"What are Claude connectors and Enterprise Search?" — the short answer is a connector lets Claude search and read data inside the systems your organisation already uses, and Enterprise Search is a ready-made project that queries all of them at once. Unlike uploading files, nothing is copied out, and access still follows the permissions set in the source system. This article covers what can be connected, how setup works, and the limits worth knowing before you promise anything to management.
In one line: Connectors let Claude read directly from Google Drive, Gmail, Slack and Microsoft 365. Enterprise Search is the "Ask Your Org" project that searches across all of them at once — available on Team and Enterprise plans only.
How a connector differs from uploading files
There are two fundamentally different routes for getting organisational data in front of Claude, and picking the wrong one is the most common reason enterprise AI pilots stall.
| Aspect | Uploaded files / project knowledge | Connector |
|---|---|---|
| Freshness | Frozen at the moment of upload | Read from the source at query time, so always current |
| Access control | Anyone in the room sees every file in the room | Follows each user's existing permissions in the source system |
| Maintenance burden | Someone has to keep replacing outdated files | None — no copy is made |
| Best for | Regulations, manuals and templates that rarely change | Email, working files and chat that change daily |
One sentence to remember: static documents belong in project knowledge; moving data belongs behind a connector. Exporting a report from a system and re-uploading it every week is doing the machine's job by hand.
What can be connected, and what it can actually do
The list below follows Anthropic's own documentation (checked 1 September 2026). Note that several connectors do more than read — they can draft and send email or create calendar events.
| System | What it can do | Documented limits |
|---|---|---|
| Google Drive | Search documents, read files, upload, share and save files back | Cannot see images, comments or suggestions inside Google Docs |
| Gmail | Search, read, draft, send, reply, forward and manage labels | Attachment content is inaccessible — metadata only |
| Google Calendar | View, create, update and delete events; manage attendees | Complex queries may require multiple API calls |
| Microsoft 365 | Search across SharePoint, OneDrive, Outlook and Teams | An admin must grant Microsoft Entra consent first |
| Slack | Serves as the "chat" source for Enterprise Search | Only channels the individual user already belongs to |
| Custom / remote MCP | Connect in-house systems through MCP | The server must be reachable over the public internet, because the connection originates from Anthropic's cloud rather than the user's machine |
That last row matters most for on-premise deployments: an ERP running inside a LAN with no public URL cannot be reached by a remote MCP connector. It needs a gateway that exposes only what you intend to expose, behind authentication. The protocol basics are covered in what MCP is.
Enterprise Search: one question across every system
Enterprise Search is a pre-built project called "Ask Your Org" that appears in the sidebar with optimised instructions already in place and your organisation's connectors wired in. One question fans out across documents, chat and email simultaneously.
It is available on Team and Enterprise plans only, and setup requires connectors in at least two categories.
| Category | Required? | Examples |
|---|---|---|
| Documents | Required | Google Drive or SharePoint |
| Chat | Required | Slack or Microsoft Teams |
| Optional but recommended | Gmail or Outlook |
Setup always happens in two layers: an owner enables it for the organisation, then each individual authenticates with their own account. That second layer is precisely the mechanism that keeps permissions intact.
| Step | Who | Action |
|---|---|---|
| 1 | Organisation owner | Organization settings > Connectors > Browse connectors, then "Add to your team" |
| 2 | Organisation owner | Click "Ask Your Org" > "Set up for your org" > pick the documents and chat connectors > name the project and add a description |
| 3 | Each user | Authenticate to each service with their own credentials before searching |
| To disable | Organisation owner | Admin settings > Capabilities turns the feature off organisation-wide |
Permissions: read the whole sentence
Anthropic's documentation is explicit: "You only see search results from data you have permission to access in the original systems", and it states that no external indexing of connected data takes place. That is an accurate selling point and genuinely good news for a security team.
But finish the sentence: "permissions in the original system" means that if your source permissions are loose, Claude will be loose in exactly the same way — faithfully. A payroll folder shared with "anyone in the organisation with the link" three years ago becomes dramatically easier to find, because until now nobody knew where it was. Audit sharing permissions in Drive and SharePoint before switching Enterprise Search on. See data governance for Claude in the enterprise.
A second point for the legal team: connectors reach third-party services that operate under their own terms and may process data outside the country. Organisations with PDPA or similar obligations should scope explicitly which connectors are enabled and over which data sets.
Limits worth knowing before you promise anything
| Limit | Practical consequence |
|---|---|
| Enterprise Search is not available on mobile apps | Web and Claude Desktop only — do not plan the executive demo on a phone |
| Queries count toward standard plan usage limits | Heavy search teams hit limits sooner; factor this into seat planning |
| Gmail attachment content is not readable | A supplier quote sent as a PDF attachment still has to be opened manually |
| Google Docs comments and images are invisible | Documents where the decision lives in the comment thread summarise incompletely |
| Source-provider API quotas apply | Very large mailboxes search more slowly — expected behaviour, not a fault |
Assess this before enabling custom connectors: Anthropic warns plainly that custom connectors link Claude to services that have not been verified by Anthropic. Connect only services you trust, and disconnect unused ones periodically. Once an AI can read external content, prompt injection becomes part of your threat model — see prompt injection, the number one AI agent vulnerability.
How to ask so Enterprise Search answers well
"Ask Your Org" is not a keyword box. It takes questions as sentences and fans them out across systems, so questions that pin down a time window and demand provenance perform noticeably better than bare keywords.
A question that works: "Summarise what we agreed with this supplier about warranty terms, based on email and chat from the last three months, and state which message or file each point came from." That uses all three strengths at once — cross-system reach, a bounded time window, and a requirement to cite the source.
A question that disappoints: "What policies do we have?" The system has to guess where to look, and the answer comes back broad and incomplete. The principle is the same one described in the guide to prompting Claude: the tighter the scope, the more verifiable the result.
Phase it: organisations that switch on every connector at once usually end up unable to tell which system a problem came from. Enable the documents connector first, run it for two weeks, collect the questions people actually ask, then add chat and email in that order.
What about the ERP?
To be direct: Saeree ERP does not yet publish an official MCP server for Claude to call, and we would not recommend rushing to let an AI read an ERP database directly anyway. The reason is scope rather than technology — an ERP holds payroll, cost prices and approval limits, and opening a broad read channel in round one creates work you will have to undo later.
The sequence we recommend instead: (1) connect the Drive or SharePoint where working documents already live, (2) measure which questions people genuinely ask, (3) only then decide which specific reports from the ERP system to expose through a permission-aware gateway — not the whole database.
The dividing line holds: the ERP stays the system of record with an audit trail; Claude is the search and drafting layer above it, never the place transactions are recorded.
Good fits and poor fits today
| Good fit | Poor fit |
|---|---|
| "Where is the meeting summary for project A, and who edited it last?" | "What is the remaining budget on project A right now?" |
| Pulling scattered email, chat and drive context into one summary | Work requiring 100% completeness, such as statutory audit |
| New joiners finding documents they do not know exist | Organisations that have never audited their file-sharing permissions |
| Drafting a customer reply grounded in the existing thread | Approvals or postings that need an auditable trail |
Conclusion
Connectors change the working model from "copy data out so the AI can see it" to "let the AI look where the data already lives" — the right direction for both freshness and security. Enterprise Search bundles those channels into a single question box, requires at least a documents and a chat connector, and is limited to Team and above.
The work that decides whether this succeeds is not on Anthropic's side. It is housekeeping on yours: how tidy your file-sharing permissions are. Enterprise Search grants nobody new access — it simply turns "unfindable because nobody knew where it was" into "found in three seconds".
Enterprise Search does not grant anyone new access. It reveals how loose the access you granted three years ago really was.
