Feature Request: MCP Notifications Support - tools/list_changed

[linw1995]

Background & Motivation

Crush is an excellent agent tool with great potential. To enhance its capabilities further, I believe adding comprehensive MCP (Model Context Protocol) feature support would be valuable, particularly MCP Notifications handling.

Current Work & Implementation

I've been working on implementing MCP Notification support in my fork: https://github.com/linw1995/crush/tree/feat/mcp_notifications
The goal is to handle tools/list_changed notifications, which would allow:

• Dynamic tool discovery and updates
• Better integration with MCP servers
• Real-time tool availability changes

Issues Encountered

During implementation, I've encountered several challenges that I'd like to discuss with the community:

• The tools/list request will block indefinitely when initiated during the Tool Calling procedure.
• The mcpTools field in the agent struct has been updated, but the Tool Calling procedure still returns "Tool not found".

Questions for Discussion

• What would be the preferred approach for handling dynamic tool updates?
• Are there any architectural considerations I should be aware of?
