Overview

Description from the maker (original English)

Immutable agent diagrams: create, edit, validate and render versioned diagrams over MCP.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • diagram_find

    Lists this workspace's diagrams, latest version first, each with its family and brief's first line. query matches the title, key or brief, ignoring case; title matches come first.

  • diagram_get

    Reads a diagram. The default outline: a header (id, title, revision, time, hash), the brief, recent versions, one element per line nested by container, and edges as 'id: from -> to'. view 'dsp' returns the scene JSON, 'mermaid' Mermaid to edit and send back to diagram_edit. revis

  • diagram_validate

    Checks a DSP scene or Mermaid text without saving it. Returns ok, errors and warnings, each with a code, the element if any, and a one-line fix.

  • diagram_create

    Saves a new diagram from a DSP scene or Mermaid text; returns its id, revision 1 and hashes. key is your stable name for it, unique in the workspace: your repeat with the same key and content returns the existing diagram, not a copy. brief stores context for the next agent. Versi

  • diagram_edit

    Changes a saved diagram as a new revision; old ones stay. Give baseRevision (the revision you last read), a one-line message, and ops (typed operations, https://zindex.ai/schemas/ops.schema.json), mermaid (the whole diagram edited from view mermaid; only differences apply), resto

  • diagram_render

    SVG and PNG links to a version, not the image, with its size, date, hashes and engine version. A published diagram's links, and a version link's, last until the link is revoked, or the diagram made private or deleted (then NOT_FOUND); url is its page. Others last 7 days. A versio

  • diagram_history

    Lists a diagram's versions, newest first, with time, who made it (by), client, message, chain hash and counts of elements added, changed and removed. compare (from and to: revision numbers or dates) returns what changed between two versions instead.

  • diagram_delete

    Deletes a diagram with all its versions. undo restores it within 24 hours; after that it is gone. Asks the user to confirm.

  • diagram_share

    publish makes a diagram readable by anyone at its link; unpublish makes it private. link makes a share link showing its images, not its scene, to anyone who has it; unlink revokes them all. report sends one version to Zindex support. feedback sends Zindex staff a bug, docs (the d

Common questions

Is Zindex safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (7.1.1) reached the registry 19 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
