Base
Documentation

Connect your AI to Base.

Base exposes every Base you own or were sent as a remote MCP server. Connect once and your AI can search your Bases, read the sources behind every fact, and, where a sender allows it, comment and contribute documents.

Try Base before connecting

Every new account starts with Base Tutorial, a Base that explains Base, so there is a cited answer to inspect right away. You can use Base in your browser without connecting an AI.

What Base is

Base turns a set of documents into a permissioned, shareable knowledge base. The owner uploads files, Base extracts a cited knowledge index, and a share link gives recipients a read-only site built from it. The connector is the same content for AI apps: a remote MCP server your assistant can query directly.

The connector is free and is not required to read a shared Base. Pasting a share link into any chat already works. Connecting adds live search, following a Base for updates, commenting, contributing documents where the sender switched that on, and reaching every Base sent to your email address from one connection.

In Claude, add it from the directory

Base is listed in the Claude connector directory, so there is no URL to paste and no advanced settings to leave blank. Open the Base listing and press Connect, or find it under Customize → Connectors → Browse connectors. Sign-in and the consent screen below are the same either way.

Team and Enterprise admins can hide the directory for a workspace. If the listing is not reachable, the connector URL below still works by hand, and it is the only path in every other app while those listings are in review.

Connector URL and authentication

The connector is a remote MCP server over Streamable HTTP at:

https://createbases.com/api/mcp

  • Authentication is OAuth 2.1 with dynamic client registration and client ID metadata documents. There is no client ID or secret to enter; leave every optional or advanced OAuth field blank.
  • Signing in sends a one-time link to your email. A Base consent screen follows it, and the connection is not live until you press Allow there.
  • For MCP clients configured from a terminal: claude mcp add --transport http base https://createbases.com/api/mcp

Setup, app by app

Hosts move these settings around on their own schedule. If a menu is not where a step says, search the app's settings for “connector” or ask the assistant itself to walk you through its current flow.

Claude

https://claude.ai/directory/createbases

  1. Open the Base listing in the Claude connector directory, or find it under Customize → Connectors → Browse connectors and search for Base.

  4. Ask your AI to list your Bases. Ones sent to your email address are in that list too, with no link to paste.

If your workspace has the directory turned off, add it by hand instead:

  1. Open Claude and go to Customize → Connectors.
  2. Choose Add → Add custom connector, name it Base, paste the Base connector URL, and leave the advanced settings blank.
  3. Complete the Base magic-link sign-in, then press Allow on the Base consent screen.
  4. Ask your AI to list your Bases. Ones sent to your email address are in that list too, with no link to paste.

ChatGPT

  1. Open Plugins in ChatGPT, choose Add → Create custom MCP server, and name it Base.
  2. Paste the Base connector URL as the Server URL and leave Authentication set to OAuth.
  3. Press Create, accepting ChatGPT's note about custom servers if it shows one, then complete the Base magic-link sign-in and press Allow on the Base consent screen.
  4. Ask your AI to list your Bases. Ones sent to your email address are in that list too, with no link to paste.

Grok

  1. Open grok.com/connectors and choose New Connector → Custom.
  2. Name it Base and paste the Base connector URL.
  3. Complete the Base magic-link sign-in, then press Allow on the Base consent screen.
  4. Enable Base for the conversation if Grok asks.
  5. Ask your AI to list your Bases. Ones sent to your email address are in that list too, with no link to paste.

Other

  1. Add the Base connector URL wherever your AI app accepts custom connectors.
  2. Complete the Base magic-link sign-in, then press Allow on the Base consent screen.
  3. Enable Base for the current conversation if your app requires it.
  4. Ask your AI to list your Bases. Ones sent to your email address are in that list too, with no link to paste.

Opening a Base once connected

Paste a share link into any chat and ask your assistant to open it. Ask it to follow the Base if you want to hear about changes. A Base sent to the email address you signed in with is already in your list, with no link to paste.

What the tools can and cannot do

Reading tools cover your library and anything shared with you: listing and searching Bases, reading documents, the knowledge graph, timelines, contradictions, and comments. Writing tools create Bases, add files and comments, and manage task threads; they act only on Bases where you have that permission. Tools that can replace what readers see, cut off access, post in your name, or change a published page are marked so your AI app asks before running them. Earlier versions of a document are always kept and can be restored.

Every request is checked against the sender's permissions at the moment it is made. Access is deny by default: a claim publishes to you only when you can see every source behind it, and revocation or expiry cuts access on the next request.

Managing and revoking connections

Review active AI clients at Settings · AI connections. Revoking a connection stops that client from making new authenticated requests immediately.
