## Purpose

`crypto-mcp` is a compact MCP server for crypto-related tools.
The current goal is a clean HTTP JSON-RPC 2.0 endpoint that works well with MCP clients such as mcporter.

## Current interface

- `GET /` → tool discovery JSON
- `GET /health` → health and cache stats
- `POST /mcp` → JSON-RPC 2.0 MCP transport

## Tool set

- `get_price`
- `get_ohlcv`
- `get_indicator`
- `get_market_snapshot`
- `get_top_movers`

## Notes

- No SSE transport.
- No event stream.
- No URL-fetching helper tool.
- Keep the transport small and predictable.

## Verification

- `./tests.sh`
- `./run.sh`
