See the [Configuration section](#configuration) below for setup instructions.152153### A) Docker (Recommended)154155BGG MCP is published to [Docker Hub](https://hub.docker.com/r/kdaniel/bgg-mcp) and listed on the [MCP Registry](https://github.com/modelcontextprotocol/registry). Add the following to your `claude_desktop_config.json` (Claude Desktop) or `settings.json` (VS Code / Cursor):156157```json158"bgg": {159 "command": "docker",160 "args": ["run", "-i", "--rm",161 "-e", "BGG_API_KEY",162 "-e", "BGG_USERNAME",163 "kdaniel/bgg-mcp"164 ],165 "env": {166 "BGG_API_KEY": "your_api_key_here",167 "BGG_USERNAME": "your_bgg_username"168 }169}170```171172> See [Configuration](#configuration) below for details on obtaining a BGG API key and setting up your username.173174For more details on connecting MCP servers to your client, see the [official MCP guide](https://modelcontextprotocol.io/docs/develop/connect-local-servers).175176### B) Manual Setup177178#### 1. Install Go179180You will need to have Go installed on your system to build binary. This can be easily [downloaded and setup here](https://go.dev/doc/install), or you can use the package manager that you prefer such as Brew.181182#### 2. Build183184The project includes a Makefile to simplify building and managing the binary.185186```bash187# Build the application (output goes to build/bgg-mcp)188make build189190# Clean build artifacts191make clean192193# Both clean and build194make all195```196197Or you can simply build it directly with Go...198199```bash200go build -o build/bgg-mcp201```202203#### 3. Add MCP Config204205In the `settings.json` (VS Code / Cursor) or `claude_desktop_config.json` add the following to your list of servers, pointing it to the binary you created earlier, once you load up your AI tool you should see the tools provided by the server connected:206207```json208"bgg": {209 "command": "path/to/build/bgg-mcp",210 "args": ["-mode", "stdio"]211}212```213214More details for configuring Claude can be [found here](https://modelcontextprotocol.io/quickstart/user).215216## Configuration217218### Authentication219220BGG MCP v2.0+ uses the GoGeek v2.0 library which requires authentication for reliable access to BoardGameGeek's API.221222You can configure authentication using **either** `BGG_API_KEY` (recommended) or `BGG_COOKIE`:223224#### Authentication Setup225226##### Option 1: API Key (Recommended)227228Get an API key from [BoardGameGeek's API application form](https://boardgamegeek.com/applications) and add it to your configuration:229230```json231"bgg": {232 "env": {233 "BGG_API_KEY": "your_api_key_here"234 }235}236```237238##### Option 2: Cookie Authentication239240Alternatively, you can use cookie-based authentication:241242```json243"bgg": {244 "env": {245 "BGG_COOKIE": "bggusername=user; bggpassword=pass; SessionID=xyz"246 }247}248```249250**Note**: If both are provided, `BGG_API_KEY` will be used by default.251252### Username Configuration253254You can optionally set the `BGG_USERNAME` environment variable to enable "me" and "my" references in queries without needing to explicitly state your username:255256```json257"bgg": {258 "env": {259 "BGG_USERNAME": "your_bgg_username",260 "BGG_API_KEY": "your_api_key_here"261 }262}263```264265This enables:266267- **Collection queries**: "Show my collection" instead of specifying your username268- **User queries**: "Show my BGG profile"269- **AI assistance**: The AI can automatically use your username for comparisons and analysis270271**Note**: When you use self-references (me, my, I) without setting BGG_USERNAME, you'll get a clear error message.272
