Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

What each says it does

memX

In its own words, on Community GitHub marketplaces:

memX: local-first semantic memory for coding agents. Native Codex lifecycle hooks.

io.github.VonderVuflya/yggdrasil

One shared, durable memory for your AI coding agents — local-first, zero-dependency.

How to run each

memX As a Codex plugin

Codex
codex plugin marketplace add neoli00/memx

io.github.VonderVuflya/yggdrasil As a local MCP server: PyPI package

Claude Code
claude mcp add --env "YGG_ENGINE_TOKEN=<YOUR_YGG_ENGINE_TOKEN>" --transport stdio yggdrasil -- uvx yggdrasil-memory mcp

Requires: YGG_ENGINE_TOKEN (secret)

Commands built only from what the marketplaces declare; the full set for every client is on each card.

Tools each declares

Neither one's marketplaces publish a list of tools, so there is nothing to compare.

Settings each asks for

Only memX asks for

  • MEMX_MCP_TOOLS
  • MEMX_SECRET (secret)
  • MEMX_URL

Only io.github.VonderVuflya/yggdrasil asks for

  • YGG_ENGINE_TOKEN (secret)
  • YGG_ENGINE_URL

Settings as each marketplace publishes them. Asking for fewer is not better in itself.
