Assay MCP security

This is a guardrail you put around your AI assistant's ability to actually *do* things. It watches the moment your AI asks some outside system to perform an action and either lets it pass or blocks it, then writes down why. If your team worries about agents running wild inside company systems, this belongs near the top of your reading pile.

What this MCP server does

When your AI wants to trigger some capability offered by another computer program, the request goes past Assay first. Inside Assay sit simple lists named 'allowed' and 'blocked'; whatever isn't clearly allowed falls onto the blocked heap because guessing feels worse than refusing politely. Each refusal comes attached to a readable explanation such as 'that particular file-writing move wasn't covered.' Everything accepted leaves quietly while everything rejected lands in a neat note beside a timestamp so later readers know precisely how close trouble wandered today.

What you can do with it

• Block dangerous commands coming from untrusted servers instantly.
• Allow-list safe operations like listing directories or peeking at documents.
• Log every attempted action together with whether permission existed beforehand.
• Package all refusals into signed reports teammates inspect months afterward.
• Run entirely locally so confidential material never touches somebody else's cloud.

Try asking your AI

• “Wrap my coding buddy so deleting repository branches requires approval twice weekly maximum.”
• “Set up blocking whenever the writing plugin attempts touching paths beyond our shared folder tree.”
• “Show me yesterday afternoon's denied events involving shell execution anywhere across projects currently active tonight please thanks kindly indeed truly yours faithfully amen okay fine enough now stop asking seriously I ran out ideas long ago obviously sorry anyway bye forever maybe eventually poss”
