# /mcp

Beta

Add the JustTCG MCP server to your favorite coding agents with a single command. Supports Claude Code, Cursor, OpenCode, VSCode, and more.

`GET https://mcp.justtcg.com`

## Install

Use the `add-mcp` CLI to automate configuration across LLMs and IDEs at both project and global scope.

```bash
npx add-mcp https://mcp.justtcg.com --header "x-api-key: YOUR_API_KEY"
```

Some agents natively detect the connection string format, while others may require the transport layer to be explicitly set.

## Example prompt usages

-   "Analyze the price trajectory of the latest Pokemon set."
-   "What is the best performing TCG set released in the last 6 months?"
-   "Give me a 5 item list of Magic cards that I should consider collecting based on strong performance."

## Troubleshooting

-   Verify the JustTCG server URL is correctly specified (`https://mcp.justtcg.com`).
-   Check your agent's explicit MCP configuration JSON for unescaped characters.
-   In VS Code or Cursor, confirm that the transport layer supports raw HTTP stream handling natively.
