What your AI can do with HALLUX
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “hallux_check_command”: Call this BEFORE running any command that installs a dependency: npm, yarn, pnpm, bun, pip, uv, poetry, pipx, cargo, go get, dotnet add pack.”
“Use “hallux_check”: Does this identifier actually exist? Call before acting on any name you recalled rather than read: a package to install, a module to import,.”
“Use “hallux_check_manifest”: Call this after writing or editing a dependency file, and before committing it. Supported: package.json, requirements.txt, pyproject.toml, C.”
“Use “hallux_watch”: Register identifiers for notification when their verdict changes. The transition that matters is phantom to squat: a name models invent that.”
How secure is the HALLUX MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how HALLUX holds up.
Security grade A
gate scanned 4 tools on Sep 24, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by HALLUX (blvkware.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If HALLUX adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

hallux_check_manifest — Call this after writing or editing a dependency file, and before committing it. Supported: package.json, requirements.txt, pyproject.toml, C
hallux_watch — Register identifiers for notification when their verdict changes. The transition that matters is phantom to squat: a name models invent that
Who runs the HALLUX MCP server?
The HALLUX MCP server at a glance
https://api.blvkware.dev/hallux/mcpQuestions, answered
Is there an official HALLUX MCP server?
Yes — HALLUX operates its own remote MCP server at api.blvkware.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect HALLUX to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick HALLUX in the directory. No account or sign-in is needed. From then on, HALLUX's tools are available in every client you've connected to gate.
Do I need to host anything?
No. HALLUX runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the HALLUX MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect HALLUX in minutes. No credit card required.
