# Patsnap Patent & Literature Search (OAuth) — AI Connector Patsnap Patent & Literature Search (OAuth) publishes 2 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/productivity/patsnap-patent-literature-search-oauth/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Productivity](https://node8.ai/ai-connectors/productivity/) # Patsnap Patent & Literature Search (OAuth) Patent and scientific literature search across Patsnap databases Listed in Claude · 2 published tools · Community-listed [Claude connector docs](https://open.patsnap.com/devportal/guides/mcp-quickstart) [patsnap.com](https://www.patsnap.com/) Overview ## What Patsnap Patent & Literature Search (OAuth) does Patsnap runs patent and scientific literature databases, and this connector searches both at once. Queries can be natural language, semantic or keyword, with pre-filters applied before retrieval so results narrow without a second pass. Alongside search, bibliographic detail for a patent or a paper comes back as Markdown, a deliberate formatting choice for text-based clients. Two tools are recorded, a narrow surface relative to the size of the databases behind it. The tier is community and connection uses OAuth. A Patsnap account with the relevant database entitlements is the prerequisite. ### Who it is for Patent analysts and R&D researchers running prior art and literature searches. ### Tool surface Two tools, one unified search and one bibliographic fetch, is a spare shape for databases this size, and with OAuth in front of tools/list even that pairing is inferred from the description. Availability ## Where Patsnap Patent & Literature Search (OAuth) is listed Patsnap Patent & Literature Search (OAuth) is listed in the Claude connectors directory only. Patsnap has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Patsnap Patent & Literature Search (OAuth) publishes 2 tools to Claude, a deliberately narrow surface; only 5.3% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Productivity publishes 12, so this one sits 10 tools below its bucket's median, 408th of 462. It falls in the 1-3 tools band, which holds 16.4% of the Claude directory. Patsnap Patent & Literature Search (OAuth) publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

It is the default for a self-published server, and says nothing either way about quality. In the publisher's words ## How Patsnap describes it > A professional tool enabling deep, integrated search across the Patsnap global patent and literature databases simultaneously. It supports natural language queries, semantic search, and keyword search, backed by precise pre-filtering capabilities for efficient and accurate retrieval of scientific and patent intelligence. This MCP also allows users to fetch basic bibliographic data for patents or literature in Markdown format. Quoted from the connector's own Claude directory listing as captured in August 2026.
