How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Install

How do I install the io.github.GCTRL-TECH/gctrl MCP server?

io.github.GCTRL-TECH/gctrl runs locally as an npm package, launched with npx -y gctrl-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 60 exposed · ~5,901 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
borghive_detect_communities ~103

borghive_set_privacy_mode ~176

[DEPRECATED — use 'gctrl_set_privacy_mode' instead, alias will be removed in v2] Raise a knowledge graph's privacy for cloud LLMs during setup: 'cloaked' (pseudonymize entities/PII before a cloud model sees them) or 'local_only' (never send it to a cloud model).
