Summary

• Downgrade Zod from v4.0.17 to v3.21.4 to maintain backward compatibility

Problem

The LINE Bot MCP Server v0.3.1 throws MCP error -32603: keyValidator._parse is not a function when using mcp__line-bot__push_text_message. This occurs because Zod 4.x has breaking changes where the _parse method was renamed to parse.

#224

@4geru 4geru force-pushed the down-grade-the-zod-under-4-0-0 branch from 5117abe to 1b875b0 Compare August 22, 2025 14:25

@4geru
Thank you for modification 🙇
Could you please confirm just two points:

  • Please resolve the conflict.
  • Libraries are automatically updated by Renovate. To prevent this for zod, please add the following entry to renovate.json5.
  ...
  "ignoreDeps": [
    "zod"
  ]
}
