The Best Claude Connectors for Business: Connect Your Tools to AI
A categorized guide to the connectors that let Claude work with the tools you already use
If you are still logging into separate apps, clicking through dashboards, copying data between tabs, and manually searching for information scattered across your tools — you are already behind.
Claude's connector marketplace has over 350 integrations — from Gmail to Salesforce to Shopify. Connectors let you interact with your business tools natively through Claude. Instead of switching between 10 apps to get your work done, you ask Claude — and it pulls from, writes to, and works across your tools directly.
This is not a nice-to-have. This is how modern businesses operate. The people using connectors are getting answers in seconds that used to take 15 minutes of clicking around.
This guide organizes the most impactful connectors by business function so you can find exactly what you need.
What Are Connectors (And What Is MCP)
The Plain English Version
Connectors are the user-facing name for integrations you toggle on and off in Claude's interface. When you "connect Gmail," you are telling Claude it has permission to access your email. When you "connect Notion," Claude can search your documents.
Plugins add new capabilities to Claude itself — new skills like legal document analysis or SEO auditing. For plugins, see our separate guide.
The short version: Connectors bring your data to Claude. Plugins teach Claude new tricks.
What Is Happening Under the Hood (MCP)
When you enable a connector, Claude is connecting to an MCP server using something called the Model Context Protocol. You do not need to understand the technical details, but knowing the relationship helps:
- MCP (Model Context Protocol) is the underlying standard that defines how Claude communicates with external tools and services. Think of it as the language Claude speaks when it talks to your apps.
- Connectors are the packaged, pre-built MCP integrations surfaced in Claude's interface that you can toggle on and off. They are MCP made simple — no configuration, no code, just click and connect.
Why does this matter to you? Because MCP is an open standard. That means the ecosystem of available connectors is growing fast, and if you have a custom tool your business relies on, a developer can build an MCP server for it. Your internal CRM, your proprietary database, your custom inventory system — they can all speak to Claude the same way Gmail and Slack do.
How Connectors Work
Setting up a connector typically takes 2-5 minutes:
- Go to claude.com/connectors or find the connector in Claude's interface
- Search for the tool you want to connect
- Click connect and authorize Claude to access your account
- Claude can now read from (and sometimes write to) that tool
Most connectors use OAuth — you log into your existing account, grant permissions, and you are done. No API keys, no code, no technical setup.
Once connected, you stop switching between apps. Instead of opening Slack to search for a conversation, opening your CRM to check a deal, and opening your calendar to see your schedule — you just ask Claude. It goes to the source and brings the answer back.
The 350+ Connector Ecosystem
Claude has connectors for nearly every major business tool. Below we have curated the most impactful ones, organized by what they help you do. This is not an exhaustive list — check claude.com/connectors for the full directory.
Communication and Collaboration
These connectors let Claude work with your messaging, email, and meeting tools.
Slack
Connect your Slack workspace so Claude can search conversations, surface insights from channels, and help you draft messages. Powerful for catching up on threads you missed, summarizing long discussions, and preparing for meetings based on recent team conversations.
Gmail
Give Claude access to your email for search, summarization, and drafting. Ask questions like "what did the vendor say about pricing in their last email?" or "summarize all emails from the finance team this week." Saves significant time on email management.
Outlook
The Microsoft equivalent of the Gmail connector. Same capabilities — search, summarize, and draft — for organizations on Microsoft 365.
Microsoft 365
Broader access across the Microsoft ecosystem including Word, Excel, PowerPoint, and SharePoint. Useful for organizations standardized on Microsoft tools.
Zoom
Connect your Zoom account for meeting access. Combined with transcription, Claude can search past meetings, summarize discussions, and extract action items.
Project and Task Management
These connectors let Claude interact with your project management tools.
Notion
Connect your Notion workspace so Claude can search your documents, databases, and wikis. Extremely useful if Notion is your team's knowledge base — ask Claude questions about your own documentation instead of searching manually.
ClickUp
Task management, project tracking, and workflow automation. Claude can search tasks, update statuses, and help you manage project timelines through ClickUp.
Asana
Connect your Asana workspace for task and project management. Search projects, update task assignments, track progress, and get status summaries without opening Asana.
Airtable
Connect your Airtable bases so Claude can query your structured data. Airtable users often have critical business data in bases — customer lists, inventory tracking, project databases. This connector lets Claude search and analyze that data directly.

Scheduling and Meetings
These connectors help Claude work with your calendar and meeting tools.
Google Calendar
Connect your Google Calendar so Claude can see your schedule, help with meeting prep, and understand your availability. Useful for asking Claude "what do I have tomorrow?" or "help me prepare for my 2pm meeting with Acme Corp."
Fathom
AI meeting transcription and note-taking. Connect Fathom so Claude can access your meeting transcripts, search past discussions, and extract action items. Particularly powerful for business owners who are in meetings all day and need help tracking decisions and follow-ups.

An open-source workflow automation platform. Similar to Zapier but with more control and customization. Popular with businesses that want automation without vendor lock-in.
Analytics
These connectors give Claude access to your business and product data.
Amplitude
Product analytics platform. Connect Amplitude so Claude can analyze user behavior, conversion funnels, and product metrics. Useful for product-led businesses that want AI-assisted analytics without needing a data team.

PostHog
Product analytics with feature flags and A/B testing. Connect PostHog for usage analytics, error tracking, and experiment results.
How to Build a Connected Workflow
Stop Clicking Around — Start Working Natively
Here is the mindset shift: your business tools should be feeding into Claude, not the other way around. Every time you manually log into an app to look something up, copy a number, or check a status — that is time you are spending as a human router between systems.
With connectors, Claude becomes the hub and your business tools become spokes. You ask a question in plain English, and Claude goes to the right tool, gets the answer, and brings it back. You never leave the conversation.
Example: A Monday morning without connectors
- Open Google Calendar, scan today's meetings (2 minutes)
- Open Slack, scroll through weekend messages (5 minutes)
- Open QuickBooks, check last week's numbers (3 minutes)
- Open Asana, review open tasks (3 minutes)
- Open Google Docs, start drafting your team update from memory (15 minutes)
The same Monday morning with connectors:
"Give me a briefing for today. Check my calendar, summarize anything urgent from Slack over the weekend, pull last week's revenue from QuickBooks, list any overdue tasks in Asana, and draft a team update covering all of it."
Five minutes. One conversation. Every data point pulled from the actual source.
This is not hypothetical. This is how businesses using connectors already operate. If you are still manually clicking between apps, you are leaving hours on the table every week.
Start with Your Biggest Data Silo
Do not connect everything at once. Identify the one tool where you spend the most time searching for information and connect that first. For most business owners, that is one of:
- Email (Gmail or Outlook) — if you spend a lot of time searching for past conversations
- Documents (Google Drive or Notion) — if you frequently need to reference stored information
- CRM (Salesforce or HubSpot) — if customer context is scattered across your sales tool
Get comfortable with one connector before adding more. Each one you add makes Claude more useful, but the first one teaches you the pattern.
Common Multi-Connector Workflows
Pre-meeting prep: Google Calendar + CRM + Email Claude sees your upcoming meeting, pulls the contact's history from your CRM, and surfaces relevant email threads — all in one request.
Weekly reporting: Analytics + Project Management + Slack Claude pulls metrics from your analytics tool, cross-references with completed tasks from your project manager, and summarizes what the team discussed in Slack — ready for your weekly update.
Customer escalation: Support + CRM + Slack When a customer issue comes in, Claude pulls their account history from the CRM, checks recent support interactions, and helps you draft a response informed by the full context.
Security and Data Considerations
Before connecting sensitive tools, consider these questions:
What Data Does Claude Access?
When you connect a tool, you grant Claude permission to read (and sometimes write) data from that tool. The scope varies by connector — some give read-only access, others allow Claude to take actions.
Always review the permissions prompt when connecting a new tool. It will tell you exactly what Claude can and cannot do with that connection.
Questions to Ask Before Connecting
- Does this tool contain sensitive customer data? If so, check your company's data handling policies and any relevant compliance requirements.
- Who else has access to this Claude workspace? If you are on a team plan, other team members might see data Claude pulls from your connected tools.
- Is the data Claude accesses governed by any regulations? Healthcare data (HIPAA), financial data (SOX), or European customer data (GDPR) may have specific requirements around AI processing.
- What happens to disconnected tools? When you disconnect a tool, Claude loses access. But information from past conversations that referenced that tool remains in your conversation history.
Best Practices
- Start with less sensitive tools — Connect your project management tool before your financial system
- Review permissions carefully — Only grant the access level Claude needs
- Use separate workspaces for sensitive data — If you need to keep client data isolated, consider separate Claude workspaces
- Audit your connections periodically — Remove connectors you are no longer using
