@pipeworx/china-disclosures

Non-SEC Chinese biotech deals and HK/STAR IPO financing — licensing agreements and IPOs with no US-listed party, read straight out of the HKEX and CNINFO exchange disclosure feeds. Keyless.

Part of Pipeworx — an MCP gateway connecting AI agents to 1683+ live data sources.

Tools

• hkex_licensing_deals(query?, since?, until?, limit?) — biotech/pharma licensing and collaboration deals disclosed by HKEX-listed companies, including deals with no US-listed party at all (e.g. a Chinese HKEX-listed biotech out-licensing to an Indian, Japanese, or European partner). Sourced from HKEXnews filings titled "License Agreement" or "Licensing Agreement".
• hkex_ipo_filings(query?, since?, until?, limit?) — Hong Kong IPO / listing financing filings — the "GLOBAL OFFERING" prospectus and formal notice every company files with HKEX when it lists. Not biotech-specific; filter with query.
• cninfo_disclosure_search(query, board?, since?, until?, limit?) — full-text search over CNINFO, the official disclosure feed for both Chinese A-share exchanges (Shenzhen + Shanghai, STAR Market included). Covers A-share-listed companies with zero HK/US nexus — the other half of the gap.

Why this exists, and why china-pharma / pharma-deals don't already cover it

china_licensing_deals (china-pharma) and pharma_licensing_deals (pharma-deals) are both SEC 8-K based: they see a deal only if at least one party is US-listed. A China-to-China or China-to-Japan deal between two companies with no US listing is real, disclosed, and structurally invisible to either tool. Demand log, 2026-09-13 scouting pass: 3+ real asks for exactly that class of deal, plus HK/STAR biotech IPO financing.

Two more exchanges' own disclosure layers close the gap, both probed live 2026-09-13:

• HKEX — any Hong Kong-listed company discloses a material licensing deal or its own IPO under HKEX listing rules the same day, and HKEXnews' public title-search JSON endpoint (titleSearchServlet.do) serves those filings without a key. This is the same endpoint nmpa_drug_approvals (china-pharma) already uses for NMPA approvals — same trick, different title term.
• CNINFO (cninfo.com.cn) — the official disclosure feed for SZSE + SSE A-shares, STAR Market included. hisAnnouncement/query is a POST endpoint, no auth, plain browser UA — verified live returning 20,703 matches for searchkey=许可 (license/licence), dated as recent as the day of the probe.

Traps

• HKEX titleSearchServlet.do ignores from/to entirely when searchType=1 and title is set — verified across three different date windows (a 9-month range, a 1-month range, and a single day in 1990) on three different title terms ("License Agreement", "Licensing Agreement", "Global Offering"): identical result set every time. It is a rolling most-recent-titles window, not a date-filtered query. Both HKEX tools fetch the unbounded window and apply since/until themselves, client-side — a window before the reachable range returns found: false with an explicit hint naming the actual reachable dates, never a silently-empty "nothing that period".

• CNINFO's board/segment filter looks like it should be guessable and isn't. An initial probe of category=/plate=kcb for STAR Market returned HTTP 200 with the full unfiltered result set — a silent no-op, not an error. The real parameter, plate=shkcp, was found by watching the disclosure search page's OWN network request when its 科创板 (STAR Market) checkbox is selected in the browser — the same recipe china-exchange-data used for SZSE's report catalogs. Verified as a REAL filter, not another no-op: unfiltered searchkey=许可 returns totalAnnouncement: 20703; plate=shkcp returns 306, every one of them a 688xxx (STAR Market) code.

  Unfiltered vs. filtered, same search term, live 2026-09-13:

  Code

  Copy

  plate=""      (all SZSE+SSE)  → totalAnnouncement: 20703
  plate="shkcp" (STAR Market)   → totalAnnouncement: 306   (all secCode 688xxx)
  

  Only star (shkcp) and chinext (szcy) are exposed as board values — both confirmed the same way. Other segments (main board, GEM) were not observed this way and are deliberately left unmapped rather than guessed; omit board to search all boards.

• CNINFO's seDate range param genuinely filters server-side (unlike HKEX's from/to) — confirmed by comparing a 12-day window (1 hit) against a disjoint historical month (0 hits) for the identical search term and board.

• Don't translate a query before searching CNINFO. It is a Chinese full-text index; searching the English translation of a Chinese term returns nothing, and reads as "no disclosures" rather than "wrong language" (see reference_bilingual_entity_names — never translate-then-search).

• HKEX title search returns duplicate rows for one event. A Global Offering typically produces both a "Listing Documents" row (the prospectus PDF) and an "Announcements and Notices" row (the formal notice) for the same listing — both are returned, tagged with doc_category, rather than silently deduplicated into one.

Coverage limits, stated honestly

• hkex_licensing_deals / hkex_ipo_filings: require the Asian party to be HKEX-listed (Main Board or GEM). A private-to-private deal, or one between two A-share-only companies, is invisible here — use cninfo_disclosure_search for the A-share side.
• cninfo_disclosure_search: requires an A-share-listed party (Shenzhen or Shanghai, including STAR Market). A company listed only overseas (HK, US, or privately held) does not appear.
• A deal or listing with neither an HKEX-listed nor an A-share-listed nor an SEC-filing party (china-pharma / pharma-deals) is not visible to any tool in this catalog.
• Both HKEX tools only reach HKEXnews' current rolling title-search window (recently, roughly the last several weeks to a couple of months, depending on how common the phrase is) — see the trap above. cninfo_disclosure_search has no such limit; its since/until genuinely reach back in time.

Auth

None. Keyless on all three tools.

Data sources

• hkex_licensing_deals / hkex_ipo_filings: https://www1.hkexnews.hk/search/titleSearchServlet.do (HKEXnews public title search) and the linked filing PDFs under https://www1.hkexnews.hk/.
• cninfo_disclosure_search: https://www.cninfo.com.cn/new/hisAnnouncement/query (CNINFO's public disclosure search) and PDFs under https://static.cninfo.com.cn/.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "china-disclosures": {
      "url": "https://gateway.pipeworx.io/china-disclosures/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/china-disclosures/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1683+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/hkex_licensing_deals \
  -H 'Content-Type: application/json' \
  -d '{}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/hkex_licensing_deals. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "china-disclosures": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-china-disclosures"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-china-disclosures

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about China Disclosures data" })

The gateway picks the right tool and fills the arguments automatically.
