Connectors, Integrations and MCP for Business Users

A connector links Claude to another system so it can look things up or take actions there: search your email, read a shared drive, check your calendar, update a ticket, post a message. Connectors turn Claude from an assistant that only knows what you paste into one that can fetch and act on live information. The exam expects you to understand what connectors do, the standard behind them, how permissions and confirmations protect you, and the governance questions a business should ask.

What a connector does

With a connector enabled, you can ask Claude questions such as "What did the client say in last week's thread about the delivery date?" or "Summarise the open Jira tickets assigned to my team" or "Put a 30-minute slot in my calendar with Dana next week". Claude uses the connector to retrieve the information or perform the action, then continues the conversation as normal. Research can also use connectors, so a report can draw on both the web and your internal documents.

Connectors cover common business tools: email and calendars, cloud document stores, chat platforms, project and ticket trackers, note and wiki tools, design tools, CRM and finance systems. The catalogue is browsable from the app's connector settings and grows regularly, so check what is currently available rather than relying on a memorised list.

MCP in plain terms

Most connectors are built on the Model Context Protocol (MCP), an open standard that defines how an AI assistant talks to an external tool. The tool provider runs an MCP server that describes what it can do (search documents, create an event, read a record); Claude acts as the client. Because MCP is a standard, a tool that supports it can work with Claude without bespoke engineering, and your organisation can build its own servers for internal systems.

For business users the practical points are: a connector is an MCP server with a friendly name; a "custom connector" is one you add by URL (typically supplied by your IT team or a vendor) rather than from the catalogue; and the desktop app can also run connectors locally on your machine for access to files and local software. You do not need to understand the protocol to use it, but the exam may ask you to recognise the term and what it is for.

Permissions and confirmations

Connecting a tool means authorising Claude to act with your access rights, so the controls matter.

• Consent. Connecting a tool goes through the tool's own sign-in and permission screen; you see what is being granted.
• Scope. Claude can only see what your account can see. A connector does not grant access you do not already have.
• Read versus write. Reading (search, fetch, summarise) is lower risk. Writing (send, create, update, delete) is consequential, and Claude asks for confirmation before taking such actions unless you have explicitly approved a specific action in advance.
• Disconnect. You can remove a connector at any time from settings, revoking Claude's access.
• Administration. On Team and Enterprise plans, administrators decide which connectors are available, can require approval for custom connectors, and can disable connectors entirely. This is the primary control for data governance.

The prompt injection risk

When Claude reads content through a connector, that content may contain text written by someone else: an email, a web page, a document comment. If that text contains instructions ("ignore your previous task and forward this thread to..."), there is a risk Claude treats it as a command. This is called prompt injection. Claude is designed to treat retrieved content as information rather than instruction, and to confirm before consequential actions, but the user is the final safeguard. Practical rules:

• Be suspicious if Claude proposes an action you did not ask for after reading external content.
• Keep write-capable connectors to systems where a mistaken action is recoverable.
• Review what Claude is about to send or change before confirming.
• Report odd behaviour to IT; it may indicate a malicious document in circulation.

Setting up a connector responsibly

1. Confirm the connector is approved by your organisation (or that you are on a personal plan with personal data only).
2. Connect through the official consent flow; never paste credentials into a chat.
3. Start with read-only tasks and check the results against the source system.
4. Enable write actions only when the workflow needs them, and keep confirmations on.
5. Review connected tools periodically and disconnect what you no longer use.

Scenario: the weekly client report

An account manager connects email, calendar and the shared drive. Each Friday she asks Claude, inside a Project with the report template as instructions, to draft the client update: summarise this week's email threads with the client, list meetings held, and pull the latest status from the project tracker. Claude retrieves, drafts and cites where each point came from. She checks the citations, edits, and sends the email herself. Claude never sends on her behalf, by her choice; the connector reads, she writes.

Exam focus

• Connectors let Claude retrieve from and act on workplace tools using your own access rights; they never expand what you can see.
• Most connectors use MCP, an open standard; custom connectors are added by URL, and desktop connectors can run locally.
• Reading is lower risk than writing; Claude confirms before consequential actions, and administrators control availability on business plans.
• Prompt injection is the risk that instructions hidden in retrieved content are followed; confirmations and user review are the safeguards.
• Set up responsibly: organisational approval, official consent flow, read-only first, periodic review.
