Using Tool Variables

You can use tool variables to specify environment variables available to your custom tools. For example, if you set a tool variable PASSWORD to banana, then write a custom function that prints os.getenv('PASSWORD') in the tool, the function will print banana.

To assign tool variables in the ADE, simply click on Variables to open the Tool Variables viewer:

You can also assign tool variables on agent creation in the API with the tool_exec_environment_variables parameter:

1
curl -X POST http://localhost:8283/v1/agents/ \
2
     -H "Content-Type: application/json" \
3
     -d '{

  "memory_blocks": [],

  "llm":"openai/gpt-4o-mini",
6
  "embedding":"openai/text-embedding-3-small",
7
  "tool_exec_environment_variables": {

      "COMPOSIO_ENTITY": "banana"
