# realcryptocap-mcp

**RealCryptoCap: market cap without the stablecoins.**

MCP tools for real crypto market cap, native Top 500, coin lookup, and market briefs.

## Access and pricing (required)

**API / CLI / MCP are Pro and Ultra only (paid).** This is not a free MCP.

| Plan | Price |
|---|---|
| Pro | $25/mo or $250/yr |
| Ultra | $59/mo or $588/yr |

You need a RealCryptoCap API key (`rci_...`) from [realcryptocap.com/account](https://realcryptocap.com/account).

Unauthenticated calls fail. Pro/Ultra subscription required.

Separate limited free surface: WebMCP on the site pages **except Market Data** (index / search / open page / ask AI). That is not these MCP data tools.

## Glama quality checks

`Dockerfile` starts the stdio MCP server. It answers MCP introspection (`initialize`, `tools/list`) without a key; data tools require a paid Pro/Ultra `RCI_API_KEY`.
