General questions
What plans support connectors?
What plans support connectors?
Connectors are available on Free, Pro, Max, Team, and Enterprise plans. See platform availability for more details.
What is MCP?
What is MCP?
MCP (Model Context Protocol) is an open standard by Anthropic enabling AI applications to connect with tools and data sources. It’s the technology powering Claude’s connectors. Learn more about MCP.
Can I use connectors on mobile?
Can I use connectors on mobile?
Yes, Claude for iOS and Android can access remote MCP servers. You can use previously configured servers, but adding new ones must be done through the web or desktop apps.
How do I enable connectors in my organization?
How do I enable connectors in my organization?
For Team and Enterprise plans, an Owner or Primary Owner must enable connectors in Admin Settings > Connectors. Individual users can then connect through Settings > Connectors.
Authentication & security
How does authentication work?
How does authentication work?
Most connectors use OAuth 2.0 for authentication. You’ll be prompted to authorize Claude to access your account on the connected service. Your permissions on the external service determine what Claude can access.
Can Claude modify my data?
Can Claude modify my data?
Most first-party connectors (Google, Microsoft, Slack) are read-only—Claude can search and analyze but cannot create, edit, or delete content. Custom connectors may have different permissions; always review what you’re authorizing.
How do I disconnect a connector?
How do I disconnect a connector?
Go to Settings > Connectors, find the connector you want to remove, and click “Disconnect.” This removes Claude’s access immediately.
What data does Anthropic collect from connectors?
What data does Anthropic collect from connectors?
Anthropic collects parameters, data, and responses from MCP tool calls. For Team/Enterprise plans, this data is not used for model training. Consumer plan users who opted into model training may have content used for improvement. See data handling policies.

Custom connectors
Can I build my own connector?
Can I build my own connector?
Yes! You can build custom connectors using the Model Context Protocol (MCP). See Building Custom Connectors for details.
How do I submit a connector to the directory?
How do I submit a connector to the directory?
Submit via the Connectors Directory review form. Your MCP server must meet security and compatibility standards, and all tools must include a
title and the applicable readOnlyHint or destructiveHint. Learn more about submitting custom connectors.What authentication methods are supported for custom connectors?
What authentication methods are supported for custom connectors?
Claude supports OAuth 2.0 with Dynamic Client Registration (DCR), OAuth 2.0 with Client ID Metadata Document (CIMD), OAuth 2.0 with Anthropic-held client credentials, custom connection-time credentials, and authless servers. A pure machine-to-machine
client_credentials grant is not supported—every connection requires user consent—but oauth_anthropic_creds provides a consent-gated alternative. See the authentication reference for details.Directory & partnership
Is there a fee to be in the directory?
Is there a fee to be in the directory?
No, and there never will be. Directory inclusion is free.
Can I get expedited review or preferred placement?
Can I get expedited review or preferred placement?
No. There is one standard review process for all connectors and no preferred-connector designation. The directory is a level playing field. See the partnership FAQ.
Do I need a contract with Anthropic?
Do I need a contract with Anthropic?
No. Standard directory inclusion only requires meeting the technical requirements and agreeing to the Software Directory Policy and Terms.
Does Anthropic train on my connector's data?
Does Anthropic train on my connector's data?
No. Connector terms do not grant Anthropic rights to train on partner data. See the partnership FAQ.
Should I build a remote or local server?

Remote is strongly recommended. Local server submission exists but is a secondary path.
What's the difference between a directory connector and a custom connector?
What's the difference between a directory connector and a custom connector?
Same runtime infrastructure. Directory connectors add Anthropic review, in-product discovery, and eligibility for Suggested Connectors. See directory vs custom.
Are first-party connectors like Gmail and Slack in the directory?
Are first-party connectors like Gmail and Slack in the directory?
Yes. Anthropic’s first-party integrations appear in the directory alongside third-party connectors.
Are connectors and MCP Apps available on mobile?
Are connectors and MCP Apps available on mobile?
Yes. All Claude.ai connectors, including MCP Apps, are available on iOS and Android. Adding new connectors must currently be done via web or desktop.
