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