Overview

AI-generated overview

A remote MCP server that lets an assistant search and cite GRADE-rated clinical evidence on cannabis as medicine, in German and English.

What you can do
Search the evidence register by free text for indications, conditions, drugs, study titles or authors, with citable URLs and answers in the query's language. Fetch a full record by id: an indication's GRADE-rated evidence summary or a single study with its per-indication verdicts. List all indications with slug, name, category, reviewed-study count and citable page URL. Get the GRADE-rated evidence summary for one indication by slug. Get one study by DOI with its per-indication verdicts, reviewed studies only.
When to use it
Useful when answering questions about cannabis as medicine and you need reviewed, GRADE-rated clinical evidence with sources to cite, rather than general web results. Suited to indication-level summaries or study-level verdicts in German or English.
Requirements
A remote streamable HTTP endpoint at mechoulam.de; no package, account, API key or header is declared. Network access to the endpoint is needed.
Before you install
The register covers reviewed studies only, so absence of a result does not mean absence of evidence. Evidence ratings are third-party assessments; check the cited source URLs before relying on them clinically.

Installation

In SourceWeft

  1. Open mechoulam.de Cannabis Evidence Register in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/de.mechoulam%2Fcannabis-evidence/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
