The Connectors Directory lists connectors from Anthropic and from third-party developers, and each one shows how much Anthropic has reviewed it. Use this page to understand what those labels mean before you connect one.
If you build connectors and want yours listed, see List your own connector.

​
Connector labels

A connector’s label reflects the level of review it received. The label affects how the connector is displayed and discovered in the directory, not how the connector itself functions: once connected, a Community connector has the same capabilities and access as any connector you grant.

​
Verified

Anthropic has tested a Verified connector’s tools for quality and compatibility, and it met the Software Directory Policy requirements at the time of review. Verified connectors show a checkmark next to their name. Verification means Anthropic has reviewed the connector more closely than a Community connector. It isn’t a security audit or a guarantee of how the connector will perform. The developer operates the connector and controls its tools, which can change after review.

​
Community

A third-party developer built a Community connector. Anthropic screens Community connectors before listing them but hasn’t reviewed them in depth. Anthropic doesn’t control the tools a Community developer makes available and can’t guarantee they will work as intended or won’t change, so only connect to developers you trust. Community connectors show a Community label in the directory and in Customize > Connectors. Before you connect one, Claude shows a reminder that it hasn’t been reviewed in depth.

​
Custom

You added a Custom connector yourself, and Anthropic hasn’t reviewed it. Custom connectors explains how to add one.

​
Directory listing versus custom connectors

The directory is a catalog of connectors, and listing is optional. Connectors in the directory and custom connectors you add yourself use the same technology, so if you have a connector’s URL, you can add it as a custom connector whether or not it’s in the directory. Listing a connector in the directory makes it discoverable by other people and gives it a review label: a checkmark if Anthropic has verified it, or Community if Anthropic has screened it but not reviewed it in depth. Listing doesn’t change the tools the connector exposes. Directory vs custom has a detailed comparison.

​
Stay safe with third-party connectors

Whatever the label, this advice applies to any connector built by someone other than Anthropic:
  • Only connect to servers from developers and organizations you trust
  • A connector’s developer controls which tools it exposes and can change them at any time
  • Anthropic doesn’t run a third-party connector’s servers and doesn’t control how it handles your data
  • Carefully review requested permission scopes during authentication
  • Stay aware of prompt injection risks, even though Claude has built-in protections
  • Monitor for unexpected changes in tool behavior

​
List your own connector

If you build connectors and want yours in the directory, start with the connector pre-submission checklist and then submit your connector. When you submit a server, Anthropic scans it automatically for policy compliance and, by default, lists it in the directory as a Community connector. Anthropic may then escalate listings flagged as highly useful to Claude users to Verified review, which is higher touch and slower, and in which reviewers run a functional test of each tool. That escalation is assessed automatically. There’s no separate application for the Verified label, and you don’t need to take any action.
