A simple MCP server with packaged tools
A simple MCP server with packaged tools. The octocat harry potter mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 1 defined tool rather than through you.
In the .env file, you'll see environment variable placeholders, one for each workspace that the selected tools are from. For example, if you selected requests from 2 workspaces, e.g. Acme and Widgets, you'll see two placeholders:
Everything the assistant can do here goes through one of these:
house — The name of the Hogwarts house to retrieve characters fromYou will need 2 environment variables: ACME_API_KEY, WIDGETS_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
The server ships on npm as COPY, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Octocat Harry Potter's toolset — house — is a fair guide to whether it matches your workflow. It is maintained by jonico; worth a glance at recent repository activity before you build anything load-bearing on it.
