Nyxa Governed Memory MCP

Nyxa Governed Memory MCP is an MCP-compatible AI Governance Apprentice for governed memory workflows. Governed memory means memory that is classified, sensitivity-aware, auditable, consent-aware, and not automatically treated as confirmed truth.

This project uses MCP as a connector layer, not as the product itself. The product framing is governance-first: observe, classify, document, and keep humans in control of validation and decisions.

What This Is

Nyxa AI Governance Apprentice helps teams structure AI-adjacent memory and audit workflows with explicit policy checks and audit traces.

It is designed for:

• governed memory classification
• open-signal handling
• risk documentation
• audit trail generation
• human-supervised AI workflows

What This Is Not

Public MVP boundaries:

• no autonomous interpretation
• no autonomous action execution
• no confirmed memory without validation
• no biometric processing
• no dream interpretation
• no clinical, psychological, or legal advice
• no hidden side effects

Core Invariants

• open_signal is not memory_node.
• Unvalidated memory candidates are not confirmed truth.
• Human operators remain responsible for decisions, validation, and deployment controls.
• Legal evidence package preparation means organization/documentation support, not legal advice.

Current Active Tools (v0.1)

The currently active tool surface is intentionally minimal:

• system.status
• policy.mode
• audit.trace

Planned Public MVP Tool Surface (Roadmap, Not Yet Active)

The following governance-oriented tools are planned for public MVP expansion and are not active in v0.1:

• classify_event
• classify_sensitivity
• create_audit_note
• export_governance_report
• prepare_legal_evidence_package
• hold_open_signal

MCP Connector Example

{
  "mcpServers": {
    "nyxa-governed-memory": {
      "command": "node",
      "args": ["/absolute/path/to/nyxa-governed-memory-mcp/dist/index.js"],
      "env": {
        "NYXA_AGENT_MODE": "observe_only",
        "NYXA_MEMORY_BACKEND": "local",
        "NYXA_DATA_DIR": "/absolute/path/to/nyxa-governed-memory-mcp/data"
      }
    }
  }
}

Safe-By-Default Boundaries

• default mode: observe_only
• policy enforcement before every tool call
• audit event written for every tool call
• execution tools disabled
• authoritative writes disabled

Submission Readiness

This repository is structured for governance-first MCP/connector submission with:

• explicit security and privacy statements
• documented governance invariants
• threat model and limitations
• EU/GDPR alignment notes (design alignment, not certification)
• controlled, minimal tool exposure in current release
