Documentation

The Waveleta MCP server exposes the Waveleta Developer API as tools that MCP clients such as Cursor and Claude can call. It is read-only market data: it has no trading tools and cannot place, change or cancel orders.

Endpoint

https://api.waveleta.com/mcp (MCP Streamable HTTP). Authenticate with your existing Developer API key as Authorization: Bearer wl_….

Pricing

Each tool call is one Developer API call and is billed exactly like the REST API: €0.002 per successful call from your prepaid balance, with €2 free starter credit. Connecting and listing tools is free. Failed calls are not charged.

`get_radar_signals`	Waveleta Radar ranked signal candidates	`/v1/radar/candidates`
`get_equity_history`	US equities history (early access)	`/v1/equities/history`
`get_fx_rates`	FX daily reference rates	`/v1/fx/rates`

Cursor

Add this to ~/.cursor/mcp.json (or .cursor/mcp.json in a project):

{
  "mcpServers": {
    "waveleta": {
      "url": "https://api.waveleta.com/mcp",
      "headers": { "Authorization": "Bearer wl_YOUR_KEY" }
    }
  }
}

Claude Code

claude mcp add --transport http waveleta https://api.waveleta.com/mcp \
  --header "Authorization: Bearer wl_YOUR_KEY"

Claude Desktop

Use the mcp-remote bridge (requires Node.js) in claude_desktop_config.json:

{
  "mcpServers": {
    "waveleta": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://api.waveleta.com/mcp",
               "--header", "Authorization:${WAVELETA_AUTH}"],
      "env": { "WAVELETA_AUTH": "Bearer wl_YOUR_KEY" }
    }
  }
}

ChatGPT

Limited for now. ChatGPT custom connectors expect OAuth sign-in rather than an API key header, which this server does not offer yet. Support is coming; until then, use Cursor or Claude.

Test with curl

curl -s https://api.waveleta.com/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer wl_YOUR_KEY" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

To make retries safe, send an Idempotency-Key header with a unique value per call; a repeated key is not charged twice.

Keep your key safe

Your key sits in your client's config file. Don't commit it to a repository. If it is exposed, revoke it on your developer dashboard and create a new one. Waveleta data is informational only and is not investment advice.
