierZero-backed action from any agent. Cursor prompts **Connect with tierzero** with an **Authenticate** button. Click it and complete the OAuth flow in your browser.

Once connected, Cursor agents can call `tierzero_ask` and `tierzero_fetch_context` whenever production context is relevant. The first call after a fresh install prompts for authentication; subsequent calls use the stored token.

## Usage

Ask the Cursor agent something that would benefit from production context — it will call `tierzero_ask` automatically. To pull a specific TierZero chat, investigation, or digest into the conversation, paste its URL and ask the agent to fetch context.

See the [overview](/references/mcp/overview) for what each tool does and the arguments it accepts.
