Setup Guide

1

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:

Gmail.ListEmails
Gmail.SendEmail
Gmail.ReplyToEmail
GoogleDocs.CreateDocumentFromText
GoogleDocs.GetDocumentAsDocmd
GoogleDocs.EditDocument
GoogleDocs.SearchDocuments
GoogleDocs.GetDocumentById
GoogleDocs.CreateBlankDocument
Choose your tools in Arcade MCP Gateway

Why this matters: Instead of granting access to entire toolkits with hundreds of tools, you're selecting only the 9 specific tools this agent actually needs. This precision reduces risk and keeps your agent focused.
