Describe the Bug

When executing the following code:

from composio_langchain import LangchainProvider
from composio import Composio

composio = Composio(api_key=<composio_api_key>, provider=LangchainProvider())
user_id = "xxx"
tools_1 = composio.tools.get(
        user_id,
        toolkits=["Benzinga"],
)

as error came out:

File "/Users/jakcieshi/anaconda3/envs/nt_py13/lib/python3.13/site-packages/composio_langchain/provider.py", line 140, in wrap_tools
    return [self.wrap_tool(tool=tool, execute_tool=execute_tool) for tool in tools]

        schema_params=schema_params
    )
  File "/Users/jakcieshi/anaconda3/envs/nt_py13/lib/python3.13/site-packages/composio/utils/shared.py", line 347, in get_signature_format_from_schema_params
    parameter = Parameter(
        name=param_name,
    ...<2 lines>...
        default=default,
    )
  File "/Users/jakcieshi/anaconda3/envs/nt_py13/lib/python3.13/inspect.py", line 2802, in __init__
    raise ValueError('{!r} is not a valid parameter name'.format(name))
ValueError: 'parameters[date]' is not a valid parameter name

I think the problem here is caused by the inspect.Parameter that checks the validity of name.

Steps to Reproduce

1. Create a Composio MCP Server for Benzinga
2. Running the code:

from composio_langchain import LangchainProvider
from composio import Composio

composio = Composio(api_key=<composio_api_key>, provider=LangchainProvider())
user_id = "xxx"
tools_1 = composio.tools.get(
        user_id,
        toolkits=["Benzinga"],
)

I also find that such problem exists in many toolkits as well, like News_api and etc.
