Hypermnesia MCP Viz

Hypermnesia MCP Viz is published as hypermnesia-mcp-viz everywhere: Python, MCP Registry, Claude Code, Codex, Gemini, and the console command.

The cross-platform visualization layer for Cortex. Codex, Gemini CLI, Claude Code, and any stdio MCP host can launch the same read-only server and browser UI. It turns Cortex's memory store, a host-neutral live activity stream, Claude Code's historical session archive, and your codebase graph into six live reading angles: a project galaxy, a 3D anatomical brain, an execution trace, a consolidation kanban, a curated knowledge browser, and a wiki. It never writes a memory: it renders, it never remembers. (It does keep its own derived graph/layout caches in the Cortex database, listed under Boundary.)

Launch with the openvisualization tool (or /cortex-visualize). One launcher opens six reading angles; the default landing view is Trace**.

The whole UI ships on the AI Architect design system: a paper-first reading surface with a persistent ink (night) toggle, greyscale chrome, and a data palette resolved from design tokens at runtime, flipping the surface re-inks every view in place without disturbing a settled layout, and every count on screen is exact and streamed, never rounded.

Getting Started

Claude Code users can install Hypermnesia MCP Viz from the same cortex-plugins marketplace as Cortex:

claude plugin marketplace add cdeust/Cortex
claude plugin install hypermnesia-mcp-viz@cortex-plugins

This install name becomes available in the Cortex marketplace only when this repository and the matching marketplace change in cdeust/Cortex#351 are released together. Maintainers must not publish either half of the rename on its own.

Migrating from cortex-viz

Existing Claude Code installs are not aliases for the new plugin identity. Remove the old install, refresh the marketplace after the coordinated release, and install the canonical plugin:

claude plugin uninstall cortex-viz@cortex-plugins
claude plugin marketplace update cortex-plugins
claude plugin install hypermnesia-mcp-viz@cortex-plugins

Claude composes plugin tool names from the plugin manifest name, the mcpServers key, and the tool name. Update both old full names wherever they appear in permission allowlists, hooks, skills, or agents:

Shortened. The full README is on GitHub.
