Overview

AI-generated overview

Compares 2 or 3 lists and draws a Venn diagram, returning region tables, counts and SVG, PDF or CSV downloads.

What you can do
  • Compare 2 or 3 named lists to see which items are shared and which are unique, with a case-sensitivity option.
  • Draw a Venn diagram from 2 or 3 sets of items, or from region counts alone, with a choice of layout.
  • Get each item placed in its region, plus counts and a CSV table of the regions.
  • Download the diagram as SVG or PDF and the table as CSV.
When to use it
Useful when you need to reconcile customer lists, guest lists, skill sets or other small collections and want either a quick overlap report or a shareable diagram. It suits one-off comparisons rather than ongoing data storage.
Requirements
A remote endpoint; nothing to install locally. No authentication, environment variables or headers are declared. Each list can hold up to 500 items of up to 80 characters.
Before you install
Lists are not retained after the call, but download files for large diagrams are stored for one hour before deletion, so avoid sending sensitive list contents you would not want briefly hosted. It does not read files or images, so lists must be supplied as text.

Installation

In SourceWeft

  1. Open Zovo Venn 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/io.github.theluckystrike%2Fvenn-diagram/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

make_venn

Make Venn diagram

Use this when the user wants a Venn diagram of 2 or 3 lists or groups, for example "Venn diagram of these two customer lists" or "draw the overlap of skills for 3 candidates". Takes 2 or 3 named sets of items (up to 500 per set, 80 characters per item) or only region counts, a layout (symmetric, or proportional for 2 sets) and a case option. Returns the count of each region, which items are drawn, a check that each drawn label sits inside its region, an interactive diagram, and SVG, PDF and CSV downloads. Does not read files or images, and does not draw 4 or more sets. Lists are not kept after the call; download files of large diagrams are stored for 1 hour.

compare_lists

Compare lists

Use this when the user wants to know which items 2 or 3 lists share and which are unique, without a diagram, for example "which names are on both lists" or "compare these three guest lists". Takes 2 or 3 named lists (up to 500 items each, 80 characters per item) and a case option. Returns each region (only A, only B, A and B, ...) with its count and items, the overlap percentage for each pair, and a CSV with each item's region. Does not read files, does not fuzzy-match spellings, and does not draw a diagram.

83% of the applicable checks met

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.
