feat(mcp): add a source allowlist for the MCP server endpoint

Restrict which source addresses may call /mcp with a list of IPs/CIDRs
(IPv4 and IPv6). The check runs before token authentication, so a source
that is not listed is refused with 403 even when it holds a valid token.
An empty list keeps the previous behaviour (any source).

Behind a reverse proxy the TCP peer is always the proxy, so proxies can be
registered as trusted: for requests from them the client is the rightmost
X-Forwarded-For hop that is not itself a trusted proxy. Without a trusted
proxy the header is ignored, so a caller cannot claim an allowed address.

- A stored configuration that cannot be read or parsed refuses requests
  instead of falling back to no restriction.
- The audit log records the resolved client address.
- The settings API reports the address the server sees for the caller.
- The allowlist applies to /mcp only; the web UI and admin API are
  unaffected.

 ## [Unreleased]
 
+- 新增 MCP 服务端：在「系统设置 → MCP 服务端」开启后，外部智能体可通过 `/mcp`（Streamable HTTP）查看任务与漏洞、创建任务、暂停/恢复任务、补充提示。新增访问令牌（权限范围、限定企业、任务限额、有效期、吊销）与调用审计。支持来源白名单（IP/CIDR，可配置可信反向代理），在令牌校验之前生效。默认关闭；`/mcp` 只认访问令牌，不经过也无法使用 HTTP Basic Auth。详见 README「MCP 服务端」。
 - 新增可选「无成果止损」：按实际运行时长、独立漏洞数量与最低等级做一次检查，未达标时自动收尾并显示「无成果停止」；暂停、排队及计划窗口外不计时，复活后重新计时，默认关闭。停止状态复用 `timeout`，已有 `on_task_timeout` 触发器仍会执行并可能消耗 token。

+### MCP 服务端（供外部智能体编排任务）
+
+ARTEX 可以作为 MCP 服务端，让外部智能体（个人助手、bot 等）查看任务与漏洞、创建任务、暂停或恢复任务。
+
+注意区分：「系统 → MCP」页面管理的是 ARTEX 自己的 agent **去调用**的外部 MCP；本文说的是 ARTEX **对外提供**的 MCP 端点。
+
+#### 开启与接入
+
+1. 「系统设置 → 系统与账号 → MCP 服务端」打开开关。默认关闭，关闭时 `/mcp` 返回 404。
+2. 在同一处「新建令牌」，选择权限范围。令牌只显示一次。
+3. 在智能体里配置：
+
+| 项 | 值 |
+| --- | --- |
+| 地址 | `https://<你的 ARTEX 地址>/mcp` |
+| 传输 | Streamable HTTP（无状态，只响应 `application/json`，不提供 SSE，不支持 stdio） |
+| 鉴权 | 请求头 `Authorization: Bearer artex_mcp_...` |
+
+```bash
+curl -s https://artex.example.com/mcp \
+  -H 'Authorization: Bearer artex_mcp_xxx' -H 'Content-Type: application/json' \
+  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
+```
+
+#### 无法使用 HTTP Basic Auth
+
+`/mcp` **不经过** HTTP Basic Auth 验证，也**不接受** Basic 账号密码、ARTEX 登录密码或管理员登录后的 JWT，只认访问令牌。
+
+原因：一个 HTTP 请求只有一个 `Authorization` 头，外部智能体无法同时带上 Basic 凭证和 Bearer 令牌。因此：
+
+- 即使启用了 HTTP Basic Auth，`/mcp` 仍可直接凭访问令牌访问，Basic Auth 不会给它加一层保护。
+- 需要限制谁能连 `/mcp` 的话，请用下文的「来源白名单」，不要依赖 Basic Auth。
+- 公网暴露请使用 HTTPS，令牌是明文放在请求头里的。
+
+#### 来源白名单
+
+在「MCP 服务端」卡片的「来源白名单」里填写允许调用 `/mcp` 的来源地址，每行一个 IP 或 CIDR（如 `203.0.113.7`、`10.0.0.0/8`，支持 IPv6）。留空表示不限制来源。
+
+- 白名单在令牌之前检查：不在名单内的来源即使持有有效令牌也会被拒绝，返回 `403`，响应里带有服务器看到的来源地址，便于排查。
+- 白名单只作用于 `/mcp`，不影响网页和管理 API，填错不会把自己锁在后台之外。
+- **部署在反向代理之后**：此时直连地址永远是代理。需要把代理地址填进「可信代理」，ARTEX 才会改用 `X-Forwarded-For` 里的地址作为来源（从右往左取第一个不属于可信代理的地址）。不填可信代理时该请求头一律忽略，避免调用方伪造来源。代理需要把真实来源追加到该请求头，例如 nginx 的 `proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;`。
+- 卡片里会显示「服务器看到的你当前的来源地址」，可用来确认可信代理是否配置正确。
+
+#### 权限范围与工具
+
+令牌只能看到、调用它的权限范围内的工具。
+
+| 权限范围 | 工具 | 说明 |
+| --- | --- | --- |
+| `read` | `list_tasks` | 列出任务，可按 `company_id`、`category_id`、`status` 筛选 |
+| `read` | `get_task` | 单个任务的状态、运行时长、目标完成数、漏洞数；用它轮询进度 |
+| `read` | `get_task_graph` | 任务的探索图总览 |
+| `read` | `list_task_findings` | 任务的确认漏洞（不含原始请求/响应流量） |
+| `read` | `list_companies` / `list_task_categories` / `list_llm_profiles` | 建任务时可选的企业、分类、模型配置（不含 API Key） |
+| `task:create` | `spawn_task` | 新建并启动任务，可带 `company_ids`、`category_id` |
+| `task:control` | `pause_task` / `resume_task` / `add_task_hint` | 暂停、恢复、补充提示 |
+
+ARTEX 没有独立的「项目」实体。智能体说的“某个项目”对应某个企业或某个任务分类下的一组任务。
+
+不会暴露的能力：建/改自定义工具、MCP、skill，workspace 文件读写，LLM 密钥，系统设置。
+
+#### 令牌的限制项
+
+- **限定企业**：勾选后，令牌只能在这些企业下建任务（必须带 `company_ids`，且目标地址须归属这些企业的范围），也只能看到、控制这些企业下的任务，其余任务对它表现为不存在。这是把任务绑定到企业的资产范围，不是网络层拦截；要硬性限制任务能访问什么，请配合资产拦截规则。
+- **未结束任务上限**：该令牌创建的、尚未结束的任务数（含暂停和排队）。
+- **每小时建任务上限**：按该令牌过去一小时创建的任务数计，任务删除后仍计入。
+- **有效期**与**吊销**：吊销立即生效，不可恢复。
+
+#### 审计
+
+每次工具调用都会记录：令牌、工具、参数、是否成功、失败原因、来源地址、时间，包括因权限不足被拒绝的调用。在设置页的「调用审计」查看，保留最近 20000 条。
+
+#### 安全提示
+
+- 创建任务会对目标发起真实的安全测试，只把 `task:create` 令牌交给可信的智能体，并尽量限定企业、设置限额。
+- 任务描述、漏洞摘要等返回内容可能包含来自被测目标的文本，对智能体而言是不可信输入，可能夹带提示注入。
+- 带 `Origin` 头的跨源浏览器请求会被拒绝（403），`/mcp` 不发送 CORS 头。
+
 ### 反向代理部署（HTTPS / 只开放 443）
 
 前端和 API/SSE 都由同一个后端端口（默认 `:8787`）提供，实时活动流默认走**同源**地址，因此**无需配置 `NEXT_PUBLIC_SSE_BASE`**，公网只开放 443、把 8787 留在内网即可。
