You can also pass the key as a flag instead of an env var:npx -y quackr-mcp --api-key YOUR_API_KEY_HERE.
Remote (recommended)— connect directly to the hosted endpoint. Add to your~/.claude.json(or a project.mcp.json):
{ "mcpServers": { "quackr": { "type": "http", "url": "https://mcp.quackr.io/", "headers": { "Authorization": "Bearer YOUR_API_KEY_HERE" } } } }
claude mcp add --transport http quackr https://mcp.quackr.io/ --header "Authorization: Bearer YOUR_API_KEY_HERE"
Claude Desktop's JSON config only supports local (stdio) servers. Use the npm launcher (seeInstall via npm) by adding thenpx quackr-mcpconfig above toclaude_desktop_config.json, then restart Claude Desktop.
Alternatively, add Quackr as a remote connector:Settings → Connectors → Add custom connector, enterhttps://mcp.quackr.io/, and add anAuthorizationheader with the valueBearer YOUR_API_KEY.
Any client supporting remote Streamable HTTP MCP servers with custom headers works. Point it athttps://mcp.quackr.io/and pass your key via theAuthorization: Bearer YOUR_API_KEYheader.
Quackr also exposes a full REST API athttps://api.quackr.io/— seeapi.quackr.io/swagger.jsonfor the full spec. Samex-api-keyauth.
