What is cortex-visualize?

A command for opening an interactive visual view of Cortex’s memory and session data. Cortex is a memory system, and the visualization can show graphs, knowledge, wiki pages, boards, pipelines, and session traces.

It is for opening memory maps, codebase graphs, methodology views, workflow boards, and session-history traces.

It helps developers inspect relationships and activity visually instead of navigating stored records and logs directly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00082	$0.00740
Opus 5.5	$0.00033	$0.00296
Sonnet 5.5	$0.00016	$0.00148
Haiku 4.5	$0.00008	$0.00074

Security

Grade A, and why

cortex-visualize scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Visualize — Interactive Neural Graph (hypermnesia-mcp-viz)

Keywords

visualize, graph, neural graph, memory map, show memories, visual overview, entity graph, methodology graph, codebase graph, session trace, show profile, galaxy

Overview

Launch the interactive browser-based neural graph served by the hypermnesia-mcp-viz MCP. It reads Cortex's shared PostgreSQL store (read-only) plus your ~/.claude session history and wiki, and opens six reading angles over the same data: Trace (default), Graph (the galaxy), Knowledge, Wiki, Board, and Pipeline.

Use this skill when: the user wants a visual overview, is exploring the knowledge/codebase graph, or needs to present or screenshot Cortex's state.

Requires: the hypermnesia-mcp-viz MCP. If its tools are not available, tell the user to install hypermnesia-mcp-viz (https://github.com/cdeust/cortex-viz).

Works without Cortex: hypermnesia-mcp-viz does NOT require the Cortex memory engine to be useful. When Cortex's PostgreSQL is unreachable (or CORTEX_VIZ_NO_DB=1 is set) the server starts in no-DB mode: the Trace view — the per-session execution drill over ~/.claude session logs + git — is fully live, and the five DB-backed views (Graph, Brain, Knowledge, Wiki, Board) appear greyed out with an install pointer instead of erroring. So launch it freely even if the user hasn't installed Cortex.

Workflow

Launch the neural graph

mcp__plugin_hypermnesia-mcp-viz_hypermnesia-mcp-viz__open_visualization({})

Or filter to a specific domain:

mcp__plugin_hypermnesia-mcp-viz_hypermnesia-mcp-viz__open_visualization({ "domain": "cortex" })

Opens in the browser on a local 127.0.0.1 port. Features:

Trace — the live execution drill: domain → session → ordered prompt → action → file chain → a file's AST symbols, impact neighbourhood, and git history.
Graph — the galaxy: every project as a node cloud (setup → tools → files → discussions → memories → AST symbols), with cross-project shared-code and impact edges.
Knowledge / Board / Wiki / Pipeline — memory cards, the consolidation kanban, the browsable wiki, and the domain→stage Sankey.
Interactive — click any node for a full detail panel, drag to explore, scroll to zoom; filter by kind / domain / AST edge.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cortex-visualize is a skill published in the GitHub repository cdeust/cortex-viz (5 stars, last pushed today), licensed MIT. It adds 82 tokens to every session and 740 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
