Patents Mcp

patents-mcp

[](https://golang.org) [](LICENSE) [](https://glama.ai/mcp/servers/tushariitr-19/patents-mcp)

An MCP (Model Context Protocol) server for patent search and prior art discovery, powered by the Google Patents public dataset on BigQuery.

Built with the official Go MCP SDK.

Why patents-mcp?

Existing patent MCP servers are either paid, single-source, or unmaintained. patents-mcp is:

• Free — built on Google Patents public dataset (1TB/month free on BigQuery)
• Open source — MIT licensed
• Production grade — structured logging, graceful shutdown, clean architecture
• Extensible — each tool is self-contained, easy to add new tools

Available Tools

| Tool | Description | |------|-------------| | search_patents | Search patents by keyword, technology area, or inventor name | | get_patent | Fetch full patent details by publication number | | get_patent_claims | Fetch patent claims text |

Prerequisites

• Go 1.21+
• A Google Cloud account (free)
• BigQuery API enabled on your GCP project

Setup

1. Google Cloud Setup

1. Create a GCP project at console.cloud.google.com
2. Enable the BigQuery API
3. Create a service account with the following roles:

• BigQuery Job User
• BigQuery Data Viewer

1. Download the service account JSON key

2. Install

git clone https://github.com/tushariitr-19/patents-mcp
cd patents-mcp
go build -o patents-mcp-server ./cmd/server/

3. Configure

export GOOGLE_APPLICATION_CREDENTIALS="/path/to/service-account.json"
export GCP_PROJECT_ID="your-gcp-project-id"

# Optional: enable debug logging
export DEBUG=true

Usage with Claude Desktop

Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "patents-mcp": {
      "command": "/path/to/patents-mcp-server",
      "env": {
        "GOOGLE_APPLICATION_CREDENTIALS": "/path/to/service-account.json",
        "GCP_PROJECT_ID": "your-gcp-project-id"
      }
    }
  }
}

Each tool owns its own dependencies — the server is agnostic of what tools do internally. Adding a new tool is a single line in server/server.go.

Contributing

PRs welcome. To add a new tool:

1. Create tools/.go
2. Define your input struct and tool definition
3. Register it in server/server.go with one line
