You are investigating an MCP server that fails on first launch but succeeds on subsequent...

The observed sequence provides direct causal evidence: the initial connection was interrupted while the operating system awaited authorization, and later attempts succeeded after permission was granted. The correct response is to verify repeatability, document the first-run requirement, and incorporate it into installation or onboarding instructions. Reinstalling the operating system is disproportionate and destroys useful diagnostic state. Disabling permission dialogs weakens endpoint security and bypasses the control rather than addressing expected behavior. Replacing a server that operates correctly after authorization misclassifies a transient initialization condition as a permanent defect. Claude Code uses explicit permission controls to balance capability and safety, so first-use approval behavior should be accommodated rather than suppressed. Claude Code permissions
