These tools monitor, authenticate, and secure the connections between APIs and the systems they interact with, ensuring that only authorized users and systems can access the data or services offered by the API. Features typically include encryption, rate limiting, authentication (such as OAuth, JWT), API traffic monitoring, threat detection, and automated security testing.

    Gravitee is an AI agent management and API management platform designed to secure, observe, and govern interactions between AI agents, models, APIs, event streams, and enterprise services. Its AI Gateway provides centralized control for LLM traffic, MCP tool access, and agent-to-agent communication through LLM Proxy, MCP Proxy, and A2A Proxy capabilities. The platform can enforce authentication, authorization, least-privilege access, PII redaction, rate limits, spending controls, and audit logging across AI traffic. Gravitee also provides visibility into agent behavior, token consumption, dependencies, costs, and usage patterns so organizations can identify shadow AI and unmonitored workloads. Beyond AI governance, the platform manages APIs and event streams, including REST, GraphQL, gRPC, Kafka, and related enterprise integration patterns. Gravitee is designed for organizations that want a unified control layer for AI agents, APIs, events, and model access.
