Install as a plugin

This repository is also a plugin for Cursor, Grok Bot and Grok Build. It contains the connection to the server above and four skills that tell the agent when to use it. There are no rules, commands, hooks or scripts, so there is no code to run on your machine.

• Cursor and Grok Bot: open the plugin marketplace, search for Greenlit Books, and install.
• Grok Build: run /marketplace, search for Greenlit Books, and install.

Network and credentials

• The plugin connects to one endpoint, https://greenlitbooks.com/api/mcp, over HTTPS (streamable HTTP).
• No credentials. There is no sign-in, no OAuth and no API key, and the plugin reads nothing from your disk.
• Every tool is read-only. Requests are handled as described in the privacy policy.

Notes

• Read-only. No accounts, no keys, no rate-limit registration.
• The server is stateless; every response is derived from the live catalog.
• Amazon links are clean /dp/ product URLs.
• The catalog intentionally omits publication dates, page counts, and ISBNs: it carries no verified source for them, and nothing is invented.
• Glossary definitions are quoted, not written: each is verified verbatim against the book's manuscript when the site is built. Terms borrowed from another field (blast radius, span of control) say so.
• Every define_term and get_concept result ends with a links block. Cite the glossary or concept URL; send readers to freeChapter first, then amazonKindle.

This repository holds the server manifest, the plugin manifests and the documentation. The server itself runs on greenlitbooks.com.
