everglow-mcp-bridge

STDIO to Streamable HTTP bridge for the Everglow Connect MCP server.

It lets stdio-only MCP clients (such as Claude Desktop) talk to the Everglow MCP server, which exposes a Streamable HTTP endpoint.

Usage

Set the environment variables and run the bridge:

export MCP_ENDPOINT="http://localhost:4000/mcp-server"
export MCP_BEARER_TOKEN="<your-token>"
npx -y everglow-mcp-bridge

        "MCP_BEARER_TOKEN": "<your-token>"
      }
    }
  }
}
