The best Claude connectors

Plug Claude into the apps where your work actually lives — Drive, Slack, GitHub, and more. Which ones are worth it, the three to turn on first, and how to combine them without opening a security hole.

Most people use Claude as a smart chat box. The people getting 10x out of it have quietly plugged it into their real tools — so it can read their docs, catch up on Slack, and act across their stack without a single copy-paste. This is how you do that, and which connectors are actually worth turning on.

1. What a connector actually is

By default, Claude only knows what you paste into the chat. A connector plugs Claude into the apps where your real work lives — your Drive, your Slack, your GitHub — so it can read from them and take action in them without you copy-pasting anything.

Under the hood they run on MCP (Model Context Protocol) — an open standard for letting AI talk to tools. You don't need to know that to use them, but it's why the same connector ecosystem works across Claude apps and why there are hundreds of them.

Two kinds, and the difference matters:

  • Read connectors — Claude can search and summarize your stuff. "What did we decide in the Q3 planning doc?" Low risk, huge value.
  • Action connectors — Claude can do things: send a Slack message, create a GitHub issue, draft an email. More powerful, so more care.

2. How to turn one on (60 seconds)

It's genuinely a couple of clicks — no code for the official ones:

  • Open Claude → Settings → Connectors.
  • Browse the Connectors Directory (hundreds of options, ~30 categories) or search for the app you want.
  • Click Connect → you'll be sent to that app to sign in and approve access (OAuth). You never hand Claude your password — the app hands over a scoped token.
  • Back in a chat, Claude can now use it. Just ask in plain English: "Search my Drive for the pricing deck."

Connectors live on paid Claude plans and are managed per-account. When you approve one, read what it's asking for — some want read-only, some want read and write. Grant the least you need (more on this in the security section).

3. Best for knowledge & documents

This is where connectors pay off fastest — stop Claude from being an amnesiac and let it read where your team already writes things down.

  • Google Drive — the highest-value connector for most people. Search across every doc, summarize a folder, compare two versions, pull facts out of a 40-page PDF. If you only add one, add this.
  • Notion — if your team runs on Notion, this lets Claude search, read, and update pages. Great for "turn this messy note into a proper doc in our workspace."
  • Google Sheets — read and analyze spreadsheet data without exporting. "What's the trend in the revenue tab?"
  • Box / OneDrive / Dropbox — same idea as Drive for teams standardized on those.

4. Best for communication & inbox

  • Slack — search channel history, catch up on a thread, post an update, draft a message. "Summarize what I missed in #launch today" is the killer use case.
  • Gmail — read, triage, and draft email in your voice. Turn a 60-email inbox into a prioritized list, or draft five replies in one go.
  • Google Calendar / Outlook — "what's my day look like," find a slot, prep for the next meeting from its docs. Pairs perfectly with the email connector.

Email and Slack are where action connectors earn their keep — but also where a wrong move is most visible. Keep these on "draft, don't send" behavior in your head: let Claude write it, you hit send.

5. Best for developers

  • GitHub — read repos, issues, PRs and commits; check a PR diff, open an issue, comment. Huge for "explain what changed in this PR" or triaging a backlog.
  • Linear / Jira / Asana — pull your tickets, see what's assigned to you, create tasks from a conversation. "What's on my plate this sprint?"
  • Sentry — surface real errors and analyze what's breaking, straight from your monitoring.
  • A database (Postgres / Supabase) — let Claude query your data directly and explain it. Powerful, and exactly the kind of connector to keep read-only.

6. The multiplier: automation connectors

This is the one people miss. A single automation connector gives Claude access to thousands of apps at once, instead of adding them one by one.

  • Zapier — connects Claude to 7,000+ apps. If a dedicated connector doesn't exist for your niche tool, Zapier almost certainly bridges it. The most flexible way to let Claude act across your stack.
  • Make / Composio — same idea, different flavors. Composio in particular is built for wiring lots of tools into AI cleanly.

Think of it this way: dedicated connectors are deep (rich, native access to one app); automation connectors are wide (shallow-but-broad access to everything). Most people want one or two deep ones plus one wide one.

7. Best for design & content

  • Canva — generate and edit designs, decks, and graphics from a prompt, in the tool you already publish from.
  • Figma — read designs and design systems so Claude's output matches your actual components, not generic mockups.
  • Gamma — turn a prompt or outline into a finished deck or one-pager.

8. The three I'd turn on first

If you're staring at hundreds of options and don't know where to start, don't add ten. Add these three and live in them for a week:

  • 1. Google Drive (or your team's doc store) — instantly makes Claude aware of everything you've already written.
  • 2. One communication connector — Slack if you're on a team, Gmail if you live in your inbox. This is where the daily time-savings show up.
  • 3. Zapier — the escape hatch. The moment you think "I wish Claude could also touch [X]," Zapier probably already can.

Everything else you add later, when a specific job demands it. More connectors isn't better — relevant connectors are.

9. The real unlock: combining them

One connector is handy. The magic is when Claude works across them in a single ask, because it has the context to actually do it:

  • "Read the spec in Drive, then create the matching tickets in Linear."
  • "Summarize today's Slack in #support and draft a status email to the team."
  • "Check the failing tests in Sentry, find the related GitHub PR, and explain what broke."

That cross-tool reasoning is the whole point. Each connector you add doesn't just do its own thing — it becomes context the others can use.

10. Security & good hygiene

Connectors are powerful because they touch real data and can take real actions. A few rules keep that a feature, not a footgun:

  • Grant the least access that does the job. If read-only is offered, take it. Claude summarizing your Drive doesn't need permission to delete files.
  • Only connect what you actually use. Every connector is a door. Don't leave doors open to tools you're not using — remove them in Settings → Connectors.
  • Know who built it. Some connectors are official; many are built by third-party developers. For anything with write access to sensitive systems, check the source before approving.
  • Treat "action" connectors like a new intern. Great at drafting; you review before it sends, posts, or deletes anything that matters.
  • Be careful mixing untrusted content with action connectors. If Claude reads an email or webpage, treat instructions inside it as data, not commands — this is how prompt-injection attempts work.
  • Revoking is instant. If anything feels off, remove the connector; access is cut immediately.

11. Can't find one? Build it

Because connectors run on the open MCP standard, you (or a developer) can wire up almost anything — an internal API, a niche SaaS, your own database — as a custom / remote MCP connector and add it to Claude by URL.

You don't need this on day one. But it's why the ecosystem grows so fast, and why "there's no connector for my tool" is rarely a real dead end — either an automation connector bridges it, or someone can build one in an afternoon.

12. Quick pick by who you are

  • Founder / operator: Google Drive + Gmail + Zapier. Reads your docs, runs your inbox, touches everything else.
  • Developer: GitHub + Linear + Sentry. Your code, your tickets, your errors — Claude sees the whole loop.
  • Marketer / creator: Google Drive + Canva/Gamma + Slack. Content, design, and team comms.
  • Team lead: Slack + Notion + your PM tool (Asana/Linear/Jira). Claude becomes the person who's actually read everything.
