TL;DR

The most likely fix is to ensure the mcp__plugin_telegram_telegram__reply and mcp__plugin_telegram_telegram__react tools are properly installed and configured.

Guidance

1. Verify tool installation: Check if the mcp__plugin_telegram_telegram__reply and mcp__plugin_telegram_telegram__react tools are installed and up-to-date.
2. Check configuration: Review the system configuration to ensure these tools are properly configured and enabled.
3. Review error logs: Analyze the error logs to identify any patterns or additional error messages that may indicate the root cause of the issue.

Example

No code snippet is provided as the issue seems to be related to tool installation and configuration rather than code.

Notes

The issue description lacks specific details about the system and tool versions, which might be necessary for a more precise solution. The error messages suggest a problem with finding specific tools, which could be due to installation, configuration, or version compatibility issues.

Recommendation

Apply a workaround by verifying the installation and configuration of the mcp__plugin_telegram_telegram__reply and mcp__plugin_telegram_telegram__react tools, as the error messages directly point to these tools not being found.
