Capabilities and conditions
- 官网称 ContextStream 把托管代码搜索与保存的项目知识（决策、经验、偏好、洞察、计划）结合，通过 MCP 把相关上下文推送给 Cursor、Claude Code、Codex、Grok 等客户端。 Source ↗
- 官网称其适用于多个 agent、多次会话、跨工具的重复性工作场景：agent 借助保存的决策与代码证据提出下一步，由人检查证据后决策；官网提醒这并不会让 agent 不犯错。 Source ↗
- 官网定价页：Starter $0/月、免信用卡，每月 10,000 credits、无试用期限；Pro $19/月每月 25,000 credits；Elite $49/月；Team $79/人/月；各档功能相同，仅 credits、项目数与人数不同。 Source ↗
- 官网 FAQ 明确指出：即使使用本地 MCP 连接，符合条件的代码文件内容仍会被发送到 ContextStream 做托管索引，建议索引前检查 .gitignore 与 .contextignore。 Source ↗
