What's Wrong?

Title: MCP tool permission approval never reaches client — add_repo (and other gated tool calls) fail with “requires approval” indefinitely

Description:

In a Claude Code session (remote/web execution environment), calling a tool that requires interactive approval (add_repo from the claude-code-remote MCP server) consistently fails with:

Streamable HTTP error: Error POSTing to endpoint: MCP tool call requires approval

This happened on every retry (6+ attempts across the session), with no variation in the error. Earlier in the same session, other gated calls (AskUserQuestion, list_repos) intermittently failed with:

Tool permission request failed: Error: Tool permission stream closed before response received

and once with:

Denied by user

despite the user confirming they had not seen or interacted with any approval prompt. This suggests the approval request either never renders client-side, or the stream carrying the approval response closes/times out before the user’s client can respond.

Steps to reproduce:

1. Start a Claude Code session in the remote/web execution environment.
2. Have the assistant call a tool that requires interactive approval (e.g. add_repo to add a new GitHub repo to the session).
3. Observe the approval prompt does not reliably appear in the client, or the response stream closes before an answer is recorded.
4. Retries of the identical tool call return the same “requires approval” error with no prompt surfaced.

Impact: Session is completely blocked from using any tool gated behind interactive approval — no workaround available from within the chat.

Environment: Claude Code remote execution session (web/mobile client — exact surface unconfirmed by reporter).

What Should Happen?

Claude should be able to access GitHub Repository and continue
