Dify version

1.8.1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

I am using the open-source version 1.8.1 of dify. When adding tools to the agent, if the number of tools exceeds 10, the add button is not available. Is there a limit to the number of tools required here?

If it is for MCP services, do MCP services count as one quantity, or do each MCP interface count as one quantity?

✔️ Expected Behavior

When using third-party tools such as cherryStudio, I control the tools count based on the MCP service level, not the MCP interface level. I hope to seek some help.

Actual Behavior

Cannot continue adding when there are more than 10 tools
