Blues Expert

Blues Expert is a Model Context Protocol (MCP) server that helps you build products with Notecard and Notehub.

When used with an LLM, Blues Expert provides best practices for firmware development, helps developers take advantage of Notecard capabilities, and supplies accurate information about Blues products to reduce hallucinations and errors.

Build

Requirements:

• Go (at least v1.27)
• Make
• Docker

make build

Install

Add the following to your mcp.json file (e.g. for Claude Desktop, this is claude_desktop_config.json):

{
  "mcpServers": {
    "blues-expert": {
      "type": "http",
      "url": "http://localhost:8080/expert/mcp"
    }
  }
}

Development

To run the MCP inspector, you'll need Node.js installed (at least v18).

make inspect-blues-expert

If you expose a local server through a tunnel (e.g. ngrok), set MCP_DISABLE_LOCALHOST_PROTECTION=1; otherwise the MCP SDK rejects tunneled requests with a 403.
