Ground Control (GCTRL)
The knowledge-infrastructure layer for enterprise AI.
Ground your data. Command your AI.
GCTRL turns your scattered documents, databases, and code into one governed knowledge graph — then grounds your LLMs and agents on it, with enterprise-grade access control, entirely on your own infrastructure.
Most "AI memory" is a pile of vector chunks: fuzzy recall, no structure, no provenance, no permissions. GCTRL is graph-native — entities, typed relations, dossiers, and hybrid retrieval — and it runs 100% locally, so nothing leaves your building.
The pitch in one line: point GCTRL at your data, get a governed knowledge graph, and let any agent (Claude Code, Cursor, Codex…) read and write it as durable, access-controlled memory.
✨ Why GCTRL
- 🕸️ Graph-native, not a vector blob. Entities, typed relations, entity dossiers, and hybrid retrieval (dense + keyword + graph traversal) — with provenance on every fact. Ask "how does X connect to Y?" and get a real answer, not a fuzzy guess.
- 🔒 100% self-hosted, local inference. Runs on your hardware with local Ollama. DSGVO/GDPR by design — RAG sessions live in browser memory, no conversation is stored server-side, no data leaves your network.
- 🛡️ Access control built for the enterprise. Per-element classification and clearance, scoped colleague tokens, airtight multi-project isolation, and a full audit trail. Designed ISO 27001-aware, with TISAX Level 3 as the north star.
- 🤖 Drop into any agent. One MCP config and Claude Code, Cursor, Codex, or any MCP client gets durable, governed, graph-native memory — plus a built-in Pi agent.
- ⚙️ Self-maintaining memory. Heat/decay/trust scoring, semantic dedup, community detection, and an auto-curated wiki keep the graph clean and useful over time.
- 🎯 Near-SOTA entity resolution — unsupervised and on-device. The fusion core resolves duplicates and contradictions across systems without labels and without the cloud.
🧩 The platform
GCTRL is four modules over one graph, plus an agent layer:
🚀 Quick start
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
Install directly
Runs npx -y gctrl-mcp on your machine. Read the scan report first; the gateway never runs local packages.

Gctrl: common questions
- Is Gctrl MCP server safe?
- Mostly: it is graded B (82/100). Read the Gctrl safety report
- How do I install Gctrl?
- It runs on your machine. Copy the Claude Code, Claude Desktop or Cursor config from the install section.
- Does Gctrl need an API key?
- Yes. The registry entry asks for
GCTRL_API_TOKEN. - Is Gctrl maintained?
- The last commit was in the last day (2026-09-20). The latest release is v1.2.0.
- What can I use instead of Gctrl?
- Servers from other publishers that do the same job: Total Agent Memory MCP server, rag-rat MCP server and GrayMatter MCP server. Compare all Gctrl alternatives.
