Changelog
v0.2.0 (2025-04-17)
- Fix: Implemented empty handlers for
resources/listandprompts/listMCP methods. - Fix: Declared
promptscapability in server initialization. - Chore: Updated dependencies.
These changes aim to improve compatibility with MCP clients like Claude Desktop which may require these standard endpoints, though direct testing with Claude Desktop has not yet been performed.
Features
- Provides an MCP tool
search_patentsto search Google Patents. - Uses SerpApi as the backend.
- Can be run directly using
npxwithout local installation.
Prerequisites

Questions
What tools does Google Patents expose?
1 in total: 1 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Google Patents safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Google Patents need?
It reads SERPAPI_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does Google Patents run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as @kunihiros/google-patents-mcp at 0.2.0.
How current is this page?
The grade is for one exact copy of the source (fe6d12ca06d1), read on 2026-10-08. The repository is watched and re-audited when it changes.
