The Connectors Directory is Anthropic's catalog of connectors for its AI assistant Claude, shown on claude.com as Connectors and plugins in the Claude Marketplace. A connector links Claude to an outside service, such as Google Drive, Slack, Notion or Asana, through the Model Context Protocol (MCP): an open standard by which an AI app calls the tools and reads the data of another program.
A Claude user browses the directory by category, reads what each connector does, and adds it to Claude from the listing; Claude can then use that service's tools inside a conversation. The page listed 1030 connectors when it was read. A company lists its own connector by submitting a remote MCP server, reachable over HTTPS, in the developer portal at claude.ai/directory/manage. It supplies a documentation URL, a privacy policy, an icon and a test account for reviewers, and every tool must carry annotations that say whether it only reads data or can change it. Submissions are reviewed, and some listings carry an Anthropic verified label.
Submitting requires a paid Claude plan. The pages do not state a fee for a listing.
