MCP governance

Give every AI tool a clear permission boundary.

Your AI agents may rely on internal APIs, documentation services, ticketing systems, databases, and third-party MCP servers.

Ring Zero Security gives security and platform teams a central place to manage tool access, without relying on every agent to enforce the same rules correctly.

Disable a tool. Keep it disabled.
Switch off a tool such as read_wiki_structure, and Ring Zero Security refuses subsequent calls before they reach the MCP server.
Review new servers before they become trusted.
When an agent attempts to introduce a new MCP server, hold it for an administrator to review and approve.
Keep a record of tool activity.
See which agent called a tool, what was requested, and whether policy allowed or refused it.
EXAMPLE ADMINISTRATOR COMMAND
$ sudo rz mcp tool deepwiki-claude read_wiki_structure off
  read_wiki_structure of deepwiki-claude is now off.

If a tool is switched off, the agent shouldn't be able to talk its way around that decision.

Before your AI agents get more access, decide what they should be allowed to do.

Protect sensitive data. Control execution. Govern tools. Keep the evidence.
