Getting started

You need Node.js 20 or later.

In an agent built on agent-kit

Install its extension from Falken's Lab's marketplace, which runs this server at a fixed version and adds the skills to use it well:

my-agent extension marketplace add falkenslab/agent-extensions
my-agent extension add asker-mcp@falkenslab

claude mcp add asker-mcp -- npx -y @falkenslab/asker-mcp

Or, with its skills, as a plugin from the same marketplace:

claude plugin marketplace add falkenslab/agent-extensions
claude plugin install asker-mcp@falkenslab

Ask the agent: "Which version of asker-mcp are you using?" It calls server_info.
