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.
Existing patent MCP servers are either paid, single-source, or unmaintained. patents-mcp is:
| 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 |
BigQuery Job UserBigQuery Data Viewergit clone https://github.com/tushariitr-19/patents-mcp
cd patents-mcp
go build -o patents-mcp-server ./cmd/server/
export GOOGLE_APPLICATION_CREDENTIALS="/path/to/service-account.json"
export GCP_PROJECT_ID="your-gcp-project-id"
# Optional: enable debug logging
export DEBUG=true
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"
}
}
}
}

Once connected to Claude Desktop:
patents-mcp/
├── cmd/server/main.go ← entry point, env vars, graceful shutdown
├── server/server.go ← MCP server setup, tool registration

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.
