chainlit MCP support for more commands

Is your feature request related to a problem? Please describe. It's related to MCP usage. When I add a local MCP tool, it says only 'npx' or 'uvx' commands are allowed.

Describe the solution you'd like Please don't set limitation on this or add a configuration to allow cusomized mcp command. Many local mcp servers doesn't onboard to npx or uvx.

What command are you using out of curiosity?

npm/node/python and customized command. For example, I've developed a mcp server and I have shared it with hundreds of people in my company. They installed the tool through a command similar to pip install xxx. Then they only need to add xxx as command in their mcp clients.

If it's security concern, it would be nice to be able to config the allow list.

@Ryuya1995 , you can update .chainlit/config.toml and add the commands to this list:

[features.mcp.stdio]
    enabled = true
    # Only the executables in the allow list can be used for MCP stdio server.
    # Only need the base name of the executable, e.g. "npx", not "/usr/bin/npx".
    # Please don't comment this line for now, we need it to parse the executable name.
    allowed_executables = [ "npx", "uvx", "python" ]
