About Alexandria

Alexandria is an MCP server published by the GitHub account The-40-Thieves. Search, read, and cite across 152 libraries: 11 tools, 3 prompts, and a full-text resource.

It runs on your own machine: your AI client starts it from the npm package @the-40-thieves/alexandria-mcp at version 11.0.0.

It asks for 10 secrets: OPENAI_API_KEY, ALEXANDRIA_API_KEY, CORE_API_KEY, COURTLISTENER_API_KEY, GOVINFO_API_KEY, GOOGLE_BOOKS_API_KEY, GITHUB_TOKEN, NASA_ADS_API_KEY, EUROPEANA_API_KEY and SEMANTIC_SCHOLAR_API_KEY. Give it a key with the least access that still works.

Version 11.0.0 was published on 5 September 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 1 warn, 0 fail, 1 info. How we check.

What it asks for

Variable	Required	Secret	Description
`OPENAI_API_KEY`	No	Yes	OpenAI key for routing (library_ask), synthesis (library_answer, library_research), and embeddings (library_ingest). Search and read tools work without it.
`ALEXANDRIA_BASE_URL`	No	No	OpenAI-compatible gateway base URL shared by every LLM role (router, synth, research, embeddings, rerank). Falls back to https://api.openai.com/v1.
`ALEXANDRIA_API_KEY`	No	Yes	API key paired with ALEXANDRIA_BASE_URL. Falls back to OPENAI_API_KEY.
`CORE_API_KEY`	No	Yes	Unlocks the core source (CORE, 57M+ open access papers). Free key from core.ac.uk/services/api.
`COURTLISTENER_API_KEY`	No	Yes	Unlocks the courtlistener source (US federal and state court opinions). Free key from courtlistener.com.
`GOVINFO_API_KEY`	No	Yes	Unlocks govinfo (Congressional Record, Federal Register, US Code); also accepted by congress and regulations. Free key from api.data.gov.
`GOOGLE_BOOKS_API_KEY`	No	Yes	Unlocks the googlebooks source (40M+ books). Free key from the Google Cloud Console (Books API).
`GITHUB_TOKEN`	No	Yes	Unlocks githubsearch and githubmcp (GitHub code search); optional for ghsa and openiti. Public-repo read scope is enough.
`NASA_ADS_API_KEY`	No	Yes	Unlocks the nasaads source (NASA Astrophysics Data System). Free key from ui.adsabs.harvard.edu.
`EUROPEANA_API_KEY`	No	Yes	Unlocks the europeana source (50M+ European cultural heritage items). Free key from apis.europeana.eu.
`SEMANTIC_SCHOLAR_API_KEY`	No	Yes	Optional for semanticscholar and library_recommend; raises the rate limit. Free key from semanticscholar.org/product/api.

What these checks don't cover

We did not run this server, so we don't know what it does when it runs. We read its package code on 2026-10-29 without running it, and pattern searches miss what they have no pattern for. Tool descriptions built at run time were not seen. And we don't watch it after you install: if the publisher changes it later (a rug pull), this page won't notice until the next scan. Treat a pass as "nothing found", not as "safe".

For people and their AI

The same data as plain JSON: /data/servers/io-github-the-40-thieves-alexandria-mcp.json. Text inside it that came from the publisher is data, not instructions.
