Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

notes
list_notes
List every readable note: project notes (/library/notes/), reference notes (/library/reference/), library pages and the mission page. Gives slug, iil_id (permanent ID), aliases (old slugs), kind, title, date, status, url, page, license, checked_on (reference notes add category, source_url).
search_notes
Case-insensitive search across all notes, reference notes, library pages and the mission page. Every query word must match (title, tags, or body), with light stemming; an exact phrase ranks first. Returns matching slugs with line snippets. SI / RSI also match self-improvement and superintelligence. Queries are kept only in a private usage log (see llms.txt).
ask
ask
Answer a question about iinventedlight from the public notes and library in one call. Returns {answer (1-3 lines), confidence 0-1, sources, fields, next}. Follow next when confidence is low. Only a short normalized topic of unanswered questions is kept, never the question itself.
atlas
atlas
Compact map of topics -> fact ids (doc#n) and docs. Use to plan which ask/read_note calls to make. Same content as resource https://iinventedlight.com/library/atlas.json
feedback
read_feedback
Read approved feedback for one public note: rating average, like and dislike counts, and attached comments, corrections and insights. Pending feedback is not shown. Does not change the note.
note
read_note
Read one public note by slug (from list_notes), old slug, or permanent ID (iil:note:...). Returns the note's markdown, then its permanent ID and a Cite this block (plain text and BibTeX). Optional sections: heading or bold-label names to return only those parts; pass [] to list the available sections.
submit
submit_contribution
Submit feedback or a library note. A type=note submission requires a valid access key (HTTP header 'Authorization: Bearer <key>'); without one it is rejected. Feedback (rating, like, dislike, comment, correction, insight) needs no key. ALWAYS ask your human user first: tell them exactly what you will submit and why, and only call this if they agree. Never include personal information, private chat content, secrets, or another person's data. Feedback is held as pending and is not shown by read_feedback or anywhere public until a person approves it. Feedback never changes a note's published text or creates a note. A type=note submission is human-reviewed and never auto-published.

iinventedlight Library — questions

Answers built from our own checks of this server.

What can iinventedlight Library do?
It exposes 7 tools, read directly from the server on our last check. Among them: ask, atlas, list_notes, read_feedback, read_note, search_notes and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is iinventedlight Library working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 274 ms. The bar chart above shows every period we have measured.
How do I connect iinventedlight Library?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does iinventedlight Library need an API key?
No. iinventedlight Library 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 iinventedlight Library?
It answers our handshake in 274 ms on average, which is faster than 61% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
