Phoenix Playground and the Prompts library now support provider tools — built-in, vendor-hosted capabilities like web search, code execution, computer use, and grounding. Paste any provider’s tool JSON into the Playground and Phoenix stores and round-trips it verbatim, so your prompt runs against the underlying provider exactly as defined.
Provider tools sit alongside Phoenix’s existing portable function tools: function tools stay normalized and provider-agnostic; provider tools preserve provider-specific JSON for capabilities only that vendor offers.
What Phoenix forwards
Phoenix doesn’t maintain a hardcoded list of supported provider tools — anything the
underlying provider SDK accepts is round-tripped as-is. Examples that have been verified
end-to-end against the playground:
| Provider | Examples verified in Phoenix |
|---|
| Anthropic | web_search, code_execution, computer_use |
| OpenAI Responses API | web_search, file_search, code_interpreter, computer_use_preview, tool_search |
| Google Gemini | google_search grounding |
| Amazon Bedrock | provider-specific tool blocks are forwarded verbatim |
SDK prompt export
Both the Python and TypeScript clients preserve provider tools when exporting prompts:
from phoenix.client import Client
client = Client()
prompt = client.prompts.get(name="my-research-prompt")
# Provider tools are included in the formatted prompt
openai_messages = prompt.format(formatter="openai")
# openai_messages["tools"] contains both function tools and provider tools
import { getPrompt } from "@arizeai/phoenix-client/prompts";
const prompt = await getPrompt({ name: "my-research-prompt" });
const formatted = prompt.format({ formatter: "openai" });
// formatted.tools includes provider tools verbatim
