模型上下文协议

Your AI client asks. Its partner inside your network does the heavy lifting.

Your 网络代理 now does the measuring, profiling, holding and analyzing where your data lives: the heavy, repetitive, context-eating work your AI client, or Nova, used to do one fetch at a time. Now it walks into every question with the cheat sheet already written and spends its attention on the thinking. It works from claude.ai, ChatGPT, Cursor and any MCP client.

The Analytic toolset

What your AI client can do now

Every ability below runs through your Network Agent. Abilities marked Personal Core and up 或 Business Core and up need that plan. Everything else works on every plan, Free included.

Map your data

Every plan
  • See every connector and Network Agent in your account, and whether each one is online.
  • Explore a large database level by level: business areas, then tables, then compact column lists, then full detail. Personal Core and up
  • Get one table’s columns, keys, allowed values and descriptions in a single answer.
  • See how tables join, and read per-column profiles: sample values, distributions and what each column means.
工具 qs_list_connectors qs_get_connector_schema qs_get_table_schema qs_get_relationships qs_profile_table

Context management

Personal Core and up
Answers sized to what your AI client can read.
  • Shape a result before reading it: the estimated row count, the token cost of the whole result and how many rows fit, before anything is sent.
  • Size the answer to the AI’s budget: only the columns it needs, empty columns dropped. Whole rows are kept, and anything left out is reported.
  • Long text is trimmed with a marker, and the full value is one call away.
工具 qs_run_query · shape qs_run_query · columns schema levels

Result analysis

Personal Core and up
Keep a result on your Network Agent and keep asking.
  • Ask for a profile instead of rows: counts, empty values, distinct values, ranges and the most common values for every column, from one pass.
  • Follow up on a held result with no second database query. Filter it, group it, sort it, join two held results, or run your own SQL over it.
  • Page through it, take a repeatable sample, or re-run a question and get only the rows that changed since last time.
工具 qs_run_query · profile qs_run_query · hold qs_result_query qs_result_page qs_result_sample qs_data_freshness changed since qs_result_windows qs_result_release

Deeper analysis

Business Core and up
Computed by your Network Agent over a held result. Each answer comes with a one-sentence summary.
  • Data-quality report. Empty and blank rates, format consistency, duplicate keys, outliers and a leading-digit check on amounts, ranked by severity.
  • Anomalies. Spikes and level changes in a value over time.
  • Segments. Natural groups of similar rows, each with its size and profile.
  • Compare. Whether two groups really differ, with the test used, its p-value and the size of the effect.
  • Diff. What was added, removed, changed and unchanged between two runs, with example keys.
工具 qs_run_query · quality qs_result_anomalies qs_result_segments qs_result_compare qs_result_diff

Queries, saved queries, federated queries and alerts

Every plan
  • Run any read-only query your AI client writes.
  • Run your organization’s saved queries by name, with your own parameter values.
  • Run federated queries that join several sources. They run on our side and come back already joined.
  • See your alert rules, their current state and recent deliveries.
  • Propose a new alert rule on a saved query. It stays in dry run and notifies nobody until a person arms it on the Alerts page.

Nova，查询流助手
或者完全跳过人工智能客户端。

认识一下 Nova。它是 Query Streams 中内置的助手。

Nova是 基于网络的用户无需安装任何软件，无需更新 Claude Desktop，也无需批准连接器。 无需购买 claude.ai 或 ChatGPT 订阅。 他们只需要一个 Query Streams 登录账号即可。用简单的英语提问；Nova 会根据您的语义智能模型生成并验证 SQL，然后通过同一个代理以只读方式运行该 SQL，将结果绘制成图表，并将其保存为查询，您的团队可以从 Excel、Google Sheets 或 REST API 中运行该查询。

  • The same Network Agent toolset your AI client gets over MCP, plus validated SQL, charts and saved queries
  • 只需给整个团队提供登录账号即可完成部署——仅此而已。
  • 商业计划书中包含的内容
认识诺瓦 如果您的用户已经在使用 Claude、Cursor 或 ChatGPT，请使用 MCP。如果您希望在 Portal 内获得答案，请使用 Nova。

为什么可以安全地将人工智能应用于生产数据

配置文件中的连接字符串永远无法提供以下三件事。

无需 VPN，通过任何网络

网络代理打开一个加密连接 出去 这样，公司办公室的数据库和家里的 AI 客户端就可以连接到云端，而无需入站端口、IP 允许列表和 VPN——这是安全团队已经认可的模式。

语义智能，而非 信息模式

每次模式调用都会返回 AI 整理的描述、每列的语义类型、示例值、枚举分布和发现的外键——因此该模型第一次就能编写正确的 SQL，而不是靠猜测。

只读且按键作用域

代理中硬编码的验证器仅允许 选择 / 和 / 解释 其他所有操作都会被拒绝。每个键都有自己的作用域，因此仅供浏览的键永远不会被执行。

You stay in control

You decide what reaches your AI client

The Context tab on the MCP page tunes what your AI client receives, for your organization and for each key. Turn on Apply to Nova and Nova follows the same result rules.

Text cell limit

Long text never floods the answer

Long values are cut to the length you set, with a marker showing how much was left out. The full value is one call away.

Personal Core and up
Schema view for large databases

A big database arrives as a map

Choose what your AI client gets first: a table list by business area, a compact column list or full detail.

Personal Core and up
Result size

Results sized for your AI client

Auto sizes each result for the AI client in use. A fixed size keeps every result under the token budget you set.

Personal Core and up
Deeper analysis

Analysis defaults you set

Pick which analyses your AI client can run, and set anomaly sensitivity, the most groups and comparison confidence. A request can adjust them within these limits.

Business Core and up
Read-only, enforced on your Network Agent. Only SELECT, WITH and EXPLAIN run.
Scopes per key. A key can be limited to specific connectors. Revoke any key or connected app in one click.
Every call is logged on the MCP Activity tab.
Local analysis, per agent. On the Data Agents page, turn held results on or off, set their budget and hold time, or clear them in one click.
Set it once for your organization, then per key where a team needs something different. Open the Context tab

IT部门只需安装一次代理程序。之后，连接助手只需在聊天应用中登录，或在开发者工具中大约90秒即可完成。

01

安装代理程序

在您的网络内部（Windows、Linux 或 macOS）部署一个小型、仅支持出站流量的服务。由数据库管理员一次性配置。无需入站端口，也无需 VPN。

02

添加您的来源

任何 11 数据库和 8 API 连接器。语义智能分析这些连接器，使 AI 能够识别真实的列，而不是猜测。

03

联系并提问

Connect an AI client on the MCP page opens a short wizard: how it connects, pick your client, set it up, check the connection. Chat apps approve from the app with no key, and developer tools get a key made for them. Then ask.

对于开发者

它的运作原理，如果您想了解详情的话。

以上所有内容无需阅读本部分即可完成。本部分内容是为负责配置 Cursor 或 Claude Code，或者需要向安全部门解释为什么 AI 可以查询生产环境的人员准备的。

引擎盖下

您的AI配置中没有数据库凭证。没有使用VPN。

聊天应用根本不需要密钥——它们都是通过登录完成的。开发者工具则需要一个可撤销的密钥。 MCP密钥这就是配置中需要包含的全部内容。开源 MCP 则会在此处放置原始连接字符串，因此 AI（以及您的笔记本电脑）必须直接访问数据库。而使用查询流时，真正的凭据则存储在网络代理上。 里面 您的网络允许家中的 AI 客户端安全地访问公司办公室的数据库，无需 VPN，也不会暴露任何信息。

Why the Network Agent makes the difference

Most database connectors for AI hand the model a fixed set of record operations, or raw rows, and need a reachable endpoint into your network.

CompareA typical database connector for AIQuery Streams, with a Network Agent
Reaching the dataAn endpoint the AI must be able to reach inside your networkOne outbound connection, nothing to open in your firewall. No inbound port, no VPN
In the configA raw connection string, with whatever access it grantsA sign-in for chat apps, or one revocable key with its own 读 / 分析 / 执行 范围
What comes backA fixed set of record operations, or raw rowsThe AI writes real SQL, and the agent reads the whole result next to your data and sends back what fits
Follow-upsEvery follow-up is another database callA held result answers follow-ups with no second database query Personal Core and up

Faster because nothing crosses the wire that does not need to. Safer because the rows stay home.

MCP 服务器常见问题解答

我需要开放端口还是运行 VPN？

不。网络代理运行在您的网络内部，并打开一个单独的出站加密连接。 mcp.querystreams.com 请求和结果通过代理发起的单一通道双向传输。您的 AI 客户端连接到云端，而非数据库，因此无需入站端口、静态 IP 地址白名单或 VPN。这使得公司办公室的数据库能够响应家中 AI 客户端的请求。代理可以运行在笔记本电脑、虚拟机、本地硬件或任何允许出站 HTTPS 的云平台上。

我的数据库凭据是否已添加到 AI 配置中？

不。客户端配置中只需要一个可撤销的 MCP 密钥（令牌）和云端 URL。您的 AI 客户端绝不会保存数据库登录信息。查询在您网络内部的网络代理上运行；只有加密的请求和结果会通过查询流传输，并且不会存储任何数据。您可以随时通过门户撤销密钥。

Does my AI client see my rows?

Only what fits, and only what it asks for. Your Network Agent reads the whole result next to your data, inside your network. Only the answer and the rows a user asks to see are sent back, sized to what your AI client can read. A shape, a profile or an analysis sends a summary instead of rows, and the rows stay home.

What is a held result?

A result your AI client asks to keep. Your Network Agent holds the complete result inside your network for a limited time, so follow-up questions are answered from it with no second database query: filter it, group it, sort it, join two held results, page through it or take a sample. Query Streams’ servers never store those rows. A held result is released when its hold time ends, when your AI client releases it, or when someone clicks Clear held results on the Data Agents page. Held results are part of Result analysis, on Personal Core and up.

我的用户需要订阅Claude或ChatGPT吗？

只有当他们想通过这些应用程序提问时。 诺瓦Query Streams 内置了助手，任何人只需登录 Query Streams 即可使用：它是基于 Web 的，无需安装任何软件，也无需购买或管理第三方 AI 帐户。

需要安装什么吗？

只需安装一次：网络代理，一个运行在网络内部、数据库旁边的小型服务。AI 端无需安装任何软件。claude.ai 和 ChatGPT 通过登录连接；开发者工具只需一个密钥。

我可以使用哪些人工智能工具？

任何兼容 MCP 的客户端。已使用 Claude Desktop、Claude Code、Cursor、ChatGPT、Grok、Windsurf、Zed、Gemini CLI、Continue、VS Code Copilot 和 Goose 进行测试——并且适用于任何其他兼容 MCP 的客户端。

如果人工智能试图写入或删除数据会怎样？

网络代理会在每个查询到达数据库之前，先通过硬编码的只读验证器对每个查询进行验证。 选择, 和 和 解释 都被接受；其他一切（插入, 更新, 删除, 降低, 改变……）被拒绝。验证器运行在代理程序中，而不是云端，因此即使云端环境遭到入侵，也无法绕过它。

哪些套餐包含MCP服务器？

Every plan, including Free, and the Free plan never expires. Free gives one key, 30 calls a minute and up to 1,000 rows per query. Paid plans add keys, calls a minute and rows per query: 2,500 on Personal Core, 5,000 on Personal Plus, 10,000 on Business Core, 25,000 on Business Plus, 50,000 on Business Max and 100,000 on Enterprise. A year of daily sales for 20 stores (7,300 rows) comes back to your AI client in one query from Business Core up. Nova, the assistant built into the Portal, is included on Business and Enterprise plans. 比较方案.

Which plans include the Analytic toolset?

Personal Core and Personal Plus include Context management and Result analysis, with held results of up to 128 MB per agent, held for up to 15 minutes. Business Core, Plus and Max add Deeper analysis, with held results of up to 512 MB for up to 60 minutes. 企业版 holds larger results for longer: up to 4,096 MB per agent, held for up to 8 hours. The Free plan has standard results. 比较方案.

Does this change the Free plan?

No. The Free plan works as it always has: MCP, the REST API, federated queries and alerts, with the same results as before. Your keys and connected apps keep working as they are, with nothing to reconnect. Paid plans add the Analytic toolset on top.

Ask your AI client about your biggest table.

Connect claude.ai, ChatGPT, Cursor or any MCP client: one click for chat apps, one key for developer tools. Or give your team Nova and skip the AI client altogether.
