deeparchi-patent-mcp 1.3.2

Global patent MCP server — search 1.4B patents via BigQuery + Google Patents. MIT. Agent-native.

Patent MCP Server

Patent infrastructure for AI agents — turn 1.4 billion global patents into structured fuel your agent can consume.

Why Patent MCP

PatSnap is a patent database for humans. Patent MCP is a patent API for AI agents.

	PatSnap	Patent MCP
🎯 User	Human in a browser	AI agent in a workflow
💰 Cost/year	$5,000 – $500,000	$0 (self-hosted), $79/mo (hosted)
🔌 Integration	Manual Excel export	MCP-native — Claude Code / Cursor / Hermes
📊 Output	Web pages + PDF reports	Structured Pydantic objects, zero-loss consumption
🏠 Deployment	SaaS only	Self-hosted or managed
🔓 License	Proprietary	MIT open source

Patent data is public (Google Patents / BigQuery CC-BY-4.0). The difference isn't the data — it's whether an agent can consume it directly.

Quick Start

pip install deeparchi-patent-mcp

Claude Desktop

{
  "mcpServers": {
    "patent-mcp": {
      "command": "python",
      "args": ["-m", "src.server"]
    }
  }
}

Hermes Agent / Cursor / Windsurf

mcp_servers:
  patent-mcp:
    command: "deeparchi-patent-mcp"

Then ask your agent:

"Search for Tesla's autonomous driving patents filed in China since 2023." "Get patent US-7650331-B1 and analyze the claims for novelty."

Three Tools

Tool	What It Does	Setup Required?
search_patents	Search 1.4B patents — keyword, country, CPC, date range	Optional GCP
get_patent	Full details — classifications, citations (X/Y/A/D), family, inventors	None
get_patent_claims	US patent claims text — legal scope of protection	None

The latter two cover 80% of use cases. Zero cost. Zero setup.

Note: CPC classification coverage is incomplete for Chinese (CN) patents. For CN searches, prefer keyword search.

---

Optional: Enable BigQuery Search

search_patents uses Google BigQuery (1 TB/month free tier covers individual use):

export GOOGLE_APPLICATION_CREDENTIALS="/path/to/key.json"
export GCP_PROJECT_ID="your-project-id"

• Web scraping — ~1.5s, free, no credentials
• BigQuery search — 1.4B records, CN full-text, optional
• Smart fallback — get_patent tries web first, auto-falls back to BigQuery
