Zuplo is a unified gateway designed to secure, govern, and observe all API, LLM, and MCP traffic through a single programmable policy engine. It provides a centralized solution for managing authentication, rate limits, spend caps, and audit trails across both outbound (LLM calls) and inbound (AI agent calls) traffic.

Key Features

  • Unified Policy Engine: Enforce auth, rate limits, spend caps, and audit trails across APIs, LLMs, and MCP servers from a single platform.
  • AI Gateway: Route LLM traffic, cap spend per team, and apply guardrails to model calls.
  • MCP Gateway: Govern MCP tool access for AI agents with scoped permissions and quotas.
  • MCP Server: Convert OpenAPI specs into MCP tools for seamless integration.
  • API Management: Manage API keys, rate limits, and portals with GitOps support.
  • Cost Control: Dynamic rate limiting prevents origin cost spikes and reduces spend.
  • Security & Governance: Auth, schema validation, and prompt-injection defense block abuse before it reaches your systems.
  • Visibility & Monitoring: Track every agent call, token usage, and budget consumption with detailed logs.
