Tool Execution Failed: Error: tool 'name' not found in any workbench

[Alex-Wenner-FHR]

I am using a combination of MCP workbench and StaticWorkbench where static workbench are just locally defined tools. I keep seeeing this error however when calling StaticWorkbench tools. Tool Execution Failed: Error: tool 'local_tool_name' not found in any workbench. But MCP calls work just fine. Am I doing something incorrectly here?

workbench=[
              *[McpWorkbench(mcp_param) for mcp_param in self._mcp_server_params],
              StaticWorkbench(
                  tools=[
                      FunctionTool(
                          name="test_tool",
                          description="Should return a string as a test",
                          func=test_tool,
                      )
                  ],
              ),
          ],

I am passing multiple mpc stdio params in which is why my MCPWorkbench looks this way. You could simplify it with one and still am seeing the same issue.

I am on latest, 0.6.4

This is saying that the model called a tool "local_tool_name", yet such tool does not exist. How many tools do you have in total in all workbenches? Having too many tools sometimes confuse model.

Correct, and its "calling" the right tool, but that error occurs. It only seems to be the case when using static tools. MCP workbenches work fine. I do have alot of tools, but I have confirmed the StaticWorkbench tools are present in every request, the model is correctly calling it by name, but its not found.
