What
Connectors are links from claude.ai to outside services that can bring files into a session, which is one conversation with Claude Code. Some organizations set a policy that keeps web search apart from connector data. Under that policy, Claude Code now blocks one side once the other has been used.
- Web search, web fetch and browser tools become unavailable once a session holds, or may hold, files downloaded from claude.ai connectors. The message reads: "Web search, web fetch, and browser tools are unavailable for now: this session holds, or may hold, files downloaded from claude.ai connectors".
- Connectors are likewise blocked after web tools have been used, until the policy is known.
- The session records whether connector downloads are held, including downloads from earlier in a session you resume.
- The deny message now depends on that recorded state, checked through
lastingConnectorDownloads(). One message is used when the state is "held" and a different one when it is "unread". Before, the code chose between three fixed messages. - The
folder_not_kept_out_of_gitmessage was shortened.
Why
If your organization uses this isolation policy, web tools or connectors may switch off partway through a session, and the wording you see depends on whether connector files are known to be in the session. Resuming a session keeps the restriction from earlier downloads.
