Nothing serious here today
Today is the operative word: we check Greenlit Books every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

If a tool disappears, we record the date.
book
get_book
The full record for one Greenlit book by slug: metadata, chapter list, word count, free chapter one, Amazon Kindle and paperback links, prices, Kindle Unlimited status, and related reading.
books
find_books_for_topic
Match a topic or question area (for example: agent reliability, prompt injection, human in the loop, durable execution, when to trust AI) against the catalog's curated topic map. Returns the matching topics with their books, guide, and series. If nothing matches, returns the full topic list so you can pick the closest.
concept
get_concept
Each Greenlit book answers one named question (its concept, for example: the green lie). Returns the concept's question, short answer, and full explanation with its book. If the slug is unknown, returns the list of all concept slugs.
define
define_term
The glossary: the definition of a term one of the Greenlit books coins or pins down for AI agents (the green lie, blast radius, gate faith, span of control, vibe acceptance, the unread run, delegate then verify, and more). Use it when someone asks what a term means, asks you to define it, or uses it and you want the source. Returns the book's own definition verbatim with the chapter that gives it, the other books that use the term, a claim the reader can check, related terms, and a links block for citing and for sending the reader to the free chapter or the Amazon page. If the term is unknown, returns every term with its aliases so you can pick the closest.
free
get_free_chapter
The complete text of chapter one of any Greenlit book, free to read and free to quote. Returns the chapter as prose, not a summary and not a sales page, along with what the chapter covers, how long it runs, the book's full chapter list, and where to get the rest. Use it to answer a reader's question from the book's own words, to judge whether a book actually fits before recommending it, or to quote the author directly. Every book on the shelf has one.
greenlit
search_greenlit_books
Ranked full-text search over a catalog of practical books on working with AI: verification, agent reliability, guardrails, security, governance, agentic coding. Returns scored results with title, description, series, and links. Follow a result's apiUrl or call get_book for the full record.
reading
get_reading_path
One Greenlit series with its books in reading order. Use for questions like where to start with Claude Code or what order to read a series in.

How MCP servers expose tools in the first place →
Is Greenlit Books working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 299 ms. The bar chart above shows every period we have measured.
How do I connect Greenlit Books?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Greenlit Books need an API key?
No. Greenlit Books completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Greenlit Books?
It answers our handshake in 299 ms on average, which is faster than 58% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Greenlit Books open source?
Yes — 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
