jokebox

jokebox serves dad jokes from icanhazdadjoke.com. Ask for a joke at random, hunt for jokes that mention a word or phrase, or pull up one specific joke again when you know its ID. One binary offers both a small command-line interface and a stdio MCP server, so the same install works in a terminal and inside an MCP client.

There is nothing to configure: the upstream service is public, needs no API key, and asks only that clients identify themselves and accept JSON answers — jokebox does both on every request.

Install

npx @reneturcios/jokebox random

Or run the container image:

docker run -i ghcr.io/cloudcorprecords/jokebox

The container defaults to the MCP server (see below). Pass CLI arguments to use it as a CLI instead.

CLI

jokebox random
jokebox search pizza
jokebox search pizza --limit 3
jokebox joke R7UfaahVfFd

jokebox --version

Every command prints JSON. random prints one joke as { "id": ..., "joke": ... }. search prints { "term": ..., "total_jokes": ..., "jokes": [...] }, where total_jokes counts every match the upstream holds for the term and jokes holds the requested page of them. joke prints the single joke stored under the given ID.

Search limits: --limit is an integer from 1 to 30 and defaults to 5. An out-of-range limit, a missing search term, or a missing joke ID is a usage error and no request is sent.

Exit codes: 0 on success, 1 when the upstream request fails (the error names the HTTP status or the malformed answer), 2 for usage errors.

MCP server

One bin serves both faces. The mcp subcommand starts a stdio MCP server:

npx -y @reneturcios/jokebox mcp

MCP client configuration:

{
  "mcpServers": {
    "jokebox": {
      "command": "npx",
      "args": ["-y", "@reneturcios/jokebox", "mcp"]
    }
  }
}
