MCP Tools should be prefixed with either workflow name or server name

[airslashfury]

Bug Description

Ai Agent is unable to call multiple MCP's when they have identical names. This error is seen:

"You have multiple tools with the same name: 'list_tools', please rename them to avoid conflicts"

A lot of libraries have fixed this issue by doing the following:

Prefixes tool names with server name: Tool names are prefixed with {server_name}_{tool_name} format (e.g., serverA_run, serverB_run).

To Reproduce

create an agent workflow that calls two tools with identical list_tools commands

Expected behavior

the Agent builder should prefix the commands internally by prefixing tool with node name
