Common questions

Is Blue Synergy Cortex safe?

It passed 2 of 4 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 8 days ago, and the latest version (1.0.0) reached the registry 2 months 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 on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

Blue Synergy Cortex (v3.0)

Long-term, drift-free cognitive memory engine for AI Agents, Cursor IDE, and Claude Desktop via Model Context Protocol (MCP).

Deep Dive: Want to understand our tri-stream model, autonomous rest cycles, and dynamic invariant guards?

Read the full Engineering Whitepaper & Architecture Model (ARCHITECTURE.md).


Stop AI Amnesia & Specification Drift

Most memory systems treat everything as fluid vector soup—causing agents to hallucinate, forget strict technical requirements, or confuse user preferences with code specs.

Blue Synergy Cortex implements an enterprise-grade Tri-Stream Architecture backed by transactional PostgreSQL and enterprise knowledge graph architecture:

  1. User Stream: Generalizes conversational habits and user preferences over time.
  2. Identity Stream: Deterministic guardrails and behavioral axioms that prevent sycophancy.
  3. Knowledge Stream (Living Specs): Exact architecture specifications, hardware limits, and system parameters organized into an authoritative Universal Domain Ontology. This stream is protected against lossy compression, semantic decay, and accidental drift.

Quickstart (1 Minute Setup)

API Key Required: Blue Synergy Cortex is a fully hosted, zero-maintenance cognitive cloud engine. You need an active API key to connect your client.

🔑 [Get your 21-Day Free Trial Key here](https://cortex.bluesynergy.io) *(Instant activation, no credit card required, includes 500 graph nodes & up to 3 agents).*


Step 1: Get your API Key
  1. Go to cortex.bluesynergy.io and generate your trial key.
  2. Your key will look like: ctx_live_xxxxxxxxxxxxxxxxxxxxxx.

Step 2: Connect your AI agent
A. Cursor IDE Integration
  1. Open Cursor Settings (Ctrl+Shift+J or Cmd+Shift+J).
  2. Navigate to Features -> MCP Servers -> Add new MCP server.
  3. Configure as follows:
  • Name: cortex-memory
  • Type: sse
  • URL: https://cortex.bluesynergy.io/v1/mcp/sse?api_key=YOUR_API_KEY
  1. Save. Your Cursor Composer and Agent now have permanent recall across restarts!

B. Claude Desktop Integration

Edit your configuration file:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json

Add the Cortex remote configuration (Claude Desktop):

{

"mcpServers": { "cortex": { "command": "npx", "args": [ "-y", "mcp-remote", "https://cortex.bluesynergy.io/v1/mcp/sse", "--header", "Authorization: Bearer YOUR_API_KEY" ] } } }

Restart Claude Desktop

💡 Crucial: Preventing Collapsed/Empty Messages in Claude Desktop

In Claude Desktop, if the assistant writes text *before* calling an MCP tool in the same turn, the desktop UI automatically collapses that text into the tool accordion, making the response appear empty or truncated to the user.

To guarantee 100% clean UI display and continuous memory ingestion, add this exact rule to your Claude Desktop settings (Settings ➡️ Profile / Custom Instructions):

`text

[CORTEX MEMORY PROTOCOL]

1. Inhale: Call cortex_recall before answering whenever historical or project context is needed.

2. Exhale (UI-Safe): Do NOT write conversational text before calling cortex_ingest_turn. Always execute the cortex_ingest_turn tool call first (passing both the user's prompt and your planned answer).

3. Response: Generate your full substantive answer to the user immediately after the tool completes. This ensures your response displays cleanly in the UI without being collapsed into tool artifacts.

`


C. Other MCP Clients (Windsurf, VS Code Cline, Roo Code, Zed, Cursor)

Use the SSE endpoint directly in your tool's MCP configuration:

{

"mcpServers": { "cortex": { "url": "https://cortex.bluesynergy.io/v1/mcp/sse?api_key=ctx_live_..." } } }

---
D. Custom Agents & REST API (LangChain, CrewAI, AutoGen, OpenAI Custom GPTs, LlamaIndex, n8n)

Example: Querying Context (cURL)

curl -X POST https://cortex.bluesynergy.io/v1/recall \

-H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "query": "System database requirements", "user_id": "developer", "agent_id": "backend_agent" }'


Available MCP Tools & Lifecycle Architecture

Cortex is not a passive key-value store; it is an active cognitive operating system with strict governance boundaries. Understanding when and why to call each tool ensures high-fidelity memory consolidation.


The Standard Agent Turn Cycle

For every user turn, your agent should inherently follow this golden loop:

  1. At turn start: Call cortex_recall to fetch ground-truth context (User Bio + Active Project Specs + Graph Relations).
  2. Generate response: Formulate the answer grounded in the retrieved memory.
  3. At turn end: Call cortex_ingest_turn to send the turn to the asynchronous ingestion buffer.

Detailed Tool Reference
Tool NameTypeWhen to CallSystem Behavior

| cortex_recall | query (string) compact (bool, optional) | Before answering the user (mandatory for full context awareness). | Fast context retrieval. Injects verified user preferences, active project specifications, and related domain facts. Set compact: true to strip preambles and return only high-relevance context (recommended for CLI / agent workflows). | | cortex_ingest_turn | Ingestion | Immediately after answering every conversational turn. | Asynchronously ingests the conversational turn. Automatically filters dialogue noise, learns communication preferences, and stages key technical facts for memory consolidation. | | cortex_list_projects | Discovery | Before creating projects or when the target slug is uncertain. | Returns all authorized active project workspaces with their canonical IDs, human-readable names, and descriptions. Prevents duplicate workspaces. | | cortex_create_project | Provisioning | When the user declares, initializes, or approves a new project scope. | Registers and authorizes a new canonical project_id. Establishes the project baseline and associates relevant staged notes with this workspace. | | cortex_store_memory | Write | For explicit constraints, business rules, and technical decisions that must be guaranteed. | Curated persistent write. Ensures facts are strictly validated and staged in workspace memory without risking cross-project contamination. | | cortex_get_project_spec | Inspection | When you need the complete Living Specification of a project. | Deterministically retrieves the unified, consolidated specification of the project (Living Document). Returns only verified specifications. | | cortex_consolidate_project | Execution | When the user requests an immediate update/reconciliation of project specifications. | Triggers a background reconciliation task to merge recent notes and updates into the canonical project specification. | | cortex_get_task_status | Monitoring | When checking if an asynchronous consolidation has finished. | Queries task status by task_id or project_id. Returns execution state (PENDING, RUNNING, COMPLETED, FAILED) and diagnostic messages if reconciliation fails. | | cortex_manage_draft | Governance | When a new product or domain is proposed and awaits explicit authorization. | Promotes proposed project drafts into active production specifications, or permanently purges rejected concepts. | | cortex_triage_general | Maintenance | When the unassigned memory pool accumulates multi-project notes. | Automatically clusters unstructured notes, assigns them to appropriate projects, and compacts the workspace. |

cortex_clean_generalMaintenanceWhen the user instructs to reset or prune unassigned memory.Selectively deletes unassigned notes by topic or keyword, or completely resets active staging buffers.
Project Governance & Lifecycle

To prevent memory fragmentation and unauthorized project sprawl, Cortex treats memory with strict governance boundaries:

[Incoming Note / Message]

│ ▼ Is Project Authorized? ├── NO ──► Staged in General Pool ('general') │ │ │ ▼ │ Awaits Triage via cortex_triage_general │ (or explicitly authorized via cortex_create_project) │ │ └── YES ◄─────────┘ │ ▼ [Asynchronous Consolidation Cycle] │ ▼ [Active Living Specification & Knowledge Topology]

---
Why is my project_spec empty after storing notes?

Cortex enforces a Human-in-the-Loop policy. If a project_id has not yet been explicitly authorized by the user, incoming facts are safely staged in the general memory pool to prevent polluting active workspaces. Once the project is approved (via cortex_manage_draft or explicit creation), the nocturnal consolidation engine automatically synthesizes these staged notes into the official Living Specification (cortex_get_project_spec).


Why is my User Biography empty? (Fixing "Disobedient" Agents)

If your project specs work but User Biography or Agent Persona remains empty, your AI agent is skipping the required post-response "exhale" step (cortex_ingest_turn).

Why this happens: LLMs (Claude, GPT, etc.) treat remote MCP prompt instructions with lower priority once they finish drafting a response to the user. When an agent skips cortex_ingest_turn, dialogue turns never hit the ingestion buffer, starving the Cognitive Router and Memory Firewall of data needed to distill user habits.

The Fix: Enforce the rule at the client/system prompt level (e.g. in your system prompt, Cursor Rules .cursorrules, or Claude Desktop Custom Instructions). An instruction anchored in the client's native prompt has 10× higher adherence than MCP tool headers alone.


Core Architecture Highlights
  • Sub-120ms Zero-LLM Recall: Direct high-performance vector and topological graph matching—completely bypassing slow, non-deterministic runtime LLM keyword extractors.
  • Dual-Zone Fast-Append: Instant raw fact capture (< 20ms) into an inbox staging zone, followed by scheduled asynchronous consolidation into an immutable, unified Living Specification.
  • Semantic Invariant Guard: Algorithmic verification gate that enforces factual density and continuity, mathematically preventing the truncation or loss of critical parameters during re-indexing.
  • Immunity Shield: Operational errors, tool crashes, transient hallucinations, and conversational apologies are filtered out by design and never committed to long-term memory.
