Patent MCP Server

🚀 中国专利最准确的开源 MCP。 Give your AI agent the ability to read CN patents with real accuracy — plus global coverage.

An MCP (Model Context Protocol) server that gives AI agents access to patent data — CN patents with CPC-aware correction, plus US/WO global coverage. Runs locally on your machine. No external API, no subscription. Always MIT.

Why Self-Deployed

• It's just Python. Install it, your agent uses it. No server to maintain, no credential to share.
• No API key for 80% of use cases. Patent details and claims come straight from Google Patents public pages.
• Your data stays local. Nothing leaves your machine except the same HTTP requests a browser would make.
• BigQuery search is optional. Only turn it on if you need full-text search across 1.4B records.

30-Second Install

pip install deeparchi-patent-mcp

Or from source:

git clone https://github.com/deeparchi-ai/patent-mcp-server.git
cd patent-mcp-server
pip install -e .

Quick Start

After pip install, the deeparchi-patent-mcp console script is on your PATH. Add this to your agent platform's MCP config:

Claude Desktop

{
  "mcpServers": {
    "patent-mcp": {
      "command": "deeparchi-patent-mcp",
      "args": []
    }
  }
}

Cursor / Windsurf / Cline

Same config as Claude Desktop above.

Hermes Agent

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

BigQuery is optional. Without GCP_PROJECT_ID the server starts normally and the web-backed tools work with no credentials. BigQuery-backed tools return a message explaining how to enable them. To turn them on, add an env var:

{
  "mcpServers": {
    "patent-mcp": {
      "command": "deeparchi-patent-mcp",
      "args": [],
      "env": { "GCP_PROJECT_ID": "your-gcp-project" }
    }
  }
}

Running from a source checkout

{
  "mcpServers": {
    "patent-mcp": {
      "command": "python",
      "args": ["-m", "server"],
      "cwd": "/path/to/patent-mcp-server/src"
    }
  }
}

Now ask your agent:

"Get patent US-7650331-B1 and summarize the claims."

What's Included

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

CN Patent Search (v1.7.0)

Three-layer discovery for Chinese patents:

• Keyword search works: query="芯片" + country=CN searches both English AND Chinese abstracts (v1.5.2 fix).
• Assignee filter: assignee="BOE" + country=CN → company/city-level patent landscape.
• CPC classification: Use parent CPC classes (H01L) for broader CN coverage; specific CPC codes (H01L25/065) tri
