AI Email Response Assistant | Arcade

AI Email Response Assistant

Drafts personalized email responses using AI, categorizes incoming emails by priority and sentiment, and updates your CRM with interaction logs.

Toolkits Needed

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

Setup Guide

  1. Sign up for Arcade

    Create a free Arcade account to get access to MCP Gateway. Create Arcade Account →

  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:

    • Gmail.ListEmails
    • Gmail.SendEmail
    • Gmail.ReplyToEmail
    • OutlookMail.ListEmails
    • OutlookMail.CreateAndSendEmail
    • OutlookMail.ReplyToEmail
    • Hubspot.ListContacts
    • Hubspot.CreateContact
    • Hubspot.UpdateContact

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.

  1. 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 →
