purra-anthropic · Python
English | 简体中文
Anthropic Messages gateway for PurrA using the official Python SDK. Supports text, function tools, streaming, cancellation, and token usage. Requires Python 3.11+.
Install
From the repository root:
python -m pip install . ./integrations/anthropic/python
Configure
from anthropic import AsyncAnthropic
from purra_anthropic import AnthropicMessagesGateway
client = AsyncAnthropic()
gateway = AnthropicMessagesGateway(client, timeout_seconds=60)
Pass gateway to AgentCore(model_gateway=gateway, ...). In the Run's
ModelRequest, set provider="anthropic", the model ID, and its capability snapshot.
The application supplies credentials and verified model limits.
Model options
ModelRequest.options accepts max_tokens, temperature, top_p, top_k,
thinking, and output_config. Choose options supported by the selected model.
Enabled reasoning requires an explicit thinking configuration, such as
{"type": "adaptive"} on a supporting model. A manual budget_tokens must be
at least 1024 and below the resolved output limit. Forced tool choice cannot be
combined with enabled thinking.
Behavior
SDK retries are disabled; Core controls retry and budget accounting. The gateway applies Core's resolved output limit and combines system/developer instructions into Anthropic's system field.
Signed thinking and redacted blocks are retained as private continuation data. Keep them with the unchanged assistant message when continuing on the same model; they are excluded from public output. Input usage includes cache writes and reads.
Multimodal content, hosted tools, and beta APIs are not supported.
Other vendors require application adapters. Close a supplied SDK client in the
application; await gateway.close() only closes a client created by the gateway.
