Built for the Agentic Web

We designed our MCP Server to respect your API limits while giving models exactly what they need to act dynamically on market changes.

Same API Key

Authenticate exactly as you do today using the x-api-key header. No need to manage secondary credentials for your agents.

Zero New Fees

MCP requests count towards your standard plan quota. Implement AI workflows seamlessly with no premium AI upcharges.

Context-Window Optimized

Tools automatically utilize include_price_history=false and strict batching to keep token usage slim and efficient for Context Windows.

Ready in 60 seconds

Install the JustTCG MCP server with a single command using the open-source add-mcp CLI. It automatically configures your favorite coding agents like Cursor, Claude Code, VSCode, and more.

  2. 2Run the command in your project directory (or use -g for global installation).
