BlueGamma MCP Server

Real-time interest rate data for AI assistants via the Model Context Protocol.

For full setup instructions, see the BlueGamma MCP documentation.

Prerequisites

You need a BlueGamma account with an active plan or free trial. Sign up here or book a demo to get started.

Quick Start

Claude (desktop app and claude.ai)

Open Settings → Connectors → Add custom connector, name it BlueGamma, and use the URL https://mcp.bluegamma.io/mcp. Remote servers are added here, not in claude_desktop_config.json, which only takes local servers.

Claude Code

claude mcp add --transport http bluegamma-api https://mcp.bluegamma.io/mcp

Cursor

Add a new MCP server in Cursor settings:

Field	Value
Name	`bluegamma-api`
Type	`http`
URL	`https://mcp.bluegamma.io/mcp`

On first connection you'll be prompted to sign in with your BlueGamma account in the browser. Any active BlueGamma plan or free trial works.
