Access Credentials in Custom Tools.

[yavisht]

Are credentials exposed to custom tools? Is there a way to access them instead of hardcoding in the function?

[HenryHengZJ]

yes for now. we'll make the improvment for you to access credential within custom tool function

[kashbadami]

@HenryHengZJ has this been done already?

[yavisht]

@HenryHengZJ - If we can use Credentials in custom tools, can you please share some steps? It would be nice to get it by using a syntax like this:

$credentials.<credential-name>

@kashbadami - I am not sure if we can access credentials but you can pull in a value from a custom variable for now.

From what I know so far,

You can use properties specified in Input Schema as variables with prefix $:

Property = userid
Variable = $userid

You can get default flow config:

$flow.sessionId
$flow.chatId
$flow.chatflowId
$flow.input

You can get custom variables:
$vars.<variable-name>

UPDATE: Nevermind my answer. I did not uncomment the E2B.credential file. It works. Maybe you can pass your credential that way.

Is this why I cannot use the -Create New- for E2B tool credential or is it something completely different?

I get the following error message:
