[BUG] Tool names should be <=64 characters

[combiz]

Describe the bug
Currently, the tool name is concatenated from its function name/other paths. This can often go over the 64 char limit used in common MCP implementations, which results in errors.

To Reproduce
Try a tool with a name >64 characters with for example n8n or langchain with openai/gpt-4.1-mini. It returns a 400 Provider returned error.

Possible Solution
Allow the user to override the default (concatenated) tool name with a custom name. Or omit some path prefixes.

System Info
n8n/langchain/openai models on Linux

i do believe in the documentation its said that this can be overriden using operation_id parameter when defining the route

That's handy, though it's a little cumbersome if there are a large number of routes. And routes >60 chars (cursor) or 64 chars (claude, n8n) often can't be used at all so it would be good to fix them at point of creation.
