Claude Code

# transport must be http (Streamable HTTP)
claude mcp add --transport http exrate https://mcp.banks-rates.com

Cursor

// Cursor → Settings → MCP → Add Server
// Transport: HTTP   URL: https://mcp.banks-rates.com/

The transport is Streamable HTTP; the server URL is the same across every MCP-compatible client: https://mcp.banks-rates.com/.

Authentication & limits

The server works without authentication at the free per-IP limits (12 requests/hour, 256/day). For higher limits (16/min, 800/hour, 16k/day), issue an API key in the console and add it as a bearer header:

# optional: a console API key for higher limits
claude mcp add --transport http exrate https://mcp.banks-rates.com \
  --header "Authorization: Bearer brk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

No OAuth is required. When a limit is hit the tool result reports a rate_limited error.
