3030Additional Featured connectors: **BioMart**, **CellGuide** (CELLxGENE cell types), **ZINC** (purchasable chemical space), and **Ketcher Chemistry** (2D molecule sketcher).

32Four Directory connectors are available from the [connector directory](https://claude.com/connectors) and are accessible in Claude Science and other Claude products: **PubMed**, **Clinical Trials**, **ChEMBL**, and **bioRxiv**. On Team and Enterprise plans, directory connectors appear only after an admin adds them.
32Four Directory connectors are available from the [connector directory](https://claude.com/connectors) and are accessible in Claude Science and other Claude products: **PubMed**, **Clinical Trials**, **ChEMBL**, and **bioRxiv**. On Team and Enterprise plans, directory connectors appear only once they're added for your organization.

3434By choosing to enable connectors, you authorize Claude to use the optional enabled resources on your behalf and confirm you have the necessary rights and licenses. These resources and content they reach may be subject to third-party terms (viewable in Settings), and you are solely responsible for compliance. On Team and Enterprise plans, an admin in your organization gives this authorization for the team when turning Claude Science on and choosing which connectors members can use, and you remain responsible for complying with those terms.

3838Name a source in your request, or describe what you need and Claude chooses from available connector tools. Connector queries appear in the conversation as expandable code steps. Featured connectors you've previously enabled run without a permission card. Connectors you add yourself prompt for approval per tool, with Once, This conversation, This project, or Global scope.

4040The databases behind Featured connectors are on the network allowlist in groups under Settings > Network. Turning off a group disables the connectors that depend on it.

42## When the connector you need isn't listed
43 
44Connectors you've added in claude.ai, and ones your organization has added for you, also appear in Claude Science under **Settings > Connectors**. If one needs a sign-in, the app opens claude.ai, where you connect it with your own account.
45 
46If what you need still isn't there, try these:
47 
48* **Ask Claude first.** Many public databases and tools work without a connector, because the code Claude runs can reach websites directly. The first time Claude needs a new site, a permission card asks you to allow it. If your organization manages the list of allowed sites, ask an admin to add it. See [Sandbox](/docs/claude-science/core-concepts#sandbox).
49* **Add one from the Connectors Directory.** Go to **Settings > Connectors > Add connector > Browse Connectors Directory**, which opens the directory in claude.ai. On Pro and Max plans, add the connector there and it appears in Claude Science. On Team and Enterprise plans, you may be able to add it yourself; if not, an admin can add it for your organization. On a Team plan, select **Request** on the connector's listing to ask your admins.
50* **Add one yourself.** If the tool's maker gives you a web address for its connector (sometimes called an MCP server URL), go to **Settings > Connectors > Add connector > Remote URL** and paste it in. If the maker gives you a command to run instead, choose **Local command** and enter it there. On Team and Enterprise plans, this works only if your organization allows custom connectors. See [Custom connectors](/docs/claude-science/custom-connectors).
51* **Ask the tool's maker.** If no connector exists yet, ask them to build one and [submit it to the Connectors Directory](/docs/connectors/building/submission#submit-your-connector).

53Admins can find the full set of options in [Add a connector your organization needs](/docs/claude-science/admin-controls#add-a-connector-your-organization-needs).
