This server offers real-time price data, market analysis, and historical trends through an easy-to-use interface. Supports both STDIO and Streamable HTTP transports.\n\n## Requirements\n\n- **Node.js 22.14+**\n- **CoinCap API key** via `COINCAP_API_KEY`\n\n## What's New\n\n- **BREAKING**: CoinCap v2 API removed. Now uses v3 API exclusively. A `COINCAP_API_KEY` is required (free tier available at [pro.coincap.io/dashboard](https://pro.coincap.io/dashboard))\n- Streamable HTTP transport added (while keeping STDIO compatibility)\n- Smithery CLI scripts to build and run the HTTP server\n- **6 new tools**: `assets-search`, `market-global`, `assets-compare`, `analysis-candlestick`, `price-convert`, `assets-info`\n- **Hierarchical tool naming**: All tools organized into category-prefixed names (`price-*`, `market-*`, `assets-*`, `analysis-*`)\n- **Output schemas**: All tools now declare `outputSchema` with `structuredContent` for type-safe responses\n- **MCP best practices**: `isError` flag on validation errors, server description, and `asset://{symbol}` resource template\n\n## Usage\n\nAdd this configuration to your Claude Desktop config file:\n\n- **MacOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`\n- **Windows**: `%APPDATA%/Claude/claude_desktop_config.json`\n\n```json\n{\n \"mcpServers\": {\n \"mcp-crypto-price\": {\n \"command\": \"npx\",\n \"args\": [\"-y\", \"mcp-crypto-price\"],\n \"env\": {\n \"COINCAP_API_KEY\": \"YOUR_API_KEY_HERE\"\n }\n }\n }\n}\n```\n\nIf your MCP client requires launching via `cmd.exe` on Windows:\n\n```json\n{\n \"mcpServers\": {\n \"mcp-crypto-price\": {\n \"command\": \"cmd\",\n \"args\": [\"/c\", \"npx\", \"-y\", \"mcp-crypto-price\"],\n \"env\": {\n \"COINCAP_API_KEY\": \"YOUR_API_KEY_HERE\"\n }\n }\n }\n}\n```\n\n### Development scripts\n\n```bash\npnpm dev # Development (HTTP server with hot reload via Smithery CLI)\npnpm build # Compile TypeScript → dist/\npnpm format # Format source files with Prettier\npnpm lint # Check for lint errors (ESLint + typescript-eslint)\npnpm lint:fix # Auto-fix lint errors\npnpm types:check # TypeScript type-check without emitting files\npnpm test # Run all tests with Vitest\npnpm test:coverage # Run tests with coverage report (Vitest)\npnpm inspector # Open MCP inspector for interactive debugging\n```\n\n### Run as Streamable HTTP server\n\nYou can run the server over HTTP for environments that support MCP over HTTP streaming.\n\n- Dev server (recommended during development):\n\n```bash\npnpm dev\n```\n\n- Build and run the HTTP server:\n\n```bash\n# Build (outputs to dist/)\npnpm build\n\n# Start the HTTP server\npnpm start:http\n```\n\n- Build and run the STDIO server:\n\n```bash\n# Build (outputs to dist/)\npnpm build\n\n# Start the STDIO server\npnpm start:stdio\n```\n\nThe server listens on port 3000 by default (override with `PORT`). For clients that connect over HTTP (e.g. Smithery, Claude.ai), pass your API key as a query parameter:\n\n```\nhttp://localhost:3000/mcp?COINCAP_API_KEY=YOUR_API_KEY_HERE\n```\n\nFor remote deployments:\n\n```\nhttps://mcp-crypto-price.codemonkeyinnovations.com/mcp?COINCAP_API_KEY=YOUR_API_KEY_HERE\n```\n\n## Required: CoinCap API Key\n\nThis server uses the CoinCap v3 API, which requires an API key. A **free tier** is available.\n\n1. Sign up and get your API key at [pro.coincap.io/dashboard](https://pro.coincap.io/dashboard)\n2. Add the key to your MCP client configuration:\n - **STDIO**: via the `COINCAP_API_KEY` environment variable (see Usage examples above)\n - **HTTP**: via the `COINCAP_API_KEY` query parameter in the connection URL (e.g. `/mcp?COINCAP_API_KEY=your_key`)\n\nWithout a valid API key, all tools will return an error with instructions on how to obtain one.\n\n## Note for Smithery CLI users\n\nThis MCP server works directly via `pnpm dlx` (configs above) and does not require Smithery.\n\nIf you do use the Smithery CLI, authenticate with `smithery auth login` or by setting `SMITHERY_API_KEY` in your environment. Recent versions of the Smithery CLI do not support passing API keys via `--key` (or older `--profile` patterns).\n\nLaunch Claude Desktop to start using the crypto analysis tools.\n\n## Tools\n\n####
