sap-cloud-sdk>=0.43.0 is incompatible with mcp>=2.0.0 — MCP tools silently fail to load

[stefan-reichenbach]

Describe the Bug

sap-cloud-sdk versions >=0.43.0 access InitializeResult.serverInfo (camelCase) inagent.py. mcp 2.0.0 renamed this attribute to server_info (snake_case), causing an AttributeError that is caught silently per-server. The result is that 0 MCP tools are loaded for any connected MCP server — the agent LLM receives an empty tool list and responds with "tool not available" for every prompt that requires an MCP-backed tool.

The failure is particularly hard to diagnose because:

• Network calls to the MCP server succeed (no connectivity error)
• No exception propagates to the caller
• The agent appears healthy but produces no tool-based output

Steps to Reproduce

1. Create an agent using sap-cloud-sdk>=0.43.0 and mcp>=2.0.0
2. Register any MCP server
3. Send a prompt that requires a tool call
4. Observe that the LLM reports the tool is unavailable / no tools were found

Expected Behavior

MCP tools load correctly and are available to the LLM regardless of the mcp package version.

AttributeError: 'InitializeResult' object has no attribute 'serverInfo'.
Did you mean: 'server_info'?

(Raised during MCP server initialization; caught silently.)
