What it does
Patsnap hosts an MCP server that searches patent offices worldwide and scientific literature in one request. `patsnap_search` takes a natural-language description, keywords with BM25 matching, or structured filters such as assignee, inventor, IPC class, jurisdiction, dates, legal status and citations. One call returns up to 100 results. `patsnap_fetch` retrieves up to 100 selected records by URL or publication number and returns them as Markdown: bibliography, abstract, claims, description, citations, legal events and patent family. Papers come with bibliographic data and abstracts. The data lives in the Patsnap cloud; the repository itself holds only a stdio bridge for Docker.
Who it is for. Patent attorneys, R&D analysts and founders who check novelty or study competitors from an agent chat.
Good fit when
- You need patents of a competitor filtered by assignee and IPC class.
- Before filing, you check whether the idea already appears in papers and patents.
- An agent assembles a prior-art overview with links to abstracts and claims.
- Citations and legal events are opened for selected patents.
- One topical query covers patents and papers from arXiv or PubMed.
Not a fit when
- You need a legal patentability opinion: search results do not replace an attorney.
- Queries cannot be sent to an external cloud service.
- You need offline access without a Patsnap key.
Example request

Environment variables
PATSNAP_API_KEYrequired, secret- Patsnap Open Platform key for the Docker bridge
Limitations
Access uses a Patsnap Open Platform key. New accounts get 10,000 free credits with no card; later usage follows platform terms. The Claude Code example places the key in the request URL, so it ends up in client configuration and shell history; the Docker variant takes it from the `PATSNAP_API_KEY` environment variable. Data completeness varies by authority and patent, and filter names follow the current hosted schema. The stdio bridge without a key only returns tool definitions. The latest commit in the repository dates from August 2026.
How to disable. Run `claude mcp remove search-tool` or delete the `patsnap_patent_literature` entry from the Cursor or Windsurf config. Revoke the key on the Patsnap Open Platform page.
FAQ
Which tools does the server have?
Two: `patsnap_search` finds patents or papers and `patsnap_fetch` returns full records as Markdown. Search returns up to 100 results per call and fetch handles the same volume.
Is a paid plan required?
Not to start. Registering on Patsnap Open Platform grants 10,000 free credits with no card. Terms after that are listed on the platform.
How do I connect it in Cursor or Windsurf?
Add an MCP entry with the server URL, your key and the `streamableHttp` type. A ready snippet sits in the README.
Can the server run locally?
Partly. The repository ships a stdio bridge for Docker that serves tool definitions without a key and forwards calls to the Patsnap cloud when `PATSNAP_API_KEY` is set.
Which paper sources are covered?
They include PubMed, arXiv, Nature, Science, SSRN and Zenodo. Patsnap maintains the full list on its Global Data Coverage page.
