# Boundary & Risk Card

Project: modelcontextprotocol/python-sdk

## Doramagic Trial Decision

Current decision: it can enter pre-publication recommendation checks. First use should still start with least privilege, a temporary directory, and reversible configuration.

## What The User Can Do Now

- Read the Human Manual first to understand the project purpose and main workflows.
- Use Prompt Preview for pre-install exploration; it validates interaction shape, not real execution.
- Run official Quick Start commands only inside an isolated environment, not a primary setup.

## Do Not Do Yet

- Do not treat Prompt Preview as a real project execution result.
- Do not treat metadata-only validation as sandbox installation validation.
- Do not describe unverified capabilities as supported, working, or safe to install.
- Do not provide production data, private files, real secrets, or primary host configuration on first trial.

## Pre-Install Checklist

- Host AI match: local_cli
- Official installation entry status: official entry point found
- Isolated temporary directory, temporary host, or container validation: required
- Configuration rollback path: required
- API keys, network access, file access, or host configuration changes: treat as high risk until confirmed
- Installation command, actual output, and failure logs: must be recorded

## Current Blockers

- No blockers.

## Project-Specific Pitfalls

- 来源证据：Duplicate `initialize` with changed parameters can overwrite `ServerSession.client_params` (high): 可能增加新用户试用和生产接入成本。 Suggested check: 来源问题仍为 open，Pack Agent 需要复核是否仍影响当前版本。
- 来源证据：Streamable HTTP server silently drops in-flight request when client reuses a JSON-RPC id (high): 可能增加新用户试用和生产接入成本。 Suggested check: 来源问题仍为 open，Pack Agent 需要复核是否仍影响当前版本。
- 来源证据：streamable_http_client: one concurrent request HTTPStatusError tears down sibling requests (high): 可能增加新用户试用和生产接入成本。 Suggested check: 来源问题仍为 open，Pack Agent 需要复核是否仍影响当前版本。
- 来源证据：FastMCP crashes when tool return type uses Python 3.10+ `A | B | C` union syntax (high): 可能阻塞安装或首次运行。 Suggested check: 来源问题仍为 open，Pack Agent 需要复核是否仍影响当前版本。
- 来源证据：Feature Proposal: Secure Tool/Resource/Prompt Decorators with Auth + Encrypted I/O (high): 可能影响授权、密钥配置或安全边界。 Suggested check: 来源问题仍为 open，Pack Agent 需要复核是否仍影响当前版本。
