About agent-client-protocol

from the package's own PyPI description — quoted content, verbatim

Agent Client Protocol (Python)

Build ACP-compliant agents and clients in Python with generated schema models, asyncio transports, helper builders, and runnable demos.

> Releases track the upstream ACP schema; contributions that tighten coverage or tooling are always welcome.

Install

pip install agent-client-protocol
# or
uv add agent-client-protocol

At a glance

Spec parity: Generated Pydantic models in acp.schema track every ACP release so payloads stay valid.
Runtime ergonomics: Async base classes, stdio JSON-RPC plumbing, and lifecycle helpers keep custom agents tiny.
Examples ready: Streaming, permissions, Gemini bridge, and duet demos live under examples/.
Helper builders: acp.helpers mirrors the Go/TS SDK APIs for content blocks, tool calls, and session updates.
Contrib utilities: Session accumulators, tool call trackers, and permission brokers share patterns from real deployments.

Who benefits

Agent authors who need typed models, helper builders, and event-stream ergonomics...

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Build ACP-compliant agents and clients in Python with generated Pydantic schema models, asyncio transports, and helper builders.

Low friction: single runtime dependency on pydantic, pure-Python wheel distribution, and active maintenance with a release 12 days ago.

Usage

pip install agent-client-protocol

import asyncio

# See examples/ directory in repository for runnable agent and client patterns

Python 3.10–3.14 required; asyncio event loop context needed.

Verdict: A well-maintained, actively developed SDK for the Agent Client Protocol with minimal dependencies and no known vulnerabilities. License status is unclear and should be verified before use in proprietary contexts.

Needs verification

Confirm the license under which agent-client-protocol is distributed (license_raw and license_spdx are both null).
