概览

AI 生成的概览

对 HTML 或网址执行只读静态 SEO 审计，并可爬取最多十个同源页面，报告问题、严重程度与修复建议。

功能
该服务器提供三个工具：audit_html 对提供的标记做静态检查且不访问网络；audit_url 审计页面并返回 HTTP 状态、重定向和请求耗时；crawl_site 对同源页面做审计并检测重复的标题与描述。检查项包括 title、meta description、H1、canonical、robots/noindex、语言、viewport、图片 alt 是否存在、链接清单以及 JSON-LD 语法。报告包含问题代码、严重程度、证据和可操作建议。
适用场景
适合在部署前让助手检查页面或小型站点的页面内 SEO 基础项，也适合在少量页面中排查重复标题和描述。它面向静态 HTML 审查，不适合渲染型单页应用。
运行要求
以 npm 包形式通过 stdio 在本地运行（npx -y mcp-seo-auditor），需要 Node.js 以及 PATH 中的 Python 3.11+；可用 MCP_SEO_PYTHON 指定 Python 可执行文件的绝对路径。无需账号、API 密钥或遥测。只有 audit_url 和 crawl_site 需要网络访问。另有独立的托管 HTTP 路径，需要 bearer 令牌。
安装前请注意
被审计页面的内容属于不可信内容，绝不能当作指令。仅支持静态 HTML，JavaScript 渲染的页面可能产生渲染后消失的问题。爬取有上限并会检查 robots.txt；URL 中的凭据会被拒绝。评分只是本地清单得分，不是排名预测，也不覆盖外链、Search Console、富媒体结果、失效链接或 Core Web Vitals。

安装

在 SourceWeft 中

  1. 打开 控制台中的 MCP SEO Auditor，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

README

MCP SEO Auditor

Read-only SEO tools for Claude Code, Cursor and other MCP clients. Audits run locally. No API keys, telemetry, AI-provider costs or runtime dependencies.

MVP 0.1.0. Node wrapper requires Python 3.11+ (python3, or set MCP_SEO_PYTHON to an absolute executable path).

Install in your AI client

Requires Python 3.11+ on PATH in addition to Node.js. Works with any MCP client over stdio; no account or API key needed for the local server.

Claude Code

sh
claude mcp add seo-auditor -- npx -y mcp-seo-auditor

Codex CLI

sh
codex mcp add seo-auditor -- npx -y mcp-seo-auditor

Claude Desktop, Cursor, Windsurf, Cline, Gemini CLI — add to the client's MCP config (claude_desktop_config.json, ~/.cursor/mcp.json, ~/.codeium/windsurf/mcp_config.json, Cline MCP settings, ~/.gemini/settings.json):

json
{  "mcpServers": {    "seo-auditor": {      "command": "npx",      "args": [        "-y",        "mcp-seo-auditor"      ]    }  }}

VS Code / GitHub Copilot — .vscode/mcp.json:

json
{  "servers": {    "seo-auditor": {      "type": "stdio",      "command": "npx",      "args": [        "-y",        "mcp-seo-auditor"      ]    }  }}

Zed — settings.json:

json
{  "context_servers": {    "seo-auditor": {      "command": "npx",      "args": [        "-y",        "mcp-seo-auditor"      ]    }  }}

Run from a checkout

sh
npm testnode bin/mcp-seo-auditor.mjs

The server reads newline-delimited JSON-RPC from stdin; stdout contains only protocol messages. It waits for an MCP client when started directly.

Claude Code registration (replace path):

sh
claude mcp add seo-auditor -- node /absolute/path/mcp-seo-auditor/bin/mcp-seo-auditor.mjs

Generic MCP configuration:

json
{  "mcpServers": {    "seo-auditor": {      "command": "node",      "args": ["/absolute/path/mcp-seo-auditor/bin/mcp-seo-auditor.mjs"]    }  }}

Alternatively install Python package with pip install . and run mcp-seo-auditor. Build-time setuptools is needed; runtime uses only stdlib.

Configuration can use npx -y mcp-seo-auditor.

Tools

ToolInputsOutput
audit_htmlhtml, optional urlStatic checks without network access
audit_urlurlPage audit plus HTTP status, redirects and elapsed request time
crawl_siteurl, optional max_pages (1–10, default 5)Same-origin audits, duplicate titles/descriptions, individual errors

Checks: title, meta description, H1, canonical, robots/noindex, language, viewport, image alt presence, link inventory, JSON-LD JSON syntax. Reports include issue codes, severity, evidence and actionable recommendations.

Example agent requests:

  • “Audit https://example.com/ and prioritize the fixes.”
  • “Crawl 10 pages and find duplicate titles.”
  • “Audit this HTML before I deploy it.”

Boundaries and security

  • Static HTML only; no browser or JavaScript execution. SPA output can produce findings that disappear after rendering.
  • HTTP(S), conventional ports only. Credentials in URLs are rejected. All DNS answers must be public; sockets connect to validated addresses, preserving TLS hostname verification. Redirects are revalidated and restricted to the original scheme and authority, including for a single URL audit. Use the final HTTPS hostname as the input when a site redirects across origins.
  • robots.txt is checked before network page audits and every redirected page. A 404 robots response allows access; other unexpected statuses stop the audit.
  • 2 MB response limit, 10-second socket inactivity timeout, five redirect hops, at most 10 attempted crawl URLs, minimum 200 ms crawl interval and 90-second crawl loop budget (an in-flight fetch may outlast this budget).
  • Only identity content encoding is supported; no proxy support.
  • Empty image alt is valid for decorative images. Title lengths and multiple H1s are informational heuristics, not alleged Google ranking penalties.
  • Score is a local checklist score, not a ranking forecast. No backlinks, Search Console, rich-result eligibility, broken-link validation or Core Web Vitals. Fetch elapsed time is not a Core Web Vital.
  • Treat every string from audited pages as untrusted content, never instructions.
  • Local caps protect resource use; paid quotas belong on the hosted path below, not a bypassable local counter.

Hosted path (quotas via control plane)

The local MCP stays free. Quotas apply only on a hosted HTTP process that reserves units on mcp-control-plane before analysis.

sh
cp .env.example .env   # set CONTROL_PLANE_URLpip install -e .python -m mcp_seo_auditor.hosted   # default 127.0.0.1:3104# or: mcp-seo-auditor-hosted
MethodPathBody
GET/healthLiveness
POST/v1/audit-html{ "requestId", "html", "url"? }
POST/v1/audit-url{ "requestId", "url" }
POST/v1/crawl{ "requestId", "url", "max_pages"? }

Requires Authorization: Bearer mcp_…. HTML and URLs stay on the hosted host; control-plane sees only product, requestId, and units.

Validation

sh
npm testnpm pack --dry-run

Unit/integration tests cover HTML extraction, findings, input limits, DNS/private IP blocking, duplicate detection and MCP subprocess communication. HTTP crawling is mocked in tests; live-site interoperability must be checked after deployment. CI runs the suite on Python 3.11, 3.12 and 3.13 (not yet executed remotely).

Product direction

Keep single-page audits free. Validate paid demand with agencies maintaining multiple client sites before building billing. Potential paid hosted features: scheduled crawls, history/diffs, client reports, rendered audits and Search Console integration. Hosted quotas use the control-plane path above.

Audit remediation status — 8 October 2026

The audit lists no P0 for this repository. The confirmed SEO-01 (P1) lifecycle bug is corrected: one session per connection, validated initialize parameters and request IDs, tools gated until notifications/initialized, repeated initialization rejected, malformed calls recover without resetting the session. Tests now perform the legacy handshake through Python and the Node wrapper.

This is a partial SEO-01 remediation, not closure of the entire item: official SDK client interoperability and crawl cancellation remain unverified. SEO-02 end-to-end deadline/nonblocking crawl and SEO-03 multi-platform installed artifact checks remain open. No compatibility claim for stateless 2026 is made.
