Run MCP tool calls through Runestone Gatekeeper — policy enforcement, human approval, audit.
A policy-based gatekeeper service that sits between AI agents and real-world tools (shell, HTTP, filesystem), enforcing approvals, denials, USD budgets, and audit logging.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
