# Crypto Price Alert Bot

Monitors cryptocurrency prices and sends alerts when assets hit your target prices.

## Toolkits Needed

You'll need access to these toolkits in your Arcade MCP Gateway:

- Slack
- GoogleSheets

## Setup Guide

1. ### Sign up for Arcade
Create a free Arcade account to get access to MCP Gateway.

[Create Arcade Account →](https://account.arcade.dev/)

2. ### Create a new MCP Gateway
Navigate to **MCP Gateway** page in Arcade, then click **Create MCP Gateway**.

Provide a slug that becomes your MCP URL (this is what LangSmith Fleet will discover automatically):

**Example:** If you choose slug `my-agent`, your MCP URL will be:

`https://api.arcade.dev/mcp/my-agent`

3. ### Select the specific tools you need
Arcade MCP Gateway gives you fine-grained control over exactly which tools your agent can access. Select these specific tools from the toolkits:

- Slack.SendMessage
- Slack.ListConversations
- Slack.GetMessages
- GoogleSheets.GetSpreadsheet
- GoogleSheets.UpdateCells
- GoogleSheets.CreateSpreadsheet

**Why this matters:** Instead of granting access to entire toolkits with hundreds of tools, you're selecting only the 6 specific tools this agent actually needs. This precision reduces risk and keeps your agent focused.

4. ### Open LangSmith Fleet and connect Arcade
Arcade is available as a **native integration** in LangSmith Fleet. Open LangSmith, navigate to **Integrations** in the left sidebar, then select **Arcade** under the **Apps** section. Click **Connect** to link your Arcade account.

[Open LangSmith Fleet →](https://smith.langchain.com/)

Click **Connect**, then click **Allow** to authorize Arcade. Your gateways will be discovered automatically.

5. ### Create your agent
