Psychedelics Knowledge Graph — questions

Answers built from our own checks of this server.

What can Psychedelics Knowledge Graph do?

It exposes 9 tools, read directly from the server on our last check. Among them: find_relationships, get_author_papers, get_concept, get_paper, get_release_info, list_available_filters and 3 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 Psychedelics Knowledge Graph working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 16 of 16 checks got a reply (100.0%), average response time 2527 ms. The bar chart above shows every period we have measured.

How do I connect Psychedelics Knowledge Graph?

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 Psychedelics Knowledge Graph need an API key?

No. Psychedelics Knowledge Graph completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

Is Psychedelics Knowledge Graph open source?

The code is open source: it is published under the Apache-2.0 licence, written in Python and 6 stars on GitHub. The licence covers the code in the repository, not the hosted service at api.psychedelicskg.com, which runs on its operator's own terms.
