The framing
An API platform that added agents versus an orchestration platform native to agents.
Gravitee has recently added an MCP Proxy, an LLM Proxy and, in Gravitee Gamma, an agent catalog.
Every API, model message, event stream or tool call is checked for the agent and the person it acts for. It is priced on your vendor contracts and charged back to its rightful business owner. Streams are a first class citizen just like tool calls.
The honest take
Which one fits
Choose Gravitee when you already run Gravitee API Management and you want to add agent management.
Choose Magertron when you want APIs, MCP tools, models and event streams managed in one place, with chargeback, approvals and your own policy engine, inside your cluster.
Or use both. A Gravitee-managed API can be registered in Magertron like any REST API, so your agents reach it through Magertron's permissions, policy and metering.
