🐛 Bug Description

I just updated to the last version of kagent (0.7.17)

I run 2 manifest one for the mcp playwright tools and other for creating an agent.

When creating the mcp tool and the agent through the cli everything is working fine, but if I create the agent using the UI and after creating I try to bind the tools using the UI as well it is not working or at least it is showing a Agent not Accepted message.

I also tried to create the agent and bind the tools (all at once) and is not creating any agent and inside the log it is showing the following error:

🔄 Steps To Reproduce

1. Install mcp server tool using manifest and set it up into the same kagent namespace
2. Create an agent using the UI (this should work)
3. After agent is up and ready, bind some tools
4. It will show Agent not accepted

🤔 Expected Behavior

Agent created correctly using the MCP tools

📱 Actual Behavior

Showing Agent Not Accepted or not creating the agent at all

💻 Environment

Kubernetes version: v1.34.4
Browser: Chrome 145.0.7632.76
