A server for storing and retrieving agent knowledge in a governed graph. It includes knowledge extraction, combining related information, hybrid search, and access tokens limited to specific scopes.

Use it to extract knowledge, merge related facts, search stored information, and manage which parts of that information an agent can access.

It gives agents a structured memory system with controlled access instead of leaving knowledge scattered across separate notes or searches.

gctrl — MCP server by GCTRL-TECH/platform

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/GCTRL-TECH/platform

Made for: Claude Code, Codex, Cursor, Gemini CLI, OpenCode.

Per session not measured What this adds to a session before it is invoked.

Security

Grade A, and why

gctrl scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gctrl is an MCP server published in the GitHub repository GCTRL-TECH/platform (7 stars, last pushed 2d ago), licensed AGPL-3.0. Its token cost is not measured: an MCP server costs its tool schemas, not its config file. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
