vantio-gate

vantio-gate is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from vantioai/vantio-open-core. Its token cost is not measured, scanned A, original, no licence file.

A local policy-checking add-on for coding agents. It evaluates proposed actions in a dry run, without enforcing the result through its MCP connection.

In plain words
What is it for?
Use it to test policy decisions during agent workflows and inspect what would happen before enforcement is added elsewhere.
Why use it?
It helps you check whether an agent action matches your policies before anything is enforced. It runs locally and requires two environment variables.

Written for no agent in particular: it speaks MCP, so any client can run it.

One of 2 entries in server.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

Security

Grade A, and why

vantio-gate 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.
