10 best apps for Cursor + founders
Ranked by leverage. The order matters — start at the top, get one win, then add the next.
1. Gmail
The single highest-leverage connection. Triage inbox, draft replies in your voice, and let Cursor flag the three threads you actually need to answer today.
The Gmail toolkit covers reading messages and threads, sending and replying, drafting, managing labels, and searching the mailbox with full Gmail query syntax. Your agent can triage thousands of messages, reply in your voice, and never lose track of the threads that actually need an answer.
A few things you can do with Gmail and Cursor once it is connected:
- Triage today's inbox into reply-needed, FYI, and trash
- Draft a reply in your voice to a long thread with all the context above
- Find every email from a customer over the last quarter and summarise the relationship
- Set up a label-based workflow that auto-routes invoices to your bookkeeper
Schedule, reschedule, and protect deep-work blocks. Cursor can read your week and rebuild a saner calendar in one prompt.
The Google Calendar toolkit lets your agent list, create, update, and delete events across multiple calendars, manage attendees and conferencing details, find free/busy windows, and respond to invites. Recurring events and timezone handling are baked in.
A few things you can do with Google Calendar and Cursor once it is connected:
- Find a 30-minute window that works for five people next week
- Auto-block focus time around every meeting longer than an hour
- Reschedule conflicting meetings when a higher-priority one lands
- Create a recurring 1:1 with the right Meet link and agenda doc
3. Slack
Catch up on team channels, post async updates, and have Cursor turn a long thread into a one-line decision summary.
The Slack toolkit lets your agent read channels, threads, and DMs, post messages and rich blocks, manage reactions, schedule messages, search history, and work with users and channels. It supports both bot and user-token actions, so the same agent can post 'on behalf of' a workspace bot or a specific person.
A few things you can do with Slack and Cursor once it is connected:
- Summarise everything posted to #engineering overnight
- Cross-post a launch announcement to ten channels with the right tone for each
- React to a customer complaint thread and DM the account owner
- Schedule a recap message to fire at 9am Monday
4. Notion
Where the company wiki, OKRs, and board memos live. Cursor reads existing context before drafting anything new.
Composio's Notion toolkit covers the full database and page surface — querying databases with filters, creating and updating pages, appending blocks, managing properties, and reading existing content. Your agent can search across the entire workspace, follow page hierarchies, and write back in the same Notion-block structure as the surrounding content.
A few things you can do with Notion and Cursor once it is connected:
- Query the PRD database for everything tagged 'Q2' and summarise progress
- Create a meeting note page from a transcript with proper headings and toggles
- Update the status property on a row when a related GitHub PR merges
- Append daily standup blocks to a running team page
5. Linear
Stay close to what the team is shipping without nagging. Pull weekly progress and draft investor-update bullets from real issues.
The Linear toolkit gives your agent first-class access to issues, projects, and cycles — creating, updating, commenting, assigning, moving across states, and filtering by any combination of label, team, or workflow. It can also work with sub-issues, attachments, and project updates, which is what makes Linear useful as an agent's task surface.
A few things you can do with Linear and Cursor once it is connected:
- Triage the inbox: tag, assign, and prioritise every new bug from the last 24 hours
- Draft a release-notes summary from issues that shipped this cycle
- Convert a Slack bug report into a well-scoped issue with reproduction steps
- Post weekly project updates with progress against the cycle goal
6. Stripe
Live revenue, churn, and subscription data. Cursor can answer board-prep questions in seconds instead of building another sheet.
The Stripe toolkit reaches customers, subscriptions, invoices, charges, refunds, payouts, and webhook events. Read-only mode is the safer default for founders — your agent can answer revenue and churn questions without ever moving money.
A few things you can do with Stripe and Cursor once it is connected:
- Pull MRR, ARR, and net new churn for the current month
- Find every customer whose subscription failed in the last 7 days
- Generate a board-ready revenue chart from the last 12 months
- Draft refund decisions with full transaction context
7. Attio
For founder-led sales. Cursor can log calls, pull deal context before a follow-up, and draft thoughtful next-steps from your last meeting notes.
The Attio toolkit handles people, companies, deals, lists, notes, and custom objects with the same flexibility Attio gives in the UI. Your agent can assert records (upsert by email or domain), create entries against any list, and write structured notes from a meeting transcript.
A few things you can do with Attio and Cursor once it is connected:
- Upsert a contact and company from a calendar invite, with the right list assignment
- Log meeting notes against an account and update the deal stage
- Pull every deal in a list and draft personalised follow-ups
- Run an enrichment pass on stale records using public sources
8. Brex
For startups on Brex. Cursor can read company spend, surface anomalies, and approve or flag transactions from a chat — without opening another dashboard.
The Brex toolkit covers cards, transactions, vendors, expense reports, and reimbursements. Your agent can read company spend, surface anomalies, approve or flag transactions, and generate vendor or department spend summaries on demand.
A few things you can do with Brex and Cursor once it is connected:
- Summarise this month's spend by category and flag anything unusual
- Pull every transaction over a threshold without a memo and chase owners
- Generate a vendor spend report for the next finance review
- Approve a batch of pending reimbursements that match policy
9. Calendly
For sales, hiring, and partner conversations. Cursor can pre-brief you on every invitee from their LinkedIn and prior emails.
The Calendly toolkit can list and inspect scheduled events, fetch invitee details, manage event types, send invitations, and reschedule or cancel meetings. It pairs well with a CRM connection — pull invitee context before every call.
A few things you can do with Calendly and Cursor once it is connected:
- Pre-brief every invitee on tomorrow's calendar from their email and LinkedIn
- Cancel and re-send invites for a rescheduled office hour
- List all upcoming user research interviews with their context
- Pull no-show data and follow up automatically
10. Twitter
Schedule posts, monitor mentions, and turn launches or hires into a sequence of well-crafted tweets without leaving the chat.
The X toolkit lets your agent post tweets and threads, read user and post data, manage likes and reposts, search recent posts, and pull engagement metrics. The thread-from-doc workflow is the most common use — turn long-form into a sequence of well-paced posts.
A few things you can do with Twitter and Cursor once it is connected:
- Turn a 2,000-word blog post into a 10-tweet thread
- Monitor mentions and surface the ones worth replying to
