CNKI Basic Search

Search CNKI for papers using keyword(s). Returns result count and structured result list (titles, URLs, authors, journal, date) in a single call.

Arguments

$ARGUMENTS contains the search keyword(s) in Chinese or English.

Steps

1. Navigate

Use mcp__chrome-devtools__navigate_page → https://kns.cnki.net/kns8s/search

2. Search + extract results (single evaluate_script, NO wait_for)

Replace YOUR_KEYWORDS with actual search terms:

async () => {
  const query = "YOUR_KEYWORDS";

  // Wait for search input (replaces wait_for)
  await new Promise((r, j) => {
    let n = 0;
    const c = () => { if (document.querySelector('input.search-input')) r(); else if (++n > 30) j('timeout'); else setTimeout(c, 500); };
    c();
  });

  // Check captcha (only if visible on screen, not hidden SDK at top:-1000000)
  const outer = document.querySelector('#tcaptcha_transform_dy');
  if (outer && outer.getBoundingClientRect().top >= 0) return { error: 'captcha' };

  // Fill and submit (verified selectors: input.search-input, input.search-btn)
  const input = document.querySelector('input.search-input');
  input.value = query;
  input.dispatchEvent(new Event('input', { bubbles: true }));
  document.querySelector('input.search-btn')?.click();

  // Wait for results
  await new Promise((r, j) => {
    let n = 0;
    const c = () => { if (document.body.innerText.includes('条结果')) r(); else if (++n > 30) j('timeout'); else setTimeout(c, 500); };
    c();
  });

  // Check captcha again
  const outer2 = document.querySelector('#tcaptcha_transform_dy');
  if (outer2 && outer2.getBoundingClientRect().top >= 0) return { error: 'captcha' };

  // Extract current page results (merged parse-results)
  const rows = document.querySelectorAll('.result-table-list tbody tr');
  const checkboxes = document.querySelectorAll('.result-table-list tbody input.cbItem');
  const results = Array.from(rows).map((row, i) => {
    const titleLink = row.querySelector('td.name a.fz14');
    const authors = Array.from(row.querySelectorAll('td.author a.KnowledgeNetLink') || []).map(a => a.innerText?.trim());
    const journal = row.querySelector('td.source a')?.innerText?.trim() || '';
    const date = row.querySelector('td.date')?.innerText?.trim() || '';
    const citations = row.querySelector('td.quote')?.innerText?.trim() || '';
    const downloads = row.querySelector('td.download')?.innerText?.trim() || '';
    return {
      n: i + 1,
      title: titleLink?.innerText?.trim() || '',
      href: titleLink?.href || '',
      exportId: checkboxes[i]?.value || '',
      authors: authors.join('; '),
      journal,
      date,
      citations,
      downloads
    };
  });

  return {
    query,
    total: document.querySelector('.pagerTitleCell')?.innerText?.match(/([\d,]+)/)?.[1] || '0',
    page: document.querySelector('.countPageMark')?.innerText || '1/1',
    results
  };
}

3. Report

Present results as a numbered list:

Searched CNKI for "$ARGUMENTS": found {total} results (page {page}).

1. {title}
   Authors: {authors} | Journal: {journal} | Date: {date}
   Citations: {citations} | Downloads: {downloads}

2. ...

4. Follow-up: navigate to a paper

When the user wants to open or download a specific paper, use navigate_page with the result's href URL directly — do NOT click the link (clicking opens a new tab and wastes 3 extra tool calls for tab management).

Captcha detection

Check #tcaptcha_transform_dy element's getBoundingClientRect().top >= 0. Tencent captcha SDK preloads DOM at top: -1000000px (off-screen, not active). Only return error: 'captcha' when top >= 0 (actually visible to user).

Verified selectors

| Element | Selector | Notes | |---------|----------|-------| | Search input | input.search-input | id=txt_search, placeholder "中文文献、外文文献" | | Search button | input.search-btn | type="button" | | Result count | .pagerTitleCell | text "共找到 X 条结果" | | Page indicator | .countPageMark | text "1/300" | | Result rows | .result-table-list tbody tr | Each row = one paper | | Title link | td.name a.fz14 | Paper title with href | | Authors | td.author a.KnowledgeNetLink | Author name links | | Journal | td.source a | Journal/source link | | Date | td.date | Publication date text | | Citations | td.quote | Citation count | | Downloads | td.download | Download count |

Batch export to Zotero

When user wants to save results to Zotero, use batch export directly from the results page — do NOT navigate to each detail page. The exportId in results equals the detail page's #export-id. Call cnki-export skill with batch mode (Step 1B). See cnki-export SKILL.md for details.
