How to handle drop queries?

[ksgnextuple]

From the code i see that we require a confirmation code to drop queries, but when i tried that it always said token is invalid. Any way to solve this?

Hi @ksgnextuple

What MCP client are you using, and how are you passing the token back to the MCP server?

If you can share more context that would help (even a screen recording or whatever)

Actually am making use of the mcp server as a langchain tool in a multiagent workflow. Made use of the convert_mcp_to_langchain_tools to convert it.

Below are the few screenshots.

The first tool call does not have the token as expected, but the second time around the agent learns that a token needs to be passed and does pass it, but then getting the token expired error. Ideally I would want to implement a human in the loop here.

Hi @ksgnextuple

Thanks for the extra context

When sending your follow-up requests with confirmation token, the window for passing that token may have expired

Options:

1. Set the security.tokenExpirationMinutes config setting to a bigger number (it defaults to 5 minutes). You set this value via custom config file (see: docs) or via CONFIG_SECURITY_TOKEN_EXPIRATION_MINUTES='<YOUR VALUE>' env var (see: docs).

2. Disable confirmation tokens by setting the disableDestructiveOperationTokens config setting to true (see: docs). You can do this via custom config file or via CONFIG_DISABLE_DESTRUCTIVE_OPERATION_TOKENS=true env var.

Hope that helps, interested to know how it goes

Cheers

Hi @furey the second option worked, but option 1 still doesn't work, actually when the token is being sent it is definitely within 5 minutes of creation.

Hi @ksgnextuple

I'm not that familiar with LangChain or langchain-mcp-tools-py and I'm not sure this is the reason option 1 doesn't work, but if the same MongoDB Lens server doesn't persist across your agent calls, then the MongoDB Lens token functionality cannot work as tokens are stored in memory on the server they were created on

As I said, dunno if that's the cause, but glad option 2 worked for you all the same 😃

Thanks @furey, i think that might be the case, where the previous session is closed and a new one is started. Will try to figure it out.
