hosted-tools-web-search

Use WebSearchTool, FileSearchTool, or CodeInterpreterTool from agents package. These run on OpenAI's servers without your Python code handling the execution.

When to apply

When you need real-time web search, vector store retrieval, or sandboxed code execution without building and maintaining tool infrastructure.

Web search

from agents import Agent, Runner, WebSearchTool

agent = Agent(
    name="Web searcher",
    instructions="You are a helpful agent.",
    tools=[WebSearchTool(
        user_location={"type": "approximate", "city": "New York"},
        search_context_size="medium",  # "low" | "medium" | "high"
    )],
)
result = await Runner.run(agent, "What's the latest local sports news?")

File search (vector store)

from agents import Agent, FileSearchTool

agent = Agent(
    name="Research assistant",
    tools=[FileSearchTool(
        max_num_results=3,
        vector_store_ids=["vs_abc123"],
    )],
)

Code interpreter

from agents import Agent, CodeInterpreterTool

agent = Agent(
    name="Data analyst",
    model="gpt-4o",
    instructions="Use the code interpreter to solve numeric problems.",
    tools=[CodeInterpreterTool(
        tool_config={"type": "code_interpreter", "container": {"type": "auto"}},
    )],
)

Key notes

Hosted tools run server-side; your Python process is NOT called for each tool invocation
on_tool_start/end lifecycle hooks do NOT fire for hosted tools
WebSearchTool supports filters for domain inclusion/exclusion
FileSearchTool supports ranking_options and include_search_results
CodeInterpreterTool requires org verification for gpt-5 class models with streaming
