Installation

Installing via Smithery

To install trademark-mcp-server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @jordanburke/trademark-mcp-server --client claude

Manual Installation

pnpm install
pnpm build

⚠️ API Key Required

Important: The USPTO TSDR API requires an API key since October 2020. You must:

1. Register at USPTO Developer Portal
2. Get your API key from your account dashboard
3. Set environment variable: USPTO_API_KEY=your_api_key_here

Without an API key, all requests will return 401 Unauthorized errors.

Usage

Using npx (Recommended)

You can run the server directly using npx without installing:

# Set your API key first
export USPTO_API_KEY=your_api_key_here

# Then run the server
npx trademark-mcp-server

This will start the MCP server in stdio mode, ready to receive MCP protocol messages.

As an MCP Server (stdio)

If you have the package installed locally:

pnpm start
# or directly
node dist/bin.js

Using the Shell Script

A convenience shell script is provided:

./start-mcp-server.sh

As an HTTP Server

# Set your API key first
export USPTO_API_KEY=your_api_key_here

# Start HTTP server (default port 3000)
pnpm serve
# or directly
node dist/server.js

# Or specify a custom port
PORT=8080 pnpm serve

The HTTP server provides:

• Health check: http://localhost:3000/health
• Server info: http://localhost:3000/
• MCP endpoint: http://localhost:3001/mcp (FastMCP on port+1)

🐳 Docker Support

Quick Start with Docker

Run the trademark server as a Docker container:

# Pull and run from GitHub Container Registry
docker run -d \
  --name trademark-mcp-server \
  -p 3000:3000 \
  -e USPTO_API_KEY=your_api_key_here \
  ghcr.io/jordanburke/trademark-mcp-server:latest

Docker Compose

Create a docker-compose.yml file:

version: '3.8'
services:
  trademark-mcp-server:
    image: ghcr.io/jordanburke/trademark-mcp-server:latest
    ports:
      - "3000:3000"
    environment:
      - USPTO_API_KEY=your_api_key_here
    restart: unless-stopped
    healthcheck:
      test: ["CMD", "wget", "--no-verbose", "--tries=1", "--spider", "http://localhost:3000/health"]
      interval: 30s
      timeout: 10s
      retries: 3

Then run:

docker-compose up -d

Building Docker Image Locally

# Build the image
docker build -t trademark-mcp-server .

# Run the container
docker run -d \
