AuthServices

AuthServices 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.

authServices:
  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 authService 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 authServices field in a parameter config

Specifying ID Tokens from Clients

After configuring your authServices 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

• LangChain

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.aload_tool("my-tool-name", auth_tokens={"my_auth": get_auth_token})

# for a toolset use: 
authorized_tools = await toolbox.aload_toolset("my-toolset-name", auth_tokens={"my_auth": get_auth_token})

Specifying tokens for existing tools

• LangChain

tools = await toolbox.aload_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,
})
