Point Cursor or Claude at a read-only market-data MCP (Waveleta)

Waveleta has launched a remote MCP (Message Control Protocol) server accessible at https://api.waveleta.com/mcp. This server provides access to market data, including crypto tickers, ranked market signals, foreign exchange rates, commodity histories, and US equities data. However, it is important to note that the MCP server cannot execute trades.

Developers can authenticate using a Bearer token, which is their existing Waveleta Developer API key. There is a €2 free starter credit when creating a new key, with subsequent calls costing €0.002 each (flat rate, not per-row). Additional funds can be added starting at €20.

The MCP server presents several advantages over raw HTTP methods. If developers already utilize Cursor, Claude Desktop, or similar MCP clients, pointing these clients at the remote URL is often quicker than integrating a new SDK. The same prepaid key functions for both the MCP server and the REST Developer API.

Some practical applications for the server include fetching today's top crypto signals, displaying the bid and ask prices for BTC/EUR, and obtaining the EUR/USD reference rate. Trading, however, is a separate product offered through the €39 plan (with an additional €19 add-on) that utilizes trade-only exchange API keys and does not involve fund management.

It is worth mentioning that Waveleta is based in Paris and serves clients worldwide. For further information, developers can refer to the MCP documentation at https://waveleta.com/developer/mcp, the Developer API at https://waveleta.com/developer/api, or the trade-only key guide at https://waveleta.com/guides/api-key-without-withdrawal.
