Nylas Plugin for Moltbot

Email, calendar, and contacts integration via Nylas API v3.

Built on the official Nylas Node SDK.

Quick Start

1. Get API Key - Sign up at https://dashboard.nylas.com and create an API key
2. Add API key to config:

   plugins:
     entries:
       nylas:
         config:
           apiKey: "nyk_v0_your_key_here"
   

3. Auto-discover grants:

   moltbot nylas status
   

   This will connect to Nylas, discover all authenticated accounts, and show the recommended configuration.

Prerequisites

Before using this plugin, you need to set up a Nylas account:

1. Create Nylas Account - Sign up at https://dashboard.nylas.com
2. Create Application - All apps → Create new app → Choose region (US/EU)
3. Get API Key - API Keys section → Create new key
4. Add Grants - Grants section → Add Account → Authenticate email accounts
5. Grant IDs are auto-discovered - The plugin will automatically find your authenticated accounts

    nylas:

Troubleshooting

"apiKey is required"

• Add your Nylas API key to the plugin configuration

"No grant ID provided"

• Set defaultGrantId or pass grant parameter to tools

401 Unauthorized

• Check that your API key is valid and not expired
• Verify the grant ID exists in your Nylas dashboard

404 Not Found

• Ensure the resource (message, event, contact) ID is correct
• Check that you're using the right grant for that resource
