AuthSources represent services that handle authentication and authorization. It can primarily be used by Tools in two different ways:

• Authorized Invocation is when a tool to be validate by the auth service before the call can be invoked. Toolbox will rejected an calls that fail to validate or have an invalid token.
• Authenticated Parameters replace the value of a parameter with a field from an OIDC claim. Toolbox will automatically resolve the ID token provided by the client and replace the parameter in the tool call.

Example

The following configurations are placed at the top level of a tools.yaml file.

{{< notice tip >}} If you are accessing Toolbox with multiple applications, each application should register their own Client ID even if they use the same "kind" of auth provider. {{< /notice >}}

authSources:
  my_auth_app_1:
    kind: google
    clientId: YOUR_CLIENT_ID_1
  my_auth_app_2:
    kind: google
    clientId: YOUR_CLIENT_ID_2

After you've configured an authSource you'll, need to reference it in the configuration for each tool that should use it:

• Authorized Invocations for authorizing a tool call, use the requiredAuth field in a tool config
• Authenticated Parameters for using the value from a ODIC claim, use the authSources field in a parameter config

Specifying ID Tokens from Clients

After configuring your authSources section, use a Toolbox SDK to add your ID tokens to the header of a Tool invocation request. When specifying a token you will provide a function (that returns an id). This function is called when the tool is invoked. This allows you to cache and refresh the ID token as needed.

Specifying tokens during load

{{< tabpane >}} {{< tab header="LangChain" lang="Python" >}} async def get_auth_token(): # ... Logic to retrieve ID token (e.g., from local storage, OAuth flow) # This example just returns a placeholder. Replace with your actual token retrieval. return "YOUR_ID_TOKEN" # Placeholder

for a single tool use:

authorized_tool = await toolbox.load_tool("my-tool-name", auth_tokens={"my_auth": get_auth_token})

for a toolset use:

authorized_tools = await toolbox.load_toolset("my-toolset-name", auth_tokens={"my_auth": get_auth_token}) {{< /tab >}} {{< /tabpane >}}

Specifying tokens for existing tools

{{< tabpane >}} {{< tab header="LangChain" lang="Python" >}} tools = await toolbox.load_toolset()

for a single token

auth_tools = [tool.add_auth_token("my_auth", get_auth_token) for tool in tools]

OR, if multiple tokens are needed

authorized_tool = tools[0].add_auth_tokens({ "my_auth1": get_auth1_token, "my_auth2": get_auth2_token, }) {{< /tab >}} {{< /tabpane >}}
