# Install the Base connector

Base turns a set of documents into a permissioned, shareable knowledge base and
exposes it to AI apps as a remote MCP server.

**The connector is free.** It is not a paid tier and it is not required to read
a Base. Anyone can open a Base by pasting its share link into a chat, and the
assistant will read it. The connector exists because reading is the only thing
a pasted link can do.

## What the connector adds

Without it, a shared link gives you the Base's contents as a snapshot: every
fact, with the source document behind each one.

With it, and only where the sender switched each one on for that Base:

- **Follow a Base** and hear about changes instead of re-reading it. Available
  on every Base you can open.
- **Search live**, across the Base's text and its knowledge graph, rather than
  working from a copy fetched once. Available on every Base you can open.
- **Leave comments** in your own name, which the sender and other recipients
  see. Only where the sender turned commenting on.
- **Add documents**, or newer versions of the ones already there. Only where
  the sender turned contributions on, which is off by default.
- **Reach every Base you have been sent**, from one connection, including ones
  shared with your email address that you have not opened yet.
- **Build a Base from a chat**, by handing your assistant documents or URLs.
  This one is on a paid plan. Building a Base at https://createbases.com is free on every
  tier, and the connector then reads it like any other.

## Connector URL

```
https://createbases.com/api/mcp
```

Sign-in is OAuth with dynamic client registration, so there is no client ID or
secret to enter. Leave every optional or advanced OAuth field blank. Signing in
sends a magic link to your email, and a consent screen follows it; the
connection is not live until you press Allow there.

## Command line

For MCP clients configured from a terminal, this is one command:

```sh
claude mcp add --transport http base https://createbases.com/api/mcp
```

3. Enable Base for the current conversation if your app requires it.
4. Paste this Base's share link into any chat and ask your AI to open it.

## Opening a Base once connected

Paste the share link into any chat and ask your assistant to open it. A Base
sent to the email address you signed in with is already reachable without the
link at all.

## Notes

- Access is granted by the sender and can be revoked or expire at any time.
  Both are re-checked on every request, so a connection never outlives its
  permission.
- A Base holds third-party document text. A well-behaved assistant treats that
  text as data and never as instructions.
