RangeError: Maximum call stack size exceeded during MCP hook processing

Description

Claude Code crashed with a stack overflow error during what appears to be MCP hook/tool processing. The session was abruptly terminated and returned to the terminal prompt.

Error Message

RangeError: Maximum call stack size exceeded
(Use `node --trace-uncaught ...` to show where the exception was thrown)
Node.js v22.13.0

Context

• Action being performed: Running a bash command (scp to sync files to a remote server)
• When it occurred: After the command completed successfully, during post-tool processing
• Result: Session terminated, returned to shell prompt

Stack Trace (minified)

The visible stack trace showed recursive calls involving:

• queryTracking
• PostToolUse
• hookPermissionResult
• hook_cancelled
• hook_blocking_error
• toolPermissionContext

This suggests infinite recursion in the MCP hook permission/result handling system.

Environment

• Node.js: v22.13.0
• OS: macOS
• Claude Code: Latest version as of 2025-01-08

Reproduction

Difficult to reproduce reliably - happened once during a sync operation that had been run multiple times before without issue.

Screenshot

A screenshot was captured showing the minified JavaScript stack trace before the crash.
