ShieldCortex

Memory security for AI agents.

Your AI agent forgets useful context, stores untrusted context, and then confidently builds on both. ShieldCortex fixes that by giving agents memory you can inspect, review, and defend before it poisons future decisions.

npm install -g shieldcortex
shieldcortex quickstart

[!NOTE] ShieldCortex is MIT licensed and free for core local use. On first install, machines with no paid licence also get a 14-day Pro trial automatically. Team or higher is still required for cloud sync and multi-device cloud workflows.

Works with Claude Code · Codex CLI / VS Code · Cursor · VS Code · OpenClaw · LangChain · MCP agents · Python via REST API

Why teams adopt ShieldCortex

• Stop bad memory before it spreads — the 6-layer defence pipeline catches poisoning attempts, dangerous prompts, and leaked credentials before they land in durable memory
• See exactly what the agent stored and would recall — Capture, Recall, and Review turn memory from a black box into an inspectable workflow
• Keep operator control when things go wrong — contradictions, low-trust memories, duplicates, and risky agent behavior can be reviewed, suppressed, archived, pinned, or blocked

🧠 The Problem

AI agents are stateless. Every session starts from zero. Teams work around this with markdown files, custom prompts, or bolted-on vector databases. That gets memory into the system, but it does not answer the harder questions:

• what exactly was stored?
• why did this memory rank?
• what conflicts with it?
• can I trust where it came from?
• what happens if someone poisons the memory layer?

ShieldCortex replaces all of that with one install command.

🔒 What ShieldCortex Is Best At

ShieldCortex is strongest when you need an AI agent to keep useful memory without letting untrusted memory become future truth.

The core workflow is:

• Capture — inspect what the agent tried to store, where it came from, and whether it was manual, auto-extracted, or session-driven
• Recall — inspect what would rank for a query, why it ranked, and what is missing
• Review — suppress, archive, pin, canonicalize, or merge memory before it quietly shapes future output
• Protect — scan memory writes, detect prompt injection and credential leakage, and gate risky behavior with Iron Dome

That is the real product:

persistent memory for AI agents, with built-in poisoning defence and operator review

✨ What You Get

Memory you can trust

Your agent does not just store text. It gives you operator-grade visibility into what was captured, what will be recalled, and whether it is safe to trust.

• 🔍 Semantic search — finds memories by meaning using FTS5 + vector embeddings (all-MiniLM-L6-v2), not just keyword matching
• 🧭 Recall explanations — inspect why a memory ranked, including keyword, semantic, recency, tag, and link contributions
• 🎯 Recall workspace — test what an agent would retrieve, compare expected memories, and debug misses before they turn into bad answers
• 🗂️ Review queue — suppress, archive, pin, or canonicalize stale, contradictory, low-trust, or noisy auto-extracted memories
• 📥 Capture workflow — inspect what got stored, where it came from, and whether it was manual, auto-extracted, or session-driven
• 🕸️ Knowledge graph — entities and relationships extracted automatically from every memory, with readable Read, Map, and Bloom exploration modes in the dashboard
• ☁️ Cloud replica sync — opt-in local-to-cloud replication for memories and graph data, with queue diagnostics and per-project sync controls
• ⏳ Natural decay — old, unaccessed memories fade over time; important ones persist — just like human memory
• ⚡ Contradiction detection — new memories that conflict with existing ones get flagged before they cause confusion
• 🧹 Auto-consolidation — duplicate and overlapping memories merge automatically, keeping your memory store clean
• 🏷️ Memory type taxonomy — every memory gets a memoryPurpose: user, feedback, project, or reference. Categorises by purpose, not just topic
• ⏰ Staleness scoring — freshness awareness via memoryAgeDays and memoryFreshnessScore. Memories older than 2 days get staleness warnings appended during recall
• 🔀 Hybrid recall with LLM reranking — optional LLM-powered reranking after embedding-based retrieval. Configurable model and candidate limits for precision-critical workflows
• 🌐 Memory scope — memoryScope: 'private' | 'team'. Private memories stay local; team memories are shared cross-agent knowledge
• ✅ Positive feedback capture — Cortex Confirmations track what worked alongside what failed. CLI: shieldcortex cortex confirm
• 🧹 Memory save filtering — auto-filters derivable information (file paths, git refs, imports, env vars, shell commands) from being saved as memories
• 📁 Project isolation — memories scoped per project by default, with cross-project queries when you need them
• 🎞️ Incident replay — reconstruct memory and defence timelines from audit, quarantine, and retained event history
• 🔔 Webhooks — POST notifications on memory events, HMAC-SHA256 signed
• 📅 Expiry rules — auto-delete TODOs after 30 days, keep architecture decisions forever
• 🧠 Mistake learning — capture mistakes, run pre-flight checks, graduate mastered rules (Pro)

Security that shows up exactly when it matters

Every memory write passes through 6 defence layers before it's stored:

+ ✅ Input Sanitisation       → strips control chars, null bytes, dangerous formatting
+ ✅ Pattern Detection        → catches known injection patterns, encoding tricks
+ ✅ Semantic Analysis        → embedding similarity to attack corpus — catches novel attacks
+ ✅ Structural Validation    → JSON integrity, format anomalies, fragmentation attempts
+ ✅ Behavioural Scoring      → entropy analysis, anomaly detection, baseline deviation
+ ✅ Credential Leak Detection → API keys, tokens, private keys — 25+ patterns, 11 providers

Blocked content goes to quarantine for review — nothing is silently dropped.

Dependency Scanner (Pro) — detect malicious packages, typosquats, and suspicious install scripts in your project dependencies:

shieldcortex audit

Actions: quarantine flagged packages, clean confirmed threats, or auto-protect to block future installs.

Docker Install Safety — auto-detects container environments and skips plugin install to avoid gateway crashes. No configuration needed.

🚀 Quick Start

Fastest path

npm install -g shieldcortex
shieldcortex quickstart

quickstart scans your machine and auto-detects which agent tools are installed — Claude Code, OpenClaw, VS Code, Cursor, and Codex — then configures ShieldCortex for all of them in one go. One command, everything detected, no per-tool setup steps.

If you want to configure a single tool manually, use shieldcortex install instead. It registers the MCP server and session hooks for whichever agent is in the current working directory.

Verify everything works:

shieldcortex doctor

✅ Database: healthy (12.4 MB)
✅ Schema: up to date
✅ Memories: 245 total (12 STM, 233 LTM)
✅ Hooks: 3/3 installed
✅ API server: running (port 3001)

💳 Licensing and Trial

ShieldCortex has three distinct states:

• Free + MIT local core — local memory, recall, review, dashboard, Iron Dome, and OpenClaw/Codex integrations all work without a cloud account
• 14-day Pro trial — automatically starts on first install when no paid licence exists, unlocking Pro-gated local features
• Team / Enterprise cloud — required for cloud sync, shared cloud review, multi-device visibility, and team workflows

Check the current state at any time:

shieldcortex license status

Important:

• the first-run trial is automatic; there is no signup step for it
• an active paid licence always overrides the trial
• cloud sync remains Team-gated even while the local Pro trial is active
• cloud API keys are scope-based, so cloud features may still require the right key scopes in addition to the right licence tier

Always-on servers and cloud boxes

If you want a device to stay online in ShieldCortex Cloud, the machine needs a persistent ShieldCortex heartbeat, not just power.

shieldcortex service install --headless
shieldcortex service status

This installs the background worker that keeps cloud heartbeat, sync retries, and graph maintenance active on headless Linux servers.

☁️ Connect Servers to Cloud

If you want Linux servers or always-on boxes to appear as online devices in ShieldCortex Cloud, you need four things on each machine:

• the latest CLI
• a Team or higher licence
• a cloud API key with the scopes needed for sync
• the persistent headless worker service

Exact flow:

npm install -g shieldcortex@latest
shieldcortex license activate <team-key>
shieldcortex config --cloud-api-key <cloud-api-key>
shieldcortex config --cloud-enable
shieldcortex service install --headless

Verify:

shieldcortex --version
shieldcortex license status
shieldcortex config --cloud-status
shieldcortex service status

Expected result:

• Tier: Team or higher
• Cloud Enabled: Yes
• API key present
• Mode: worker
• Running: yes

Important:

• In ShieldCortex Cloud, Online means a recent ShieldCortex heartbeat, not just that the machine is powered on.
• If a server is on but still shows Offline, the usual causes are missing cloud config, missing Team licence, or an old service install.
• On headless Linux systems, you may also need:

sudo loginctl enable-linger <user>

🛡️ Iron Dome

Controls what your agent is allowed to do — not just what it remembers.

shieldcortex iron-dome activate --profile enterprise

• 🏢 Security profiles — enterprise, personal, paranoid, school
• 🚦 Action gates — allow, require approval, or block actions like send_email, delete_file, api_call
• 🔒 PII guard — detect and block personally identifiable information in outbound actions
• 🚨 Kill switch — emergency shutdown of all agent actions, immediate effect
• 📋 Full audit trail — every action check logged for forensic review

The local authenticated dashboard is treated as a trusted channel in built-in Iron Dome profiles, but dashboard write actions still go through the same announcement and confirmation tiers as CLI or MCP actions. High-risk REST mutations like config changes, SQL writes, quarantine review, and memory deletes are no longer advisory-only.

🌙 Dream Mode — Background Consolidation

Offline memory maintenance that merges near-duplicates, archives stale memories, and detects contradictions — like defragmenting your agent's brain.

shieldcortex consolidate

Dream Mode runs three passes:

• Merge — finds near-duplicate memories and combines them into a single canonical entry
• Archive — identifies stale memories that haven't been accessed or reinforced, and moves them out of active recall
• Contradict — surfaces memory pairs that conflict so you can resolve them before they cause confusion

Also available as an API call for programmatic use:

curl -X POST http://localhost:3001/api/consolidate

Schedule it nightly, run it before important sessions, or let the auto-consolidation timer handle it. Either way, your memory store stays lean and contradiction-free.

🧠 Cortex — Systematic Mistake Learning

Your agent makes mistakes. Cortex makes sure it doesn't make the same one twice.

shieldcortex cortex capture --category code --what "Guessed API endpoints" --why "Didn't check docs" --rule "Always verify endpoints in API docs before calling"

Cortex is a mistake-capture and pre-flight check system built into ShieldCortex:

• Capture — Log what went wrong, why, and the rule to prevent it
• Pre-flight — Before any task, check against your mistake database for relevant warnings
• Review — Pattern analysis across categories (code, config, process, design, security, etc.)
• Graduate — Archive rules you've mastered (30+ days, no recurrence)
• Search — Full-text search across all captured mistakes

# Before deploying, check for relevant past mistakes
shieldcortex cortex preflight --task "deploy to production"

# Weekly review — see patterns and repeat offenders
shieldcortex cortex review

# Graduate mastered rules
shieldcortex cortex graduate

Cortex data is stored locally in ~/.shieldcortex/cortex/. Pro licence required.

🐾 OpenClaw Integration

ShieldCortex is a first-class citizen in OpenClaw — the open-source AI agent framework. One command connects them:

openclaw hooks install shieldcortex
openclaw plugins install @drakon-systems/shieldcortex-realtime

This installs the hook from the main shieldcortex package and the real-time plugin from the standalone OpenClaw plugin package.

Existing installs can keep using the compatibility wrapper:

shieldcortex openclaw install

The wrapper also normalizes older hook installs by moving/removing legacy ~/.openclaw/hooks/internal/cortex-memory copies.

If the wrapper install fails with permission denied, use:

sudo "$(command -v shieldcortex)" openclaw install

Or fix ownership and retry without sudo:

sudo chown -R "$USER":"$USER" ~/.openclaw ~/.claude
shieldcortex openclaw install

This installs two components that work together:

Hook — Session Lifecycle Memory

Listens for session events and keyword triggers throughout the agent lifecycle:

• 🧠 Auto-extraction — when a session ends, high-salience content (decisions, bug fixes, learnings, architecture notes) is automatically saved to memory
• 💬 Keyword triggers — say "remember this:", "don't forget:", or "this is important:" and the content is captured immediately with the right category and importance
• 🔄 Novelty filtering — Jaccard similarity deduplication prevents the same insight from being saved twice

Plugin — Real-Time Defence

Scans every prompt and response as they flow through OpenClaw:

• 🛡️ Inbound scanning — every LLM input passes through the 6-layer defence pipeline in real time
• 📤 Outbound extraction — architectural decisions and learnings detected in assistant responses are auto-saved to memory
• 📋 Audit trail — all scans logged to ~/.shieldcortex/audit/ with full threat details

Tool Call Interceptor — Active Memory Firewall

Requires OpenClaw v2026.3.28+. Previous versions fall back to passive logging.

The plugin now watches remember and mcp__memory__remember tool calls and can block them before they execute. Content passes through the full 6-layer defence pipeline, and the outcome depends on severity:

Severity	Action	If pipeline fails
Low	Log	Allow
Medium	Warn	Allow
High	Require user approval	Deny
Critical	Require user approval	Deny

Denied calls are cached (exact-match, session-scoped, 2-hour TTL) so the same poisoned content does not re-prompt. Approval prompts are rate-limited to 5 per minute.

Configure via ~/.shieldcortex/config.json:

{
  "interceptor": {
    "enabled": true,
    "severityActions": {
      "low": "log",
      "medium": "warn",
      "high": "require_approval",
      "critical": "require_approval"
    },
    "failurePolicy": {
      "low": "allow",
      "medium": "allow",
      "high": "deny",
      "critical": "deny"
    }
  }
}

[!TIP] Auto-extraction is off by default to respect OpenClaw's native memory system. Enable it when you want both:

shieldcortex config --openclaw-auto-memory true

How they complement each other

	OpenClaw Native	+ ShieldCortex
Memory	Markdown-based	SQLite + FTS5 + vector embeddings + knowledge graph
Search	File search	Semantic search — find by meaning, not just keywords
Security	None	6-layer defence pipeline on every memory write
Decay	Manual cleanup	Automatic — old memories fade, important ones persist
Deduplication	None	Novelty gate with configurable similarity threshold
Audit	None	Full forensic log of every operation

OpenClaw handles agent orchestration. ShieldCortex handles what the agent remembers, why it remembers it, and whether it is safe to keep. Together, you get persistent, inspectable, secure memory without inventing your own memory layer.

New in the local dashboard: OpenClaw activity is no longer just a background hook. The Capture workflow includes a dedicated session view with:

• per-session saved/skipped/threat counts
• linked memories produced by that session
• session event trail from realtime audit logs
• direct review actions like pin, suppress, archive, and canonicalize
• clearer provenance so operators can tell what came from the hook, plugin, or manual capture path

📊 Dashboard

Built-in visual dashboard with keyboard shortcuts throughout — press ? to see them all.

shieldcortex dashboard

Trust Console — the new default home view. See urgent issues, knowledge coverage, cleanup pressure, and the highest-value next actions in one place.

Recall Workspace — enter a query, inspect ranked memories, see why they scored the way they did, compare an expected memory, and catch likely misses before they erode agent trust.

Review Queue — triage stale, low-trust, contradictory, projectless, and noisy auto-extracted memories with direct actions for suppressing, archiving, pinning, or marking canonical.

Capture Workflow — inspect recent memory capture activity, OpenClaw session evidence, and source trust so you can decide what should shape future recall.

The key shift is that memory is no longer a black box:

• Capture tells you what was stored and from where
• Recall tells you what will rank and why
• Review tells you what should be suppressed, archived, pinned, or marked canonical
• Shield tells you what got blocked before it could poison memory or behavior

Shield Overview — scan counts, block rates, quarantine queue, threat timeline, and memory health score.

Knowledge Graph — focus on one entity at a time, then switch between Read for relationship statements, Map for a cleaner graph canvas, and Bloom for an organic branch view.

Cloud Diagnostics — inspect local-to-cloud queue health, retry pressure, sync policy, device identity, and Team-gated cloud replica controls from the local dashboard.

Timeline — every memory, chronologically. Filter by category, type, or search. Edit memories inline.

Audit Log — full forensic log of every memory operation with trust scores and threat reasons.

New backend APIs for dashboard workflows

• GET /api/recall/explain — explain why memories ranked for a query without mutating salience or links
• GET /api/v1/incidents/replay — reconstruct a best-effort incident timeline from audit, quarantine, and retained event data
