## 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 /` → health + tool list
- `GET /health` → health + cache stats
- FastMCP SSE transport mounted at `GET /mcp/sse`

Tool calls are performed via FastMCP’s message transport under `/mcp/messages/`.

## Tool set

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

## Notes

- Uses SSE transport (FastMCP) for MCP compatibility.
- No extra custom event endpoints beyond FastMCP.
- Keep the transport small and predictable.

## Verification

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