Setup
Setup guide
- 11. In Switchy, navigate to Settings > Integrations and select Nylas MCP from the list. 2. Log into your Nylas dashboard at dashboard.nylas.com and generate a new API key under Developer > API Keys. 3. Copy the key and paste it into Switchy's connection form. 4. Grant scopes for the features you need: email.read_only for inbox access, calendar.read_write for scheduling, contacts.read_only for directory lookups. 5. Click Connect and wait for Switchy to verify the credentials. 6. Open any Project, type '@Nylas' in a message, and ask it to list your next three calendar events — if it returns results, the connection works. 7. To invoke specific actions, address the MCP directly in your prompt and describe the task in one or two sentences.
What teammates see: by default, memories from Nylas MCP are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

How Switchy teams use it
Starter prompts
Triage Inbox by Priority
@Nylas Review my unread emails from the last 24 hours and flag any that mention deadlines, approvals, or urgent requests. Summarize each flagged thread in one sentence.
Schedule Team Sync
@Nylas Check calendars for Sarah, Mike, and me this week. Suggest three 30-minute slots when all three of us are free, preferably between 10 AM and 3 PM.
Draft Follow-Up Sequence
@Nylas I sent an intro email to alex@example.com last Tuesday. Draft a polite follow-up checking if they had time to review the proposal, and suggest a call next week.
Extract Contact Info
@Nylas Find all contacts tagged 'Q1 prospects' and export their names, email addresses, and company names into a table.
Summarize Meeting Notes
@Nylas Look at yesterday's 'Product Roadmap' meeting on my calendar. Summarize the key decisions and list any action items assigned to attendees.
Example outputs
Illustrative - representative of the model's voice and quality, not literal recordings.
@Nylas show me all unread emails from the last 3 days that mention 'invoice' or 'payment'
Found 7 unread emails matching your criteria. The most recent is from accounts@acmecorp.com (subject: 'Invoice #4521 - Payment Due') received 2 hours ago. Others include reminders from billing@vendor.io, a payment confirmation from Stripe, and 4 internal finance threads. All messages contain attachments or inline payment links. Would you like me to summarize the outstanding amounts or draft responses?
This example assumes read access to the connected email account. Nylas requires OAuth consent for mail.read scope. Search performance depends on mailbox size — accounts with 100k+ messages may see slower queries. The MCP does not store email content locally.
@Nylas send a calendar invite for 'Q1 Planning' next Tuesday at 2pm, invite sarah@company.com and mark@company.com, include the Zoom link from my last meeting
Calendar event created: 'Q1 Planning' scheduled for Tuesday, January 14, 2025 at 2:00 PM EST. Invitations sent to sarah@company.com and mark@company.com. Zoom link (https://zoom.us/j/123456789) copied from your January 7th 'Sprint Review' event and added to the description. Both attendees will receive email notifications with calendar attachments.
This write operation requires calendar.write scope and assumes the Nylas account has calendar access configured. If attendees use external calendar systems, delivery depends on their mail server settings. The MCP cannot verify whether recipients accepted the invite without a subsequent read query.
@Nylas review my calendar for this week and draft a status update email summarizing what meetings I attended and what's coming up
This week you attended 12 meetings: 3 one-on-ones (with Sarah, Mark, and Lisa), 2 sprint planning sessions, 4 client calls (Acme Corp, Beta Inc, Gamma LLC, Delta Co), and 3 internal syncs. Upcoming: 5 meetings scheduled through Friday, including the board presentation Thursday at 10am and the product demo Friday at 3pm. Draft email prepared with bullet points for each category, highlighting key client touchpoints and internal milestones. Ready to send or would you like me to adjust the tone?
This synthesis example combines calendar read access with AI reasoning to generate a narrative summary. Accuracy depends on meeting titles and descriptions — vague calendar entries ('Sync', 'Catchup') produce less useful summaries. The MCP reads metadata only; it cannot access meeting transcripts or notes unless those are stored in event descriptions.
Use-case deep-dives
When Nylas MCP fits early-stage customer success teams
A 3-person customer success team at a B2B SaaS startup needs to track onboarding emails without leaving their AI workspace. Nylas MCP is a good fit here if your team already uses Nylas for email infrastructure and you need programmatic access to send status, read receipts, or thread history. The API key auth means one person sets it up and the whole team shares access through Switchy. The trade-off: if you're just reading Gmail or Outlook directly, the native email MCPs are simpler and free. Nylas wins when you need its unified API across providers or you're already paying for Nylas's email platform. If your onboarding flow lives in email and you want AI to summarize threads or draft follow-ups based on engagement data, this MCP closes that loop.
Nylas MCP for outbound sales teams with multi-provider email
A 6-person sales team uses a mix of Gmail and Outlook accounts and wants AI to help draft follow-ups based on reply timing and thread context. Nylas MCP makes sense if your team is already on Nylas's platform for calendar or contact sync. The MCP lets you query sent/received status, pull thread metadata, and feed that into AI prompts without switching tools. The boundary: if your team is under 10 people and everyone uses the same email provider, the Google Workspace or Microsoft Graph MCPs are cheaper and faster to set up. Nylas's value is the unified API when you have mixed providers or complex calendar/contact workflows. If you're researching whether to adopt Nylas, test the MCP in Switchy first to see if the AI integration justifies the platform cost.
When Nylas MCP helps support teams with email-heavy workflows
A 4-person support team handles 200+ tickets a week, many starting as email threads before moving to Zendesk or Intercom. Nylas MCP is worth it if you need AI to pull original email context, summarize long threads, or check if a customer replied outside the ticketing system. The API key setup means the team shares one connection and can ask AI to search recent emails by sender, subject, or date range. The limit: if your ticketing system already imports email threads cleanly, adding Nylas is redundant. This MCP shines when email is the source of truth and your support tool doesn't surface full thread history. If your team spends 10+ minutes per ticket hunting down email context, Nylas MCP in Switchy cuts that to seconds.
Frequently asked
What does the Nylas MCP do in Switchy?
The Nylas MCP connects your team's email and calendar accounts to Switchy's AI workspace. Your agents can read messages, check availability, and surface scheduling context without switching between apps. Since Nylas aggregates multiple providers (Gmail, Outlook, iCloud), one connection can unify your team's communication data regardless of which email service each person uses.
Do I need a Nylas account to use this MCP?
Yes. You'll need a Nylas developer account and an API key with the appropriate scopes for email and calendar access. Nylas acts as the middleware between Switchy and your actual email provider, so you're authenticating to Nylas, not directly to Gmail or Outlook. Check your Nylas dashboard to confirm which mailboxes are connected before adding the key to Switchy.
Can the Nylas MCP send emails or create calendar events?
That depends on which Nylas API scopes your key includes and which tools this MCP exposes. Nylas supports both read and write operations for email and calendars, but not all MCPs implement the full API surface. If you need send or create capabilities, verify the tool list in Switchy's integration settings before relying on it for outbound workflows.
How is this different from connecting Gmail or Outlook directly?
Nylas normalizes the APIs of multiple email providers into one interface, so you get consistent behavior whether your team uses Gmail, Outlook, or iCloud. Direct provider MCPs (if available) give you tighter integration with platform-specific features, but Nylas is the better choice if your team is split across providers or you want to avoid managing separate OAuth flows for each service.
Who on the team should connect the Nylas MCP?
Whoever owns your Nylas account and can generate API keys with the right scopes. This is usually an IT admin or the person who set up Nylas for your organization. Once connected in Switchy, all team members can use the MCP in their agents without needing their own Nylas credentials, but they'll only access data the Nylas account has permission to see.
