Callers cannot inject generation params (temperature, instructions, tools, …) unless the host explicitly allows it. - A custom run_hook replaces the default entirely and receives the full ChannelRequest.options plus the raw protocol_request. - Update tests to cover remap, default-strip, and custom-hook paths. - Clarify host debug-log docstring to match new option flow.

Multi-channel hosting samples
End-to-end samples for serving an agent-framework agent (or workflow)
through one or more channels with agent-framework-hosting.
The general hosting plumbing lives in
agent-framework-hosting; each channel is
its own package. This first sample set includes
agent-framework-hosting-responses.
| Sample | What it shows | Packaging |
|---|---|---|
local_responses/ |
The minimal shape: one agent + one @tool + ResponsesChannel + a single run_hook that strips caller-supplied options and forces a reasoning preset. |
Local only. Start here to learn the run-hook seam. |
local_responses_workflow/ |
A 4-step Workflow (typed SloganBrief intake → writer → legal → formatter) hosted behind the Responses channel via a run_hook that parses inbound text/JSON into the workflow's typed input. The host writes per-conversation checkpoints via checkpoint_location=…. Demonstrates workflow targets + structured input adaptation + resume-across-turns. Includes a call_server.rest file with REST examples. |
Local only. |
Each sample is fully self-contained — its own pyproject.toml, uv.lock,
server app.py, calling script(s), and storage/ directory. Every
sample uses [tool.uv.sources] to wire its agent-framework-hosting*
dependencies to the
main
branch of the upstream repo via git refs, so they install cleanly outside
the monorepo while the hosting packages are still pre-PyPI. Once those
packages publish, drop the [tool.uv.sources] block and let the
declared deps resolve from PyPI.
Relationship to ../foundry-hosted-agents/
The sibling ../foundry-hosted-agents/ directory
contains samples for the agent-framework-hosted stack — agents
that run inside the Foundry Hosted Agents platform using its
built-in protocol surface (Responses, Invocations, conversation store,
isolation, identity), with no agent-framework-hosting package
involved.
| Aspect | af-hosting/ (this directory) |
foundry-hosted-agents/ |
|---|---|---|
| Server stack | agent-framework-hosting + agent-framework-hosting-responses |
agent-framework-hosted only — the Foundry Hosted Agents runtime owns the HTTP surface |
| Channels | Responses only in this initial sample set | The platform exposes Responses + Invocations |
| Run target | Local Hypercorn (local_responses/, local_responses_workflow/) |
Hosted Agents or local container; targets the Hosted Agents platform contract |
| When to pick this | You want to learn the host/channel seams locally or need custom hosting middleware | You want zero hosting boilerplate, leveraging the Foundry-managed surface |
The table above summarizes the cross-sample story.
