SULCUS ChatGPT Plugin

Official integration package connecting SULCUS Semantic Thermodynamic Memory to ChatGPT via Model Context Protocol (MCP).

SULCUS equips ChatGPT with persistent cross-session memory, proactive context recall, durable knowledge capture, and structured settings configuration.

Architecture

  • Protocol: Model Context Protocol (MCP) Streamable HTTP
  • Endpoint: https://api.sulcus.ca/mcp
  • Specification: Agent Plugins 1.0.0 (plugin.json + .codex-plugin/plugin.json)
  • App Registration: .app.json (asdk_app_6abf215bfa608191bcd028d0a3d75332)
  • Settings: Native OpenAI Structured Settings capability (settings.read, settings.update)
  • Operational Directives: skills/sulcus-setup/SKILL.md

Canonical MCP Tools

  • search_memories: Semantic and full-text search across persistent knowledge nodes
  • store_memory: Classify and persist durable facts, preferences, decisions, and procedural directives
  • get_memory: Retrieve memory node details and CCR pointers
  • update_memory: Revise existing memory nodes and reconcile contradictions
  • delete_memory: Explicit memory forgetting and graph node deletion
  • list_hot_memories: Retrieve recently active or high-heat contextual memories
  • get_user_profile: Load core user identity facts, account tier, and permanent directives
  • list_namespaces: Multi-workspace and namespace isolation

Configuration & Authentication

The plugin relies on the OpenAI Structured Settings capability exposed by the remote MCP server (settings.read, settings.update). Users configure their API key via ChatGPT's native Settings modal rather than in-chat prompts.
